Answer:
21.9
Step-by-step explanation:
circumference = pi x diameter
3.14 x 7 = 21.9
Answer:
2x
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = 
· · 
This can be simplified to be 2x
Answer: A. Ounces of water consumed compared with the number of same-size bottles drunk
Step-by-step explanation:
When a quantity changes uniformly with respect to the change of other quantity, then we say there is a constant rate of change.
Thus, if one quantity is directly proportional to the other quantity then there is constant rate of change.
A. Ounces of water consumed is directly proportional to the number of same-size bottles drunk. Hence there is a constant rate of change of ounces water with respect to the number of same-sized bottles.
Rest of other options do not have directly proportionality relation between the quantities.
Answer:
Step-by-step explanation:
You are given the equation for the number of times, y, that she visits them by distance x. You need only substitute the given x=4 into the equation y(x)
y=-3.5x+20, using x=4
y=-3.5(4)+20
y=-14+20
y=6
So we would expect her to visit her friend four miles away six times a month.
