Hello,
Answer C
13*(12-3)+3*10=147
Answer:
23.590 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle:
Tan = Opposite/Adjacent
Here, that means ...
tan(65°) = height/(11 ft)
Multiplying by 11 ft, we get ...
height = (11 ft)tan(65°) ≈ 23.5896 ft
height ≈ 23.590 ft
Answer:
20(E)
Step-by-step explanation:
Printing press R, S and T are working together at their respective constant rate.
They can do a job for 4 hours.
Let r, s and t be the time for printing press R, S and T to complete the job alone at their respective constant rate.
Rate of printing press R = 1/r
Rate of printing press S = 1/s
Rate of printing press T = 1/t
Rate = job / time
R + S + T = 4
1/r + 1/s + 1/t = 1/4
S + T = 5
1/s + 1/t = 1/5
Substitute 1/s + 1/t = 1/5 in the equation 1/r + 1/s + 1/t = 1/4
1/r + 1/5 = 1/4
1/r = 1/4 - 1/5
1/r = (5 - 4)/ 20
1/r = 1/20
r = 20 hours
It takes the printing press R 20 hours to complete the job alone

50 is the answer....
Percentage of 70% of what = 35?
70% × ? = 35
? =
35 ÷ 70% =
35 ÷ (70 ÷ 100) =
(100 × 35) ÷ 70 =
3,500 ÷ 70 =
50
