Answer:
0.015625
Step-by-step explanation:
1)
x^-3y^-12 / x^15y^-15
answer is D. last choice
2)
answer is <B'C'D' (third choice)
4)
equivalent 3/9 = 0.33333(3 repeat)
answer is B. second choice
5)
1.7 x 3.5 = 5.95
10^-13 x 10^25 = 10^12
so
= 5.95 x10^12
answer is D. last choice
Answer:
86 is a term in the sequence
Step-by-step explanation:
2; 6; 10; 14; 18;.....
T1=1*4-2=2
T2=2*4-2=6
T3=3*4-2=10
T4=4*4-2=14
T5=5*4-2=18
......................
Tn=n*4-2
n*4-2=86
n*4=88
n=88/4
n=22
86 is T22 in the sequence.
First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
Answer: option A)
