100 hours is your answer
3000/75=40mph
4000/40=100 hours

Set up a proportion:
\frac{3000}{75}=\frac{4000}{x}
To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100

It will take her 100 hours to drive 4000 miles assuming she continues to travel at this rate.

You have a standard deck of 52 playing cards and draw out a single card at random. What is the chance of picking out a nine? Wri
motikmotik

There are 9 number cards from 2 to 10 in a deck of cards.

(2-10) has one 9

(2-10) has one 9

(2-10) has one 9

(2-10) has one 9

There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.

The chance or probability of taking out a 9 is (36/52).

Reducing this fraction to the lowest terms we get 9/13.

The measures of the legs of a right triangle are 15 m and 20 m. Use the triangle measures and substitute the lengths for a and b
DochEvi [55]

Answer:

25

Step-by-step explanation:

We can use the Pythagorean theorem to determine the length of the hypotenuse

a^2 + b^2 = c^2

15^2 + 20 ^2 = c^2

225 + 400 = c^2

625 = c^2

Take the square root of each side

sqrt(625) = sqrt(c^2)

25 = c
