She can spend 6minutes with each friend.
Explanation step by step:
Maria has 30 min break, she walks 3 min to another floor- we have deduct that 3 min from 30 mi
30-3=27
Than she walks 3 min back to her floor
27-3=24
She has 24 minutes left which she equally divided between 4 friends
24:4=6
6 is the answer
The answer is roughly 103 square feet.
You can get this by first transforming the measurements using the scale factor. To do this, we need to multiply each measurement by 30.
5.5 in * 30 = 165 in
3 in * 30 = 90 in
Now we have the measurements of the room, we can multiply to find the area.
90 in * 165 in = 14850 square inches.
Now to turn this into feet we need to divide by the number of square inches in a square foot (144).
14850 square inches/ 144 = 103 square feet
Three equivalent ratios are: 8/6, 12/9, 16/12
Answer:
10 more students chose purple than red as their favorite color
Step-by-step explanation:
Step 1
Determine the proportion of students that chose each color
purple=26%
red=22%
Step 2
Use the expression for the number of students per color as follows;
Number of students per color=proportion per color×total number of students
for purple;
proportion that chose purple=26%
total number of students=250
replacing;
Number of students that chose purple=(26/100)×250=65 students
for red;
proportion that chose red=22%
total number of students=250
replacing;
Number of students that chose purple=(22/100)×250=55 students
Step 3
Difference=65-55=10
10 more students chose purple than red as their favorite color
