Answer:
Step-by-step explanation:
Check your work here:
1)7/8.
7/8=0.875 and 3/4=0.75
2)3/20.
3/20=0.15 and 12.5%=0.125
3)48.4
increase by 10% means you multiply 44 by 100%+10% or 110% to get 48.4
4)612
decrease by 10% means you multiply 680 by 100%-10% or 90% to get 612
5)36,36,60
132/(3+3+5)*3,132/(3+3+5)*3,132/(3+3+5)*5
6)9.6,22.4
32/10*3, 32/10*7
7)20
14/0.7
8)31.5
18/4*7
9)17/12
2/3=8/12, 3/4=9/12 8/12+9/12=17/12
10)15/4
5*3/4
11)8
2^2+2*2=4+4=8
12)0
(-2)^2+(-2)*2=4-4=0
13)3
3(x-3)=0,(x-3)=0,x=3
14)2/5 or 0.4
5x+1=3,5x=2,x=2/5
15)5n+2
The sequence difference is 5 and the first term is 7
16)20
6(3)+2=18+2=20
17)-5
4(-2)+3=-8+3=-5
18)1
the coefficient of x is 1
19)4pi or 12.56
area of a circle is r^2*pi=2^2*pi=4pi
20)14pi or 43.96
circumference of a circle=2r*pi=2*4*pi=14pi
So,
This is simple multiplication once you've converted the percentage to a decimal.
236.4% = 2.364
Multiply 2.364 by 180.
2.364 * 180 = 425.52 lbs.
Neil Armstrong's space suit would weigh 425.52 lbs. on Jupiter.
