Answer:

21 dollars

Step-by-step explanation:

Answer:

$21

Step-by-step explanation:

Make the original statement into a ratio.

$28/4

Simplify the fraction above.

$28/4 = 7

So, you earn $7 per car you wash.

As a result, you multiply $7 by the number of cars the question is asking you for. In this case it is 3 cars.

So, you multiply 7 x 3

7 x 3 = 21

Therefore, you will earn $21 for washing 3 cars.

Answer:

log 4 ( 4096 )  = 6

Step-by-step explanation:

Convert the exponential equation to a logarithmic equation using the logarithm base  ( 4 )  of the right side  ( 4096 )  equals the exponent  ( 6 )

Answer:

[tex]y = 1/3x-2[/tex]

Step-by-step explanation:

General line equation:

[tex]\frac{y-y_{1}}{x-x_{1}} = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

Or

[tex]y = a.x + b\\a = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\b = y_{1} - a.x_{1}[/tex]

where a is the slope and b is vertical displacement.

For a line to be parallel to another, they both have to have the same slope, therefor, the parallel line's slope is 1/3.

By substituting the given point and a = 1/3 in above equation for b, b is equal to -2. Therefore,

[tex]y = 1/3x - 2[/tex]

Answer:

1. 2

2. 3

3. 35

4. 3

5. m=79

Answer:

160

Step-by-step explanation:

Answer:

B. 135, 45, 15, 5...

Step-by-step explanation:

I'll go in order from 135 using the pattern shown (tᵇ/3)

135 / 3

135 = 120 + 15

135/3 = (120/3) + (15/3)

135/3 = 40 + 5

135/3 = 45

All four answer choices show this, so no elimination yet.

45 / 3

45 = 30 + 15

45/3 = (30/3) + (15/3)

45/3 = 10 + 5

45/3 = 15

A and D show 30 as term 3, so they are out.

15 / 3

15/3 = 5

C shows 2 as term 4, so that is also out.

This leaves B as the correct answer.

Answer:

[tex]x = 11[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find x

The theorem that applies to this question is the theorem of external angles. And it translates to:

[tex]11x +2 = 58 + 5x + 10[/tex]

Collect Like Terms

[tex]11x -5x = 58 + 10-2[/tex]

[tex]11x -5x = 66[/tex]

[tex]6x = 66[/tex]

Divide through by 6

[tex]\frac{6x}{6} = \frac{66}{6}[/tex]

[tex]x = \frac{66}{6}[/tex]

[tex]x = 11[/tex]

Answer:  20, 70, 90

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

Work Shown:

Let x be some positive real number.

Multiply each part of the given ratio by x to get 2x:7x:9x

So we have the three angles 2x, 7x, and 9x.

For any triangle, the three angles must add to 180

2x+7x+9x = 180

18x = 180

x = 180/18

x = 10

This leads to

The three angles of this triangle are: 20, 70, 90

This is a right triangle due to the 90 degree angle.

Answer:

6.75 or 6and 3/4

Step-by-step explanation:

-2x - (-18x + 126) = -18

-2x + 18x - 126 = -18

16x = -18 + 126

16x = 108

x = 6.75 OR 6 3/4

Answer:

sorry it's too late my friend

Hi, this expression is not solvable because we can just literally substitute anything with x. You cannot solve an expression, unless given a value. However,  you can solve an equation. In this case, it is an expression.

Answer:

127.253 m^3

Step-by-step explanation:

To find the volume, we start by getting the area of the square base

Mathematically, that will be 4.9^2 m^2

To complete the volume, we multiply the area of the base by the height

= 4.9^2 * 5.3 = 127.253 m^3
