Hey mate. My best guess here is probably going to be C. 2480 cm2

Here is how I got the answer.

8•5=40.

40•62= 2480.

Hope this helps.

Runner A crosses the starting line of a marathon and runs at an average pace of 5.6 miles per hour. Half an hour later, Runner B
marishachu [46]
Time it took runner A to complete the marathon = 26.2 / 5.6 = 4 hrs 41 mins
Time it took runner B to complete the marathon = 26.2 / 6.4 = 4 hrs 6 mins

Time it took runner B to complete the marathon relative to when runner A started = 30 mins + 4 hrs 6 mins = 4 hrs 36 mins

Therefore, runner B will finnish ahead of runner A.

Let x be the time the two runners are at the same point, then
5.6x + 5.6(0.5) = 6.4x
6.4x - 5.6x = 2.8
0.8x = 2.8
x = 2.8/0.8 = 3.5
Therefore, runner B will catch up with runner A 3.5 hours after runner A starts the race.

2 plez!!!?!?!?!?!?!?!?!??!!??!?!?!!??!?!?! I can’t figure it out I’ve tried everything it’s due tomorrow AHAHAHAH
harkovskaia [24]
So to do this one, you have to do the problem backwards!

The equation looks like this with everything plugged in:

272.2 = 2(3.14)r

You are looking for r, so start dividing

272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r

Therefore the radius is about 43.3 in.

I hope I helped!

Question 12
zvonat [6]
Weird question xD

You have to use the Pythagorean theorem on this one.
a^2 + b^2 = c^2
11^2 + h^2 = 12^2
121 + h^2 = 144
h^2 = 23
h = 4.79583

Is the relationship shown by the data linear? If so, model the data with an equation.
Marina CMI [18]

Answer:

4th option

Step-by-step explanation:

The relationship is linear,

putting the value of x in the right side of the equation of option 4, you'll get the value of the left side

putting, x=1

y+4=-1/2(x-1)

y=-1/2(1-1)-4

y=-4

putting, x=7

y+4=-1/2(7-1)

y=-1/2(6)-4

y=-6/2-4

y=-3-4

y=-7
