Answer:

The water amount will be equal at 19.5 minutes

Step-by-step explanation:

Here, we want to find the value of t when the water level in both tanks will be equal

We simply proceed to equate both ;

That will be;

30t + 25 = -20t + 1000

30t + 20t = 1000-25

50t = 975

t = 975/50

t = 19.5 minutes

1,6, 11, 16 .. Find the 12th term of this Ap.?
Nonamiya [84]

Answer: 61

Step-by-step explanation: It's going up by five each time. We can write a function...

f(x)=5x+1

Starting Value: 1

Rate of Change: 5

x=12

f(12)=5(12)+1

5 times 12 is 60

60 + 1= 61

Therefore the answer is 61

Rewrite the expression with the given base.<br><br> 125^2x with a base of 5
jasenka [17]
Okay so you have to start by working out how many times you multiply 5 by itself to get 125. 

5x5x5=125

therefore: (5^3)^2x) is the answer:)

4.5, 9, 13.5, 18...
Sladkaya [172]

Answer:

a) Arithmetic

b) 22.5

c) 4.5

d) a_n = 4.5 + 4.5(n - 1)

e) a_15 = 67.5

Step-by-step explanation:

a) Subtract one term by the term right before it, and the difference will be the common difference.

9 - 4.5 = 4.5

13.5 - 9 = 4.5

18 - 13.5 = 4.5

Therefore, the common difference is 4.5.

b) Since the common difference is 4.5, add 4.5 to the 18 (which was the last value given). The result is 22.5.

c) We have already figured out that the common difference is 4.5.

d) The explicit formula would be a_n = a1 + d(n - 1). The first term is 4.5 and d is also 4.5, so the explicit formula is a_n = 4.5 + 4.5(n-1).

e) Plug 15 into our explicit formula for n. a_15 = 4.5 + 4.5(14). The result is 67.5.

dusya [7]

Answer:

\frac{1}{8} chance or 12.5% chance

Step-by-step explanation:

2 male <em>percussionists</em>

2 female <em>percussionists</em>

3 male <em>woodwinds</em>

<u>2 </u><u>female</u><u> </u><u><em>woodwinds</em></u>

4 male <em>brass players</em>

3 female <em>brass players</em>

We're looking for a female <em>woodwind. </em>Now there is only 2 of them so we get the female woodwinds out of all the jazz band members or \frac{2}{16} or \frac{1}{8} or 12.5% chance.
