Answer:

20 months or 1 year and 8 months

Step-by-step explanation:

Take 800 and divide it by 40 which equals 20. 20 would be the amount of months that it would take Carmen to pay back her loan. But if you wanted to simplify it into years and months then it would be 1 year and 8 months.

I kind of understand this question, but I'm not sure how to answer it directly, can someone help please.

So here we use the pythagorean theorem which is a2 + b2 = c2 (“a” squared times “b” squared equals “c” squared) the length from calvins house to the intersection is “a” and the length from phoebes house to the intersection is “b” so in order to find out the length of “c” (calvins house to phoebes house) we need to use the pythagorean theorem

a2 275x275=75,625

b2 113x113 = 12,769

so now that we have figured out what a2 and b2 are let’s add them

75,625 + 12,769 = 88,394

now since we only need to find out the length and not the area we need to find the square root of 88,394

the square root of 88,394 is 297.311 (i cut off the decimal after three places)

the direct length from phoebes house to calvins is 297.311 meters

If mx=x+5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Ne4ueva [31]

Answer:c

Step-by-step explanation:

Given

$m\left ( x\right )=x+\frac{5}{x-1}$

and $n\left ( x\right )=x-3$

m of n is given by replacing x in $m\left ( x\right )$ by x-3

$m\left ( n\left ( x\right )\right )=x-3+\frac{5}{x-3-1}=x-3+\frac{5}{x-4}$

$m\left ( n\left ( x\right )\right )$ can take any value of x except x=4 because at x=4 function is not defined

and $h\left ( x\right )=\frac{11}{x-4}$ is also not defined for x=4 and can take any value of x

Points M, N, and P are respectively the midpoints of sides AC , BC , and AB of △ABC. Prove that the area of △MNP is on fourth of

Hunter-Best [27]

Answer:

The area of △MNP is one fourth of the area of △ABC.

Step-by-step explanation:

It is given that the points M, N, and P are the midpoints of sides AC, BC and AB respectively. It means AC, BC and AB are median of the triangle ABC.

Median divides the area of a triangle in two equal parts.

Since the points M, N, and P are the midpoints of sides AC, BC and AB respectively, therefore MN, NP and MP are midsegments of the triangle.

Midsegments are the line segment which are connecting the midpoints of tro sides and parallel to third side. According to midpoint theorem the length of midsegment is half of length of third side.

Since MN, NP and MP are midsegments of the triangle, therefore the length of these sides are half of AB, AC and BC respectively. In triangle ABC and MNP corresponding side are proportional.

$\triangle ABC \sim \triangle NMP$
