Answer:
25 years old
Step-by-step explanation:
karima is 20 years old
Sarah is 2 years older than karima (20+2= 22)
Noha is 3 years older than Sarah
if sara is 22 then noha is 22+3=25
Because the shadow doubled, the tree is actually only 11 FEET TALL.
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
Answer:
Step-by-step explanation:
Formula for perimeter of a rectangle:
= width
= length
Since the length is twice the width,
.
So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,
And after some simplification, we are left with,
