15.5-3.5=12. this is how many hours he has worked already.

12/1⅓=9. this is because how many hours he has worked per how many hours he worked per day to show how many days he worked

the answer is 9 days.

12hours * 1day/1⅓ hours
^^ignore that if it doesn't make sense, but basically the hours will cancel and you'd be left with days as your only unit to show why you would divide 12 by 1⅓


hope this helped!

Steve and Elizabeth decide to become partners in a children’s cooking school. They need $80,000 for the franchise. They invest i
PilotLPTM [1.2K]

Answer:

The share of Steve  is $34,285 .71

The share of Elizabeth  is  $45,714.28

Step-by-step explanation:

The total investment of Steve and Elizabeth in cooking school = $80, 000

The ratio of investment of  Steve and Elizabeth  = 3: 4

Let us assume the common factor in the ratio is m.

So, the ratio of  Steve = 3 m

and the ratio of  Steve = 4 m

So, according to the question:

⇒ 3 m + 4 m   =  80,000

or, 7 m = 80,000

⇒ m = 80,000 / 7 = 11,428.57

or, m = 11,428.57

⇒ The share of Steve = 3 m = 3 x (11,428.57)  = 34,285 .71

⇒ The share of Elizabeth = 4 m = 4 x (11,428.57)  = 45,714.28

Answer:

Speed = Distance/time in km/h

a) 18 feet in 20 minutes

0.0054864 km/0.333333hours

=0.01645921645 km/h

b) 90 feet in 2.5 hours

0.027432km/2.5

=0.0109728 km/h

c) 20 yards in 1.5 hours

0.018288km/1.5

=0.012192 km/h

d) 3 2/3 yards in 15 minutes

0.003352800000003048km/0.25hours

=0.0134112

So I think its safe to say that A is the fastest in comparison
