To determine the total distance traveled by an object in constant speed, just multiply the speed by the time. So, for the car, the total distance traveled is,
distance by car = (20 m/s)(5s) = 100 m
For decelerating object, the distance traveled is,
distance = Vt - (at^2)/2
For the truck,
distance by truck = (20 m/s)(10s) - (2m/s^2)((10s)^2)/2 = 100 m
Relatively, both have traveled the same distance.
In order to solve this, you need to put it into a fraction form.
First for every 225 employees there's 27 supervisors.
25 x
___ = ___
225 252
I got the 252 by adding 225+27(who are the new employees)
So then you need to cross multiply. And get them to equal the same number.
So 25×252= 6,300
Then Divide 6,300 by the old denominator 225.
6,300÷225= 28 new employees
Therefore there will be a total of 28 employees.

Answer: 7.5 items
Step-by-step explanation:
Both Karen and James had 30 stocking items.
Karen bought 35% of her items;
= 35% * 30
= 10.5 items
James has bought 60%;
= 60% * 30
= 18 items
= 18 - 10.5
= 7.5 items
The best way to do this is to set up a proportion
420 x
------ = ------
600 100
then cross multiply and divide
420 times 100 = 42000/600=70
the correct answer is C. 70 people
I hope I've helped!
Answer: H
Step-by-step explanation:
We can see this rectangular prism will have side lengths of 5, 3, 7.
So we can use the fact Surface Area = 2(lh+wh+lw) to get:
2(15 + 35 + 21) = 2(71) = 142
