A cylindrical piece of iron pipe is shown below. The wall of the pipe is 0.75 inch thick, and the pipe is open at both ends: The figure shows a cylinder of height 12 inches and diameter 8 inches. What is the approximate inside volume of the pipe? (8 points)
398 cubic inches
603 cubic inches
565 cubic inches
412 cubic inches
Answer:
It's 398
Step-by-step explanation.
Diameter of 8.
height of 12.
8 - .75 - .75= 6.5
6.5/2 = 3.25
3.25 x 3.25 x 12 x 3.14 = 397.995
round to the nearest whole number and you get
398
Take the diameter (8) an subtract is by both sides of the walls (0.75 each wall) that gives you 6.5. Take that 6.5 and half that, because you need to have the radius to solve volume problems, giving you 3.25. Then multiply 3.25 by 3.25 together ( I know it seems redundant but it just works easier this way) This gives you 10.5625. After that take 10.5625 then multiply it into 12, being the height, which gives you 126.75. Finally take 126.75 and multiply that into 3.14 (pie) giving you the answer.
The approximate inside volume of the pipe is 398 cubic inches.
We must use the Volume formula for a right Cylinder to calculate the approximate Inside Volume of the pipe, which is described below:
[tex]V = \pi \cdot (r-t)^{2}\cdot h[/tex] (1)
Where:
[tex]V[/tex] - Inside volume, in cubic inches.
[tex]r[/tex] - Radius of the iron pipe, in inches.
[tex]t[/tex] - Wall thickness of the iron pipe, in inches.
[tex]h[/tex] - Height of the cylinder, in inches.
If we know that [tex]r = 4\,in[/tex], [tex]t = 0.75\,in[/tex] and [tex]h = 12\,in[/tex], then the approximate inside volume of the pipe:
[tex]V = \pi\cdot (4\,in-0.75\,in)^{2}\cdot (12\,in)[/tex]
[tex]V \approx 398.197\,in^{3}[/tex]
The approximate inside volume of the pipe is 398 cubic inches.

Answer:
4x+10=90.
Step-by-step explanation:
The angle EVD forms a right angle. right angles are equal to 90. if the angle is 90 and is shown by the equation 4x+10 then 4x+10=90
Who can help me with this ?
Answer:
I believe the measure of the sum of interior angles of square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360
simplify that, and you get 12x=360
this means x= 30

Moesha needs $79 for a class trip. She already has $22 and she can earn the rest by babysitting for 8 hours. If h represents her hourly earnings,
which of the following equations can be solved to find Moesha's hourly
earnings? Select all that apply.
Answer:
79-22=8h
Step-by-step explanation:
She can earn the rest by babysitting for only 8 hours,
so take 22 from 79, divide the total by 8 and that is how much she gets per hour (8h)
Answer:
79.5 = 22.35 + 8

A. Its slope is 3/2 and goes through (-1, -1).
B. Its slope is 2/3 and goes through (1,4).
C. Its slope is 3/2 and goes through (-3,-2).
D. Its slope is 2/3 and goes through (2,-4).
Answer:
C
Step-by-step explanation:
The line goes right 2 up 3 so the slope must be 3/2. You can track the point (-3,-2) on the line in the graph.

2.3 + ( - 2.3 ) is equal to zero.

-2.6 - ( -12/4 ) is positive.
5/2 + ( -2.5 ) is negative.
72 - ( -100 ) is negative.
Answer:
The 1st and the 3rd one
Step-by-step explanation:
2.3+(-2.3) ➡ 2.3 -2.3 = 0 ,so this option is correct
-3.7+(-4.1) ➡ -3.7 - 4.1 = -7.8 so this option isn't correct
-2.6-(-12/4) ➡-2.6 + 3 = 0.4 this option is also correct
(5/2)+(-2.5) ➡ 5/2 -5/2 = 0 this would be undefined because we can't divide 0 by 2 or any other rational numbers
E.72-(-100) ➡72+100= 172 this option is incorrect because 172 is positive

I just went through all eh choices
It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out
D is impossible becuase you can’t jsut flip a subtraction problem
And A is possible because adding a negative basically means subtracting so if flipped The signs have to change
Literal Equations: Solve for p:
5(4x + p)=w
Answer:
Step-by-step explanation:
Simplifying
5(4x + p) = w
Reorder the terms:
5(p + 4x) = w
(p * 5 + 4x * 5) = w
(5p + 20x) = w
Solving
5p + 20x = w
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-20x' to each side of the equation.
5p + 20x + -20x = w + -20x
Combine like terms: 20x + -20x = 0
5p + 0 = w + -20x
5p = w + -20x
Divide each side by '5'.
p = 0.2w + -4x
Simplifying
p = 0.2w + -4x
Solve for x.
x2 – 13x + 12 = 0
A. x = -12 and x = -1
B. X = -12 and x = 1
C. X= 12 and x = -1
D. X = 12 and x = 1
last one is the answer:D. X=12 and X=1
step by step:
d=b2-4ac=169-48=121
x1=(-b+√d)2a=(13+11)2=12
x2=(-b-√d)2a=(13-11)/2=1
X1=12 and X2=1

In the given figure , AP = BP = PC. Prove that [tex] \angle[/tex]ABC = 1 rt.angle.
~Thanks in advance ! ♡
Answer:
See Below.
Step-by-step explanation:
In the given figure, AP = BP = PC.
And we want to prove that ∠ABC is a right angle.
Since AP = BP and BP = PC, we can create two isosceles triangles: ΔAPB and ΔCPB.
By the definition of isosceles triangles, in ΔAPB, ∠PAB and ∠PBA are equivalent. Let the measure of each of them be x°.
Likewise, in ΔCPB, ∠PCB and ∠PBC are equivalent.
And since AP = BP = PC, each of the angles∠PCB and ∠PBC will also be equivalent to x°.
And since the sum of the interior angles of a triangle total 180°, we acquire:
[tex]\angle PAB+\angle PBA+\angle PCB+\angle PBC=180[/tex]
Since they are all equivalent:
[tex]4x=180[/tex]
Hence:
[tex]x=45^\circ[/tex]
∠ABC is the sum of ∠PBA and ∠PBC, each of which measures 45°. Hence:
[tex]\angle ABC=\angle PBA+\angle PBC=45+45=90^\circ[/tex]

this is your answer look it once.
