The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal.
In 4 days, Val walks
4*(2 3/5) miles
4*(13/5) miles 52/5 miles
10 2/5 miles
Compare that to Bill, who runs 10 miles every 4 days.
Answer:
x=-7, -5
Step-by-step explanation:
x^2+12x+35=0
(X+5)(X+7)=0
x=-7, -5
Answer:
4.756 miles
Step-by-step explanation:
It is given that,
The running trail in the local park is 3.416 miles long. If the park board were planning to extend the trail by 1.34 miles.
We need to find the new length of the running trial. It is equal to the sum of length of running trail and the extended length. So,
l = 3.416 +1.34
l = 4.756 miles
So, the new length of the running trail be 4.756 miles
Answer:
The best estimate is greater than 1/2 but less than 3/4
Step-by-step explanation:
If you multiply 1/4 by 3/3 (which is also 1), you can change the denominator without changing the value. So 1/4 is equal to 3/12.
Since keith has 11/12 hours to play, and he has already played 3/12 hours, subtract 3/12 from 11/12 to get 8/12 hours. This is how much time he has left to play.
If you simplify 8/12 hours, you get 2/3 hours.
So the best estimate would be: greater than 1/2 but less than 3/4.
Cylinder:
V = pi * r^2 * h
V = 3.14 * 9^2 * 11
Simplify exponent:
V = 3.14 * 81 * 11
Multiply:
V = 2797.74
Sphere:
V = 4/3 * pi * r^3
V = 4/3 * 3.14 * 9^3
Simplify exponent:
V = 4/3 * 3.14 * 729
Multiply:
V = 3052.08
Cone:
V = 1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 12^2 * 20
Simplify exponent:
V = 1/3 * 3.14 * 144 * 20
Multiply:
V = 3014.4
So the Sphere holds the most.
