Answers:
- x = 9
- angle QRT = 18 degrees
- angle TRS = 72 degrees
=============================================================
Explanation:
The smaller angles QRT and TRS combine to the angle QRS which is 90 degrees.
(angle QRT) + (angle TRS) = angle QRS
(2x) + (8x) = 90
10x = 90
x = 90/10
x = 9
We'll then use this x value to find each angle
- angle QRT = 2x = 2*9 = 18 degrees
- angle TRS = 8x = 8*9 = 72 degrees
As a way to check the answer,
angle QRT + angle TRS = 18+72 = 90
so the answer is confirmed.
Answer:
$5,537.5
Step-by-step explanation:
So the simple interest formula is A=P(1+rt). T meaning the time (in this case 5 years), P meaning the original amount you put in ($5000), and R meaning the interest rate (2.15%). So if we put those all in 5000(1+2.15x5) it would be 58,750
Answer:
There are 9 distinct possible values for q.
Step-by-step explanation:
Let ab be a positive two-digit integer.
- a×b=q=7k from some positive integer k.
- either a or b is 7, since 7 is a prime number and k can be maximum 9.
- assume a=7, then b can be 1,2,3,4,5,6,7,8,9
- b cannot be 0 because a×b=q has to be positive
- if b=7, then a can be 1,2,3,4,5,6,7,8,9
- in both cases there are 9 distinct values for q, which are 7,14,21,28,35,42,49,56,63
