22.7%
Step-by-step explanation:
Answer:
245.04
Step-by-step explanation:
The equation to a cylinder for area is A=2πrh+2πr^2
Fill in and solve.
A=2(3.14)(3)(10)+2(3.14)(3)^2
So using PEMDAS you get the answer 245.04
Solution:
Let's name the three consecutive numbers as y, y + 2, and y + 4.
<u>Note that:</u>
- => Equation formed: 3(y) = 2(y + 4)
<u>Solve the equation to find the three consecutive numbers.</u>
- 3(y) = 2(y + 4)
- => 3y = 2y + 8
- => 3y - 2y = 8
- => y = 8
The numbers are 8, 10, and 12.
Answer:
The value after 7 years is $ 855355.65
Solution:
Given that, Annual sales for a fast food restaurant are 650000 and are increasing at a rate of 4% per year
To find: exponential function to find the annual sales after 7 years
The exponential growth function is given as:
Where,
"a" is the initial amount
"y" is the future value
"r" is the rate of interest in decimal
"t" is the number of years
Here in this given question,
a = 650000
t = 7 years
Substituting the values in given formula,
Thus the value after 7 years is $ 855355.65
Step-by-step explanation:
The surface area is given by:
A = 4πr ^ 2
Where,
r: sphere radio
Substituting values we have:
2700 = 4 (3) r ^ 2
Clearing r we have:
r = root (2700/12)
r = 15
Then, the volume of the sphere is given by:
V = (4/3) πr ^ 3
Substituting values:
V = (4/3) * (3) * (15) ^ 3
V = 13500 cm ^ 3
Answer:
The approximate volume of the globe is:
V = 13500 cm ^ 3
