3. Jack walked
of a mile in
of
1/4 of
an hour. How far will Jack walk in one hour?

distance = rate * time

rate = distance / time

     = 2/3 mile divided by 1/2 hour

     = 2/3 * 2/1 = 4/3 mph = 1 and 1/3 mph

His speed is 4/3 mph = 1 and 1/3 mph = 1.3 mph

So

 1 mile = (4/3 mph) * TIME

Solving for Time T, it will take him t = 3/4 <--- the RECIPROCAL

            and 3/4 hour = 45 minutes

Jack walks 1 mile in 45 minutes = 3/4 hour

Step-by-step explanation:

PLS MAKE ME AS BRAINLIST

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
