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.

Anna and her sister Bella are making baby blankets to sell at a boutique. Anna has already completed 5 blankets and can finish 7 more blankets per day. Bella has already completed 2 blankets and can finish 8 more blankets per day. At some point, they will have completed the same number of blankets. How long will that take? How many blankets will each woman have made?
Answer:
5.5 or 5 or 6
Step-by-step explanation:
anne=5+7=12(blankets per day)
bella=2+8=10 (blankets per day)
We need to use the 12 times table and 10 times table and see when they meet up
12, 24, 36, 48, 60
10, 20, 30, 40, 50, 60
it will take 5.5 days or 5 or 6

Answer:
Step-by-step explanation:
F/L=3/2
F=3L/2
F+L=35, using F found above makes this become
3L/2+L=35
3L+2L=70
5L=70
L=14, since F=3L/2
F=3(14)/2
F=21
So she needs
Fruit juice=21 liters
Lemonade=14 liters

2. cos 0°
a) sin 1° b)
c) sin 90° d) tan 90°
B)cos 1°
Answer:
sin 90
Step-by-step explanation:
cos (0)
Using the unit circle, we know that cos 0=1
sin 1 and cos 1 are not equal to 1
sin 90 =1
tan 90 = sin 90/ cos 90 = 1/0 =undefined

If a+b = c which of the following statements is true?
b-c=a
a-c=b
c-a=b
c+b= a
Answer:
c-a=B
Step-by-step explanation:
if A+B=c then you subtract a from c and you get b
Answer:
C. c - a = b
Step-by-step explanation:
a + b = c
There are many ways to rearrange this equation. This can be done through addition and subtraction.
First, let's handle a. a is positive; therefore, we should subtract it.
a + b = c
b = c - a
Next, let's handle b. b is also positive; therefore, we should subtract it.
a + b = c
a = c - b
Finally, we will handle c. c is once again positive; therefore we should subtract it. However, it is the only variable on the right side, which would leave 0. This is not an option, so we will not look at this.
From our options, we can see that we have produced: b = c - a
This is an option, which has been written as c - a = b.
Therefore, your answer is C. c - a = b
