Which number is divisible by 3 and 5 a. 130 b. 325 c. 4113 d. 2040

1 answer:

8 0

A number that is divisible by 5 is one that ends with either a 5 or 0. To find a number that is divisible by 3 add up the digits and if they are divisible by 3, the number also is. That rules c out because it doesn't end with a 5 or 0. 130 and 325 won't work because they are not divisible by 3. The answer would be 2040.

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.

Answer:

x=-2

Step-by-step explanation:

the while goal of this is to isolate the x on one sideso x= the answer, so

first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you x=-2.
