Tell whether the angles are adjacent or vertical. Then find the value of x.

Answer:

x = -1

y = 1

Step-by-step explanation:

Since it gives you "y", plug in the number given into the equation:

y = -6x - 5

1 = -6x - 5

Then, add 5 to both sides:

1 = -6x - 5

+5       + 5

________

6 = -6x

Divide both sides by -6:

6 = -6x

-1 = x

So now you have, x = -1 and y = 1

Step-by-step explanation:

As x and y are perpendicular - we can use pythagoras.

So, The length of side x squared + The length of side y squared = The missing length squared.

12^2=144

5^2=25

144+25=169

sqrt169=13

Answer:

Unknown side = 13 in

Step-by-step explanation:

If it is a right sided triangle, then you can use the Pythagoras theoreum.

unknown side = u

x² + y² = u²

12² + 5² = u²

u² = 144 + 25

u² = 169

u = + - SQRT(169)

{Only the positive value has a meaning}.

Unknown side = 13 in

Answer:

j - 10 = 35

j = 45

Step-by-step explanation:

When it says, "less than" it means subtracting. So 10 less than j is (j - 10)

The part where is says "is" means it is equal to.

So the equation would be = (j - 10) = 35

Answer:

Equation: (j - 10) = 35

j = 45

Step-by-step explanation: Lets translate 10 less than j:

Less than means 10 is being subtracted from j.

So we can write 10 less than j as j - 10.

The word is means equal.

So, we can write is 35 as = 35.

Now lets write the whole equation toghter.

j - 10 = 35

We can also write this as 35 = j - 10.

Now we can solve for j.

Add 10 to both sides of the equation to get j by itself.

j - 10 + 10 = 35 + 10

J=45

The following equation matches this situation:

j - 10 = 35

j = 45

Answer:

13 boxes

Step-by-step explanation:

To calculate the minimum number of boxes that can be had with that amount of paper, they should be kept in the largest box, that is, the 27 cubic foot box, therefore, we divide:

257/27 = 9.51

Which means that we can save the paper in 9 boxes of 27 cubic feet, now we will save the rest in the next smaller box, the 9 cubic foot box.

First let's calculate how many leftover paper:

257 - 27 * 9 = 14

Therefore, we can only use 1 box of 9 cubic feet:

14 - 9 = 5

For the remaining 5 cubic feet use 1 box of 3 cubic feet and 2 boxes of 1 cubic foot.

Therefore, in total it would be:

9 of 27 ft ^ 3 + 1 of 9 ft ^ 3 + 1 of 3 ft ^ 3 + 2 of 1 ft ^ 3 = 13

a total of 13 boxes would be the minimum

gradient = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

Given

- 2x + y - 5 = 0 ( add 2x and 5 to both sides )

y = 2x + 5 ← in slope- intercept form

with gradient m = 2

Parallel lines have equal gradients

Step-by-step explanation:

The question isn't clear enough. However, I'll solve for the total number of students in science class and I'll.also solve for the total number of students present in class.

Given

Proportion of girls = ⅓

Number of girls absent = 3

Number of girls present = 4

Required

Find the total number of students

If 3 girls were absent and 4 were present, then there are total of 7 girls in science class.

Let the number of students in the class be represented by y.

⅓ of the total number of students are girls;

This means

⅓ of y = 7

⅓ * y = 7

Multiply both sides by 3

3 * ⅓ * y = 3 * 7

y = 3 * 7

y = 21.

Hence, the total number of students in science class is 21

Recall that 3 girls are absent;

This means that 21 - 3 are presently in the class.

21 - 3 = 18.

Hence, 18 students are presently in class.

Answer:

3000+4500= 7500

Answer: A

Step-by-step explanation:

The first square is 22 inches on a side.

The second is 17.6 inches on a side

the third is 14.08 inches on a side.

We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:

22in*x = 17.6in

where x is the rate of scale.

x = 17.6/22 = 0.8

Now we test this with the second and third:

17.6in*0.8  = 14.08in

Ok, this works.

then the side of n-th cube can be found with the equation

L = 22*0.8^(n-1)

we can try the different options and see which one gives a value smaller than 10.

A) n = 5

L = 22*0.8^4 = 9.01

Then the correct option is A

For example, the first one is -1/3. It's slope is going down to the right, so it's negative . It goes down 1 (y value) and over to the right 3 (x value). Since it goes down and to the right it is a slope of -1/3.

The value of [tex]\(\log 12\)[/tex] is approximately 1.0792 based on the given logarithmic values. Option B [tex]$\approx 1.0791$[/tex]

Let's evaluate the logarithmic expression [tex]\(\log 12\)[/tex]. We'll use the given logarithmic values:

1. Recall that [tex]\(\log 12\)[/tex] represents the common logarithm (base 10 logarithm) of the number 12.

2. Apply the change of base formula:

  [tex]\[ \log 12 = \frac{\log 12}{\log 10} \][/tex]

Given values:

[tex]- \(\log 12 \approx 2.4849\) (from \(\log 12\))[/tex]

[tex]- \(\log 10 \approx 2.3026\) (from \(\log 10\))[/tex]

Now calculate:

[tex]\[ \log 12 \approx \frac{2.4849}{2.3026} \][/tex]

[tex]\[ \log 12 \approx 1.0792 \][/tex]

Therefore, the value of [tex]\(\log 12\)[/tex] is approximately 1.0792.

The correct answer is b. [tex]\(\approx 1.0791\)[/tex].

The correct question is:

Use the laws of logarithms and the values given below to evaluate the logarithmic expression.

[tex]$$\begin{array}{ll}\log 7=0.8451 & \log 5=0.6990 \\\log 3=0.4771 & \log 2=0.3010\end{array}$$[/tex]

Transformations in geometry include translation, rotation, reflection, and dilation, which are used to change a figure's position, orientation, or size. The appropriate transformation to use depends on the changes observed between the purple pre-image and the white image in the problem.

In mathematics, specifically in geometry, we use transformations to move or change a figure in some way without altering its fundamental shape or size. The transformation of a pre-image onto an image can be achieved using transformations such as translation, rotation, reflection, or dilation.

To transform the purple pre-image onto the white image, firstly identify the type of transformation required. For instance, if the white image is the same size as the purple pre-image and only its position has changed, use translation. If the image is mirrored along a line, use reflection. If it's turned around a point, use rotation. If the image is an enlarged or reduced version of the original figure, use dilation.

Consequently, the precise steps depend on the type of transformation(s) required.

Based on the information given the amount of the initial investment is $8,361.

Let P represent the amount of the initial investment

Hence,

12855.94 = P(1 + .0431/12) ^12(10)

12,855.94=P(1+0.0035917)^120

12,855.94=P(1.0035917)^120

12,855.94=P(1.53760782)

P=12,855.94/1.53760782

P=$8,360.8

P=$8,361 (Approximately)

Answer:

the total value of the liquid in the container is $29.4

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

The volume of a cone is expressed as

V=1/3(πr²h)

Given data

Height h= 9 inches

Radius r= diameter/2= 2.5/2= 1.25in

Substituting we have

V= 1/3(3.14)*(1.25)²*9

V= 1/3*(3.14)*14.06

V= 44.156/3

V= 14.7in³

The volume of the cone is 14.7in³

Hence If 1 in³ of liquid costs $2

14.7in³ will cost $x

x= 14.7*2

x= $29.4

Step-by-step explanation:

W = 9 + L

WL = 252

L = 12

Answer:

l = 12

Step-by-step explanation:

Let l = length

width = l+9

The area of rectangle is

A = lw

A = l * (l+9)

252 = l^2 +9l

Subtract 252 from each side

0 = l^2 +9l -252

Factor

What 2 numbers multiply to -252 and add to 9

21*-12 = 252

21-12 = 9

0 = (l+21) (l-12)

Using the zero product property

l+21=0    l-12=0

l = -21     l = 12

We cannot have a negative length

l = 12
