How is 21\30 bigger then 2\3

strojnjashka [21]

By reducing 21/30 you dived 21 and 30 by 3 and you will get 7/10. Is 7/10 larger than 2/3? If we put these fractions in decimal form we will see 7/10 turns into 0.7 and 2/3 turns into 0.667. So the answer is 21/30 is larger than 2/3.

Victor was having a hard time deciding which new vehicle he should buy. He decided to make the final decision based on the gas e

Amanda [17]

Answer:

Victor should buy Legend because it has a better unit rate

Step-by-step explanation:

See attachment for complete question.

To determine which car has more gas efficiency, we have to calculate the slope of each car.

Vehicle 1: Legend

Take any two corresponding points from the table

$(x_1,y_1) = (4,72)$

$(x_2,y_2) = (12,216)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{216 - 72}{12 - 4}$

$m = \frac{144}{8}$

$m = 18$

This implies that this vehicle (legend) travels 18 miles per gallon of gas

Vehicle 2: Supreme

Take any two corresponding points from the graph

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (15,250)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{250 - 0}{15 - 0}$

$m = \frac{250}{15}$

$m = 16.7$

This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas

Base on the calculations above, Victor should buy Legend because it has a better unit rate

Eleven is 20% of ____

ollegr [7]

Convert to a decimal which would be 0.55 (11/20).

Then you want to multiply 0.55 by 100 (which is a whole number, all % is going to come from 100) to convert to a full % -> 0.55*100

Then you will simplify 0.55*100

You answer will be 55%.
