Answer: The calculation is correct.
Step-by-step explanation:
If Hernando ate 2/8 of a pizza for a dinner, the remaining pizza will be:
= 1 - 2/8
= 6/8
If he gave his 6 friends the rest of the pizza and told them to share it equally, each person will get:
= 6/8 ÷ 6
= 6/8 × 1/6
= 1/8
Each person will get 1/8 each
Since he also concluded that each person received 1/8 of the whole pizza, Hernandos calculations are correct

John takes 15 minutes to get to school. The bell rings at 9:00a.m. John wants to get there 5 minutes before the-bell. At what time should John leave home?
Answer:
8:40 a.m.
Step-by-step explanation:
Let's start by finding the time John should arrive at school.
9:00 a.m. - 5 minutes = 8:60 a.m. - 5 minutes = 8:55 a.m.
Note that there are 60 minutes in an hour
Now, we find the time he should leave home...
8:55 a.m. - 15 min = 8:40 a.m.
Therefore John should leave at 8:40 a.m.
Another way to solve this problem:
John needs to leave home in "x" minutes before 9:00 a.m. to arrive when the bell rings (9:00 a.m.). To find "x", we need to add 15 and 5 to get:
15 min + 5 min = 20 min.
Therefore he must arrive 20 minutes before 9:00 a.m.
9:00 a.m. - 20 min = 8:40 a.m.
Therefore John should leave at 8:40 a.m.

Its three.
Step-by-step explanation:
When you see a sequence such as this one, it is called an arithmetic sequence. You must add to get to the next term. So, the amount of numbers that you need to get from 3 to 6, 6 to 9, and 9 to 12 would be the common difference, so the common difference in this specific sequence would be 3.
A road is 400m long and 36% of it is damaged by flood.(a) How many meters are damaged? (b)what length of road of road is not damaged?
Answer:
it is 1111.1
Step-by-step explanation:
divide 400 by 36 percent
Answer:
144 meters are damaged, 256 meters are undamaged
Step-by-step explanation:
400m = 100%
Xm = 36%
Xm= (400m)(36%)/100%
Xm=14400 meters/100%
Xm= 144meters
To know how much of the road is undamaged:
400m-144m= 256m

Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well? y [ Select ] [ Select ] = [ Select ] (x - [ Select ] )
Answer:
Point slope form is y+1=4(x-1)
Step-by-step explanation:
She lifts water at a rate of 4ft/s.
After 1 second, the bucket is 1 feet below the top of the well. So, point form of this would be (1,-1).
Here, let's use the slope m= rate = 4 ft/s
Point as (1,-1)
So, y-(-1)= 4(x-1)
Simplify, it gives
y+1= 4(x-1)

The length of a rectangular table is represented by the function L(x) = 4x. The width of the table is represented by the function W(x) = 3x2 − 5x + 6. What is the area of the table in terms of x? (1 point)
(L • W)(x) = 7x3 − x2 + 10x
(L • W)(x) = 12x2 − 20x + 24
(L • W)(x) = 12x3 + 20x2 + 24x
(L • W)(x) = 12x3 − 20x2 + 24x
Answer:
(L • W)(x) = 12x^3 − 20x^2 + 24x (the last option)
Step-by-step explanation:
It's very simple actually. To find an area of a rectangle, all we have to do is multiply its two sides. We are given the length and the width of the rectangle - its sides. All we have to do is simply multiply them:
Area = L(x) * W(x)
L(x) = 4x
W(x) = 3x^2 - 5x + 6
Therefore the area is equal to:
(4x) * (3x^2 - 5x + 6) =
= 4x * 3x^2 - 4x * 5x + 6 * 4x =
= 12x^3 - 20x^2 + 24x
And there's your answer, option D, or 4 or whatever you call the last one.
Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enough yarn to put fringe around the blanket, as long as the perimeter of the blanket is no more than 180 inches. The system of inequalities shown represents the width of the blanket in inches, w, and the length in inches, l.
w ≥ 0.5l
2l + 2w ≤ 180
What is the maximum length possible for her blanket?
30 inches
45 inches
60 inches
90 inches
Answer:
C 60 inches
Step-by-step -
60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.

C
