if your car gets 26 miles per gallon how much does it cost to drive 420 miles when gas is $2.80 per gallon​
Kitty [74]

Answer:

$45.22

Step-by-step explanation:

The number of miles per gallon can be represented by the ratio:

\frac{miles}{gallon}=\frac{26}{1}

Since we know the unit rate of 26 miles per gallon of gas, we can set up a proportion, or equivalent ratios, to find the number of gallons needed for 420 miles:

\frac{26}{1}=\frac{420}{x}, where 'x' is the number of gallons of gas

cross-multiply and divide:  26x = 420 or x ≈ 16.15 gallons

If gas is $2.80 per gallon, take the total number of gallons needed and multiply by $2.80:

16.15 x $2.80 = $45.22

Which image shows a plane slicing a double-napped cone to produce a hyperbola?<br><br> Answer is D
Butoxors [25]

The <u>second image</u> in the diagram is a hyperbola. As can be seen, the plane cutting the cone can be at any angle but never equal to the slant angle of the cone. This has a very important implication. The plane cuts both cones of the double-napped cone. The third double-napped cone of Figure 3 shows two hyperbolas.
