1 answer:

8 0

$a=5m;\ H=13m\\\\The\ volume\ of\ a\ square\ pyramid:V=\frac{1}{3}a^2H\\\\Subtitute\ the\ values\ of\ a\ and\ H:\\\\\boxed{V=\frac{1}{3}\cdot5^2\cdot13=\frac{1}{3}\cdot25\cdot13=\frac{325}{3}=108\frac{1}{3}\ (m^3)}$

You are making a necklace that is 9 inches long. You use 6 beads for each inch. What integer is the change in your supply of bea

nydimaria [60]

To answer this question we first must know the definition of an integer. An Integer is a whole number. 1, 10, 100 are all integers. 1.3 and 0.75 are not. So now we must multiply the number of beads per inch by the total number of inches: The question states you use 6 beads for each inch. So 6 beads per inch multiplied by 9 inches is 54 beads. So your supply changes by 54 beads.

The perimeter of a rectangle is 60. The length is twice the width. Find the length and width.

prohojiy [21]

Step-by-step explanation: Our first task in this problem is to setup variables representing length and width and we do that by using the second sentence.

The length is twice the width

So if we call our width x, that means that our length is 2 times x or 2x

Width of the rectangle ⇒ x

Length of the rectangle ⇒ 2x

Before moving on, go ahead and draw a picture of your

rectangle so that you can visualize what's going on.

I have done this for you below.

We label our widths x and our lengths 2x.

Now we can use the first sentence to setup our equation.

The perimeter of a rectangle is the distance

around the outside of the figure.

So if our perimeter is 60, that means that x + x + 2x + 2x = 60.

Simplifying by combining like terms, we get 6x = 60.

Now dividing both sides by 6, we find that x = 10.

Since x represents width, our width is 10.

Our length therefore with be 2(10) or 20.

So our width is 10 and our length is 20.

1. Use the data points about the distance and elevations of the camps to graph the data points where the x-coordinate is the tot

Vadim26 [7]

You should plot the total distance traveled from the base camp on the x-coordinate while the elevation should be plotted on the y-coordinate.

<h3>What is a graph?</h3>

A graph simply refers to a type of chart which is commonly used to graphically represent data on both the vertical and horizontal lines of a cartesian coordinate (x-coordinate and y-coordinate).

<h3>How to plot this graph?</h3>

In this scenario, you would plot the total distance traveled from the base camp on the x-coordinate while the elevation of the camps would be plotted on the y-coordinate as shown in the image attached below.
