Their speed of separation will be equal to the sum of their speeds because they are in opposite directions.
Speed of separation = 40 + 50 = 90 miles per hour
Time = distance / speed
Time = 405 / 90
Time = 4.5 hours

Answer:
The surface area is 91
Step-by-step explanation:
3*4=12
12/2=6
6*2=12
7*5=30
4*7=28
3*7=21
12+30+28+21=91
The equations that are on the left are caculations triangle calcuations. The equations on the right are the ones that equal each of the 2d shapes in the prism and if u add them all up you get your surface area.
Answer:
1:5
Step-by-step explanation:
There are four, any number then zero.
1.) First you have to write down your square numbers. Remember to only write the first couple of numbers because as square numbers get bigger the difference between them does.5 is a small number so only write the first couple numbers.
1,4,9,16,25
2.) Then you find the difference between each number.
25 - 16= 9
9 - 4 =5
4 - 1 =3
3.) look at which numbers have the difference of 5 and in this case it will be 9 and 4.
hope this helped.
