Zielflug [23.3K]3 years ago
6 0

Answer:

D: 6

Step-by-step explanation:

Let x mph be the rate of the faster jogger

Therefore (x-2) mph is the rate of the slower jogger

After 3 hours faster jogger will be 3x miles from the starting point

Whereas after the 3 hours slower jogger will be 3(x-2) miles from the starting point but in the opposite direction.

Since they are 30 miles apart 3x+3(x-2)=30

3x+3x-6=30

⇒ 3x+3x=30 +6

⇒ 6x=36

⇒ x=6

Therefore the rate of the faster jogger = 6 mph

Mei has 8 jars of soup. Each jar contains 300 milliliters of soup. What is the smallest pot Mei can use to heat all the soup.[PL
Kobotan [32]

Answer: A pot of 2400ml

Step-by-step explanation: Ok, mei has 8 jars, and each jar has 300ml of soup, so the total amount of soup is 8 times 300ml

N = 8*300ml = 2400ml

So the smallest pot that mei can use to heat the soup is a pot that has exactly that volume. 2400ml, (discarding the fact that the volume of the soup will change as it is heated up)

What geometric term does the surface of a chalkboard represent?
Fittoniya [83]
A) Plane because it is a flat surface that extends in two dimensions but exists in a three-dimensional space, and also it isn't a point, a line, or an angle because a line is infinitely thin, a point is infinitesimally small, and an angle is a measurement, not a surface.
