19.2 is the answer. you add them up then estimate to find you answer.
Speed of Tim = 60 miles/hour
Speed of Joe = 45 miles/ hour
Distance = Speed x Time
A 3 hours, Tim had travelled 60 x 3 miles = 180 miles.
At 3 hours, Joe had travelled 45 x 3 miles = 135.
The difference between the distances is 45.
Therefore, they were 45 miles apart after 3 hours.
I hope this is right.
You can choose from 20 students for the first student, 19 for the second, 18 for the third, ..., 14 for the seventh student.
That gives you 20 * 19 * 18 * 17 * 16 * 15 * 14.
That number would allow you to write the students in different order. Since order here does not matter, any group with the same students in any order is the same group, you need to divide by the number of way you can order 7 items. Divide by 7 * 6 * 5 * 4 * 3 * 2 * 1
(20 * 19 * 18 * 17 * 16 * 15 * 14)/(7 * 6 * 5 * 4 * 3 * 2 * 1) = 77,520
Answer: 77,520
Answer:
can i pls have brainlysit? I really need them. In return I will try to answer this question
Step-by-step explanation:
length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)
use this formula as a first step.
then substitute your values in
length = 3 cm
width = 4 cm
height = 5 cm
so 3 * 4 * 5 = 60 cm^3
The answer is B! hope that helped
