Answer: b = 15, the perimeter is 40, and the area is 60.

Step-by-step explanation: First we need to find b. Using the Pythagorean Theorem, we know what 8^2 + b^2 = 17^2. This is the same as 64 + b^2 = 289. Subtract 64 from each side and we get b^2 = 225, which happens to be 15^2, so b=15. Now that we have b, we can add 8 + 15 + 17 to get the perimeter, 40. The area comes from 1/2*base*height, so 1/2 * 8 * 15. The area of the triangle is 60.

Answer:

A

Step-by-step explanation:

So the whole segment TV is made up of TU plus UV. In an equation:

$TV=TU+UV$

We already know that TV is 32 and UV is 20. Substitute:

$32=TU+20$

Subtract 20 from both sides:

$TU=12$

So, the length of TU is 12.

Our answer is A.

And we're done!

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,

pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities vary directly.

Therefore, we have

$b=kw$ , where k is the constant of variation.

Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have

$5=136k\\
\\
k=\frac{5}{136}$

Thus, the constant of variation is $\frac{5}{136}$

Now, we have been given 3.5 bushels of wheat. Hence, we have

$3.5=\frac{5}{136} w\\
\\
w=\frac{136\times 3.5}{5} \\
\\
w=95.2$

Therefore, 3.5 bushels of wheat weigh 95.2 kg

Gemiola [76]

Answer: 72

We can use ratios

117 inches / 13 inches = 9

The corn cast shadow is 9 times bigger than the example we are given.

9 * 8 = <u><em>72</em></u>
