protocol for flushing a cooling water system at a nuclear reactor requires that a drain valve be opened while the fill pumps are active. the drain valve can empty the tank to thr cut-off in 10 minutes. the pump can fill the rank from the cut-off in 14 minutes. during the flushing process, how long will it take for the initially full tank to reach the cut-off level while following the protocol?
Answer:
Step-by-step explanation:
drain empties 1/10 of the desired amount per minute
pump fills 1/14 of the desired amount per minute
when both are active, the net drain is 1/10-1/14 = 1/35 of the desired amount per minute
It takes 35 minutes to reach the cut-off level.

The total number of hours tea that Trent has practiced his guitar after D days is modeled by the equation shown t=3d
Answer:
The complete table is
d t
1 3
3 9
5 15
Step-by-step explanation:
Here is the correct and complete question:
The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.
Complete the table below.
d t
1
3
15
Step-by-step explanation:
For the first space, we are to determine the value of t when d is 1
From the given equation, t = 3d, put d = 1 and determine t
t = 3d
∴ t = 3(1) = 3×1
t = 3
For the second space , we are to determine the value of t when d is 3
Put d = 3 in the equation to determine t
t = 3d
∴ t= 3(3) = 3×3
t = 9
For the third space, we are to determine the value of d when t is 15.
Put t = 15 in the equation and then find d
t = 3d
∴ 15 = 3d
Divide both sides by 3
15/3 = 3d/3
5 = d
∴ d = 5

Step-by-step explanation:
A cone has radius 9 and a height 12. A frustum of this cone has height 4.
What are the radii of the bases of the frustum?
What is the slant height of the frustum?
What is the lateral area of the frustum?
(If you waste an answer it will be removed so don't try and get "Free" points.)
Answer:
Part A)
The lower base has a radius of 9 units, and the upper base has a radius of 6 units.
Part B)
5 units.
Part C)
75π or about 235.62 square units.
Step-by-step explanation:
Please refer to the figure below.
The cone has a radius of 9 units and a total height of 12 units.
A frustum of the cone has a height of 4 units.
Part A)
The lower radius of the frustum will simply be 9 units.
For the upper radius, we will use the properties of similar triangles. We will compare the smaller upper triangle to the overall larger triangle. This yields:
[tex]\displaystyle \frac{12}{8}=\frac{9}{x}[/tex]
Solve for x. Simplify:
[tex]\displaystyle \frac{3}{2}=\frac{9}{x}[/tex]
Cross-multiply:
[tex]18=3x\Rightarrow x=6[/tex]
The upper base has a radius of 6 units.
Part B)
We can first find the total slant height of the entire cone. By using the Pythagorean Theorem, this yields that the total slant height is:
[tex]SH^2=12^2+9^2[/tex]
Simplify:
[tex]SH^2=225\Rightarrow SH=15\text{ units}[/tex]
Now, find the slant height of the upper cone:
[tex](SH_\text{cone})^2=8^2+6^2=100[/tex]
So:
[tex]SH_\text{cone}=10[/tex]
Then the slant height of the frustum will be the cone subtracted from the total. Thus:
[tex]SH_{\text{frustum}}=15-10=5\text{ units}[/tex]
Part C)
We can first find the lateral area of the entire cone. The lateral area is given by:
[tex]LA=\pi r\ell[/tex]
The lateral area of the entire cone will be:
[tex]LA=\pi (9)(15)=135\pi[/tex]
The lateral area of the upper cone will be:
[tex]LA_\text{cone}=\pi(6)(10)=60\pi[/tex]
Then the lateral area of the frustum is:
[tex]LA_\text{frustum}=135\pi-60\pi =75\pi\text{ units}^2\approx235.62\text{ units}^2[/tex]

A river guide buys protein bars and bottles of water for participants on a rafting trip. Including taxes, the river guide pays $ 2.50 for each protein bar and $ 1.25 for each bottle of water, spending a total of exactly $ 22.50 . Which combinations of protein bars and bottles of water are possible for the given amounts? Select ALL that apply.
Answer:
Step-by-step explanation:
2.50 for water
1.25 for protein bar interesting that is exactly half of the water
22.50 exactly was spent
I couldn't come up a slick equation, so I just applied some logic and used brute forced (trail and error) to solve the problem.
2.5Water + 1.25Protein = 22.5
8W + 2P = 22.5
6W + 6P = 22.5
4W + 10P = 22.5
2W + 14P = 22.5
There are the possible combinations of both protein bars AND water, since he bought both. He could have also bought 10 water or 18 protein bars, but that is not part of the combination.

juan drove 126 miles in 3 hours. If he continued at the same rate, how long would it take to travel 336 miles?
Answer:
8 hours
Step-by-step explanation:
First you divide 126 by 3 to get the Miles Per Hour, you should get 42 Miles Per Hour, then, just divide 336 by 42 to get the numbers of hours he will have to drive, (which is 8)
Answer:
8 hours
Step-by-step explanation:
126 miles - 3 hours
336 miles - x hours
Cross multiply
126x = 336 x 3
126x = 1008
Divide both sides by 126
x = 1008/126
x = 8

Joshua buys a bunch of watermelons for $7.75. He plans on feeding his friends watermelon as a snack, and there will be 15 people to feed. What is the unit price for one serving of watermelon? The unit price for 1 serving of watermelon is (round to the hundredths place):
Answer:
$0.52
Step-by-step explanation:
To find the unit cost of one serving of watermelon, divide the price of the bunch of watermelons by the number of people to be fed
unit price = price of the bunch / total people to be fed
$7.75 / 15 = $0.52

Answer:
10 in by 48 in
Step-by-step explanation:
The volume (V) of a rectangular solid is calculated as
V = Ah ( A is the area of the base and h the height )
Here h = 3 and V = 1440 , then
3A = 1440 ( divide both sides by 3 )
A = 480 in²
The area of a rectangle = length × breadth
From the give options
10 × 48 = 480 ← is the only option
A store sells card games for $6.95 each. Board games sell for $15.00 each. Monica
is buying 3 card games and x number of board games. Which equation can be
used to find y, the total price Monica must pay in dollars?
Answer:
20.85+x=y
Step-by-step explanation:
Since Monica is buying 3 card games, we multiply 3*6.95. Then, we have 20.85. Then, we will add x to 20.85 to find y. So final answer is :
20.85+x=y
