The answer for this question is b
Answer:
- Hence, 75.52 percent of the u.s. population had internet access in 2005.
- After 25 years or in the year 2015 89% have internet access.
Step-by-step explanation:
the percent p of the u.s. population with internet access is given by:
25 p-34 t=1378
where t is the number of years after 1990.
- We are asked to find what percent of the u.s. population had internet access in 2005 i.e. we need to find the value of p after 15 years i.e. t=15.
⇒ 25p-34×(15)=1378
⇒ 25p-510=1378
⇒ 25p=1378+510
⇒ 25p=1888
⇒ p=75.52
Hence, 75.52 percent of the u.s. population had internet access in 2005.
- Next we are asked to find in what year will 89% have internet access?
i.e. we have to find the value of t when we are given p=89
⇒ 25×89-34t=1378
⇒ 2225-34t=1378
⇒ 2225-1378=34t
⇒ 847=34t
⇒ or 34t=847
⇒ t=24.9112≈25
Hence after 25 years 89% will have internet access.
i.e. in the year 2015 89% will have internet access.
The chain made 145 times more money than the single store.
To find this answer first find the amount of money both made and divide the chain amount by the super store amount to get the final answer.

Clint randomly picks a card from a collection of eight hearts and two spades. Which situation can he represent with this simulation?
I think the correct answer for this question is :
A) randomly picking a napkin from a collection of four white napkins and one blue one
As you can see the probabilities are the same and that's how you figure your answer out.
Hope this helps!
Answer:
A reflection and a dialation
Step-by-step explanation:
- Reflection is when you flip a figure over a line.
- Rotation is when you rotate a figure a certain degree around a point.
- Dilation is when you enlarge or reduce a figure.
In this case a rotation is not nessasary, so I would suggest a reflection in the y-axis and a dialation to shrink the triangle to A'B'C'
So for the transformations that could have occurred to map ABC to A'B'C' you should choose the answer
a reflection and a dialation
