Answer:

\boxed{\sf B)\: x=\sqrt{17}}

Step-by-step explanation:

<u>Use the Pythagorean Theorem</u>

The equation for the Pythagorean Theorem is \tt a^2+b^2=c^2

* a and b are the lengths of the legs, and c is the hypotenuse.*

(To know which side is the hypotenuse look at longest side which is across the right angle).

a= x, b=8, c=9

\sf a^2+b^2=c^2

Let's Plug in the side lengths:

\sf x^2+8^2=9^2

Evaluate 8^2 and 9^2:

\sf x^2+64=81

Subtract 64 from both sides:

\sf x^2+64-64=81-64

\sf x^2=17

Take the square root of both sides:

\sf x=\sqrt{17}

140 fluid ounces increased by 45%
Leokris [45]
First divided 140 by 100 to find out how much 1 percent is
140 ÷ 100 = 1.4

multiply 1.4 by 45 to find 45 %; 1.4 x 45 = 63

then add 63, which is 45%, to 140, which is 100%, and you get 203, which is 140 + 45%, or 145%

please mark brainliest if this helped you. I hope it did!

Find the length of the third side. If necessary, write in simplest radical form.
Zanzabum

Answer:

Step-by-step explanation:

We have to find a leg, so we have to use the Pythagorean theorem in this way:

\sqrt{7^2 - 4^2} = \sqrt{49 - 16} = \sqrt{33}

What is the amount of down payment on the house that cost $65,250? ​
Zarrin [17]
Depends on how much percent you have to put down for the house. Like if it’s 10% then just subtract 10% from the cost of the house.

Please help i have 2 questions thank you very much.
Rudik [331]
Hello!

Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards

15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333

Multiply these to find the volume

5 * 5 * 0.08333 = 2.08325

Multiply this by the cost

2.08325 * 46 = 95.83

The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2

You have to find the volume of the first pyramid

The equation we use is V = \frac{lwh}{3}

V is volume
l is length
w is width
h is height

Put in the values we know

V =  \frac{16 * 16 * 28}{3}

Multiply

V =  \frac{7168}{3}

Divide

V = 2389.3333

Now we use this to find the side length of the second pyramid

2389.333 =  \frac{lw * 112}{3}

Multiply both sides by 3

<span>7167.999 = lw * 112
</span>
Divide both sides by 112

63.9999 = lw

Since it is a square pyramid we know that sides are equal

63.999 = l^2

Take the square root of both sides

8 = l

The answer is B) 8in

Hope this helps!
