Answer:
F. 5:4
Step-by-step explanation:
Solve for a and c to find the ratio of a to c:
- 2a = 3b
- a = 3/2(b)
- 6b = 5c
- c = 6/5(b)
Now, we can use the value of a and c to find the ratio of a to c:
- (3/2(b))/(6/5(b))
- 3b/2 × 5/6b
- 15b/12b
- 5/4
F. 5:4 is the correct answer
15=-2(2t-1) -- expand brackets
15=-4t+2 -- subtract 2
13=-4t -- switch signs, best to have a positive variable
4t=-13
t=-13/4
Hello from MrBillDoesMath!
Answer:
b = 28 degrees
Discussion:
In general,
sin (90 - @) = cos(@)
Set 90 [email protected] = 62 => @ = 28 so
sin (90-28) = sin(62) = cos(28) => b = 28
Thank you,
MrB
I think 517.26
I did 10 times 3^2 (9) it equals 90. Then 90 times 3.14 and got 282.74. Then did 800- 282.74 and got 517.26
