Will these be more than one relay exchange between 2 consecutive tenths of a mile

No

Step-by-step explanation:

data provided in the question

Long = 2 miles

distance =

based on the above information,

We can conclude that

there is not more than one relay as if we divide the 2 by 11 so it comes 0.18 which is greater than 0.1

i.e

0.18 > 0.1

So there is no need for more than one relay i.e to be exchanged between two consecutive mile

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

The answer is in the image 

The answer is in the image 

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Area of rectangle= L*b

here,

L=12.4 cm

b= 8.8 cm

A= L*b

= 12.4 * 8.8 = 109.12 cm^2
