I am not positive on this but I believe the answer is 600/15 because you can then accurately see how many feet the submarine rises per hour.

nataly862011 [7]

Answer:

$42

Step-by-step explanation:

Given that,

Galore Super Store buys the latest video game at a wholesale price of $30.00.

The markup rate at Game's Galore Super Store is 40%.

We need to find the price from the store. It can be calculated as follows :

$C=30+\dfrac{40}{100}\times 30\\\\=30+12\\\\=\$42$

Hence, we will pay $42.

Need help with this ignore what a put in the box it isn’t right

Zarrin [17]

$f=6cm\\g=8cm$

Why?

The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".

Calculating we have:

$TriangleArea=ABCE-ABCD\\\\TriangleArea=60cm^{2}-48cm^{2}=12cm^{2}$

Now, we can calculate "f" by using the formula to calculate the area of the triangle:

$TriangleArea=\frac{b*h}{2}\\\\TriangleArea=\frac{f*4cm}{2}\\\\12cm^{2}*2=f*4cm\\\\\frac{24cm^{2}}{4cm}=f\\\\f=6cm$

Now, finding "g" by using the formula to calculate the area of the rectangle, we have:

$RectangleArea=ABCD\\\\ABCD=Base*Height\\\\48cm^{2}=base*6cm\\\\base=g=\frac{48cm^{2}}{6cm}=8cm$

Hence, we have that:

$f=6cm\\g=8cm$

Have a nice day!

1. Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs the same amount, complete the tab

Lunna [17]

Answer:

1: $1.50

2: $3.00

4: $6.00

5: $7.50

6: $9.00

7: $10.50

8: $12.00

9: $13.50

Step-by-step explanation: To answer this problem you need to divide $4.50 by 3. When you do that you get $1.50 per pound of gummy bears. Then you can either add $1.50 to each amount or multiple them by the x value. Then graph the numbers you get.
