krok68 [10]

Answer:

An expression for the perimeter of the square as a product using the expression for the length of one side 4(12x-\frac{3}{2}).

Step-by-step explanation:

Given : The perimeter of a square is represented by the expression 48x-6 feet.

To find : Write an expression for the perimeter of the square as a product using the expression for the length of one side ?

Solution :

We know that the perimeter of the square is 4 times the side of square.

The perimeter of a square is represented by the expression 48x-6 feet.

Divide the expression by 4,

\frac{48x-6}{4}=12x-\frac{3}{2}

So, the perimeter is also written as 4(12x-\frac{3}{2}) with length of side 12x-\frac{3}{2}

Therefore, an expression for the perimeter of the square as a product using the expression for the length of one side 4(12x-\frac{3}{2}).

Which graph is and is not a function!?​
tresset_1 [31]

Answer:

The first one is a function. The other two are not functions.

Step-by-step explanation:

To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.

Good Luck! I hope this helps!

Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. he currently has a 40% solution and a 70% solution. ho
ludmilkaskok [199]

x = liters of 40% solution

y = liters of 70% solution

Gabe needs 30 liters, so

x + y = 30

Each liter of 40% solution contributes 0.4x liter of acid; each liter of 70% solution contributes 0.7y liter of acid. Gabe needs a solution with concentration 60%, which from 30 liters amounts to a net volume of 0.6*30 = 18 liters of acid. So

0.4x + 0.7y = 18

Solve the system however you like. By substitution, we have

y = 30 - x

0.4x + 0.7(30 - x) = 18

0.4x + 21 - 0.7x = 18

3 = 0.3x

==> x = 10 ==> y = 20
