Faye used a stopwatch to find that in 352 minutes, she read 88 pages.Measured in seconds, how long did it take Faye to read 1 page?

Answers

Answer 1
Answer: 88 pages = 352 minutes
1 page = 352/88 = 4 minutes 
4 minutes = 240 seconds. 

For Faye to read 1 page, it took her 240 seconds

A student answered 46 problems on the test correctly and received a grade of 88%. how many problems were on the test if all problems we wear the same number of points?

Answers

The answer is 52 questions
so to find percentages we do the part over the whole.   So in this equations we do

(answered correctly)/(total number of questions) * 100=grade

answered correctly = 46 
Total number problems = x
where x is the number we don't know 
and 
grade is 88

(46)/(x) = .88 

multiply both sides by x 

we get 

46 = .88x

we just need to simplify
46/.88 = x
52.27 = x  


How many gallons of water will it take to fill a tank measuring 8' long 28" wide and 3' deep

Answers

You're looking for the volume function here.  V=LWH

In this case the length is 8 feet
L=8
Width is 28 inches, and since there's twelve inches in a foot, it's 28/12 feet
W=28/12=2(1)/(3)
Height, or in this case depth, is 3 feet
H=3

V=LWH
V=(8)(2(1)/(3))(3)
V=56ft
^(3)

Now you know how many cubic feet are in your tank.  There are just around 7.5 gallons in a cubic foot.  An estimated answer then would be the volume times 7.5

56
·7.5=420

There's an estimated answer.  If you need exact EXACT, then using the exact amounts and everything the answer comes out to 418.909 gallons.

What is the factored form of the expression? 3x 2 + 8x – 16A. (3x + 4)(x – 4)
B. (3x + 4)(x + 4)
C. (3x – 4)(x – 4)
D. (3x – 4)(x + 4)

Answers

The correct answer is D. (3x-4)(x+4).  

Answer:

The factored form of the expression  3x + 8x – 16 is (3x -4) (x + 4)  .

Option (D) is correct.

Step-by-step explanation:

As the expression given in the question be.

3x^(2) +8x -16 = 0

3x^(2) +12x - 4x -16 = 0

3x (x + 4) - 4 (x +4) = 0

(3x -4) (x + 4)  = 0

Therefore the factored form of the expression  3x + 8x – 16 is (3x -4) (x + 4)  .

Option (D) is correct.

Ohama is landing a plane on the runway. He's trying to decide where he should deploy the plane's landing gear so that the plane comes to a stop exactly at the end of the runway. The runway is 600 yards long, and the plane will travel half the distance with the landing gear than without the landing gear. Where should he deploy the landing gear ?

Answers

Answer:

Let's define:

A = distance traveled before deploying the landing gear

B = distance traveled after deploying the landing gear.

We must have that the sum of those two distances must be equal to 600 yards.

A + B = 600 yd.

And we know that:

" the plane will travel half the distance with the landing gear than without the landing gear."

Then we have that:

B = A/2.

Now we can replace this last equation in the first one:

A  + B = 600yd

A + A/2 = 600yd.

(3/2)*A = 600yd.

A = (2/3)*600yd = 400yd.

Ohama should deploy the landing gear 400 yd into the runway.

If h(x) = x − 1 and j(x) = −4x, solve h[j(5)] and select the correct answer below.−21
−20
−19
−16

Answers

Answer:

Option A is correct

h[j(5)] = -21

Step-by-step explanation:

Given the functions:

h(x) = x-1 and

j(x) = -4x

Find the value of h[j(5)]

h[j(x)]

h[-4x]

Replace x with -4x in h(x) we have;

h[j(x)] = -4x-1

Substitute x = 5 we have;

h[j(5)] = -4(5)-1

h[j(5)] = -20-1=-21

Therefore, the value of h[j(5)] is, -21

-21. J(x)= -4(5)= -20 ; H[J(5)]= -20-1 = -21
