Phoenix [80]2 years ago
4 0

Answer:

W = 27 L = 9.

Step-by-step explanation:

Do 72 / 8 and NOT 72/4. The reason why its not 72/4 is because its talking about the perimeter. We are finding the length so we get 9 for the length. The width is 3 times the length so the width is 27.

A human body has about 6x10^2 times as many red blood cells
Setler [38]

Answer:

Humans are complex organisms made up of trillions of cells, each with their own structure and function.

Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion. Written out, that’s 30,000,000,000,000!

These cells all work in harmony to carry out all the basic functions necessary for humans to survive. But it’s not just human cells inside your body. Scientists estimate that the number of bacterial cells in the human body likely exceeds the number of human cells.

What is the value of X?
d1i1m1o1n [39]

Answer:

x=10

Step-by-step explanation:

We can use the angle bisector theorem to solve this problem

8             12

-------- = ---------

x+4         2x+1

Using cross products

8(2x+1) = 12(x+4)

Distribute

16x+8 = 12x+48

Subtract 12x from each side

16x -12x +8 = 12x-12x +48

4x +8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

4x/4 = 40/4

x=10
