August is making dinner for 8 people. She opens 7 cans of soup. Each can is 16 ounces. If everyone gets the same amount of soup, how much soup will each person get?
This is for my sister, and her teacher said that the correct answer is 3.5 ounces. If anyone gets this answer, please show how you got the answer...thank you!
Answer:
14oz soup/ person
Step-by-step explanation:
the answer would be 14oz of soup/person
multiply 7 (cans of soup) by 16 (oz per can)
7*16=112
divide 112 (oz of soup total) by 8 (number of people feeding)
112/8=14

In many parades, flowers are used to decorate the floats. The table below shows the number of flowers used in each row of a parade float.
1
54
2
58
3
62
4
66
Which equation best describes these data?
Answer: C. n = 4r + 50
Step-by-step explanation:
The equation is in the form: y =mx + c
y is the number of flowers used.
x is the row number.
Solving for m. Pick any two points. (1, 54) and (2, 58)
m = (Y₂ - Y₁) / (X₂ - X₁)
= (58 - 54) / (2 - 1)
= 4
Solving for c. Use a point to fill up the formula and find c; (1, 54)
y = mx + c
54 = 4 * 1 + c
c = 54 - 4
c = 50
Formula will therefore be;
y = 4x + 50
or;
n = 4r + 50

Discount selling price= selling price*(1 - discount rate)
Discount selling price= 230* (1-0.25)
Discount selling price= $172.5

Answer: B
Step-by-step explanation:
There are several ways to solve this problem, but I think the easiest way is just to find the mean.
There are 12 total data points, and adding them all up you get 266.
mean = 266/12 = 22.167
The line in the middle of the box plot represents the mean, so the answer must be B.

Christopher is hanging Christmas lights along the perimeter of his house by using his 15 foot ladder. The base of the ladder is placed 4 feet away from the base of his house. How far up the house does his ladder reach?
Answer:
14.45 feet
Step-by-step explanation:
The set up is a right angled triangle;
The length of the ladder = hypotenuse = 15foot
The base of the ladder is the adjacent = 4feet
The height of th house is the opposite = x
Using the pythagoras theorem;
hyp² = opp² + adj²
15² = opp²+4²
opp² = 15²- 4²
opp² = 225 - 16
opp² = 209
opp = 14.45feet
Hence the ladder reaches 14.45 feet up the house
Which line is parallel to the line given y=- 4/3x+1

A steel ball is traveling through water with a speed of x meters per second, where x is positive. The drag force, F, in newtons, N, is: F = 0.5 + 0.004(x + 50)(x-2.5). At what speed in meters per second does the ball have a force of 0.5 N, on it?
Answer:
x = 2.5m/s.
Step-by-step explanation:
Given that F = 0.5 + 0.004(x + 50)(x – 2.5), where x is the speed in m/s and F is the force in N. To know the speed, x, with F = 0.5N, we have:
0.5 = 0.5 + 0.004(x + 50)(x – 2.5)
This gives
0.004(x + 50)(x – 2.5) = 0 (after adding –0.5 to both sides).
For the multiplication to be 0, (x + 50)(x – 2.5) = 0 because 0.004 is not equal to 0.
Hence
x = –50 or x = 2.5
Since it is said from the question that x is positive then x = 2.5m/s.

Raju took 5/6 h to complete his mathematics homework. He took 1/5 h less to complete his english homework. how many hours did raju take to complete his english homework? what was the total time spent by raju on his homework?
Answer:
English homework = 19/30h or 38 minutes
Total time spent = 22/15h or 88 minutes
Step-by-step explanation:
Mathematics homework = 5/6h
= 5/6 × 60
= 300/6
= 50 minutes
He took 1/5 h less to complete his english homework.
English = 5/6h - 1/5h
= 25h-6h/30
= 19/30h
= 19/30 × 60
= 1,140/30
= 38 minutes
English homework = 19/30h or 38 minutes
Total time spent on his homework = mathematics homework + English homework
= 5/6h + 19/30h
= 25h+19h/30
= 44/30h
= 22/15h
= 22/15 × 60
= 1,320 / 15
= 88 minutes
