Kara downloaded 384 selfies from her cell phone to her laptop. These selfies took up 768 megabytes of space on her laptop. Each selfie took up the same amount of space. How many megabytes do 40 selfies take up? n
Since 384 selfies took up 768 megabytes of space, each selfie takes up 768/384=<<768/384=2>>2 megabytes.
Thus, 40 selfies would take up 40*2= <<40*2=80>>80 megabytes. Answer: \boxed{80}.
Carlos traveled at an average speed of 70 miles per hour for 2.5 hours and then traveled at an average speed of 80 miles per hour for 3.5 hours. What was the total distance in miles that Carlos traveled during that time?
Responses
A 490490
B 455455
C 385385
D 495
To find the total distance traveled, we need to find the distance traveled at each speed and then add them together.
Distance traveled at 70 miles per hour for 2.5 hours = 70 * 2.5 = 175 miles
Distance traveled at 80 miles per hour for 3.5 hours = 80 * 3.5 = 280 miles
Total distance traveled = 175 + 280 = 455 miles.
Therefore, the correct answer is B) 455.
An XBOX 360 regularly sells for $399. It is on sale for 20% off. What is the sale price of the XBOX 360?
To calculate the sale price of the Xbox 360, we need to find 20% of $399 and subtract it from the original price:
20% of $399 = (20/100) * $399 = $79.80
Subtracting $79.80 from $399 gives us the sale price:
$399 - $79.80 = $319.20
Therefore, the sale price of the Xbox 360 is $319.20.
The ratio of boys to girls in Mrs. Reiter’s music class is 2 to 3. There are 24 girls in the class. ?
?What is the total number of students in Mrs. Reiter’s music class?
Responses
To find the total number of students in Mrs. Reiter's music class, we can use the ratio of boys to girls.
The ratio of boys to girls is 2 to 3, which means for every 2 boys, there are 3 girls.
Given that there are 24 girls in the class, we can calculate the number of boys by multiplying 24 by (2/3):
Number of boys = 24 * (2/3) = 16
Therefore, the total number of students in Mrs. Reiter's music class is 16 + 24 = 40.
So the correct answer is: 40.
Madison bought an empty lot for $2,000 and later sold it for a 25% profit. How much did Madison sell the lot for?
To calculate the selling price of the lot, we need to add the 25% profit to the original cost of $2,000.
Profit = 25% of $2,000 = (25/100) * $2,000 = $500
Selling price = Original cost + Profit = $2,000 + $500 = $2,500
Therefore, Madison sold the lot for $2,500.
