The base of a rectangular pyramid is 13 inches long and 12 inches wide.
The height of the pyramid is 8 inches. What is the volume of the
pyramid?

Answers

Answer 1

Answer:

Area = 1/2 (Base) (Height)

Area = 1/2 (12 in) (8 kn)

Area = 1/2 (96 in)

Area = 48 in^2

Volume = (Area) (Length)

Volume = (48 in^3) (13 in)

Volume = 624 in^3

The Base Of A Rectangular Pyramid Is 13 Inches Long And 12 Inches Wide.The Height Of The Pyramid Is 8
Answer 2

Answer:

V=L•W•H

3=13·12·8

3=416

=416³

Step-by-step explanation:

Finding the Volume of a Rectangular Pyramid

Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.

The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height.

If the cube has a side length s, then each pyramid has an s by s base and height s/2, and its volume is 1/6 the volume of the cube, which is 1/3 base times height. ... They are congruent, so have volume 1/3*base*height as the base is a square the side of the cube and the height is the side of the cube as well.Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

What is the longest iron rod which can be placed flat across the diagonal of a 4m by 2.5m garden shed floor

Answers

Answer:

4.7m

Step-by-step explanation:

the length of longest iron rod which can be placed flat across the diagonal of the garden shed can be determined using the Pythagoras theorem,

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = diagonal

4² + 2.5² = 22.25²

c =√22,25 = 4.7m

Answer:

A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of

change than Ryan's function indicating that Daniel can pack more boxes per hour.

Step-by-step explanation:

Given

Ryan: 3 boxes per hour

Daniel: [tex]y = 4h[/tex]

Required

True statement about their functions

First, we calculate Ryan's function.

In 1 hour, he can pack 3 boxes.

In hours, he can pack 3h boxes.

So, the equation is:

[tex]y = 3h[/tex]

So, we have:

[tex]y = 3h[/tex] ---- Ryan

[tex]y = 4h[/tex] --- Daniel

Both functions represent direct proportional functions.

So, when h increases y also increases.

However, Daniel's function has a greater rate of change because[tex]y = 4h[/tex] implies that he can pack 4 boxes per hour while Ryan can pack 3.

An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.

Answers

The answer is 35.1 cm².

Hope this helps; have a great day!

Question:-

Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.

_______________________________________________

Solution:-

In an equilateral triangle all sides are equal.

Let s = side length = 9 cm

Then, area of equilateral triangle is given as:

A = (√3/4)s²

Putting the value of s here,

A = (√3/4) * (9 cm)²

=> A = (√3/4) * 81 cm²

=> A = √3 * 20.25 cm²

We know that, √3 = 1.732

=> A = 1.732 * 20.25 cm²

=> A = 35.073 cm²

Rounding to one decimal place,

=> A = 35.1 cm²

A tennis ball is launched from a catapult from the ground with an initial velocity of 26fps. What is the maximum height of the ball? When will it attain this height? Use H=-16T2+26T

Answers

Answer:

10.5618feet, 0.8125sec

Step-by-step explanation:

Given the height reached by the catapult expressed by the equation H=-16T^2+26T

At the maximum height, the velocity of the object is zero, hence;

v = dh/dt = 0

-32t + 26 = 0

-32t = -26

t = 26/32

t = 0.8125secs

Hence it will attain the maximum height after 0.8125second

Substitute t = 0.8125s into the expression to get the maximum height

H=-16t^2+26t

H = -16(0.8125)^2 + 26(0.8125)

H = -16(0.6602) + 21.125

H = -10.5632+21.125

H = 10.5618

hence the maximum height reached by the ball is 10.5618feet

A store manager receives a delivery of 10 boxes of lightbulbs. Each box contains 20 lightbulbs. The store manager tests all the lightbulbs in one of the boxes and finds that 4 of them are defective.

Between 25 and 50 lightbulbs will be defective.


More than 80 lightbulbs will be defective.


Between 60 and 80 lightbulbs will be defective.


No more than 25 lightbulbs will be defective.

We can expect that there will be about 4 broken lightbulbs in each of the 10 boxes, which is 40 lightbulbs. This means between 25 and 50 lightbulbs will be defective.
