Answer:
Step-by-step explanation:
1. First, you must calculate the area of the football field. It is a rectangle, therefore, multiply the lenght by the width to calculate the area:
2. Then, divide this area by the area covered by a wheelbarrow full of dirt.
: number of wheelbarrows full of dirt needed for the field.
3 Is B. The formula for finding the area of a circle is A= r(to the second power) times Pi. The radius is 6, so you must do 6 to the second power which is 6 times 6. That is 36. Your answer will be 36 pi.
Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
Answer:
2x+6
Step-by-step explanation:
Distribute 2 to the x and get 3x, and distribute 2 to the 3 and get 2
