If d=rt and r=3mph and t=7hrs the equation is d=3*7. to find d multiply 3 by 7 to get 21. d=21mi
Answer:
I'm pretty sure she needs to have $18.45
Step-by-step explanation:
All you have to do is add the numbers together to get the minimum amount
Answer:
Perimeter = 21 units
Volume = 110 cubic units
Step-by-step explanation:
Let the center of circle be (x,y).
4x - 18y = - 45
4x + 8y = 4
x + 2y = 1
Solving these 2 equations,
4 - 26y = -45
y =
x =
radius = 3.35
Perimeter = 2 = 21 units
Volume of cylinder =
We have to add the volumes of the cylinders.
Volume of smaller cylinder = = 8
Volume of larger cylinder = 27
Total volume = 35 = 110 cubic feet
Step-by-step explanation:
C=2×pi×r
8.61=2pi*×r
8.61÷2pi=13.52 radius
A=pi×r^2
pi×13.52^2=574.25 area
Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
