To predict how many eye glasses the doctor will prescribe in a month, we need to multiply the number of patients seen per day (6) by the number of work days in a month (24).
6 patients/day * 24 work days/month = 144 eye glasses
Therefore, the correct answer is 144.
Ms. Cordon is trying to go back to school to finish her degree. She has 4 classes left to take. Each of her classes will cost $480 to register. How much money will Ms. Cordon need to register for all of her classes?(1 point)
Responses
To calculate how much money Ms. Cordon will need to register for all of her classes, we need to multiply the cost of registering for each class ($480) by the number of classes she has left to take (4).
$480/class * 4 classes = $1920
Therefore, Ms. Cordon will need $1920 to register for all of her classes.
If Taylor, an artist, can draw 4 pictures an hour, how many pictures can she draw in 8 hours?(1 point)
To find out how many pictures Taylor can draw in 8 hours, we need to multiply the number of pictures she can draw in one hour (4) by the number of hours she will be drawing (8).
4 pictures/hour * 8 hours = 32 pictures
Therefore, Taylor can draw 32 pictures in 8 hours.
Danni races cars at her local racetrack. She drove her red car 400 meters in 5 seconds. If she drives the same car at the same rate, how fast will she be able to complete a race that is 600 meters?(1 point)
Responses
To find out how long it will take Danni to complete a 600-meter race at the same rate she drove her red car, we need to set up a proportion.
The ratio of distance to time should be constant, so we can set up the following proportion:
400 meters / 5 seconds = 600 meters / x seconds
Cross-multiplying, we get:
400 * x = 5 * 600
400x = 3000
Solving for x, the time it will take Danni to complete the 600-meter race, we divide both sides by 400:
x = 3000 / 400
x ≈ 7.5 seconds
Therefore, Danni will be able to complete a 600-meter race in approximately 7.5 seconds.
The science club at the local high school went on a field trip to a museum and a movie. They paid $170 for 40 tickets to the space museum and $180 for 45 tickets to the movies. For which activity did the science club pay more per ticket? How do you know?(1 point)
Responses
the movies because the ratio for the movies is higher than the ratio for the space museum
the movies because they paid the most money
the movies because they sold more tickets
the space museum because the ratio for the space museum is higher than the ratio for the movies
To determine which activity the science club paid more per ticket for, we need to calculate the ratio of the cost to the number of tickets for each activity.
For the space museum: $170 / 40 tickets = $4.25 per ticket
For the movies: $180 / 45 tickets = $4 per ticket
Comparing the ratios, we can see that the science club paid more per ticket for the space museum ($4.25) than for the movies ($4).
Therefore, the correct answer is: the space museum because the ratio for the space museum is higher than the ratio for the movies.
To predict how many eye glasses the doctor will prescribe in a month with 24 work days, we need to calculate the total number of patients seen in a month and then multiply it by the average number of prescriptions per patient.
Given that the doctor sees about 6 patients per day, we can calculate the total number of patients seen in a month by multiplying the average number of patients per day by the number of work days in a month. In this case, the number of work days in a month is given as 24.
So, the total number of patients seen in a month = 6 patients/day * 24 work days/month = 144 patients/month.
Since each patient typically receives a prescription for eye glasses, we can use this number to predict the total number of eye glasses prescribed in a month.
Therefore, the correct answer is 144.
