Answer:

$1,616.91

Step-by-step explanation:

Data provided in the question:

Total distance to be driven = 22,000 miles

Average of hybrid = 38 mpg

Thus,

total fuel required by hybrid to travel 22,000 miles = $\frac{22,000}{38}$

= 578.95 gallons

and,

Average of SUV = 21 mpg

total fuel required by SUV to travel 22,000 miles = $\frac{22,000}{21}$

= 1047.62 gallons

Therefore,

savings in fuel = 1047.62 gallons - 578.95 gallons = 468.67 gallons

Thus,

the savings in fuel expenses = Savings in fuel × Cost of gas

= 468.67 × 3.45

= $1,616.91

Tom supports North Storm Football Club. At the match between North Storm and West Stanford there were 71,167 spectators. If 41,1

dangina [55]

Answer:
30,058 spectator

Explanation:
The total number of spectators is equal to the sum of West Stanford's and North Storm's supporters.
We are given that:
Total number of spectators = 71,167 spectator
North Storm spectators = 41,109 spectator
So, to get the number of West Stanford spectators, all we have to do is subtract North Storm spectators from the total spectators as follows:
West Stanford spectators = 71,167 - 41,109 = 30,058 spectator

Hope this helps :)

The cost for traveling in tina's taxi is 9 pence per 100m

lora16 [44]

Answer:

1405.8 pence fare

Step-by-step explanation:

First we have to change meters into km by dividing the distance by 1000

here we have:

Fare: 9 pence

Distance: 100m/1000 = 0.1 km

when it was

0.1 km -----------> 9 pence fare

if 1 km ------------> 9/0.1 fare

if 15.62 ------------> 9*15.62/0.1

15.62 km ----------> 1405.8 pence fare.

A linear function that represents the number of hot dogs purchased at a football game is compared to a different linear function

Vsevolod [243]

Answer:

Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other

Step-by-step explanation:

Take for instance 2 linear functions, and

If they intersect in some point in the space, say that is

Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)

So, we can compare the two functions and get the following result;

It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.

hope this helps!

Use two points to enter an equation for the function. Give your answer in the form a(b)^n. In the event that a = 1, give your an

levacccp [35]

Answer:

$m(n) = 24 (0.75)^n$

Step-by-step explanation:

1) The two points are:

a) On the first swing she swings forward by 18 degrees: (1, 18)

b) On the second swing she only comes 13.5 degrees forward: (2,13.5)

2) The general equation using the form given is:

$m(n)=A(B)^n$

3) Substitute the two points:

$18=A(B)\\ \\ 13.5=A(B)^2$

4) Divide the second equation by the first one:

⇒ 13.5 / 18 = B

⇒ B = 0.75

5) Substitue B = 0.75 into the first equation:

18 = A (0.75) ⇒ A = 18 / 0.75 = 24

Hence, the equation is:

$m(n) = 24 (0.75)^n$
