Complete interior angle = 540

5th angle = 540 - 402 = 138

a supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combi

We first write the fractions in their decimal forms and find out the ratio.

2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33

Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1

Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds

Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds

Answer:

True the triangle is a right triangle.

Step-by-step explanation:

the Pythagorean Theorem states that $a^{2} +b^{2} =c^{2}$

so,

$85^{2} =7225\\77^{2} =5929\\36^{2} =1296\\5929+1296=7225$

Please show steps when solving this.

$\frac{240 inches}{1 minute}$

We're going to change one unit at a time. Let's start with inches to feet. There are 12 inches in 1 foot. Divide 240 by 12 or multiply by 1/12.

$\frac{240 inches}{1 minute} * \frac{1 foot}{12 inches}=\frac{20 feet}{1 minute}$

Next, let's do the time using the same idea. Remember that there are 60 minutes in 1 hour.

$\frac{20 feet}{1 minute} * \frac{60 minutes}{1 hour} = \frac{1200feet}{1hour}$

Answer: 1200 feet per hour

Hope this helps!
