Answer:

<h2>B. y = -1.5x + 350</h2>

Step-by-step explanation:

Givens

  • Frederick earns $10 per hour at the grocery store.
  • He earns $8.50 per hour mowing lawns.
  • He worked 35 hours last week.

x represents hours mowing lawns, which make him earn $8.5 each.

y represents the total earnings, mowing lawns plus grocery store.

Now, we know that he worked 35 hours in total. So, if he worked x mowing lawns, then he worked 35-x hours in the grocery store, which represents +$10 per hour. So, this situation can be expressed as

y=8.50x+10(35-x)

Then, we solve the operations

y=8.50x+10(35-x)\\y=8.50x+350-10x\\y=-1.5x+350

Therefore, the right choice is B. y = -1.5x + 350

Let t be time in seconds and let r(t) be the rate, in gallons per second, that water enters a reservoir: r(t)=700−40t. a) For 0≤
Flura [38]
What you don't want is the value of r(t) becoming negative. Surely that would represent water escaping the reservoir.

How big can (t) get before water actually starts escaping the reservoir?

Essentially, to figure this out r(t) would have to be equal to 0. 

700 - 40t = 0

40t=700

t=700/40=17.5

So the first answer is 17.5 seconds. After this amount of time has elapsed the reservoir will start to lose water as r(t) would become negative.

---------------

The reservoir had the least amount of water in it before it was being filled. That was when t=0. The volume of water in the reservoir wasn't negatively impacted as not enough water had escaped it during the 17.5 to 30 second period.

Arlecino [84]

Answer:

Let v = ml of 100% vinegar

Then 150-v = ml of dressing

v  + .05(150-v) = .24(150)

v + 7.5 - .05v = 36

.95v = 28.5

v = 28.5/.95

v = 30 ml of vinegar

dressing = 150-30 = 120 ml

Answer:

C. 0 6 10

Step-by-Step-Explanation:

the number on the left of the indicated operation is the original set

the number '2' next to R shows that you need to multiply certain numbers by 2

the subscript on the R's shows which row the multiplication needs to be done on...

so in this case, leave the second row alone: 1  3  4

but multiply the first row by 2: 0  6  10
