A train stops at Atlanta, then at Bayville, and then at Colleyville. The

Nezavi [6.7K]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required of the question is not stated.

However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.

Represent the distance from Atlanta to Colleyville with AC

Represent the distance from Atlanta to Bayville with AB

Represent the distance from Bayville to Colleyville with BC

So, we have that:

$AC = 25.5\ miles$

$AB = 10\frac{2}{3}\ miles$

The relationship between AB, AC and BC is:

$AC = AB + BC$

Make BC the subject of formula:

$BC = AC - AB$

$BC = 25.5 - 10\frac{2}{3}$

Convert fraction to decimal

$BC = 25.5 - 10.7$

$BC = 14.8$

Hence, the distance from Bayville to Colleyville is 14.8 miles

Jada was training for a race. She ran 1⅓ miles on Monday. On Tuesday, she only ran of ⅚ a mile. She decided to take the day off

Lorico [155]

Answer: 5 5/12 miles

Step-by-step explanation:

The following are the distance covered by Jada for the week.

Monday = 1 1/3 miles

Tuesday = 5/6 miles

Wednesday = 0

Thursday = 2 3/4 miles

Friday = 1 1/2 miles

Total distance for the week will be:

= 1 1/3 + 5/6 + 2 3/4 + 1 1/2

The lowest common multiple of 3,6,4 and 2 is 12. The fractions will then be

1 4/12 + 10/12 + 2 9/12 + 6/12

= 3 29/12

= 3 + 2 5/12

= 5 5/12

Jada ran 5 5/12 miles this week

Dave has 10 poker chips, 5 of which are red and the other 5 of which are white. Dave likes to stack his chips and flip them over

sergey [27]

Answer:

$\frac{10!}{5!*5!}$ - $\frac{5!}{3!*2!}$

Step-by-step explanation:

Given:

10 poker chips:

5 red
5 white

Let the stack has positions (1,2,3,4,5,6,7,8,9,10)

So we can find all possible outcomes of the stack is: $\frac{10!}{5!*5!}$ =

and the possibility of a stack to be identical while flipping is: $\frac{5!}{3!*2!}$

So the different 10-chip stacks can Dave make if two stacks are not considered distinct:

$\frac{10!}{5!*5!}$ - $\frac{5!}{3!*2!}$

Fofino [41]

Answer:

Width = 139.445 ft and Length = 1721.11 ft or

Width = 860.555 ft and Length = 278.89 ft

Step-by-step explanation:

If the school has a rectangular shape, we have that its perimeter and area are:

Perimeter = 2*Length + 2*Width

Area = Length * Width

If we just want to cover 3 sides of the school, we can affirm that:

2000 = Length + 2*Width (eq1)

And the area is 240,000 ft2, so:

240000 = Length * Width (eq2)

From (eq1), we have that:

Length = 2000 - 2*Width

Using this value in (eq2), we have:

240000 = (2000 - 2*Width) * Width

240000 = 2000*Width - 2*Width^2

Width^2 - 1000*Width + 120000 = 0

Using Bhaskara's formula, we have:

Delta = 1000^2 - 120000*4 = 520000

sqrt(Delta) = 721.11

Width1 = (1000 + 721.11)/2 = 860.555 ft

Width2 = (1000 - 721.11)/2 = 139.445 ft

If we use Width = 139.445 ft, we will find Length = 1721.11 ft

If we use Width = 860.555 ft, we will find Length = 278.89 ft

Both pairs of dimensions are valid answers, as they would use 2000 feet of gate and the area of the school would be 240,000 ft2
