The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 34 ft long, what is its volume?

Answers

Given:

The diameter of the cylindrical pipe = 6ft.

Height of the pipe = 34 ft

To find:

The volume of the pipe.

Solution:

We have,

Diameter of cylinder = 6 ft

Radius of cylinder [tex]=\dfrac{6}{2}=3[/tex] ft

Height of the pipe = 34 ft

Volume of a cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting r=3 and h=34, we get

[tex]V=\pi (3)^2(34)[/tex]

[tex]V=\pi (9)(34)[/tex]

[tex]V=306\pi [/tex]

[tex]V=306(3.14)[/tex]

[tex]V=960.84[/tex]

Therefore, the volume of the cylindrical pipe is [tex]306\pi \approx 960.84[/tex] cubic ft.

convert 9 1/9 into a improper fraction

Answers

Answer:

82/9

Step-by-step explanation:

The improper fraction is 82/9.

What is improper fraction?

An improper fraction is a type of fraction where the numerator is greater than or equal to the denominator. For example, 5/2 and 8/5, are improper fractions. Every fraction has two parts, numerator, and denominator. In mathematics, there are two main types of fractions based on the values of numerator and denominator, and those are proper fractions and improper fractions.

A fraction whose numerator is greater than or larger than the denominator is defined as an improper fraction such as 7/3 and 12/5.

Given fraction:

9 1/9

Now, converting into improper fraction

Numerator = 9 x 9 + 1

                   =81 + 1

                   = 82

and, Denominator = 9

So, the improper fraction is 82/9.

Brandon went to the store and spent $2.50 on pencils. He spend half of what he had left on a notebook and paper. When he got home he had $5.00 left. How much money did Brandon have before going to the store?

A) make a table, chart or list
B) work backwards
C) use a formula
D) look for a pattern

Answers

Answer:

B) work backwards.

Step-by-step explanation:

Since they are asking for how much money he had at first and they displayed how much he spent without telling the amount of money at the start of the question, this is definitely a backwards question. For working backwards, you will need to do workings the opposite as what they said in the question.

What is y = mx + b mean for functions

Answers

Answer:

Slope-Intercept Form. A function whose graph is a line or a part of a line is called a linear function. In general, a linear function is a function that can be represented by an equation in the form y = mx + b. The form y = mx + b, or f(x) = mx + b, is called the slope-intercept form of a linear equation

Step-by-step explanation:

hope this help:))

the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

A large hose can fill 7/8 of a water tank in one hour. A small hose can fill 3/4 of a water tank in one hour. How much more of a water
tank can the large hose fill in one hour than the small hose?
can fill

Answers

Answer:

The large hose can fill 1/8 more of the tank in on hour than the small hose

Step-by-step explanation:

To understand this, we need to make 7/8 and 3/4 have the same denominator

3/4 and 6/8 are the same in decimal form (0.75)

So we change 3/4 to 6/8

So now we subtract what the small hose fills per hour from what the large hose fills per hour

7/8 - 6/8 = 1/8

So the large hose fills 1/8 more of the tank per hour than the small hose
