First do 10x7 =70
Since there’s 4 sides with this measure mentally do 70x8=560
560
10x8.7=87
87+560=647
647sq feet
Answer:
$11.25
Step-by-step explanation:
5 bags = $18.75
To find the amount for three bags, we need to find the price for <em>each </em>bag.
Divide 18.75 by 5.
18.75/5 = 3.75
So each bag is 3.75, and since we need to know the price for 3 bags, we need to multiply 3.75 by 3, which is 11.25.
Answer:
A = 4 in^2
Step-by-step explanation:
The area is given by
A = l*w
A = 1in * 4 in
A = 4 in^2
Answer:
Diameter = 9
Step-by-step explanation:
Let the diameter be represented as x.
Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
(16 + x)(16) = 20²
256 + 16x = 400
Subtract 256 from each side
16x = 400 - 256
16x = 144
Divide both sides by 16
x = 144/16
x = 9
Diameter = 9
