Answer:  NOT a right triangle

<u>Step-by-step explanation:</u>

If it is a right triangle, the sum of the squares of the shorter sides must equal the square of the larger side.

7² + 8² = 14²

49 + 64 = 196

    113    = 196     FALSE!

These side lengths do not form a right triangle.

Answer:

1) 36 square units.

2) 190 square units.

Step-by-step explanation:

As you can see, the figures are trapezoids, therefore, you can calculate the area of each one of them with the following formula:

A=(\frac{B+b}{2})h

Where:

<em>B</em> is the longer base,<em> b</em> is the shorter base and <em>h</em> is the height.

Then:

1) B=4units+(8units-2units)=4units+6units=10units\\b=8units\\h=4units

A=(\frac{10units+8units}{2})(4units)=36units^{2}

2) B=3units+15units+5units=23units\\b=15units\\h=10units

A=(\frac{23units+15units}{2})(10units)=190units^{2}

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
laila [671]

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
