Answer:
the maximum number of crates that can be stacked between the floor and ceiling
where 1 foot = 12 inches. SO the answer is that a maximum of 10 crates can be stacked from floor to ceiling.
Step-by-step explanation:
i) the maximum number of crates that can be stacked between the floor and ceiling
where 1 foot = 12 inches
first we can find the slope between the two points by using the slope formula
m=(y₂-y₁)/(x₂-x₁)
m=(3-(-7))/(-3-2)
m=(3+7)/(-3-2)
m=10/-5
m= -2
now that we have the slope, we can set up our equation. slope-intercept form is:
y=mx+b
where m is the slope and b is the y-intercept.
since we have the slope, we can choose one of the points that we are given to plug in for x and y, and then solve for b
-7 = 2(-2) + b
-7 = -4 + b
-3 = b
now that we have all the values we need, we can put it into our slope-intercept formula.
y=mx+b
y=-2x+(-3)
y = -2x -3
hope this helps
Answer:
He is watching TV for 2 hours and 40 minutes.
Step-by-step explanation:
We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.
As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;
1 episode = 40 minutes
4 episodes = 4
40
= 160 minutes
So, the length of four episodes together is 160 minutes.
Now, we have to convert the time in hours and minutes;
As we know that 1 hour = 60 minutes
160 minutes = 120 minutes + 40 minutes
= 2 hours + 40 minutes
Hence, the length of four episodes together is 2 hours and 40 minutes.
Answer: A 13.4
Step-by-step
a^2 + b^2= c^2 4^2 + b^2 = 14^2 16+ b^2= 195 b^2= 180 b= square root of 180 b= 6 square root of 5 or 13.42
