a = –5

Solution:

Given data: [tex]y=-\frac{1}{2}ax[/tex], [tex]m=\frac{5}{2}[/tex]

The standard equation of a line is y = mx + c.

In the line [tex]y=-\frac{1}{2}ax[/tex] can be written as [tex]y=-\frac{1}{2}ax+0[/tex].

The slope of the line [tex]y=-\frac{1}{2}ax+0[/tex] is [tex]m=\frac{-1}{2}a[/tex].

Given [tex]m=\frac{5}{2}[/tex].

Both are slopes of the line. So,we can equate the both slopes.

⇒ [tex]\frac{-1}{2}a=\frac{5}{2}[/tex]

⇒ [tex]a=\frac{5}{2}\times\frac{-2}{1}[/tex]

⇒ a = –5

Hence the value of a is –5.

Answer:

  t = 36

Step-by-step explanation:

If one of the roots is "a", the equation can be factored as ...

  (5x -a)(x -a) = 0

  5x^2 -6ax +a^2 = 0

Comparing terms to the given equation, we see that ...

  -6ax = -36x

  a = 6 . . . . . . . . divide by -6

Then ...

  a^2 = t

  36 = t . . . . . . . substitute 6 for a

The roots are 6 and 6/5.

Margot needs 3/4 pounds of turkey to make 1 liter of turkey chili. To make 4 liters of turkey chili, which is 4 times the recipe, she will need 3 pounds of turkey.

Margot used 1/2 pound of turkey to make 2/3 liters of turkey chili. To find out how much turkey she will need for 4 liters of turkey chili (4 times the 1-liter recipe), we need to calculate the amount of turkey needed per liter first and then multiply it by 4.

First, we determine the amount of turkey needed for 1 liter by setting up a proportion. Since 1/2 pound of turkey makes 2/3 liters, we have:

1/2 pound / (2/3) liter = x pounds / 1 liter

By cross-multiplication, we find that x = (1/2) * (3/2) = 3/4. Therefore, Margot needs 3/4 pounds of turkey for 1 liter of chili.

To make 4 times the recipe, or 4 liters, Margot will need 4 * 3/4 pounds of turkey = 3 pounds of turkey.

[tex]\frac{8}{35}[/tex] of all claims were paid in the second month.

Step-by-step explanation:

Step 1; In the first month [tex]\frac{3}{7}[/tex] of all expenses were paid. So to find the expenses that were not paid in the first month we subtract [tex]\frac{3}{7}[/tex] from 1 i.e. 1-[tex]\frac{3}{7}[/tex]= [tex]\frac{4}{7}[/tex]. So in the first month  [tex]\frac{4}{7}[/tex] of total expenses were not paid.

Step 2; In the second month [tex]\frac{2}{5}[/tex] of the remaining claims were paid i.e. [tex]\frac{2}{5}[/tex] of the remaining claims which is  [tex]\frac{4}{7}[/tex] of the total claims. So to find out the number of claims paid in the second month it's just a case of multiplying [tex]\frac{2}{5}[/tex] with [tex]\frac{4}{7}[/tex].

Fraction of all claims paid in second month = [tex]\frac{2}{5}[/tex]  * [tex]\frac{4}{7}[/tex]= [tex]\frac{8}{35}[/tex].

Example; If $ 70,000 was the total claim amount, [tex]\frac{3}{7}[/tex] of that which equals $30,000 was paid in the first month. So $40,000 was still to be paid. In the second month [tex]\frac{2}{5}[/tex] of $40,000 was paid which equals $16,000 paid in the second month which is [tex]\frac{8}{35}[/tex] of total claims i.e. $70,000

Answer:

The ratio of food costs to take home is 1 : 6.

Step-by-step explanation:

Given:

Carol's monthly take home pay is 1500$. She spends $250 a month on food.

Now, to find the ratio of food costs to take home pay.

Take home pay = $1500.

Cost of food = $250.

So, getting the ratio:

Cost of food : take home pay

$250 : $1500

[tex]=\frac{250}{1500}[/tex]

[tex]=\frac{1}{6}[/tex]

[tex]=1:6[/tex]

Therefore, the ratio of food costs to take home is 1 : 6.

Final answer:

Carol's food costs to take home pay ratio is 1:6, meaning for every six dollars she takes home, she spends one dollar on food.

Explanation:

To calculate the ratio of Carol's food costs to her take home pay, we compare the amount she spends on food to her total monthly take home pay. This can be represented by the ratio 250:1500 or simplified by dividing both numbers by the common factor of 250, which results in the simplified ratio of 1:6. Hence, for every dollar Carol takes home, she spends about one-sixth of it on food.

Answer:

Each side of the frame is 12.35 centimeters long.

Answer:

Step-by-step explanation:

9x+3y=420  ---------- (eq1)

1x+6y=296 -----------(eq2)

to solve by elimination, we first multiply (eq 1) by 2

(eq1) x 2

2(9x+3y)=2 (420)

18x + 6y = 840 -----(eq 3)

eliminate y term by subtracting (eq2) from (eq3)

(eq 3) - (eq 2)

(18x + 6y) - (1x+6y) = 840 - 296

18x + 6y - 1x-6y = 544

18x - 1x = 544

17x = 544 (divide both sides by 17)

x = 544/17 = 32

Since you said that you are not looking for the answer, i will stop here, but to get the y value, subtitute the value of x which we found, back into eq 1 or 2 to find y

Answer:

$13,287

Step-by-step explanation:

As per question, Soft Shoes has sold blue slippers last week for $1,528 which is 11.5% of total sales, In order to find their total sales let us assume that their total sales is 'y'. Now in the form of an equation we write the above statement as:

11.5% of y = $1,528

or

[tex]\frac{11.5}{100}y[/tex] = $1,528

or

0.115 y = $1,528

Dividing the equation by 0.115, we get:

y = [tex]\frac{1528}{0.115}[/tex]

y = $13,286.96

Rounding to the nearest dollar we get:

y = $13,287

Hence their Total Sales will be $13,287.

The vertex is [tex](-1,1)[/tex]

Explanation:

The equation is [tex]f(x)=2x^{2} +4x+3[/tex]

To find the vertex, we need the equation in the form of [tex]f(x)=a (x-h)^{2}+k[/tex]

Dividing each term by 2 in the equation [tex]f(x)=2x^{2} +4x+3[/tex]

[tex]f(x)=2(x^{2} +2x+\frac{3}{2} )[/tex]

Now, completing the square by adding and subtracting 1, we get,

[tex]f(x)=2(x^{2} +2x+1-1+\frac{3}{2} )[/tex]

The first three terms can be written as [tex](x+1)^{2}[/tex],

[tex]f(x)=2[(x+1)^{2}+\frac{1}{2} ][/tex]

Multiplying 2 into the bracket, we get,

[tex]f(x)=2(x+1)^{2} +1[/tex]

This equation is of the form [tex]f(x)=a (x-h)^{2}+k[/tex]

Now, we shall find the vertex [tex](h,k)[/tex]

Thus, [tex]h=-1[/tex] and [tex]k=1[/tex]

Thus, the vertex is [tex](-1,1)[/tex]

y = -5x + 29 is the equation of line in slope intercept form for the line that passes through (5, 4) and (6,-1)

Solution:

Given that, line that passes through (5, 4) and (6,-1)

To find: Equation of line in slope intercept form

Let us first find the slope of line

The slope of line is given by formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here given points are (5, 4) and (6, -1)

[tex](x_1, y_1) = (5,4)\\\\(x_2,y_2) = (6, -1)[/tex]

Substituting the values in formula,

[tex]m =\frac{-1-4}{6-5}\\\\m = \frac{-5}{1}\\\\m = -5[/tex]

The equation of line in slope intercept form is given as:

y = mx + c ------------ eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

To find y - intercept, substitute m = -5 and (x, y) = (5, 4) in eqn 1

4 = -5(5) + c

4 = -25 + c

c = 29

Substitute m = -5 and c = 29 in eqn 1 to get equation of line

y = -5x + 29

Thus equation of line in slope intercept form is found

Answer:to find the difference between 6/8 and 1/7, you need to make the denominators (the bottom numbers) the same. turn 6/8 into 42/56. then turn 1/7 into 8/56. you’ll then do 42/56-8/56. so it’ll be 42-8=36. so it will come out to 36/56, which is (when simplified) is 9/14. your answer will be 9/14.

Step-by-step explanation:

Answer: 1) 56 cents. 2) 30 CDs

Step-by-step explanation:

1.68 ÷ 3 = 56 cents

60 x 7 = $420

$420/ 14 = 30 CDs

The price per ounce of tomato sauce is 56 cents. Edward can buy 30 CDs for $14 each with the same amount that would buy 60 CDs for $7 each.

To calculate the price per ounce, we take the total cost of the can in cents, which is $1.68 or 168 cents, and divide it by the number of ounces, which is 3 ounces. Thus, the price per ounce is: 168 cents / 3 ounces = 56 cents per ounce.

Edward wants to spend the same amount to buy CDs at $14 each as he would buying 60 CDs at $7 each. The total cost for 60 CDs at $7 each is: 60 CDs x $7/CD = $420. We divide this total cost by the price of one CD at $14: $420 / $14/CD = 30 CDs. Therefore, Edward can buy 30 CDs for $14 each with the same amount of money.

This is a combinatorial geometry problem involving the probability of forming a triangle with an integer area from randomly selected lattice points within a square grid. It requires analyzing the properties of lattice point triangles and applying combinatorial mathematics.

The problem given discusses the selection of random points within a square on a coordinate system to form a triangle, and it questions the probability of the triangle's area being an integer. This involves combinatorics, geometry, and number theory within the field of mathematics. To approach the problem of calculating the probability that the area is an integer, one must consider the distribution of lattice points and use combinatorial analysis.

Area of a triangle with vertices at lattice points can be expressed using the formula derived from the determinant of a matrix. The triangle's area, if non-degenerate, can be half of the odd integer, which upon doubling to remove the half, leaves an integer area. Thus, the problem reduces to a combinatorial question concerning lattice points, selected at random, and forming a triangle whose twice the area is an odd integer.

However, a direct count of the favorable vs. total possibilities may be complex due to the large number of possible point combinations and the chance of degenerate triangles (where the area is zero). Thus, a systematic probabilistic and combinatorial approach is necessary to resolve this question, likely involving a careful analysis of the geometric configurations and properties of integer triangles on a lattice grid.

Answer:

[tex]p(Not\ 5) = \frac{8}{9}[/tex]

Step-by-step explanation:

Given:

Txo six-sided dice are rolled.

Total number of outcomes n(S) = 36

We need to find the probability that the sum is not equal to 5 p(Not 5).

Solution:

Using probability formula.

[tex]P(E)=\frac{n(E)}{n(S)}[/tex]  ----------------(1)

Where:

n(E) is the number of outcomes favourable to E.

n(S) is the total number of equally likely outcomes.

The sum of two six-sided dice roll outcome is equal to 5 as.

Outcome as 5: {(1,4), (2,3), (3,2), (4,1)}

So, the total favourable events n(E) = 4

Now, we substitute n(E) and n(s) in equation 1.

[tex]P(5)=\frac{4}{36}[/tex]

[tex]p(5) = \frac{1}{9}[/tex]

Using formula.

[tex]p(Not\ E) + p(E) = 1[/tex]

[tex]p(Not\ 5) + p(5) = 1[/tex]

Now we substitute p(5) in above equation.

[tex]p(Not\ 5) + \frac{1}{9} = 1[/tex]

[tex]p(Not\ 5) = 1-\frac{1}{9}[/tex]

[tex]p(Not\ 5) = \frac{9-1}{9}[/tex]

[tex]p(Not\ 5) = \frac{8}{9}[/tex]

Therefore, the sum of two six-sided dice roll outcome is not equal to 5.

[tex]p(Not\ 5) = \frac{8}{9}[/tex]

The length of ladder is 17 feet

Solution:

Given that, ladder touches a wall 15 ft off the ground, and the base of the ladder is 8 feet from the base of the wall

To find: length of ladder

The ladder, wall and ground forms a right angled triangle

Where, ladder is "hypotenuse" and "ground' forms the base

The figure is attached below

ABC is a right angled triangle

AC = length of ladder = ?

AB = height of wall = 15 feet

BC = distance between base of ladder and base of wall = 8 feet

Apply pythogoras theorem for right angled triangle

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above theorem,

[tex]AC^2 = AB^2+BC^2[/tex]

Substituting the values we get,

[tex]AC^2 = 15^2 + 8^2\\\\AC^2 = 225 + 64\\\\AC^2 = 289\\\\\text{Take square root on both sides }\\\\AC = \sqrt{289}\\\\AC = 17[/tex]

Thus length of ladder is 17 feet

Step-by-step explanation:

The interval of 0-19 will increase by 20 of either Hay Bale Toss or Pie Eating Contest.

A histogram is a visual representation of statistical data that makes use of rectangles to illustrate the frequency of data items in a series of equal-sized numerical intervals. The independent variable is represented along the horizontal axis and the dependent variable is plotted along the vertical axis in the most popular type of histogram.

Given that, a class of 20 students is visiting the fair today. Each student is 16 years old or younger and will participate in either the Pie Eating Contest or the Chili Cookoff.

Number of students visiting the fair = 20

Age group = 0-16

In the histogram, this age group falls in the first interval which is 0-19.

If all 20 students joined the Hay Bale Toss then the bar of 0-19 of Hay Bale Toss will increase from 40 to 60 and the graph of Pie Eating Contest will remain the same.

If all 20 students joined the Pie Eating Contest then the bar of 0-19 of Hay Bale Toss will increase from 20 to 40 and the graph of Hay Bale Toss will remain the same.

Therefore, only one if the graph's interval of 0-19 will increase by 20 whereas the other graph would remain the same.

40%

Step-by-step explanation:

First, divide 100 by 20. You do this because you need something out of 100 to equal a percent. (Example- 50 out of 100 is 50%)

Next you need to take the number you got from dividing (5) and multiply that with 8. This leaves you with 40/100 or 40%.

Hope this helps!

-Coconut;)

Answer:

40%

Step-by-step explanation:

The total number of students are '20'. Moreover the number of boys out of that 20 students are '8'.

So to find the percentage of the number of boys, take 8 (number of boys) divided by 20 (the total) and times that by 100, which will give you the percentage.

This is how it goes...

[tex]\frac{8}{20}[/tex] × 100 = 40%

∴ 40% of the class is made up of boys.

Answer:

The height of the triangle is: [tex]H = (5x^2 + x +3)[/tex]

Step-by-step explanation:

Here, the area the triangle  is given as: [tex]15x^4 + 3x^3 + 4x^2 - x - 3[/tex]

Also, base of the triangle  = [tex](6x^2 -2)[/tex]

Let us assume the height of the triangle = H units

Now, AREA of TRIANGLE =  [tex]\frac{1}{2} \times B \times H[/tex]

[tex]\implies (15x^4+3x^3+4x^2-x-3 ) = \frac{1}{2} \times ( 6x^2-2) \times H\\\implies H =\frac{ (15x^4+3x^3+4x^2-x-3 )}{(3x^2-1)}[/tex]

Solving by LONG DIVISION, we get:

[tex]H = (5x^2 + x +3)[/tex]

Hence, the height of the triangle is: [tex]H = (5x^2 + x +3)[/tex]
