Mike observed that 75% of the students of a school liked skating. If 35 students of the school did not like skating, the number of students who liked skating was ______. (only put numeric values, no other symbols)

Answers

100-75=25% did not like
25%=35 students how about 75%
75 x 35 divided by 25=105 students 
105
100-75=25%
25%=35 students but you have 75%
so 75*30divided by 25=90 students

The table shows the number of candies packed by Machine J. The equation shows the number of candies packed by Machine K. In both representations, x is a measure of the number of minutes and y is a measure of the number of candies packed. Machine J Candy Packing
x
(minutes) y
(candies)
3 90
6 180
9 270
12 360


Machine K: y = 26x

How many more candies could machine J pack than machine K in 11 minutes?
30
44
90
330

Answers

To find out the answer, treat both machines as lines. The answer can be found when you have equations for each machine. The first step of that would be to make an equation for "line" J, so find the slope using two sets of its given coordinates, I'll use (3,90) and (6,180).

(y_2 - y_1)/(x_2 - x_1)   Substitute in the x and y values
(180 - 90)/(6 - 3)   Subtract
(90)/(3)   Divide
30

Now that you know 30 is the slope, you can plug that and one set of coordinates, I'll use (3,90) into point-slope form.

y - y_1 = m(x - x_1)   Substitute in your x and y coordinates and slope
  y - 90 = 30(x - 3)     Use the Distributive Property
  y - 90 = 30x - 90      Add 90 to both sides
         y = 30x   

Now you have the equations for both machines. You want to find out how many candies each machine packages in 11 minutes, and x represent minutes, so plug 11 into the x value for both equations.

Machine J

y = 30x         Substitute
y = 30 (11)   Multiply
y = 330
 
Machine J packs 330 candies in 11 minutes.

Machine K

y = 26x         Substitute
y = 26 (11)    Multiply
y = 286

Machine K packs 286 candies in 11 minutes.

Finally, to find out how many more candies Machine J packs than Machine K, subtract the two values.

330 - 286 = 44

Machine J can pack 44 more candies than Machine K in 11 minutes.

Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2

Answers

Common question that is always asked : "Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2".Well let me show you how it works.=> 3 of 1/6 to makw 1/2First, i'll show you the 3 copies of 1/6 added together=> 1/6 + 1/6 + 1/6 = 3/6, since they already have the same denominator, we directly added it.=> now, notice that 3/6 can be divided with or simplified=> 3/6 divided by 3 = 1/2Hence, that's how it becomes 1/2

of a pizza. Which shows a correct way to find the weight of the whole pizza?

Answers

Answer: top right

Step-by-step explanation: in order to seperate p, we need to multiply each side by 6, as this will make the right side just p. Then, since we mutiplied by 6 on the right side, we multiply by 6 on the left side too, so we get 5.5*6

What is 34% written as a ratio?

Answers

The ratio of 34% is 17:50.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

34%

This can be written as,

34/100

= 17/50

This can be written as a ratio,

= 17:50

Thus,

The ratio is 17:50.
