Answer:

They got 21 wins when they have 6 losses

Step-by-step explanation:

you need to multiply 2 by whatever will get you to 6.

2*3=6

and what you do to one side you do to another side.

7*3=21

The ratio is 21:6

If you need to fill the table, you can multiply two by two and two by 4

wins | 7 | 14 | 21 | 28 |

loss | 2 | 4 | 6 | 8 |

Calculate the surface area and show work :) please help me no links!!

eimsori [14]

Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

Explain:

To find the surface area of a rectangular prism, use this formula:

$SA=2lw+2lh+2wh$

$SA=2(lw+lh+wh)$

$l-length$

$w-width$

$h-height$

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

Solve:

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

$SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2$

------------------------------------------------------------------------------------

Conclude:

I, therefore, believe the area of this rectangular prism is 294 in.²

DanielleElmas [232]

Answer:

(2000 - 100x)(5 + x)》12000

10000 - 500x + 2000x - 100x²》12000

-100x² + 1500x + 10000》12000

x for max profit:

-200x + 1500 = 0

x = 7.5

Price = 5 + 7.5 = 12.5

Max profit:

(2000 - 100(7.5))(5 + 7.5)

= 1250 × 12.5

= $15625
