The answer to the question is 1 and 3/4
Answer:
5
Step-by-step explanation:
We start by seeing how many families we have in total, which is 20. We then must subtract the number of families with girls only, the number of families with both boys and girls, and the number of families with no children. 20 - 7 is 13, then 13 - 8 is 5, and 5 - 0 is 5.
A because the 6 and 3 cancel out
Then 2 x 8 is (16) and 15 x 5 is (75)
Making it A
Answer:
1. rational number
2. a positive rational number
Step-by-step explanation:
A rational number is a number that can be expressed as a simple fraction. When two rational numbers are multiplied together, the only logical answer would be for the outcome/product to also be rational.
The reciprocal of a positive rational number is also a positive rational number because if the original number was negative, the reciprocal would also be negative since the signs wouldn't change (in this case, the original number is positive). Since the original number is already a rational number, just by flipping it (the reciprocal), it would not change to an irrational, but instead stay the same.
Answer:
Step-by-step explanation:
The distance that you travelled in your hummer between Olympia and Spokane is 319.4 miles.
You fill up your gas tank with 28.68 gallons of premium gasoline that costs $2.89 per gallon. This means that the total cost of premium gasoline that you bought would be
2.89 × 28.68 = $82.8852
your gas mileage in miles per gallon is 319.4/28.68 = 11.14 miles per gallon.
Therefore, if it costs $82.8852 to drive 319.4 miles,
then the cost of just one mile in your hummer would be
82.8852/319.4 = $0.26 per mile.
