Answer:
12.6 square feet
Step-by-step explanation:
So first we set it up:
18ft is 100% of the original
and the area of the copies are 70%
Copies: x
x/70 = 18/100
70(18) = 1260
1260/100 = 12.6
x = 12.6
Answer:
This is an algebraic expression
Step-by-step explanation:
U won't ever use t to mean multiplication u will use a . Or × or a letter next to a number to symbolise mutiplication
Answer:
7
Step-by-step explanation:
The tangent of the angle is
... tan(α) = ay/ax = -8.6/6.1
Then the angle (measured CCW from +x) is
... α = arctan(-86/61) ≈ 305°
Take the longer leg length as

Use the formular
∴ shorter leg = 32 - 8 = 24ft
longer leg = 32ft
hypotenuse = 32 + 8 = 40ft
