I think for the question above, instead of 2 · 3^2 · 7 it is <span>2 · 3^2 · 5.
</span>
Two numbers have prime factorizations of 2^2 • 3 • 5 and 2 • 3^2 • 5 (note 2 squared & 3 squared).
Now, to choose the GCF, you choose, for each base factor in either number, the least exponent-ed one; so the GCF needs a factor 2, a factor 3, and a factor 5. Thus the GCF is 30 (their product). [i.e,2 squared is not a common factor]
<span>To create the LCM, you choose, for each base factor in either number, the greatest exponented one. Thus, LCM needs a factor 2 squared, 3 squared, and 5, giving LCM = 4(9)(5) = 180.</span><span />
Answer:
B) 4% of 52
Step-by-step explanation:
A) 0.25 x 52 = 13
B) 4% of 52 = 0.04 x 42 = 2.08
C) 52 ÷ 4 = 13
D) 52/4 = 13
Answer:
t=7(1.75c)
Step-by-step explanation:
If I assume that she does the same number of chores each day the equation is t=7(1.75c)
this is because c is the number of chores
and for each chore she earns 1.75 so then for each day it is 1.75c
there are 7 days in a week so you need to multiply that all by 7
so that is 7(1.75c)
that little equation finds the total amount earned so then it is
t=7(1.75c)
