Which pairs of polygons are congruent?
svetlana [45]

The <em><u>correct answer</u></em> is:

pairs 1 and 3

Explanation:

Congruent figures are the same size and the same shape.

Pair 1 has two polygons that are the same size and same shape; they are congruent.

Pair 2 has two polygons that are not the same size; the "stick" of the t shape of one figure is longer than the "stick" of the second figure.

Pair 3 has two polygons that are the same size and same shape; they are congruent.

Pair 4 has two polygons that are the same shape, but the first figure in green is larger than the second shape in red; this means they are not congruent.

A family is purchasing a house and needs to finance a $195,000 mortgage from the bank with an annual percentage rate (APR) of 5.
Alecsey [184]

Monthly payment is $1082.84.

Solution:

Given data:

Principal = $195000

Rate per year = 5.3\% =\frac{5.3}{100}=0.053

Rate per month = \frac{0.053}{12} =0.004416

Time = 30 × 12 = 360 month

<u>To find the monthly payment using formula:</u>

$\text{Monthly payment}=P\times\frac{r(1+r)^n}{(1+r)^n-1}

                           $=195000\times\frac{0.004416(1+0.004416)^{360}}{(1+0.004416)^{360}-1}

                           $=195000\times\frac{0.004416(1.004416)^{360}}{(1.004416)^{360}-1}

If you simplify this using calculator, we get

                           =1082.84

Monthly payment = $1082.84

Option C is the correct answer.

Hence monthly payment is $1082.84.

What is the difference between 126 1/4 an 78 2/3
Vaselesa [24]
1) find the lcd the lcd is 12
2)rewrite  the fractions 1/4 and 2/3 using 12 as the denominator (second column) you get 3/12 and 8/12
3) since its confusing to subtract 8/12 from 3/12 you need to borrow one form the 126 doing so is the same as taking 12/12 from 126 this change to 125 and the 12/12 adds to the 3/12 making it 15/12
4) subtract 8/12 form 15/12 to get 7/12
5) subtract 78 form 125 to get 47
6) the answer is 47 7/12
