If a rectangle has an area of 132 Units and a length of 11 units what is the width? If necessary round your answer to decimal pl

Rus_ich [418]

Answer: 12.00 units

An area should be measured in square units so the area in the question should be 132 square units. In a rectangle having an area of 132 square units and a length of 11 units, the width (W) is computed as follows:

W=A/L

W=132/11

12.00 units

What is the equation of the following line? Be sure to scroll down first to see

Advocard [28]

Question:

What is the equation of the following line? Be sure to scroll down first to see all answer options. ( 0, 0) (2, -8)

Answer:

The equation of line is y = -4x

Solution:

Given points are ( 0, 0) (2, -8)

Find the slope of line

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

From given,

$(x_1, y_1) = (0, 0)\\\\(x_2, y_2) = (2, -8)$

Substituting the values we get,

$m = \frac{-8-0}{2-0}\\\\m = -4$

The equation of line in slope intercept form is given as:

y = mx + c --------- eqn 1

Where,

m is the slope of line

c is the y intercept

Substitute m = -4 and (x, y) = (0, 0) in eqn 1

0 = -4(0) + c

c = 0

Substitute m = -4 and c = 0 in eqn 1

y = -4x + 0

y = -4x

Thus the equation of line is y = -4x

Karolina [17]

Answer:

120

Step-by-step explanation:

If Sylvia can choose one of each class, then there are 4 ways she can choose the math class, 2 ways to choose the science class, 3 ways to choose the language class, and 5 ways to choose the art class.

Multiplying these, 4*2*3*5 = 120
