The ratio of the height of two similar pyramids is 4:7. The volume of the smaller pyramid is 1,331cm, to the nearest whole numbe
IRISSAK [1]

Answer:

The volume of the larger pyramid is equal to 7,133\ cm^{3}

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

In this problem, the ratio of the height is equal to the scale factor

z=\frac{4}{7}

step 2

Find the volume of the larger pyramid

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z----> the scale factor

x----> volume of the smaller pyramid

y----> volume of the larger pyramid

z^{3}=\frac{x}{y}

we have

z=\frac{4}{7}

x=1,331\ cm^{3}

substitute

(\frac{4}{7})^{3}=\frac{1,331}{y}\\ \\(\frac{64}{343})=\frac{1,331}{y}\\ \\y=343*1,331/64\\ \\y=7,133\ cm^{3}

Please only answer if you can help!! Which statements describe the end behavior of f(x)?
noname [10]

Answer:

Step-by-step explanation:

Let’s start seeing what happens to the left. It stops before x = -1, but it continues to do down

so as x approaches  -1, y approaches -oo

Now we have to see what happens to the right. In the case the graph doesn’t stop and it keeps to go up

so as x approaches oo, y approaches oo

What is 1x+3y=18 in slope intercept form
photoshop1234 [79]

Answer:

y = -x/3 + 6

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form:   x + 3y = 18

<u>Step 2: Rewrite</u>

<em>Find slope-intercept form</em>

  1. Subtract <em>x</em> on both sides:                    3y = -x + 18
  2. Divide 3 on both sides:                       y = -x/3 + 6
