Let's make W = width, and L = length.
What do we know? We know that P = 40 yards, and L = W + 1.5 .
The formulas for perimeter and area are:
P = 2W+2L
A = W*L
We can set P to 40, and since L = W+1.5, we can substitute that in for L.
40 = 2W + 2 (W+1.5)
40 = 2W + 2W + 3
37 = 4W
W = 37/4
We can plug that into L to find the length.
L = W + 1.5
L = 37/4 + 3/2
L = 43/4
Now, we plug into the area formula!
A = L*W
A = 43/4 * 37/4
A = 1591/16 or 99.43 yd^2
Answer:
1
3
5
Step-by-step explanation:
Plug the X value into the given equation
(-2) + 3 = 1
(0) + 3 = 3
(2) + 3 = 5
Answer:
0.95 miles per minute
19 miles in 20 minutes
Step-by-step explanation:
To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).
Answer:
18.8cm
Step-by-step explanation:
Multiply 3 by pi.
You get 9.42
Multiply that by 2.
You get 18.84.
Because the perimiter is also known as the circumference and the formula for that is 2rπ
