Louisa’s savings change by -$6 each time she goes bowling. In all, it changed by -$66 during the summer. How many times did she
Sav [38]

Answer: She went 11 times during the summer.

Step-by-step explanation:

If Louisa's savings change by -6 each time she goes bowling and it went to -66, that means that Louisa went another 11 times.

\frac{1}{11}

So therefore your answer would be 11.

A large mixing tank currently contains 225 225 gallons of water, into which 5 5 pounds of sugar have been mixed. A tap will open
kkurt [141]

Answer: Hello mate!

you put every number twice, I will consider that in this problem we have:

225 gallons of water initial with 5 pounds of sugar. then each minute you add 20 gallons of water and 4 pounds of sugar.

the concentration is defined as pounds of sugar divided by the gallons of water. The gallons of water are 225 initially and 20 per minute, this is written as 225 + 20tt, where t is the minutes. The pounds of sugar is 5 + 4 per minute, then this can be written as 5 + 4t

C(t) = \frac{5 + 4t}{225 + 20t}

this is the equation that describes the concentration in pounder per gallon after t minutes.

A phone company offers two monthly plans. Plan A costs $16
Trava [24]
We can write two equations for this. x = each minute of calls

Plan A = .1x + 16
Plan B = .14x

Make the two equations equal each other, so we can find when they are the same.

.1x + 16 = .14x

Subtract .1x from both sides

16 = 0.04x

Divide by 0.04 to get x by itself

400 = x.

Earlier, we set x as each minute of calls. This means that after 400 calls, Plan A and Plan B will cost the same.

To find the cost, substitute 400 into both equations by themselves.

Plan A cost = .1x + 16
Plan A cost = .1(400) + 16
Plan A cost = 40 + 16
Plan A cost = $56

Plan B cost = .14x
Plan B cost = .14(400)
Plan B cost =  $56

Final answer: After 400 calls, Plan A and Plan B will both cost $56.
