Answer:
What is (3.1 times 10 Superscript 5 Baseline) (2.2 times 10 Superscript 7 Baseline) in scientific notation?
5.5 times 10 Superscript 12
6.82 times 10 Superscript 12
5.5 times 10 Superscript 35
6.82 times 10 Superscript 35
Step-by-step explanation:
X(4x-10)^
you can write
a(b)^
where
a = x
and b = (4x-10)
so a*b have two factors a and b
b has also power = so b^ so it is means b*b*b*b*..... so b^ have always factor b
(4x-10)
4x < 10
x<10/4
x < 2.5
If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100. When she solves the problem, m=65%.
13/20 is part out of whole. The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable. Thus we have
13/20 = m/100
Cross multiply:
20*x = 13*100
20x = 1300
Divide both sides by 20:
20x/20 = 1300/20
x = 65
