Answer:
let he invest x part of earning at the rate of 8%
simple interest = P*T*R/100 = x*1*8/100 = 0.08x
His invest at the rate of 7.5% = 3050 - x
Again simple interest = P*T*R/100 = (3050 - x)*1*7.5/100 = 228.75 - 0.075x
N0w acc0rding to question
0.08x + 228.75 - 0.075x = 242
0.005x= 13.25
x = 2650
rehman invest 2650 at 8% per year
He invest (3050-2650) = 400 0n 7.5% per year

Answer:
1 1/2 teaspoon of salt is required
Step-by-step explanation:
The recipe requires 3/4 cup of flour and Nick wants to make the recipe using 1 cup of flour.
The recipe requires 1 1/8 teaspoon of salt and Nick wants to know how much salt he heeds.
Consider short description:
3/4 cup of flour - 1 cup of flour,
1 1/8 teaspoon of salt - x teaspoon of salt.
Mathematically, you can wrte a proportion:
<u>3/4 </u> = 1 / x
<u>1 1/8 </u>
Then
3/4 * x = 1 x 1 1/8,
3x/4 = 9/8,
3x x 8 = 4 x 9,
24x = 36,
x = 36/24 = 3/2 = 1 1/2
HA hypotenuse angle is the correct answer. you can verify the hypotenuse and corresponding angle are equivalent therefore the triangles are equal
