The construction cost for the concrete base is estimated at $20 per square foot. Again, if r is the radius of the cylinder, what would be the area of the circular base? Note that the base must have a radius that is 1 foot larger than that of the cylinder. Write an expression for the estimated cost of the base.

A student has a container with a volume of 0.5 liter. He estimates the volume to be 0.4 liter. By what percent is the student's estimate off?
Answers
Answer:
20

What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that a student has a container with a volume of 0.5 liter.
He estimates the volume to be 0.4 liter.
Now to find the percentage of estimation,
estimated volume = correct volume × required percentage / 100
0.4 = 0.5 × required percentage / 100
Required percentage = 0.4 × 100 / 0.5
Required percentage = 0.4 × 100 / 0.5
Required percentage = 80%
Therefore, the students's estimation is 80%.

Step-by-step explanation:
Answer: No
Step-by-step explanation:
X = 3
Replace the variable X with 3
4 x 3 - 3 (less than or equal to) 5

HELP ILY A tree is 4 1/2 feet tall. It is expected to grow by 1 3/4
feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet? Enter the answer in the box.
years
Answers
Answer:
It will take 21 years.
Step-by-step explanation:
First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.
4.5 + 1.75x = 40
Subtract 4.5 from both sides. This cancels out the +4.5.
1.75x = 40 - 4.5
Subtract 4.5 from 40 to get 35.5.
1.75x = 35.5
Divide both sides by 1.75. This cancels out the *1.75.
x = 35.5/1.75
Expand 35.5/1.75 by multiply both the numerator and denominator by 100.
x = 3550/175
Reduce 3550/175 by canceling out 25.
x = 142/7 = 20 2/7
Go up by one from 20 to get the answer of 21 years.

Are 5x and 5x^2 like terms? Explain your answerc
Answers
Answer:
No. 5x and 5x² are not like terms.
When a variable is raised to two different powers, they can not be added together.
Another way to look at it is to note that:
5x + 5x² ≡ 5x(1 + x)
It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.
