A go-cart racetrack has 100-meter straightaways and semicircular ends with diameters of 40 meters. Calculate the average speed i

emmainna [20.7K]

Answer:

Average speed of go cart is 217.07 meters per minute.

Step-by-step explanation:

We are given the following in the question:

Length of straightway racetrack = 100 m

Diameter of semicircular end = 40 m

Radius =

$r = \dfrac{d}{2} = \dfrac{40}{2} = 20\text{ m}$

Perimeter of racetrack =

Perimeter of semicircle + 2(Length of straightway) + Perimeter of semicircle

$=\pi r + 2(100) + \pi r\\=2\pi r + 2(200)\\=(2\times 3.14\times 20) + 200\\=325.6\text{ m}$

Speed =

$s = \dfrac{\text{Distance}}{\text{Time}}\\\\s = \dfrac{4\times \text{Perimeter of track}}{6}\\\\s = \dfrac{4\times 325.6}{6}\\\\s = 217.06\text{ meter per minute}$

Thus, average speed of go cart is 217.07 meters per minute.

Rosa finds the product of 32 and 96. she rewrites 96 as a sum or difference of two numbers and uses the distributive property. w

Nady [450]

Solution:

We are given with the two numbers=32 and 96

Product of the given numbers= $32*96= 3072$

But Rosa rewrites the 96 as a sum or difference of two numbers and uses the distributive property

As we know, the Distributive property is $a(b+c)= ab+ac$

Now, $32*96 = 32*(100-4) = 3200-128$

So, option 'd' is correct
