Answer:

C. c(t) = 5 + 15t

Step-by-step explanation:

She charges $15 per hour, so each hour (represented by "t") she earns 15 dollars. She also charges a $5 fee per germent. So she would get $5 plus 15 times however many hours she worked. So your answer would be c(t) = 5 + 15t.

Answer:

C. c(t) = 5 + 15t

Step-by-step explanation:

Well because the initial fee is $5, the answer must have the value of 5 without a variable next to it because this is the y-intercept.

(Only the slope will have the t next to it.)

Because $15 is charged <u>EACH HOUR</u> this would be the slope because there is a constant increase

Therefore c(t) = 5 + 15t

An open-top box with a square base is to have a volume of 4 cubic feet. Find the dimensions of the box (in ft) that can be made

Lemur [1.5K]

Answer:

The dimension of box= $2ft\times 2ft\times 1ft$

Step-by-step explanation:

We are given that

Volume of box=4 cubic feet

Let x be the side of square base and h be the height of box

Volume of box= $lbh=x^2h$

$4=x^2h$

$h=\frac{4}{x^2}$

Now, surface area of box,A= $x^2+4xh$

$A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}$

$\frac{dA}{dx}=2x-\frac{16}{x^2}$

$\frac{dA}{dx}=0$

$2x-\frac{16}{x^2}=0$

$2x=\frac{16}{x^2}$

$x^3=8$

$x=2$

$\frac{d^2A}{dx^2}=2+\frac{32}{x^3}$

Substitute x=2

$\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0$

Hence, the area of box is minimum at x=2

Therefore, side of square base,x=2 ft

Height of box,h= $\frac{4}{2^2}=1 ft$

Hence, the dimension of box= $2ft\times 2ft\times 1ft$

Item 20 An online T-shirt store is having a sale. The original price of each T-shirt is p dollars. The store sells 20 T-shirts a

Bumek [7]

discount per tshirt=(originalprice-discountedprice)/numberofshirtssold

20 tshirts

originaprice=20*p=20p

discountedprice=20p-60

numberofshirtssold=20

discountpershirt=(20p-(20p-60))/20

discountpershirt=(20p-20p+60)/20

discountpershirt=(60)/20

discountpershirt=3

the discount per tshirt is $3.00 per shirt

Five less than nine times a number is the same as nineteen more than the number

Xelga [282]

Answer:

Step-by-step explanation:

The first thing you need to do is develop the equation. Less in this case means subtract.

On the left side you have

9 times a number which is 9*x

5 less than 9 times a number means 9x - 5

Now you shift to the right

x = 3

x + 19 What you get is

9x - 5 = x + 19 Subtract x from both sides of the equation

9x - x - 5 = 19 Combine both x terms on the left

8x - 5 = 19 Add 5 to both sides.

8x - 5 + 5 = 19 + 5 Combine terms

8x = 24 Divide by 8

x = 24/8

x = 3
