Use the area of the rectangle to find the area of the triangle
Alborosie
Answer is D

if you want to get the area of a triangle you have to multiply the base times height and than divide by 2

A= 1/2 bh
A=1/2 (7x6)
A= 1/2(42)
A= 21

and for the area of the rectangle it’s 42 since there’s no dividing

A=bh
A=7x6
A=42

A single tennis court is 75% the width of a doubles tennis court. The singles court is 27 feet wide. How wide is the doubles cou
grandymaker [24]
X = 75% * y

Where 'x' is the single tennis court width, and 'y' is the doubles tennis court width.

Plug in what we know:

27 = 75% * y

75% = 0.75

27 = 0.75 * y

27 = 0.75y

Divide 0.75 to both sides:

y = 36

So the doubles court is 36 feet wide.

Hello everyone I need help with this worksheet it's ten problems answer the ones you know for me please it's homework.
Fed [463]

Answer:

1. Slope = -4/5

2. Slope = 2/3

3. Slope = 0

4. Slope = 3/-4

5. Slope = 7/-12

6. Slope = 1/2

7. Slope = -2/0 --> Undefined

8. Slope = 3/-2

9. Slope = 5/-4

10. Slope = 4/3

Step-by-step explanation:

Ok so I'm assuming that you want the slope for all the two points. Basically, the formula for slope is rise/run, or y2-y1/x2-x1. Solve using that. For example, for number 1, it would be:

10-2/1-11 = 8/-10 = -4/5
