Answer:

-7k = -45.5

Explanation:

You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:

-3(6.5) = -19.5

-1 + 6.5 = 5.5

-7(6.5) = -45.5

-2 + 6.5 = 4.5

So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.

-7k=-8.5 since if you were to plug the number Back in (-7k(6.5)=7.5 the equation is correct

Answer:

Volume = 10562.96  cu ft

10.56 hr. to drain all the water

Step-by-step explanation:

V = 1/3Bh        B = area of the base           h = height

The base is a circle, so B = \pi r^{2}

V = \frac{1}{3} (3.14) (29^{2})(12) = 10562.96  cu ft

10562.96/1000  = 10.56 hr.

How yall can help me out
Maslowich

Answer: (b)

Step-by-step explanation:

2√12 x 3√5 (numerator)

= (2x3)(√12x √5)

= 6√60

√30x √36

= √30 x 6

=6√30

Now,

6√60/6√30

We can cancel 6

So, it's √60/√30

= √60/30

= √ 2= 1.41 approx

Hope it helps!
