A class has 30-40 students. Each boy in the class bring 15 chocolate bars for a class party to celebrate Teacher's Day. The chocolate bars are shared equally among the 20 girls of the class and their form teacher with no leftovers.
(i) How many students are there in the class?
Detailed steps please!

Answers

9514 1404 393

Answer:

Step-by-step explanation:

In order to divide some multiple of 15 chocolate bars evenly by 21, the number of bars must be a multiple of the LCM of 15 and 21, which is 105. That number is 7 times 15, indicating the number of boys in the class must be a multiple of 7. The only number between 30-20 = 10 and 40-20 = 20 that is a multiple of 7 is 14.

There must be 14 boys in the class, so 34 students in total.

The boys brought a total of 210 chocolate bars, so each girl and the teacher received 10 of them.

Macy has bought 812 bananas. Jake has bought 83% of Macy's bananas. Karl bought three times the amount of Jake's amount at a local grocery store. Gary then proceeded to buy 29% of Karl's bananas. How much bananas does Gary have in total?

Answers

Answer:

586 bananas

Step-by-step explanation:

Macy - 812 bananas

Jake - (812 x 0.83) = 673.96 bananas

Karl - (673.96 x 3) = 2021.88 bananas

Gary - (2021.88 x 0.29) = 586.3452 bananas. The answer gets rounded down to 586 bananas because he can't have part of a banana

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she started filling it. Time (minutes) 1, 1.5, 2 Water (gallons) 16.50, 24.75,33. Now find the constant of proportionality (in gallons per minute) for the second and third rows of the table. Show your work.

Answers

Answer:

K= 16.5 gallons per minute

Step-by-step explanation:

Time t (minutes) Water g (gallons)

For t= 1, g= 16.50,

for t= 1.5 ,g= 24.75

For t= 2,g= 33

Let the function be

Gallons g= k(time t)

Where k is the constant of proportionality

16.5= k(1)for when t= 1

24.75= k(1.5) ..for when t= 1.5

Solving gives

8.25=k(0.5)

8.25/0.5= k.

16.5 = k

K= 16.5 gallons per minute

Which equation represents the depth of the drill in meters, y, after x hours of drilling?A line passes through the origin and (4, 5). Which point is also on the line?

Answers

Answer:
6y = x
Step-by-step explanation:
All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.
y = distance in meters
x = time
12y = 2x
12y/2 = 2x/2
6y = x
30y = 5x
30y/5 = 5x/5
6y = x

Angle Y is a right angle, so it’s 90 degrees. Angle W is 2x, since it’s opposite angles on a single line intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:

X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
