Andy borrows $3890 over 4 years. What was the rate per annum of the loan if he paid back $5908?
lesya [120]

Answer:

The formula to get the rate R would be:

principal x (1+R)^time = (principle + interest)

=> 3890 x (1 + R)^4 = 5908

=> (1 + R)^4 = 5908/3890

=> (1 + R)^4 = 1.5188

=> 1 + R = 1.11

=> R = 1.11 - 1 = 0.11 = 11%

Hope this helps!

:)

A. 35<br> B. 85<br> C. 50<br> D. 25
vivado [14]

Answer: B

Step-by-step explanation:

Use the exterior angle theorem, which states that the exterior angle of a triangle is equal to the sum of the two remote interior angles.

In this case: 120-x= 10+x+60

Simplifying it by combining like terms: 120-x=70+x

Solving by isolating the variable: 50= 2x, x=25

Now use what we know, which is that angle A is 35 degrees, and angle B is 60, to find out that the correct answer is B, 85 degrees.

The sum of two numbers is 46 . the larger number is 12 more than the smaller number. what are the numbers?
snow_tiger [21]
X + y = 46
x = y + 12

y + 12 + y = 46
2y + 12 = 46
2y = 46 - 12
2y = 34
y = 34/2
y = 17

x = y + 12
x = 17 + 12
x = 29

so ur 2 numbers are : 29 and 17
