Answer:
61 Students.
Step-by-step explanation:
So you need to find 20% of 305. You can do this by dividing by 5.
305 divided by 5 equals 61.

Answer:
Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.
Step-by-step explanation:
A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft) 20 30 50 75 80 120 150 ?
Which statement correctly explains how to find the distance traveled after 150 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. Find the ratio of hops to distance traveled (1:1.5), then multiply 150 by 1.5. Find the ratio of hops to distance traveled (1:1.5), then divide 150 by 1.5.
Solution:
The table is:
No. of hops Distance traveled
20 30
50 75
80 120
150 ?
From the table, for every 30 increase in the number of hops, the distance travelled increase by 45 feet
Find the slope of the line:
m = (y2-y1) / (x2-x1)
m=slope of the line
y2-y1 = change in distance travelled
x-2 - x1 = Change in number of hops
m = (y2-y1) / (x2-x1)
m = (75-30) / (50-20)
=45 / 30
m = 1.5
Then, the line is:
y = 1.5x
We substitute x = 150
y = 1.5x
y = 1.5 × 150
y = 225
1) The larger number is 33.
2) Joan weighs 47.5 kg, and Annie weighs 44.5 kg.
3) Ronnie walks at a rate of 4 km/h, while Margie walks at a rate of 2 km/h.
4) It takes 3 hours for Lea to do the same task working alone.
5) Katie is 5 years old and Rico is 1 year old.
To solve each problem, the following calculations must be done:
1)
(54 - 12) / 2 = X
42 / 2 = X
21 = X
21 + 12 = 33
33 + 21 = 54
2)
(92 - 3) / 2 = X
89 / 2 = X
44.5 = X
44.5 + 3 = 47.5
44.5 + 47.5 = 92
3)
1000 / 3 x 2 = 666.666
0.666 x 6 = 3.999
0.333 x 6 = 1.999
4)
1/5 + 1/X = 1/2
10/5 + 10/X = 10/2
2 + X = 5
X = 5 - 2
X = 3
5)
5 /// 1
8 /// 4
