(out loud) Find the percentages. 15m is what percent of 60m; 3m; 30m; 1.5 km?
1 answer:
Answer: 15meter is 25% of 60m
15m is 500% of 3m
15m is 50% of 30m
15m is 1% of 1.5km.
Step-by-step explanation:
Given: 15m is what percentage of 60m; 3m; 30m; 1.5km
To find: Find the percentage.
Formula used: 1 kilometer=1000meter.
Explanation:
Let X percentage of 60m =15meter
So, X% of 60m =15m
= 15m
Multiply both side by 100.
60X = 1500m
On dividing both side by 60
X = 25%
Let X percentage of 3m =15meter
So, X% of 3m =15m
= 15m
Multiply both side by 100.
3X = 1500m
On dividing both side by 3
X = 500%
Let X percentage of 30m =15meter
So, X% of 30m =15m
= 15m
Multiply both side by 100.
30X = 1500m
On dividing both side by 30
X = 50%
Let X percentage of 1.5km =15meter
Convert kilometer into meter by above formula (1.5km=1500meter)
So, X% of 1500m =15m
= 15m
Multiply both side by 100.
1500X = 1500m
On dividing both side by 1500
X = 1%
Therefore , 15meter is 25% of 60m
15m is 500% of 3m
15m is 50% of 30m
15m is 1% of 1.5km.

Answer: (a) The slope of the line is 5 and the y-intercept is (0,10). (b) The rate of change is 5 and the initial amount is 10.
Explanation:
The given equation is,
.... (1)
(a)
The slope intercept form of the a line is,
.... (2)
Where, m is slope and (0,b) is y-intercept.
On comparing (1) and (2) we get,
Therefore, the slope is 5 and the y-intercept is (0,10).
(b)
The rate of change is also known as slope therefore the rate of change is 5.
To find the initial amount put x=0 in the given equation.
Therefore, the initial value is 10.
The rate of change represents the number of baskets of berries the workers picked increased by 5 units per unit of time.
The initial amount shows the number of baskets of berries the workers picked before the workers starts harvesting.
(c)The graph is shown below.
Since x represents the time in hours, therefore x is always greater that or equal to 0.
