Answer:

car 2

Step-by-step explanation:

Divide distance by size gas tank size.

For car 1 : 360 /12 = 30 miles per gallon.

For car 2 : 490/14 = 35 miles per gallon etc.

Car3 and car 4 are lower, making car 2 economical with best gas mileage

Answer:

17. surface area ≈ 441.84

04π m² or  1387.38  m²

18. Ratio of volumes = 8/27

19. volume of the smaller solid = 339 yards³

Step-by-step explanation:

17 .

To find the surface area of the sphere we have to find the radius of the sphere first.

volume of a sphere = 4/3πr³

volume = 1548π m³

r = ?

volume of a sphere = 4/3πr³

1548π = 4/3 × π × r³

multiply both sides by 3/4

1548π × 3/4 = πr³

4644π/4 = πr³

1161π = πr³

divide both sides by π

r³ = 1161

cube root both sides

r = ∛1161

r = 10.5101942

r ≈ 10. 51

surface area of a sphere = 4πr²

surface area = 4 × π × 10.51²

surface area = 4 × 110.4601  × π

surface area = 441.8404π m²  

surface area = 441.8404 × 3.14 = 1387.378856  m² ≈ 1387.38 m²

18

If two figure or solid are similar with scale factor or ratio of x/y then the ratio of their volume is (x/y)³. If the ratio of of two similar prism is 2 : 3 the volume will be (2/3)³ = 8/27 .

19

If two solids are similar then the ratio of their surface area is the squared of the scale factor.

121/361 = (x/y)²

square root both sides

x/y = 11/19

If two solids are similar then the ratio of their volume is the cube of the scale factor.

(11/19)³ = a/1747

1331/6859  = a/1747

cross multiply

6859a = 2325257

divide both sides by 6859

a = 2325257/6859

a = 339.008164455

a ≈ 339 yards³

volume of the smaller solid ≈ 339 yards³

The list that orders the fractions from least to greatest is:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}

<h3>Ordering of fractions</h3>
  • To order the fractions from least to greatest, we have to realize their conversion to decimal.
  • To realize the conversion, the numerator is divided by the denominator, as ordering decimal numbers are easier than fractions.

Hence, the fractions converted to decimal are:

  • \frac{2}{3} = 0.6667.
  • \frac{7}{12} = 0.5833.
  • \frac{17}{24} = 0.7083
  • \frac{3}{4} = 0.75

Hence, the list from least to greatest is, according to the results of the conversions:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}
