Answer: The most time you can be online on the seventh day is 45 hours.

Step-by-step explanation:

Hi, to answer this question we have to obtain the whole week number by multiplying the mean (60) by the seven days of the week:

Mathematically speaking:

  • 60 x 7 = 420 hours

Now, we have to sum the amount of hours online of each day:

  • 70+60+65+40+78+62 =375

Finally, we have to subtract that number to the whole week number:

  • 420 -375 =45 hours

The most time you can be online on the seventh day is 45 hours.

60*7=420
70+60+65+40+78+62=375
420-375=45
You can only be online for 45 minutes on the seventh day to reach your goal

aleksandr82 [10.1K]
15.25 divided by 100= 0.1525 times 15 = 2.2875 then round to $2.29 (2.29 is the tip) 2.29 + 15.25 = $17.54 would be the total cost!

SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t
lara [203]

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

h= -16(t-1.5)(t+1)

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in h= -16(t-1.5)(t+1)

0= -16(t-1.5)(t+1)

Divide both sides by -16

\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}

\frac{0}{-16} =(t-1.5)(t+1)

0 =(t-1.5)(t+1)

(t-1.5)(t+1)=0

Split

t - 1.5 = 0 or t + 1 = 0

Solve for t

t = 1.5 or t = -1

But time (t) can not be negative.

So:

t = 1.5

Hence, the diver will hit the water at 1.5 seconds
