Answer:
The change in volume of water in the tank after 35 second is approximately 687223.393 cubic centimeters.
Step-by-step explanation:
Geometrically speaking, the volume of the cylindrical tank ([tex]V[/tex]), measured in cubic centimeters, is determined by the following formula:
[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)
Where:
[tex]r[/tex] - Radius, measured in centimeters.
[tex]h[/tex] - Height, measured in centimeters.
By Differential Calculus, we obtain a formula of the rate of change of the volume of the cylinder ([tex]\dot V[/tex]), measured in cubic centimeters per seconds:
[tex]\dot V = \pi\cdot r^{2}\cdot \dot h[/tex] (2)
Where [tex]\dot h[/tex] is the rate of change of the water level, measured in centimeters per second.
Given that the rate of change of the water level is constant, then the rate of change of the volume of the cylinder is also constant. Hence, the change in the volume of the cylinder ([tex]\Delta V[/tex]), measured in cubic centimeters, is:
[tex]\Delta V = \pi\cdot r^{2}\cdot \dot h \cdot \Delta t[/tex] (3)
If we know that [tex]r = 25\,cm[/tex], [tex]\dot h = 10\,\frac{cm}{s}[/tex] and [tex]\Delta t = 35\,s[/tex], then the change in the volume of water in the tank is:
[tex]\Delta V = \pi\cdot (25\,cm)^{2}\cdot \left(10\,\frac{cm}{s} \right)\cdot (35\,s)[/tex]
[tex]\Delta V \approx 687223.393\,cm^{3}[/tex]
The change in volume of water in the tank after 35 second is approximately 687223.393 cubic centimeters.

What is the measure of ZFGJ?
A. 20°
O B. 40°
O C. 50
O D. 90°
Answer:
C) 50°
Step-by-step explanation:
Δ FJG ≅ Δ IKH
∡J = 90
∡I and ∡F = 40
therefore, ∡G = 180 - (90+40) = 50°

how many vertices does a prism with 54 edges have?
Answer:
13 vertices. In geometry, the augmented hexagonal prism is one of the Johnson solids (J54). As the name suggests, it can be constructed by augmenting a hexagonal prism by attaching a square pyramid (J1) to one of its equatorial faces. When two or three such pyramids are attached, the result may be a parabiaugmented hexagonal prism, a metabiaugmented hexagonal prism or a triaugmented hexagonal prism. Augmented hexagonal prism.
Type: Johnson J53 - J54 - J55
Faces: 2x2 triangles 1+2x2 squares 2 hexagons
Edges: 22
Vertices: 13

The price of a bicycle was reduced from $120 to $90. By what percentage was the price of the bicycle reduced?
Answer:price of the bicycle was reduced by 25%
Step-by-step explanation:
Step 1
Old Price of bicycle = $120
New Price of bicycle= $90
Price decrease= $120-$90= $30
Step 2
Percentage decrease = Decrease / Original price x 100
= (30/120) x 100
1/4 x 100
= 25%
Therefore the percentage decrease in the price is 25%

beth got a job painting dorm rooms at her college. At top speed, she could paint 5 identical rooms during one 6-hour shift. How long did she take to paint each room?
Answer:
Step-by-step explanation:
Beth is painting at a rate of 6/5=1 1/5 room per hours
The time taken by Beth to paint a single rooms is (6/5) hours per room or 1 1/5 hours per room.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that at top speed, Beth could paint 5 identical rooms during one 6 hour shift. Therefore, the time it will take for Beth to paint a single room is,
Time for a single room = Time taken to paint / Number of rooms
= 6 hours / 5 rooms
= (6/5) hours per room
= 1 1/5 hours per room
Hence. the time taken by Beth to paint a single rooms is (6/5) hours per room or 1 1/5 hours per room.

The total charge for a yearly Internet DVD rental membership is $231. A registration fee of $15 is paid up front, and the rest is paid monthly. How much do new members pay each month, m?
Answer:
New members pay each month = $18 per month
Step-by-step explanation:
Given:
Total rental membership = $231
Advance registration fee = $15
Find:
New members pay each month
Computation:
Number of month in year = 12
Fee after registration = $231 - 15$
Fee after registration = $216
New members pay each month = Fee after registration / Number of month in year
New members pay each month = 216 / 12
New members pay each month = $18 per month

X/5 + 6 = 10
44
30
20
-20
Answer:
x = 20
Step-by-step explanation:
The way to solve these problems is by isolating x (getting it by itself on one side).
So let's look at the operations needed! First of all, there's currently a +6 hanging out next to x. We don't want that, so we subtract 6 from both sides.
x/5 + 6 = 10
-6 -6
x/5 = 4
We now see that x is being divided by five. To get just x, we can now multiply both sides by five to get rid of that fraction.
x/5 = 4
*5 *5
x = 20

Ok, so BE and CE are perpendicular. This means that they make a 90 degree angle. we can write in the boxes to signify if you want. We also know that the angles CDE and DCE have the same angle. I don't know how to put this is math terms, but that means that ADE and BCE have to be the same as well. If x(the angle of ADE and BCE)is the same, then CDA must be x + (mystery angle). if ADE and BCE are the same, and a triangle's angles add up to 180, then DAE and EBC must be the same as well. Not sure if this actually helps, I'm not able to give a straight answer but it's the best I can do with what I know.

= 2 next odd number after 5
= 9
roses from the fourth rose bush
= 3 next odd number after 9

The price of an item has been reduced by 20%. The original price was $65. What is the price of the item now?
Answer:
$52
Step-by-step explanation:
1.First find out how much is 20% of $65
So:
20/100 × 65/1 = 1300/100 = 13
So 20% of $65 is $13
2. Subtract the amount of percentage, which is $13, from the original price, which is $65, to get the new price.
So:
$65 - $13 = $52
The new price or price of the item now is $52

A worm crawled the first 4 hours of its journey at speed of 15
meters per hour and the remaining 7 hours at 12 meters per
hour. How far is the whole journey in meters?
meters
Answer:
144 meters.
Step-by-step explanation:
If he starts the first 4 hours at 15 meters per hour, he will have traveled 60 meters. If he does the rest of the 7 at 12 meters per hour, he will have traveled another 84 meters. If you add them together you get a total journey of 144 meters.
Consider the two expressions. Expression 1: -4(9x-2)+3
Expression 2: -36x+k
What value of k will make the two expressions equivalent?
Answer:
11
Step-by-step explanation:
first, distribute the negative four in Expression 1: -36x+8+3
next, set that equal to Expression 2: -36x+11 = -36x+k
finally, add 36x to both sides: 11 = k
In the following, after distributing and solving, find the error.
6(x + 8) = 72
6x + 48 = 72
6x + 48 + 48 = 72 + 48
6x = 120
X = 20
What was the error and explain then give the correct answer.
