Mandy is making a rectangular quilt. She created a scale drawing of the quilt using a scale of 1 cm = 7.5 in. The quilt on the d
rawing measures 8 cm by 12 cm. What is the area of the actual quilt?
1 answer:
Answer:
Actual Area=5,400 (in.)²
Step-by-step explanation:
Scale: 1 cm=7.5 in.
Drawing is 8 cm by 12 cm
Drawing Length=12 cm
Actual Length=Scale factor×Drawing Length=(7.5×12)=90 in.
Drawing Width=8 cm
Actual Width=Scale factor×Drawing Length=(7.5×8)=60 in.
Actual Area=(Actual Length×Actual width)=(90×60)=5,400 squared inches
Actual Area=5,400 (in.)²

Answer:
The slope is 0.
Step-by-step explanation:
m= (y2-y1)/(x2-x1).
y2 is -3, y1 is -3.
x2 is 1 and x1 is -9.
m= -3 -(-3)/ 1- (-9)
m= 0/10
m=0
A = pi(r)^2
diameter is 18in, so radius is 9in
= pi(9)^2
A = 254.469 (round is needed)
The answer is 1/3 because of rise over run
3.right angle
4. Right angle
