Answer : 12%

explanation :

Let the sum of money be P(which is the principal value) and rate of interest be R.

According to the question,

Amount (principal +simple interest) = 8P/5

Time (T) = 5 years

Simple interest (SI) = PRT/100

SI = 5PR/100

Amount = P +SI

8P/5 = P+(5PR/100)

8P/5 = P(100+5R)/100

160 = 100 +5R

5R =60

R = 12

Therefore, rate of interest = 12% p.a.

liberstina [14]

Answer:

Step-by-step explanation:

<u>Prime factors of 2100 are:</u>

  • 2100 = 2*2*3*5*5*7

<u>The single-digit divisors are:</u>

  • 1, 2, 3, 2*2= 4, 5, 2*3= 6, 7

-----------------------------------------------------------------

<u>Another solution is you divide 2100 by all numbers 1 through 9 and list those divisible:</u>

  • 2100/1 = 2100, yes
  • 2100/2 = 1050, yes
  • 2100/3 = 700, yes
  • 2100/4 = 525, yes
  • 2100/5 = 420, yes
  • 2100/6 = 350, yes
  • 2100/7 = 300, yes
  • 2100/8 = 262.5, no
  • 2100/9 = 233.33, no

So all the numbers from 1 to 7

What’s measure of angle C?
Oduvanchick [21]
The angle is 60° because
B is a right angle and that adds to 90°, so dividing 90 by 3 would get 30

30 x 2 = 60

and to check the answer

x = 30

A=30
B=90
C=60

this adds to 180 which is correct because the angles in a triangle add to 180° :)
