Answer:
20/25
Step-by-step explanation:
divide the denominators
25/5=5
multiply the numerator
4*5=20
Answer:
1.35kg
Step-by-step explanation:
450g : 6 people
x : 18 people
To get from 6 to 18, multiply by 3 so do the same to the other side
450 × 3 = 1350g
To convert from g to kg divide by 1000
1350 ÷ 1000 = 1.35kg
i think C but i dont know forsure
The function rule for x is +1. When you want to get the next number in the set, you add one to the previous number. For example, -1 + 1 = 0.
The function rule for y is - 5. When you want to get the next number in the set, you subtract five to the previous number. For example, 9 - 5 = 4.
Hope this helps!
Answer:
0.00636 ft/min
Step-by-step explanation:
considering 'r' as radius of base at time t
'h' as height at time t
V = volume of cone at time t
Given: dV/dt = 10 ft³/min
Find: dh/dt when h = 17 ft
As we know that equation of volume is defined as
V = (1/3)πr²h
[The diameter of the base of the cone is approximately three times the altitude.therefore, 2r = 3h, r = (3/2)h ]
V = (1/3)π[(3/2)h]2h
= (3/4)πh³
= ()πh²()
13 = () π (17)²(dh/dt)
= 
=
= 0.00636 ft/min
therefore, the pile is changing at the rate of 0.00636 ft/min
