elena55 [62]

Just by giving the numbers an analisys, we are able to find the answer, specially because we have options to choose from.

32 is a big part of 48. It's more than half, which would be 24 and would correspond to 50%. Therefore, nor 46 nor 33 can be answers, because 32 is more than the half of 48, so the answer is A.

An angle measures 80° more than the measure of a complementary angle. What is the measure of each angle?
Rom4ik [11]

Supplementary angles sum to 180 degree  

Let one angle be x  

Then the other angle is x+80  

Summing the 2 angle gives  

x+x+80=180

2x+80=180

2x=180-80

X=50

Thus the angles are 50 degree and 50+80= 130 degree

The simple interest on an investment of $8000 for one year is $360.
elena55 [62]
I = PRT
$360 = $8000 x R X 1
$360 = $8000 X R
$360/$8000 X R /$8000
0.045 = R
R= 0.045 * 100
R = 4.5%
