You but a spinning top for younger cousin the spinning top is a square pyramid the side length of the base of the spinning top i

dezoksy [38]

Answer:

$10,922\frac{2}{3}\ mm^{3}$

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

where

b is the length side of the base

h is the height of the pyramid

In this problem we have

$b=32\ mm$

$h=32\ mm$

substitute

$V=\frac{1}{3}(32^{2})(32)=(32,768/3)\ mm^{3}$

Convert to mixed number

$\frac{32,768}{3}=\frac{32,766}{3} +\frac{2}{3} =10,922\frac{2}{3}\ mm^{3}$

What is the volume of 4/5 3 1/2 3 1/8

scZoUnD [109]

If you would like to know the volume, you can calculate this using the following steps:

volume = 4/5 * 3 1/2 * 3 1/8 = 4/5 * 7/2 * 25/8 = (5*7)/(2*2) = 35/4 = 8.75

The correct result would be 35/4.

The length of a rectangle is 3 centimeters less than twice its width. If the perimeter of the rectangle is 18 centimeters. find

Ede4ka [16]

Answer:

equation: w +(2w -3) = 18/2
length = 5 cm
width = 4 cm

Step-by-step explanation:

Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:

w + (2w -3) = 18/2

3w -3 = 9 . . . . collect terms

3w = 12 . . . . add 3

w = 4 . . . . divide by 3

2w-3 = 2·4 -3 = 5 . . . . length

The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.

Which of the following functions shown in the table below is not an exponential function?

kramer

Answer:

B. f(x)

D. h(x)

Step-by-step explanation:

An exponential function will have a common ratio.

We check and see if the consecutive terms has a common ratio.

For f(x),

$\frac{5}{2} \ne \frac{10}{5}$

This is not an exponential sequence.

For g(x), we have:

$\frac{2}{1} = \frac{4}{2} = \frac{8}{4} = 2$

For h(x),

$\frac{1.25}{1} \ne \frac{1.5}{1.25}$

This is not an exponential sequence

For k(x),

$\frac{16}{64} = \frac{4}{16} = \frac{1}{4} = \frac{0.25}{1}$
