Write the sum of the numbers as the product of their GCF and another sum.

8090 [49]

Answer:

See explanation

Step-by-step explanation:

1. Find the GCF of 40 and 44:

$40=\underline{2\cdot 2}\cdot 2\cdot 5\\ \\44=\underline{2\cdot 2}\cdot 2\cdot 11\\ \\GCF(40,44)=2\cdot 2=4$

So,

$40+44=4\cdot 10+4\cdot 11=4\cdot (10+11)$

2. Find the GCF of 13 and 52:

$13=\underline{13}\\ \\52=2\cdot 2\cdot \underline{13}\\ \\GCF(13,52)=13$

So,

$13+52=13\cdot 1+13\cdot 4=13\cdot (1+4)$

3. Find the GCF of 15 and 81:

$15=\underline{3}\cdot 5\\ \\81=\underline{3}\cdot 3\cdot 3\cdot 3\\ \\GCF(15,81)=3$

So,

$15+81=3\cdot 5+3\cdot 27=3\cdot (5+27)$

4. Find the GCF of 64 and 28:

$64=\underline{2\cdot 2}\cdot 2\cdot 2\cdot 2\cdot 2\\ \\28=\underline{2\cdot 2}\cdot 7\\ \\GCF(64,28)=2\cdot 2=4$

So,

$64+28=4\cdot 16+4\cdot 7=4\cdot (16+7)$

Answer:

Will earn $74.38 in interest or for the total $924.38 for the total amount accrued, principal plus interest

Step-by-step explanation:

I = p x rt

I = 850 x 0.035 x 2.5 = 74.38 (interest)

P' = p + I = 850 + 74.38 = 924.38

The answer to this one is simple.
An equation to model with would be
? * 4 = 56.

To find ? All you have to do is divide 56 by 4.

So the answer to your question is 14 miles per hour.

Hope I did this right and hope I helped you :))))

Arc length = 2 π R (C/360)
where:
C is the central angle of the arc
R is the radius of the arc

arc length = 2 π R (137/360) = 2.39R
