he total time is 4 seconds. The elevator descends 10 feet each second so the total is:
4seconds x -10 feet/sec = -40 feet
The total change in elevation is -40 feet. You need the negative sign because the elevator is moving downward. Hope this helps!

Answer:
14 Students made the team.
Step-by-step explanation:
There are different ways to solve percentages, but I only use one.
[tex]\frac{20}{100}[/tex] • [tex]\frac{x}{70}[/tex] So you cross multiply 20 and 70 which is 1400. Then you divide 1400 by 100 which is 14.

Answer:
Divide both sides by a constant to simplify the equation. Thus the second option.
Step-by-step explanation:
Solve for x:
9 - 10 x = -1
Hint: | Isolate terms with x to the left hand side.
Subtract 9 from both sides:
(9 - 9) - 10 x = -9 - 1
Hint: | Look for the difference of two identical terms.
9 - 9 = 0:
-10 x = -9 - 1
Hint: | Evaluate -9 - 1.
-9 - 1 = -10:
-10 x = -10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -10 x = -10 by -10:
(-10 x)/(-10) = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
x = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:

Write the standard form of the equation of the circle with radius 7 and center (4,−9).
Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2

Answer:
The mapping represents y as a function of x, because each x value corresponds to exactly 1 y value.
Step-by-step explanation:
Functions are defined to map out to only one value so that rules everything else out and leave us with only one answer.

Answer:
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4Round 3,689,423 to the nearest hundred thousand.

How do you solve 5x + 7 = 2x + 1
Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2
3.) rewrite r(x) in expanded form

Answer:
[tex]{\huge{\pink{\underline{\underline{QuEsTiOn}}}}}[/tex]
rewrite r(x) in expanded form

[tex](x-3)(x+5)\\
=>x(x + 5) - 3(x + 5) \\

Find the sum.
(n+8)+(n−12)
=
n=2
Reorder terms:
(8+n)+(n-12)=0
Remover first parentheses :
8+n+(n-12)=0
Reorder (again):
8-12+n+n=0
Simplify:
-4+2n=0
Add 4 to both sides:
2n=4
Divide and you’re done!
n=2

Annabelle lives at Bermondsey in London. She has to speak at a conference inBirmingham at 10.30am.
It will take her an hour from her home to get to Euston Rail
Station, from where she will get a train to Birmingham.
The train journey from Euston
to Bimingham is an hour and 10 minutes.
Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.
The meeting venue in Birmingham is a 5-minute walk from the station.
What is the latest time that Annabelle can leave home, if she is to make it on time for
the meeting in Birmingham
Show your work.
Please HELP!!! DUE TODAY!!
Thank you so much.
Answer:
7:45
Step-by-step explanation:
work backwards from 10:30!
u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.
then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)
the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.
since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.
hope i was helpful !
The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting
Time of meeting = 10.30am
Time she will spend before getting to meeting:
home to get to Euston Rail Station = 1 hourtrain journey from Euston to Bimingham = 1 hour 10 minutesTrains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.The latest time is 45 minutes
Walk from the meeting venue in Birmingham from the station = 5 minute walkTotal time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes
= 3 hours
Counting 3 hours backward from 10:30 am = 7:30 am
Therefore, the latest time Annabelle can leave home is 7:30 am
