Keith bought a bottled water for 4 dollars and 7 power bars. he spent a total of $32.00. what was the cost of a power bar?

A power bar costs $4

Step-by-step explanation:

First, subtract the amount Keith spent on the bottled water ($4.00) from the total ($32.00):

32 - 4 = 28.

Next, divide 28 by 7 to get the cost of a power bar.

28 ÷ 7 = 4

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
