Answer: 
Step-by-step explanation:
1. If you join the top part and the bottom part of the figure, you obtain a sphere. Then, you must apply the formula for calculate the surface area of a sphere:
Where r is the radius (
)
2. Then:
3. The formula for calculate the suface area of the red part, which is a cylinder, is:
Where h is the height (h=32mm)
4. Then:
5. So, the total surface area is:
<span>all real numbers less than or equal to 7</span>
<u>Answer:</u>
A. (x+5)
<u>Step-by-step explanation:</u>
We are given a quadratic expression 
which we will factorize to see which of the given options is a binomial factor of it.
Finding the factors of 15 such that when added, they give a result of 8.
Therefore, we can see that 
is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
You can get the different results for the same equation if one of the results is a variable. This is because, in this problem, x=12.
Answer:
y= 500+7x
Step-by-step explanation:
Given data
Total amount for the rent= $500
Cost of food per night= $10
Family charges per night=$60
Let the number of nights be x
and let the total charges be y
Hence, the expression for the situation is given as
y=500+10x+60x
y= 500+7x
