Find the area of the right triangle. If necessary, round to the nearest tenth.
Ne4ueva [31]

Answer:

B - 150 yd

Step-by-step explanation:

Obviously the first step is to find the missing measurement. To do this, you use the Pythagorean theorem; <em>a² + b² = c².</em>

In this case, let's label the the missing side A, the height B, and the hypotenuse C.

<em>X² + 15² = 25²</em>

Then you must figure out what 15² and 25².

<em>15² = 225</em>

<em>25² = 625</em>

The next step is to subtract 15² (225) from 25² (625), which will give you the result of X².

<em>625 - 225 = 400. </em>

Now you know X² = 400, you can find the square root of 400 to give you the length of the triangle.

<em>√400 = 20.</em>

<u>The missing length of the triangle is 20 yards. </u>

Now it's just a matter of finding the area by using the formula;

<em>A = </em>\frac{bh}{2}

Or,

<em>(20 × 15) ÷ 2 = 150.</em>

<u>And there's your answer. Don't forget to add the units.</u>

What is the simplest form of
ASHA 777 [7]

Step-by-step explanation:

step 1. the cube root is also to the 1/3 power

step 2. (27a^3b^7)^(1/3) = (3*3*3*a*a*a*b*b*b*b*b*b*b)^(1/3)

step 3. a third root: 3 factors in the root comes "out" of the root as 1

step 4. 3ab*b(b)^(1/3) = 3ab^2(b)^(1/3).

Find the area of a circle with the diameter of 3 centimeters. Use 3.14 for pi ().
wlad13 [49]

Answer:

7.065 sq. cm

Step-by-step explanation:

Diameter= 3 cm

Since 2r=d, the radius is 1.5 cm

Circle area formula:

πr^2 --> 3.14(r^2)

Plug in r:

A=3.14(1.5^2)

A=3.14(2.25)

A=7.065
