Answer:

$\frac{-2-r}{-p+8}$ .

Step-by-step explanation:

-px+r= -8x-2

-px+8x = -2-r

x(-p+8) = -2-r

x = $\frac{-2-r}{-p+8}$ .

Answer:

1. Draw out a diagram as a triangle with one side as the 5' rise, the other side as the horizontal run, and the hypotenuse as the ramp.

2. Put the 5 ° in as the angle between the run and the ramp.

3. Let the run = x. Using trigonometry (needed!) the tangent angle (tan) of 5° = opposite/adjacent = 5/x.

4. So x = 5/tan(5°). you will need a scientific calculator to solve.

Log_7 10 Approximate to four decimal places

Alenkinab [10]

Answer:

1.1833 to 4 places of decimals.

Step-by-step explanation:

The general formula for change of base is

log_a x = log_b x / log_b a

log_7 10 = log_10 10 / log_10 7

= 1/ 0.845098

= 1.1833.

Answer:

Question 1:

Draw a line that crosses the largest number of dots. Then use the line to check the best prediction of the number of baseballs that will be used if 275 pitches are thrown.

Question 2:

A). y = 1.2x - 6

Question 3:

J). y = $\frac{9}{4}x - 81$

Question 4:

F). f(n) = -3n + 24 *Although it doesn't work when f(n) = 6 and n = 6*

Step-by-step explanation:

Question 2:

The line passes throught point (5, 0) and is parallel to the line whose equation is y = 1.2x + 3.8

For parallel lines, their values of slope is the same.

So our line, that passes through point (5, 0), also has a slope of 1.2

Taking another point (x, y) on our line;

Slope = change in y ÷ change in x

1.2 = $\frac{y - 0}{x - 5}$

y = 1.2x - 1.2(5)

y = 1.2x - 6

Question 3:

The line passes x-axis at point (36, 0)

The line is perpendicular to another line whose equation is y = - $\frac{4}{9}x$ + 5

For perpendicular lines, the product of their slopes = -1

Let's say the slope of our unknown line is a ;

Given: The slope of our second line is -4/9

So,

a × -4/9 = -1

a = -1 × -9/4 = 9/4

Taking another point (x, y) on our unknown line;

Slope = change in y ÷ change in x

9/4 = $\frac{y - 0}{x - 36}$

Cross-multiplying that you get;

y = $\frac{9}{4}x - 81$

Question 4:

The function that model that situation is f(n) = -3n + 24 though it doesn't work when f(n) = 6 and n = 6

Would you rather 36 spherical bottles with radi = 4.57 or three 12-packs of cans if each box is 15inx5inx4.4in

grigory [225]

Answer:

36 bottles

Step-by-step explanation:

Each spherical bottle will have a volume of ...

V = (4/3)πr³ = (4/3)π(4.57³) = 399.8 . . . . cubic inches

Each box (12-pack?) will have a volume of ...

V = LWH = (15 in)(5 in)(4.4 in) = 330 in³

This is a smaller volume than even one spherical bottle, so 36 bottles will have the larger volume.
