Spencer borrowed $50 from his cousin, who charged him 6% simple interest each year. If Spencer pays his cousin back 3 years later, how much will he owe his cousin?
A
$56
B
$59
С
$68
D
$6
Answers
Given:
Principal = $50
Rate of simple interest = 6%
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest in percentage and t is the number of years.
Putting [tex]P=50,\ r=6,\ t=3[/tex] in the above formula, we get
[tex]I=\dfrac{50\times 6\times 3}{100}[/tex]
[tex]I=\dfrac{900}{100}[/tex]
[tex]I=9[/tex]
Formula for amount is:
[tex]A=P+I[/tex]
Where, P is principal and I is the simple interest.
Putting [tex]P=50,\ I=9[/tex], we get
[tex]A=50+9[/tex]
[tex]A=59[/tex]
Therefore, the correct option is B.

In Circle P, EP = 2, PG = 12, and FP = 4.
What is the measure of PH?
A) 10
B) 16
C) 6
D) 8
Answers
Answer:
6
Step-by-step explanation:
FP * PH = GP * EP
If EP = 2, PG = 12, and FP = 4.
Then 4 * PH = 12 * 2
4 * PH = 12 * 2
step 1 simplify
4 * ph = 4PH
12 * 2 = 24
we now have 4PH = 24
step 2 divide each side by 4
4PH / 4 = PH
24 / 4 = 6
we're left with PH = 6

Solution for the radius of a circle of radius 3 . I'm sorry if I made a mistake, I am not sure of the solution.
But is there a fee for the question?
These two laws can help you in the question:
Circumference = π× diameter of the circle. Circumference = 2×π× radius
The circumference of the yellow circle should be considered as the 18.84.

What minus 9 equals 11
Answers
Answer:
20
Step-by-step explanation:
20 - 9 = 11
I hope this helps
Answer:
20
Step-by-step explanation:
Call the number you're trying to find n.
"What" becomes n.
n - 9 = 11
To "undo" the subtraction and reveal the value of n , ADD 9 to both sides of the equation. (Addition is the inverse operation of subtraction.)
n = 11 + 9 = 20
