Hey mate ,
here is your answer
**********************
The average between any two rational numbers is also rational.
(7.7 + 7.9)/2 = 7.8
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal.
2 ones are equal to 0 tens
Answer:
29/4 or 7.25
Step-by-step explanation:
Complimentary angles are two angles that add up to 90
Supplementary angles are two angles that add up to 180
Angle ABC = x
Angle CBD = 7y + 4
Angle DBE = 8y + x
If we can find the measure of angle CBD, then we can find x.
We know that CBD + DBE = 180 because they are supplementary. Therefore...
(7y + 4) + (8y + x) = 180
AND
(7y + 4) + (x) = 90
Now we can use algebra to solve for x and y...
Blah blah blah...
x = 29/4
y = 45/4
Answer:
Solution:
<u>Let's use PRT/100 to find the simple interest.</u>
- 3500 x 7.5 x 3/100 = Interest
- → 35 x 7.5 x 3 = Interest
- → 35 x 7.5 x 3 = Interest
- → $787.5 = Interest
Hence, the simple interest is $787.5.
