Suppose y varies directly with x. Write a direct variation equation that relates x and y, y=25 when x=140 what is the value of x

In-s [12.5K]

So the formula for direct variation is y=kxplug In the given values and you'll get 25=k140, solve for k and you get 5/28
so the equation is y=(5/28)xand the answer would be C

A triangular prism is 13 meters long and has a triangular face with a base of 12.6 meters and a height of 16.6 meters. What is t

kolbaska11 [484]

Answer:

1359.54m^3

Step-by-step explanation:

The formula for the volume of a triangular prism is:

1/2( $b \times l )\times h$

b= base

l = length

h= height

Step 1: Plug the numbers into the formula

1/2(12.6*13)*16.6

Step 2: Simplify

163.8*16.6

1359.54

Step 3: Add units

The units used in the question were in meters, so the answer is also in meters.

Volume is always cubed, so it would be to the third power...1359.54m^3

If this answer helped you, I would greatly appreciate if you gave me brainliest :D.

How do you write 3.625 as a fraction

vesna_86 [32]

3.625 as a fraction would be 3 5/8 or 29/8.
You would get that by converting 3.625 to 3 625/1000. You do that because there is a 3 before the decimal- (that is a whole #) and three digits after the decimal (that means it goes into the thousandths place, so the denominator is 1000), Then you take the numbers after the decimal and place it over the 1000. Then you would simply the 3 625/1000 by 125. and get 3 5/8 or as a mixed # 29/8. (Multiply the 8 and 3 to get 24 and add the numerator (5) to get 29. The denominator stays the same.

Hope this helps!
Can u plz mark me as brainliest? I really need it!
