Answer:
1. 7x
2. x+15
3. 18/x
Step-by-step explanation:
Assume the number is x because we don’t know what it is.
1. Product means multiplication so x * 7 equals 7x.
2. More means addition so x+15.
3. This one is easy. 18 divided by x = 18/x

The American Academy Dermatology says that hair grows about 6 inches per year. How much hair can you expect to grow after 3 years, given that you do not get any haircuts.
Answers
If hair grows about 6 inches every year, and we want to find out how much will grow in 3 years, we multiply.
6 x 3 = 18 inches
Then we can simplify it because there are 12 inches in a foot
18/12 = 1 6/12

If my function rule is 2x + 1, what is the OUTPUT if the input is 2?
Answers
Work Shown:
x = 2 is the input
y = 2x+1
y = 2(2)+1
y = 4+1
y = 5 is the output
A function is a relationship between inputs where each input is related to exactly one output.
The value of the output of function 2x + 1 when x =2 is 5.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
1.
f(x) = 3x + 2
x = 1,
f(1) = 3x1 + 2 = 3 + 2 = 5
Input = 1
Output = 5
2.
g(x) = 4x + 2
For x = 1, g(1) = 4x1 + 2 = 4 + 2 = 6
Input = 1
Output = 6
We have,
Function:
2x + 1
Input = 2
The value of the output of the function 2x + 1 when x =2:
= 2x + 1
= 2x2 + 1
= 4 + 1
= 5
Thus,
The value of the output of function 2x + 1 when x =2 is 5.

Answers
Answer: 24100
Step-by-step explanation:
The money in the account after 8 years is $24068.631.
Given that, principal=$19000 and the rate of interest=3%.
What is the formula to find the compound interest?The formula to find the compound interest is CI=A-P.
Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.
Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]
=19000[tex](1.03)^{8}[/tex]
=19000×1.26677008139
=$24068.6315464
=$24068.631
Therefore, the money in account is $24068.631.

To boil rice, start by combining water and rice in a pot at a ratio of 3:1. How many cups of water are need for a batch that uses eight cups of rice?
Answers
Answer:
Step-by-step explanation:
To boil rice you use the following ratio
Water : Rice
3 : 1
? : 8
Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.
6 cups of water, you need 2 cups of rice (6:2)
9 cups of water, 3 cups of rice (9:3)
Etc.
All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)
Answer:
ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24

What is the slope of a line perpendicular to the line whose equation is
2x+12y=−192. Fully reduce your answer.
Answers
Mperpendicular=6
Pls mark me brainliest
The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.
First, we have to find the slope of the given line
The equation of the line which is given as
2x + 12y = −192
12y = −192 - 2x
Divided by 12 both sides of the above equation to get the slope-intercept form
y = - (1/6)x - 16
Here the slope of the line (m) = -1/6
So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.

a = admission cost
b/c) 1.25(25)+a=43.75

43.75-31.25=12.50 cost of admission
12.50+31.25=43.75 total cost at the country fair.
