Numbers 3-4, you already have the name, BUT you have to classify if the sides are equal. So, for 3-4 ALSO put, “ top and bottom are equal “ or “sides are the same” so for the rhombus, as an example, say, “all sides are the same”..understand?

Answer:

5.32255

Step-by-step explanation:

if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.

It is the closely curving line drawn from the center to an equally distant point. The distance separating a circle's center and perimeter is its radius.

Let r be the radius of the circle. Then the area of the circle is written as,

A = πr² square units

The area of the circle is 89 square feet. Then the radius of the circle will be given as,

89 = πr²

Simplify the equation, then the radius is written as,

πr² = 89

r² = 28.34

r = 5.32 feet

if the circle's surface area is 89 square feet. The circle's radius will then be 5.32 feet.

13 - 6 is 7

7 + 6 = 13

Just subtract the 2 numbers and you get your answer.

Final answer:

The equation 13 = 6 + y is solved by subtracting 6 from both sides, yielding y = 7.

Explanation:

To solve for y in the equation 13 = 6 + y, we need to isolate y on one side of the equation. We can do this by subtracting 6 from both sides of the equation.

Here is how you can solve the equation step by step:

Start with the original equation: 13 = 6 + y.

Subtract 6 from both sides: 13 - 6 = 6 + y - 6.

This simplifies to: 7 = y.

So, the value of y is 7.

Answer:

Step-by-step explanation:

Pete played 18 tennis matches in a week.

P = 18

Jack played 6 fewer matches than Pete.

J = P - 6

J = 18 - 6

J = 12

How many times the number of matches pete played is the number of matches jack played?

18 / 12 = 1.5

Pete played 1.5 times the number of matches that Jack played.

Answer:

Pete played 1.5 times the amount of matches Jack did.

Step-by-step explanation:

In order to find this, first find the number that Jack played. Since he played 6 fewer than Pete we can solve by subtracting 6 from Pete's number.

18 - 6 = 12

Now to find how many more times higher it is, divide the number Pete does by Jack's number. 18/12 = 1.5

Step-by-step explanation:

900 = 750 + 2*75. In other words, 900 is 2 standard deviations away from the mean. Similarly, 975 is 3 standard deviations from the mean. So

[tex]P(900<X<975)=P(2<Z<3)[/tex

where [tex]X[/tex] is the random variable for the lifespan of a light bulb with the given normal distribution, and [tex]Z=\dfrac{X-750}{75}[/tex] with the standard normal distribution.

We get

[tex]P(2<Z<3)\approx0.0214=2.14\%[/tex]

If you don't have a calculator/lookup table available, you can invoke the empirical rule, the one that says

[tex]\begin{cases}P(-1<Z<1)\approx68\%\\P(-2<Z<2)\approx95\%\\P(-3<Z<3)\approx99.7\%\end{cases}[/tex]

The normal distribution is symmetric about its mean, so we also know

[tex]\begin{cases}P(0<Z<1)\approx34\%\\P(0<Z<2)\approx47.5\%\\P(0<Z<3)\approx49.85\%\end{cases}[/tex]

Then

[tex]P(2<Z<3)=P(0<Z<3)-P(0<Z<2)\approx2.35\%[/tex]

Answer:

0.021

Step-by-step explanation:

One way in which to approach this problem solution is to use a calculator that has statistical distribution functions built in.  My old TI-83Plus has the function "normalcdf," which does the job nicely.

Typing in normalcdf(900,975,750,75) results in the probability 0.021 that a light bulb chosen at random will last between 900 and 975 hours.

Using a table of z-scores would be a good alternative approach.  Note that the z-score corresponding to 750 hours is 0; that for 900 is +2; and that for 975 is +3.  Find the area under the standard normal curve to the left of 975 (z = 3) and that to the left of 900 (z = 2), and then subtract the two results.  It will be 0.021, as before.

Answer:

x1 = - 4

x2 = 2/3

Step-by-step explanation:

Divide the equation by 3 to give

x^2 + 10x/3 + c/3 = 0

The sum of the two roots = - 10/3

So

x1 + x2 = -10/3

x1 - x2 = 4 2/3                Add these two equations.

2x1 = -10/3 + 4 2/3         Change 4 2/3 to an improper fraction

2x1 = -10/3 + 14/3            Combine the right

2x1 = 4/3                         Divide by 2

2x1/2 =4/3//2        

x1 = 2/3

=====================

x1 + x2 = - 10/3

2/3 + x2 = - 10/3

x2 = - 10/3 - 2/3

x2= -12/3

x2 = - 4

=================

(x - 2/3)(x +4) = 0              Multiply through by 3

(3x - 2)(x + 4) =0

==============

Check

(3x - 2)(x + 4) = 0

3x^2 + 12x - 2x - 8 =0

3x^2 + 10x - 8 = 0

Answer:

See possible solutions below.

Step-by-step explanation:

The equation x^2 = 36 is a polynomial equation.

It can be solved by using a radical on both sides. The solution is x = +/- 6.

The equation has two solutions. x = -6, 6.

While this is a polynomial equation, it is specifically called a quadratic since the exponent is 2.

The equation x^2 = 36 has two real number solutions: x = 6 and x = -6. Statements that acknowledge both of these solutions as possible would be true.

The equation in question is x^2 = 36. To solve this equation, one must realize that there are two real number solutions since squaring either a positive or negative number will result in a positive number. Taking the square root of both sides of the equation gives us two solutions: x = 6 and x = -6.

Therefore, any statement claiming that there is only one solution is incorrect. The true statements would acknowledge the existence of two solutions, one positive and one negative.

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .

Number of tiles with picture of plants =7

Number of tiles with picture of animals =2

Total number of tiles =7+2=9

We have to find the probability that the second tile that Maggie turns over has  plant on it .

When she removes one tile of picture of plant then she has number of tiles of picture of plants =6

Total number of tiles =8

Probability,P(E)=[tex]\frac{Number\;of\;favorable\;cases}{Total\;number\;of\;cases}[/tex]

Using the formula then we get

The probability that she finds tile of picture of plant =[tex]\frac{6}{8}=\frac{3}{4}[/tex]

Answer:

$15,500

Step-by-step explanation:

Let s represent the initial salary.  That salary, plus a 5% raise, comes out to 1.05s = $16,275.

Solve for s by dividing both sides by 1.05:

s = $16,275 / 1.05 = $15,500.

The original salary was $15,500.

Final answer:

The original salary before a 5% raise resulting in a new salary of $16,275 was $15,500. We found this by dividing the new salary by 1.05.

Explanation:

The question asks us to determine an employee's original salary before a 5% raise. To solve this, we assume that the new salary ($16,275) is 105% of the original salary (100% + 5% raise). Therefore, we can set up the following equation: Original Salary × 1.05 = $16,275. Now, we want to find the Original Salary, so we divide $16,275 by 1.05.

Original Salary = $16,275 ÷ 1.05

When we divide $16,275 by 1.05, we get the Original Salary = $15,500.

Therefore, before the increase in pay, the employee's salary was $15,500.

First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225

so we subtract 225 from 900 and get 675 pounds.

to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50

675 + 40.50 = 715.5 pounds

Answer:

[tex]\large\boxed{y=6x+9}[/tex]

Step-by-step explanation:

The slope-intercept form of the equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

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

We have the points E(-1, 3) and F(-2, -3). Substitute:

[tex]m=\dfrac{-3-3}{-2-(-1)}=\dfrac{-6}{-2+1}=\dfrac{-6}{-1}=6[/tex]

Therefore the equation of a line is:

[tex]y=6x+b[/tex]

Put the coordinates of the point E(-1, 3) to the equation and solve it for b:

[tex]3=6(-1)+b[/tex]

[tex]3=-6+b[/tex]             add 6 to both sides

[tex]9=b\to b=9[/tex]

Finally we have:

[tex]y=6x+9[/tex]
