Can someone help me?

Hi Eli!

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

We Know:

1 1/2 cups of flour.

3/4 cup of white sugar.

1/8 cup of brown sugar.

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

Part A:

I can't use a number line answering this question but you can create one with the steps I tell you.

First find common denominators:

1 1/2 = 3/2 = 12/8

3/4 = 6/8

1/8

Create a number that goes from 0/8 to 12/8, which means put a number with 12, 1/8 plots on it. Then plot 12/8, 6/8, and 1/8 in order in the number line.

Find out the total number of cups used:

12/8 + 6/8 + 1/8 = 19/8

Simplify:

19/8 = 2 3/84

Part A Answer: There are <u>2 3/8 cups</u> used all together.

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

Part B:

Part B Answer: The <u>3 cup bowl</u> would work perfectly.

Why: The reason you would want to choose the 3 cup bowl is because it fits all the ingredients perfectly, the 3 cup bowl is greater than the 2 3/8 cups they used. You can't use 2 cups because it is less than the total cups of ingredients. The 4 bowl you could use but it is too big.

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

Hope This Helps :)

Solve for x (Show work)
34kurt

Answer:

x \approx 36.57

Step-by-step explanation:

Let the length of the perpendicular be y units.

So,. By Pythagoras Theorem:

{y}^{2}  =  {32}^{2}  -  {28}^{2}  \\    = (32 + 28)(32 - 28) \\  = 60(4) \\   {y}^{2} = 240 \\  \\ by \: geometric \: mean \: property \\  {y}^{2}  = 28(x - 28) \\  240 = 28x - 784 \\ 240 + 784 = 28x \\  1024 = 28x \\  x =  \frac{1024}{28}  \\  x = 36.5714286 \\ x \approx 36.57
