Answer:
7/10
Step-by-step explanation:
Use the butterfly method:
3/5 7/10
multiply the denominator and numerator to each other sides:
3 * 10 = 30
5 * 7 = 35
35 > 30
35 belongs to 7/10 so:
7/10 is greater
Answer:
The linear model means that there is a uniform increase and in this case of US population from 92 million people in 1910 to 250 million people in 1990
.
This means an increase of 250
−
92
=
158 million in 1990
-1910
=
80 years or

=
1.975 million per year and in x years it will become 92

The exponential model means that there is a uniform proportional increase i.e. say p
% every year and in this case of US population from 92 million people in 1910 to 250 million people in 1990
.
This means an increase of 250
−
92
=

, which gives population in a year y and this appears as

Hope this helps
The y intercept is 3 because the line intercepts the y axis at 3.

Answer:
There is a 4% decrease
Step-by-Step:
if the previous total was 50, then each animal represents 2%. 50*2=100. if you are increasing the dogs by 20% of 20, then you are increasing them by 4 equaling out to 24 dogs. If your decreasing the cats by 20% of 30, then you are decreasing them by 6 equaling out to 24 cats. The new total of animals is now 48. Seeing how each animal still represent 2%, the new percentage is 96%. Subtracting the previous percentage from the new percentage gives a 4% difference.
50 * 2 = 100%
20 * 1.2 = 24
20 * .8 = 24
24 + 24 = 48
48 * 2 = 96%
100% - 96% = 4%
The answer is one because...
3+10÷5-4
3+2−4
5−4=1
