<h3>Answer: A) Toyota Prius</h3>

========================================================

Explanation:

To get the mileage per gallon, you divide the number of miles over the number of gallons.

For the Chevy Volt, the mileage is 571.95/12.3 = 46.5 miles per gallon (mpg)

For the Prius, the mpg rating is 753.48/15.6 = 48.3

So the Toyota gets the better mileage per gallon.

---------

If you're curious why we divide the numbers like that, consider this example

You drive 200 miles using 5 gallons of gas. We can form the ratio

200 miles : 5 gallons

To get the mpg rating, we need to know how many miles we can drive on 1 gallon of gas. So we divide both sides by 5

200/5 miles : 5/5 gallons

40 miles : 1 gallon

This hypothetical situation leads to 40 mpg

Indicate the equation of the line through (2, -4) and having slope of 3/5.
Nastasia [14]
Y = mx + b.....the m is for the slope , (2,-4)...x = 2 and y = -4
now we sub
-4 = 3/5(2) + b
-4 = 6/5 + b
-4 - 6/5 = b
-20/5 - 6/5 = b
- 26/5 = b

so ur equation is : y = 3/5x - 26/5 <== slope intercept form
or if u need it in standard form :
y = 3/5x - 26/5....(5)
5y = 3x - 26
-3x + 5y = -26...(-1)
3x - 5y = 26 <==standard form

Continuation of the other six questions find the value of eggs and tangent 
n200080 [17]

Answer:

Step-by-step explanation:

1) ?

I can't see what that one given angle is ..  but it's that  mystery angle subtracted from 180 give the angle   BOA   then you know that's an isosceles triangle again that the BOA is part of... so then just subtract BOA from 180 to find the two other angle of that triangle... they are the small so just divide your answer of  180-BOA /2 is the angle of each.. then since you know those to smaller angles subtract one from 90  to find the angle BAX

2) ( as we would read normally)

You're making this really tough on me.. I can just barely read the equations

I think it's  1+6x  and 7x-3  .  b/c they are the same length sides you can set those equal

1+6x = 7x -3

4+6x = 7x

4 = x

that worked out well :

for the tangent..   it's   Tan(Ф)= Opp/ Adj

but I don't know which side they want to solve for.. I think you may have left off some of the instructions????  :/

ohh I think they really mean.. what's the length of the tangent lines .. that was confusing to me.. :/ just plug in 4 into x for either eq.

1+6(4) = 25

or

7(4)-3=25

tangent is 25

3)

x-2 = 2x-10

x+8 = 2x

8 = x

again they made it work out easy :)

Then plug 8 into either equation to find the length of the tangent lines

8-2=10

tangent is 10

4) = 2)   ??? they are the same question  maybe  you meant to put something else?
