Answer: 33.33%

This MAY be wrong, but when I calculated it, the total discount came out to 149.985, which I think can be rounded up to 150

What’s the volume of the pyramid in the diagram?

dusya [7]

The volume is 675 because when you multiply 20x15 you get 300 and when you multiply 25x15 you get 375. When you add 375+300 you get 675 as your volume.

What is the take from ten strategy

Gekata [30.6K]

It is like when you have the problem 15*6, you don't know how to do that mentally, unless you use the take ten strategy which would turn it into (10*6) + (5*6) so, it simplifies to (60) + (30) which is 90

Can someone help me with all these questions please!! it’s very annoying when people just put something for points ... if u don’

lina2011 [118]

Answer:

Step-by-step explanation:

15) tanA = 6.8/3.0

16) tanR = 9/24

17) tanB = 16/17

18) BC = 10tan40

19) PQ = 38/tan75

20 BC seems to be missing some of its length number I will call it 14

redo if that is incorrect.

∠A = arctan(14 / 14.5)

∠C = arctan(14.5 / 14)

Hink About the Process A right rectangular prism has length

igomit [66]

Answer:

The length has 3 cubes

The width has 7 cubes

The height has 5 cubes

Step-by-step explanation:

Given

$Length = 1\frac{1}{2}yd$

$Width = 3\frac{1}{2}yd$

$Height = 2\frac{1}{2}yd$

$l = \frac{1}{2}yd$ --- edge length

Required

Determine the number of cubes in each dimension

To do this, we divide the dimension by the edge length

<u>For the length, we have:</u>

$n_{Length} = \frac{Length}{l}$

$n_{Length} = \frac{1\frac{1}{2}}{\frac{1}{2}}$

Express as:

$n_{Length} = 1\frac{1}{2} \div \frac{1}{2}$

Change to product

$n_{Length} = 1\frac{1}{2} * \frac{2}{1}$

$n_{Length} = 1\frac{1}{2} * 2$

$n_{Length} = 3$

<em>3 cubes in the length</em>

<u>For the width, we have:</u>

$n_{Width} = \frac{Width}{l}$

$n_{Width} = \frac{3\frac{1}{2}}{\frac{1}{2}}$

Express as:

$n_{Width} = 3\frac{1}{2} \div \frac{1}{2}$

Change to product

$n_{Width} = 3\frac{1}{2} * \frac{2}{1}$

$n_{Width} = 3\frac{1}{2} * 2$

$n_{Width} = 7$

<em>7 cubes in the width</em>

<u>For the height, we have:</u>

$n_{Height} = \frac{Height}{l}$

$n_{Height} = \frac{2\frac{1}{2}}{\frac{1}{2}}$

Express as:

$n_{Height} = 2\frac{1}{2} \div \frac{1}{2}$

Change to product

$n_{Height} = 2\frac{1}{2} * \frac{2}{1}$

$n_{Height} = 2\frac{1}{2} * 2$

$n_{Height} = 5$

<em>7 cubes in the height</em>
