Length of circular track is:

L = 2*r*pi

He run 3/4 of it so length is:
L' = 3*2/4*r*pi = 3/2*r*pi

To calculate speed of his movement we use formula:
v = s/t where s = L' and t = 1 minute 45 seconds = 105 seconds

v = L'/t = 3*r*pi/2*105

v = r* pi/70

If we take that r = 1
 
answer
\pi /70

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.
jarptica [38.1K]
Formula for perimeter of rectangle:
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft 

Answer: 252 ft

Ab= 6cm Ac=12cm <br> Calculate the length of Ad <br> Give your answer to 3 significant figures
Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that a^2+b^2=c^2

Therefore, 12^2-6^2=CB^2

CB=\sqrt{108} (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

Sin55=CB/CD\\Therefore, CD= 12.686

Find the slope pf the line on the grap (-2,2),(4,0) reduce all fractional answers to the lowest term.
wariber [46]
Hey there! :) 

We're trying to find the slope of the line on the graph (not given, but that's okay). We're given the points (-2, 2) and (4, 0). 

Using the slope equation, we simply just have to plug our points in and boom - there's your slope! 

Slope equation : m = y₂ - y₁ / x₂ - x₁

Now, using our given points, we can very simply plug everything in! :)

Now, in case you didn't know which number aligns with which variable, I'll go ahead and help you out with this. 

x₁ = -2 , x₂ = 4 , y₁ = 2 , y₂ = 0

Now, let's plug and chug!

m = (0 - 2) / (4 - (-2))

Simplify.

m = -2 / 4 + 2

Simplify.

m = -2 / 6

Simplify.

m = -1/3

So, our slope is -1/3.

~Hope I helped!~
