Answer:

360 feet

Step-by-step explanation:

Given function:

7.2 feet, 4 feet, 12.5 feet
L·W

Multiply all terms:

$7.2$ · $4$ · $12.5= 360$

Therefore, the volune of the rectangular prisms would be 360 feet..

The angle measures are represented by algebraic expressions.

Anuta_ua [19.1K]

Answer:

The value of x is 0.5

The value of y is 0.8

The value of z is 0.9

Step-by-step explanation:

* Lets explain how to find the values of x , y and z

- From the attached figure

# $l_{1}$ and $l_{2}$ intersect each other at a point

- When two lines intersect each other at a point they formed

congruent vertical opposite angles

∴ The angle of measure (50z + 13)° = the angle of measure (80z - 14)°

because thy are vertical opposite angles

∴ 50z + 13 = 80z - 14

- Add 14 to both sides

∴ 50z + 27 = 80z

- Subtract 50z from both sides

∴ 27 = 30z

- Divide both sides by 30

∴ $z=\frac{27}{30}=\frac{9}{10}=0.9$

* The value of z is 0.9

- From the attached figure

# The angles of measures (50z + 13)° and (45x + 19/2)° have sum

of 90°

∴ 50z + 13 + 45x + 19/2 = 90

∵ z = 0.9

∴ 50(0.9) + 13 + 45x + 19/2 = 90

∴ 45 + 13 + 45x + 9.5 = 90

- Add like term in the left hand side

∴ 67.5 + 45x = 90

- Subtract 67.5 from both sides

∴ 45x = 22.5

- Divide both sides by 45

∴ x = 0.5

* The value of x is 0.5

- From the attached figure

# There is a ray perpendicular to line $l_{1}$

∴ The measure of the angle whose measure (225y/2)° is 90°

∴ $\frac{225y}{2}=90$

- Multiply both sides by 2

∴ 225y = 180

- Divide both sides by 225

∴ $y=\frac{180}{225}=\frac{4}{5}=0.8$

* The value of y is 0.8

Independent variables are variables of a quantity that are not affected by any conditions.

Dependent variables are variables of a quantity that change if conditions relative to that variable changes.

For example, we generally we take x as independent variable by x variable and dependent variable by y variable.

To find the rate of change we get two values of independent variable (x's) and two values of dependent variables (y's) to get two coordinates in form of

(x,1,y1) and (x2,y2).

<h3>And we can find the rate of change by applying slope formula</h3>

$m= \frac{y_2-y_1}{x_2-x_1}$ .

bagirrra123 [75]

Hi!

We can set up a proportion then cross multiply to solve this.

$\frac{45}{x} \frac{18}{100}$

45 x 100 = 4500
4500/18 = 250

The answer is 250

Hope this helps! :)
