A candy store called "Sugar" built a giant sugar cube out of wood to hang above the entrance to their store. It took 545454 feet

DedPeter [7]

Answer:

The volume inside the giant sugar cube is 27 cubic feet.

Step-by-step explanation:

It took 54 feet² of material to build the giant sugar cube. That means, the total surface area of the cube is 54 feet²

Formula for surface area of a cube is: $S= 6a^2$ , where $a$ is the length of each edge of the cube.

So, we will get.........

$6a^2=54\\ \\ a^2= \frac{54}{6}=9 \\ \\a= \sqrt{9}= 3$

Now, the volume of the cube will be: $V= a^3= (3)^3 = 27$ feet³

Thus, the volume inside the giant sugar cube is 27 cubic feet.

Solve |x| > -9. No solution All reals { x | x < -9 or x > 9}

neonofarm [45]

All reals is the answer.

Since y =-9 graph is way below the absolute value graph. Meaning that y value of modulus is greater than the constant graph.

The grocery store where Ms. Maple works pays her $6.50 per hour. Any time she works more than 40 hours per week, she is paid tim

Charra [1.4K]

Answer:

$289.25

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.
