Answer:

The total cash received is $30740.

Step-by-step explanation:

Montana Company sold merchandise with a retail price of $ 29,000 for cash. Montana Company is required to collect a 6 % state sales tax.

Therefore, the total cash received from customer = Retail Price + State Sales Tax.

= $29000 + 29000 \times \frac{6}{100}$

= $30740

Hence, the total cash received is $30740. (Answer)

What is the measure of angle x? Enter your answer in the box. m∠x= °

Llana [10]

The value of x is 83.
This is because all three angles of a triangle must sum up to 180 degrees. So 53+44=97 and 180-97=83.

Plz help this one is the last one of the day plz help

Juliette [100K]

We know 20% is 15
and now we find 80%

since 20% x 4 = 80%, we can multiply 15 by 4 to get 80% of 75

15 x 4 = 60

80% of 75 = 60

1. Do you the following side lengths form a right triangle?2. Which measurement is closest to the value of X in centimeters?

koban [17]

Answer:

Part 1:

Yes, the side lengths form a right triangle.

Part 2:

Option d 37.1 cm

Explanation:

We need to use the pythagorean theorem.

In part 1, if the 3 side lengths are a right triangle, then, they must verify:

$7.5^2=4.5^2+6^2$

By the theorem. Then:

$\begin{gathered} 7.5^2=56.25 \\ 4.5^2+6^2=20.25+36=56.25 \end{gathered}$

They're equal, then the lengths correspond to a right triangle.

For part 2, we need to use again the theorem. In this case:

$\begin{gathered} 12^2+x^2=39^2 \\ x=\sqrt{1521-144} \\ x=\sqrt{1377} \\ x\approx37.1cm \end{gathered}$
