Answer:
A. 2^4*5 B. 3^3*2
Step-by-step explanation:
80/2 = 40
40 and 2
20 and 2
10 and 2
5 and 2
So we got 4 2's and one 5 bcz they prime.
27 and 2
9 and 3
3 and 3
So 2 3's and one 2 bcz they prime.
So, he usually does 55 only, but this one day he did 77, 77 - 55 is 22, so he did 22 more this one day.
if we take 55 to be the 100%, what is 22 off of it in percentage anyway?

5.0 m/s
Step-by-step explanation:
Answer:
J=0.15
S=0.05
Step-by-step explanation:
4J+2S=0.70
4J+5S=0.85
Using elimination method
4J+2S=0.70 (1)
4J+5S=0.85 (2)
Subtract (1) from (2)
3S=0.15
Divide both sides by 3
3S/3=0.15/3
S=0.05
Substitute s=0.05 into (1)
4J+2S=0.70
4J+2(0.05)=0.70
4J+0.10=0.70
4J=0.70-0.10
4J=0.60
Divide both sides by 4
4J/4=0.60/4
J=0.15
CHECK:
4J+2S=0.70
4(0.15)+2(0.05)=0.70
0.60+0.10=0.70
0.70=0.70
4J+5S=0.85
4(0.15)+5(0.05)=0.85
0.60+0.25=0.85
0.85=0.85
Step-by-step explanation:first of all we have to find discount amount by using the formula discount% of M.P then finding S.P using the formula M. P -S. P then finding the profit using the formula profit% of S. P and at last we have to find C. P using the formula S. P - profit.
