If you spent 1/2 at the theater, and 1/4 at the arcade then you spent 3/4 of your money leaving you with 1/4 left. multiply the amount of money you have left ($17.50), by 4. You originally had $70. hope this helps!

Well... 2/4+1/4=3/4
Or in other words, You spent 3/4 of your money (Half from Theater and 1/4 from the Arcade) and you have 1/4 of your money now
$17.50 is 1/4 of your money you had before you spent all the money.
To find the answer, you will multiply $17.50×4, since in this situation, you had 4/4 of money.
$17.50×4=$70.00
You had $70 before you spent your money
Hope this helped :D

5.Solve the quadratic equation.

Dafna1 [17]

Answer:

x=5 twice

Step-by-step explanation:

x^2-10x+25=0

multiply the coefficient of x^2 and the last term

1X25=25

find two numbers you can multiply to get 25 and add to get -10

-5 + (-5)=-10 the middle term

replace -10x with -5x -5x and solve the equation

x^2-5x-5x+25=0

factorise by grouping

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

Either x-5=0,x=5 or x-5=0,x=5

Therefore x=5 twice.

Find the volume of each figure. Simplify your answers.

Lerok [7]

Answer:

$98.28\:\mathrm{ft^3}$

Step-by-step explanation:

The volume of a rectangular prism is given by $V=l\cdot w\cdot h$ , where $l$ is the length of the prism, $w$ is the width of the prism, and $h$ is the height of the prism.

Substituting given values, we get:

$V=2.5\cdot 4.25\cdot 9.25=98.28125\approx \boxed{98.28\:\mathrm{ft^3}}$

Since "Simplify your answers" is very subjective, I've rounded to the nearest hundredth as that is reasonably universal, but you may need to adjust the rounding as desired.
