0.25 inches represents 1 mile
----------------------------------------------
Find 1 inch:
----------------------------------------------
1 inch represents 1 ÷ 0.25 miles
1 inch represents 4 miles
----------------------------------------------
Find 3.75 inches:
----------------------------------------------
1 inch represents 4 miles
3.75 inches represent 4 x 3.75 miles
3.75 inches represent 15 miles
----------------------------------------------
Find 2.25 inches:
----------------------------------------------
1 inch represents 4 miles
2.25 inches represent 4 x 2.25 miles
2.25 inches represent 9 miles
----------------------------------------------
Find Area:
----------------------------------------------
Area = Length x Width
Area = 15 x 9
Area = 135 miles²

Answer:
Option A.
Step-by-step explanation:
Clarissa needs a $2,500 loan in order to buy a car.
There are 4 options of loan we will calculate all the options that pay the least amount of interest.
To calculate the interest we will use this formula :
Where P = Principal amount
R = rate of interest
T = time in years
A) Principal 2,500 interest 4.75% and time 18 months (1.5 years)
= $178.125
B) Principal 2,500 interest 4% and time 30 months (2.5 years)
= $250
C) Principal 2,500 interest 4.25% and time 24 months (2 years)
= $212.50
D) Principal 2,500 interest 4.50% and time 36 months (3 years)
= $337.50
The least amount of interest would be in option A.
Answer:
The confidence interval is (0.81, 0.87).
Step-by-step explanation:
There's 90% confidence that population proportion is within the interval obtained from the following formula:
Knowing that the sample size, 
we obtain the proportion of people from the sample who leave one space after a period as 
.
We then look for the critical value:
Now we can replace in the formula to obtain the confidence interval:
Therefore we can say that there's 90% probability that the population proportion of people who leave one space after a period lies between the values (0.8137; 0.8663).
Answer: Gerry has 25 more basketball cards than baseball cards.
Step-by-step explanation:
The total number of sports trading cards that Gerry has is 50.
Of those cards one fifth of them are baseball cards. It means that the number of baseball cards that he has is
1/5 × 50 = 10
one tenth of them are football cards. It means that the number of football cards that he has is
1/10 × 50 = 5
The rest are basketball cards. It means that the number of basketball cards that he has is
50 - (10 + 5) = 35 basketball cards
The difference between the number of basketball and baseball cards that he has is
35 - 10 = 25
