Divide 80 in a ratio of 3:2, with how you worked it out also please.

1 answer:

4 0

So your total is 5, 3+2=5, so divide 80 by 5 and get 16. then multiply 16 by 3 to get 48 and 16 by 2 to get 32. your ratio is 48:32

Gelneren [198K]

Answer:

The pressure at 50 feet is 2.51515 atm

Step-by-step explanation:

we are given equation as

$p(d)=1+\frac{d}{33}$

where

p(d) gives the pressure, in atmospheres (atm)

a depth d in the sea (d is in feet)

We are given

d=50 feet

So, we can plug d=50 and find p

$p(50)=1+\frac{50}{33}$

$p(50)=2.51515atm$

So,

The pressure at 50 feet is 2.51515 atm

Find RS. R S 22 X Q T 26 I don’t know how to do this one.

Ahat [919]

Answer:

RS is about 18.615

Step-by-step explanation:

since XY is the midsegment, it is parallel to the other 2 lines. That also makes the lines proportional

$\frac{22}{26} =\frac{x}{22}$

cross multiple

484=26x

x= 18.615

A number has two digits. The digit at tens place is four times the digit at units place. If 54 is subtracted from the number, th

iren2701 [21]

"The digit at tens place is four times the digit at units place."

How many possible numbers are there?

1 in the units place: 41

2 in the units place: 82

If you try 3 in the units place, 4 * 3 = 12, you'd get 123, and now it's a three-digit number, so the only possibilities are 41 and 82.

41 or 82

If you subtract 54 from 41, you get a negative number, so 41 cannot be the number.

82 - 54 = 28, which has the digits of 82 in reverse order.

Answer: 82

A 32 foot tall tree casts a shadow that is 48 feet long How far away from the tree is a 6 ft person

dedylja [7]

Answer:

39 feet

Step-by-step explanation:

In the attached diagram

The height of the tree = AB

The height of the man =DE

The length of the shadow =BC

We want to determine how far away from the tree the person is, i.e. |AD|=y

In Triangle ABC

$Tan \theta=\dfrac{32}{48}$

In Triangle CED

$Tan \theta=\dfrac{6}{48-y}$

Therefore:

$Tan \theta=\dfrac{32}{48}=\dfrac{6}{48-y}\\\dfrac{32}{48}=\dfrac{6}{48-y}\\$Cross Multiply\\32(48-y)=48*6\\1536-32y=288\\32y=1536-288\\32y=1248\\Divide both sides by 32\\y=39$

Therefore, the distance of the man from the tree is 39 feet.
