Answer:
275 m/s2
Step-by-step explanation:
I know because I had this question in a test and got it correct.
Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:
Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.
Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.
The red car can travel farther on 1 gallon of gas.
The total length of the border = 50.2 yards
Step-by-step explanation:
Step 1 :
Given,
Diameter of the circular region = 16 yards
We need to compute the total length of the border.
Step 2 :
The total length of the border can be obtained by computing circumference of the region with the given diameter
Circumference = 2(pi)(r)
where r is the radius
here diameter = 16, so radius = 8 yards
Hence circumference = 2 (3.14) 8 = 50.24 yards
Step 3 :
Answer :
The total length of given border = 50.2 yards (rounded off to nearest 10th)
