Answer:

V=576 yards^3

Step-by-step explanation:

Since the formula for the volume of a pyramid is V=1/3Bh

You would do V= 1/3 (144) (12)

You get 144 (the area of the base) by doing s^2 since that is the formula for the area of a square since it says, "pyramid with a square 12-yard base" you would do 12^2=144

Knowing all that you then solve. Giving you a Answer of V=576 yards^3

Step-by-step explanation:

Given that,

Perpendicular = 17 units

Hypotenuse = 25 units

We need to find the value of x.

Using Pythagoras theorem to find x.

Hypotenuse² = base²+perpendicular²

25² = x² + 17²

x = 18.3 units

So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.

A model of a famous statue is 1 and one fourth inches tall. The actual statue is 6 and two thirds feet tall. What is the ratio o
Studentka2010 [4]
First, you need to convert 5 1/4 feet to inches. 5.25 x 12 = 63 inches. The ratio of the height of the model to the height of the actual statue in simplest form is 1/42. I don't know if this is correct but I hope this helps you in any way.

Hi there!
The question sounds really complex, but the mathematical operations behind it is figuratively simple. Here, we are told to find 19 (18.7 rounded up is 19) percent of 1,000. To do this, we can set up a proportion to model the whole scenario.
\frac{x}{1000} = \frac{19}{100}
Now, just solve for x by cross multiplying and simplifying.
\frac{x}{1000} = \frac{19}{100}

100x = 19000
x=190
Therefore, 190 people out of 1,000 people leave out pertinent information on their IRS forms. Hope this helped and have a terrific day!

How do you do this question?
Bess [88]

"T<u>he function is decreasing":</u>

This means the slope of the function will be negative at the given point.  Anywhere the line is going down, from left to right, is decreasing.  This eliminates choices A and C.

<u>"The function is concave down":</u>

This means the curve of the function will be open down (think of an upside down u).  This eliminates choice E.

<u>"f(x)>0":</u>

This is anywhere the curve is above the x axis.  This eliminates choice D.

The answer is Choice B) x=2.

Hope this helps!!
