What is the percentage of 48g of fat out of 70g

Answers

from 70 g, mass of 48 g is fat. The percentage value is the value of a fraction of 100. 
percentage of fat can be calculated using the following formula
percentage of fat = mass of fat / total mass x 100 %
percentage = 48 g / 70 g x 100 % 
                   = 68.6 %
this is interpreted as,  68.6 % of the total mass is fat.

the amount of water in a bottle is reduced by 85% to 120 milliters how many water was originally in the bottle.

Answers

Given:
Rate of reduction : 85%
Remaining volume: 120 ml.

This means that 120 ml is equivalent to 15% of the original volume.

100% - 85% = 15%

120 ml ÷ 15% = 800 ml.

There was 800 ml of water before it was reduced.

800 ml * 85% = 680 ml ⇒ volume reduced
800 ml - 680 ml = 120 ml ⇒ volume left after reduction.

What’s the value of x???

Answers

Answer:

x = 2

Step-by-step explanation:

x is the height of these triangles.  Thus, we know all three sides of either triangle:  height = x; base = 8/2, or 4; and hypotenuse √20.

Using the Pythagorean Theorem, we find x as follows:

x^2 + 4^2 = 20, or

x^2 = 4.  Then x must be 2.  

x = 2
