Rose was tracking the movements of a rabbit and plots the movements of the rabbit on this graph.
Calculate the fastest speed that Rose observes the rabbit move.
Answer:
2.25 m/sStep-by-step explanation:
Looking at the graph, we observe that the interval CD is when the speed was the fastest
Let's calculate this, use points C(4,3), D(12,12)
(12 - 3)/(12 - 8) = 9/4 = 2.25 m/sIf it is true that z2 - 6 = 19, then z2 + 6 = ?

Step-by-step explanation:
Since its a parallelogram, opposite sides are congruent. Therefore:
BC = AD
a - 1.5 = 20.5
+1.5 +1.5
a = 22
Answer:
a=22
Step-by-step explanation:
a-1. 5 =20. 5 ( opposite side of parallelogram are equal )
or, a=20. 5+1. 5
or, a=22
you can do it from another side too.
2a-20. 8 = a + 1. 2 ( opposite side of parallelogram are equal )
or, 2a - a = 1. 2 + 20. 8
or, a = 22
Hope it will help you ☺✌

Patrick drives from P to Q at an average speed of 40 mph . His drive back from Q to P is at an average speed of 45 mph and takes two minutes less.
How far, in miles, is it from P to Q?
Answer:
Distance=12 miles
Step-by-step explanation:
d=distance
t=time going
d/t=40 mph going
t-2/60=time returning (2 minutes/60 minutes per hour)
d/(t-2/60)=45 mph returning
set up equations:
d=40t
d=45(t-2/60)
substitute:
40t=45(t-2/60)
40t=45t-90/60
40t=45t-3/2
0=5t-3/2
5t=3/2
t=0.3 hours or 18 minutes
(time returning=16 minutes)
substitute:
d=40t=40(0.3)
d=12 miles
P and Q are 12 miles far from each other.
Given that
Patrick drives from P to Q at an average speed of 40 mph
Also he drives from Q to P at an average speed of 45 mph
Let "s" be the distance between P and Q in miles.
Let "t" be the time in minutes
There are 60 minutes in 1 hours
[tex]\rm So \;in \; "t" \; minutes \; there\; will\; be = \dfrac{t}{60} \ hours[/tex]
By the definition pf average speed we can write that
[tex]\rm Average \; Speed = \dfrac{Total \; distance }{Total \; time}\\[/tex]
The speed is given in two situations in miles per hour
Case 1 When average speed = 40 mph
[tex]\rm 40 = \dfrac{s}{t/60} \\\\\rm {40 = \dfrac{60s}{t} .....(1) }[/tex]
Case 2 When average speed = 45 mph
Given that Patrick takes two minutes less
[tex]\rm 45 = \dfrac{s}{(t-2)/60} \\\\45 = \dfrac{60s}{t-2 } ....(2)[/tex]
Solving for "s" from equations (1) and (2) gives us
[tex]\rm \bold {s = 12}}[/tex]
So we can conclude that P and Q are 12 miles far from each other.

what is this 2x-5+22=?
Answer: 2x+17
Step-by-step explanation: add -5 and 22
______________________________
1.) Add −5 and 22:[tex]-5+22=17[/tex]
- You could also solve this by flipping the numbers around and subtracting 22 - 5, Which still gives you 17.
So your answer is [tex]\bold{(2x+17)}[/tex].

8 oranges cost $.78. How much will he spend to buy 40 oranges
Answer:
$3.90
Step-by-step explanation:
To get from 8 to 40, you multiply by 40/8, so you have to do the same to $.78. .78 * 40/8 is equal to 3.9, which would be $3.90.
The probability of an event is 0.001.
Which of the following best describes the event?
A The event will never occur.
B There is a small chance that the event will occur.
C The event is likely to occur.
D The event will definitely occur.
B
Step-by-step explanation:
it would be a if the chance was 0.000 but it's 0.001 so there is a very very small chance of it happening
Answer:
Step-by-step explanation:
0.001 means 1/1000
The answer depends on what is being described.
If you are putting money into a lottery if you got odds of 1 in a 1000, you'd jump for joy at such good odds.
If you are putting money into the stock market and the chances of getting any kind of return is 1/1000, I think you'd start looking for something else to do.
That said, I think the answer you want is B, but I'm not fond of the question.
