Answer:
800. Here's why:
Step-by-step explanation:
This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
So when you solve, it’s going to be y=60x-30. So on the graph, you start at -30 and add 60 up and one box over.
D=m-7
d+m=25
m-7+m=25
2m-7=25
2m=32
m=16
d=16-7
d=9
don is 9
You have to use Pythagoras' theorem for this!
The triangle formed is 6 units across, and 8 units down, which means we can form an equation like this:
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10.
The answer is 10 :)
Answer:
a. 17.03 mi/hr b. 0 mi/hr or 18.99 mi/hr c. 17.03 mi/hr
Step-by-step explanation:
Av Vel =(V1+V2)/2 =26
Av Speed =d/t=55=> d=55t1
D=d+d 2d =2(55t1)=110t1
av Vel =110ti/(t1+t2)
t2=3.23t1 => total time =4.23 t1
a. V2=55t1/3.23t1 =17.03 mi/hr
b. velocity as vector quantity (v2-v1)/2 =18.88 or displacement d-d=0 and av velocity = (d-d)/2= 0/2
c. since all information are standing but opposite direction which doesn't affect speed as scalar av speed is the same
