Suppose that 12 inches of wire cost 48 cents at the same rate how many inches of wire can be bought for 28 cents

goldenfox [79]

Answer:

7 in

Step-by-step explanation:

If 12 inches of wire can be bought for $0.48, we can set up the following ratio:

$\frac{12\text{ in}}{\$0.48}$

Then, to determine how many inches of wire can be bought for $0.28, set up equivalent fractions, as such:

$\frac{12\text{ in}}{\$0.48}=\frac{x}{\$0.28}$

Then, cross-multiply and solve for $x$ :

$\$0.48x=(\$0.28)(12)$

$\$0.48x=\$3.36$

$x=\frac{\$3.36}{\$0.48}$

$x=7$

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ

kumpel [21]

Answer:

side of 6.124 ft and height of 3.674 ft

Step-by-step explanation:

Let's s be the side of the square base and h be the height of the rectangular box.

The base and the roof would have an area of $s^2$ and cost of

$4s^2 + 2s^2 = 6s^2$

The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh

So the total cost for the material is

$6s^2 + 10sh = 450$

$10sh = 450 - 6s^2$

$h = 45/s - 0.6s$

The volume of the shed has the following formula

$V = s^2h = s^2(45/s - 0.6s) = 45s - 0.6s^3$

To find the maximum value for V, we can take its first derivative, and set it to 0

$\frac{dV}{ds} = 45 - 1.2s^2 = 0$

$1.2s^2 = 45$

$s^2 = 45 / 1.2 = 37.5$

$s = \sqrt{37.5} = 6.124 ft$

h = 45/s - 0.6s = 3.674 ft

So the equation 12 y equals 132 the equation 12 y equals 132

OlgaM077 [116]

12y = 132

Now, solve for y.

Do the inverse operation.

12y = 132
12y/12 = 132/12
y= 132/12
y= 11

Equation: 12y = 132
Y equals: 11

Mia's outfit is having a sale. If Sam buys 3 shirts at the regular price, he will get 2 free shirts. How much will each shirt co

Dominik [7]

Answer: 3/5

Step-by-step explanation:

The price of 1 shirt is x and 5 shirts is 5x but she pays for only 3 of them. You would divide 5 by 3 giving you 3/5 which would be the cost of all the shirts
