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

What is y = mx + b mean for functions
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

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
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

Carmine pain an electrician x dollars per hour for a 5 hour job plus 70 for parts. The total charge was 320 which equation can be used to determine how much do electrician charge per hour
Answer:
5x + 70 = 320
Step-by-step explanation:
We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.
He also got paid 70 for parts, meaning an extra $70
And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.
Therefore :
5x + 70 = 320
Which problem solving strategy would be best to solve this problem?
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
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.
The triangles are similar.
What is the value of x?
Enter your answer in the box.
Answer: 16 units
Step-by-step explanation:
In similar triangles, the sides keep the same ratio, in this case 3:4:5.
Thus, because 12 is 3*4 and 20 is 5*4, x must be 4*4, or 16.

Round 1.2 to the nearest whole number.
Answer:
1
Step-by-step explanation:
When rounding to the nearest whole number by looking at the tenth's value. Remember if it is 5 or more you would raise the number while if it is 4 or less you would round down. In your case you would round down.
0.5, 0.6, 0.7, 0.8, 0.9=1 if rounded to nearest whole number.
0.1, 0.2, 0.3, 0.4=0 if rounded to nearest whole number.
Hope this helps!
