Answer:
9.55 minutes
Step-by-step explanation:
x hours to go to the river
0.25-x hours to come back, since 15 minutes is 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
those two are equal
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes
Answer:
The area of the parallelogram is 
Step-by-step explanation:
Remember that a mixed fractions are composed for a whole number, a numerator and a denominator. For example in the mixed fraction 
: 2 is the whole number, 1 is the numerator and 3 is the denominator.
If you want to convert to a improper fraction you need to multiply the whole number by the denominator and add to the numerator. The result will be the numerator of the improper fraction. The denominator remains the same.
1. Convert the mixed fractions in the improper fraction type, as follows:
2. Replace the data in the equation of a parallelogram
3. Convert the improper fraction in a mixed fraction
The area of the parallelogram is
Given:
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70
This is the answer hope it helps you
