You are right about the domain.
Answer:
10:1
90 red counters
30 blue
1/3 of 90 =30
80% of 30 =24
90-30 =60 remaining red counters
30-24 =6 remaining blue counters
= 60:6 simplest form is 10:1
<span>Each smaller donation was for $20
The largest donation was $15 greater than the smaller donation.
First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios.
5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35
So the 2 smaller donations were $20 each, and the largest donation was for $35.
The largest donation was $35 - $20 = $15 larger than one of the smaller donations.</span>
Answer:
Percent of change in population is
%
Step-by-step explanation:
Given population of Boston is
measured in year
.
And population of Boston in year
is
.
We need to find percent of change in population.
So, percent change
%
Here old population is
and new population is 
Plugging these value in formula we get,
Percent change 
Rounding to nearest tenth 2.6%
Answer:
The value of t is 41
Step-by-step explanation:
<em>The figure is 5 sided polygon.</em>
The sum of interior angles of 'n' sided polygon is given by,
= 
here, n=5,
thus, 
All the given angles have linear pair in the polygon.


Thus, t = 41
