Answer:
<u>4-0</u>
3-0
=4/3
<u>y-0</u> =4/3
x-0
3y-0=4x-0
3y=4x
y=4/3x
Step-by-step explanation:
<u>Direct Variation:</u> 
when y = 7: 
14 = 15x
<u>Inverse variation:</u> y*x = k
15 * 2 = k
30 = k
when y = 7: 7 * x = 30
Answer:
4 weeks
Step-by-step explanation:
2 1/4 = 9/4 = 2.25
if it grows 2.25 inches in one week then in two weeks it would have grown 4.5 inches
keep adding the 2.25 inches to 14 until u get 23
:) hope this was heplful
Answer:
72 yd / min
Step-by-step explanation:
The first thing is to fully calculate the distance traveled, each lap is 200 yards and how 6 laps would be:
200 * 6 = 1200
Now, let's divide the race into how the statement tells us:
1200 * 2/3 = 800
1200 * 1/3 = 400
That is, in the first 800 yards it goes to 80 yd / min and then in the remaining 400 yards it goes to 60 yd / min, let's calculate the time Rhea lasted:
800/80 = 10 min
400/60 = 6,667 min
Which means that in total it would be:
10 + 6,667 = 16,667
In other words, Rhea took 16,667 minutes to travel 1,200 yards, so the speed would be:
1200 / 16,667 = 72
Therefore the average Rhea speed was 72 yd / min
It would be a 50/50 chance, because there is only two different things it could land on, and for each there is a 50% chance for it to land on that side so.
