Answer:

Shortest distance = 23/24

Farthest distance = 3 17/24 miles

Step-by-step explanation:

Distance of home from school = 2 1/3 miles

Distance of shop from school = 1 3/8 miles

Shortest distance possible :

(2 1/3 - 1 3/8) miles

(7/3 - 11/8) miles

L. C. M = 24

(56 - 33) / 24

23 / 24 miles

The farthest distance :

(2 1/3 + 1 3/8) miles

(7/3 + 11/8) miles

L. C. M = 24

(56 + 33) / 24

89 / 24

= 3 17/24 miles

Answer:

Final Value = 17.50 × (1 + 4/100)

Final Value = 18.2

Answer:

x=20

Step-by-step explanation:

use proportions

121:11

or 11:1

take 10 and multiply it by 11 to get the length of the other side.

110

set the equation equal to that length

5x+10=110

-10 on both sides

5x=100

÷5 on both sides

x=20

Answer:

131.3 miles

Step-by-step explanation:

The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.

Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:

d₁ + d₂ = 374 miles       (1)

Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence

For car c:

2x = d₁/t

t = d₁ / 2x

For car d;

x = d₂/t

t = d₂/ x

Since it takes both cars the same time to meet at the same point, therefore:

d₁/2x = d₂ / x

d₁ = 2d₂

d₁ - 2d₂ = 0         (2)

Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles

Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles

   Both the cars will meet at 131.33 miles from Boston.

Given in the question,

Distance between two cars = 118 + 256 = 374 miles

Let these cars meet at a point P.

Let the distance between the car C and point P = 'x' miles

Therefore, distance between car D and point P = (374 - x) miles

Time taken 't' by car C to travel the distance 'x' miles,

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

[tex]t=\frac{x}{2v}[/tex]  -------(1)

Time taken 't' by the car D to travel (374 - x) miles,

[tex]t=\frac{(374-x)}{v}[/tex] ---------(2)

Substitute the value of 't' from equation (2) to equation (1),

[tex]\frac{x}{2v}=\frac{374-x}{v}[/tex]

[tex]\frac{x}{2}=374-x[/tex]

[tex]\frac{3x}{2}=374[/tex]

[tex]x=249.33\text{ miles}[/tex]

From the picture attached,

Distance between Boston and the meeting point = (x - 118) miles

                                                                                   = 249.33 - 118

                                                                                   = 131.33 miles

     Therefore, both the cars will meet at a point 131.33 miles distant from Boston.

Answer:

  [tex]\text{c. }f(n)=3f(n-1);f(1)=2[/tex]

Step-by-step explanation:

The first term is 2, so part of the recursive definition is ...

  f(1) = 2

The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...

  f(n) = 3·f(n -1)

These two parts of the definition match choice C.
