Answer: 28 years
Step-by-step explanation:
Given
The equation showing the value of the bag after x years is 
If the price of the bag increased by 2.5%, from the equation, we can deduce that
Initial cost of the bag is 25
Double of the initial value is 50
Insert it in the equation
It will take 28 years
Answer:
2x^2+x+6
Step-by-step explanation:
if the 4x3 meant 4x^3, then im pretty sure this is the correct answer
The answer is
y= - x-9/3 I believe.
1- Subtract 9 from both sides.
-3y = x - 9
2- Divide both sides by -3
y = - x-9/3
Answer:
19.6
Step-by-step explanation:
21+3=24
24-7.20=16.8
4+2=6
6-8.80=-2.8
19.6
Answer:
654 1/2 cm³
Step-by-step explanation:
First the volume of the cylinder, the formula for that is πr²h
Radius is half of diameter so 7/2=3.5
3.5^2=12.25
12.25x22/7=38.5
38.5x15=577.5
Now the cone, the formula for this is πr²h/3
It has the same radius as the cylinder so 3.5^2=12.25
12.25x22/7=38.5
38.5x6=231
231/3=77
Now we add them together to find total volume.
577.5+77=654.5
