Answer:
Silver car
Step-by-step explanation:
It seems pretty hard but it's actually REALLY easy. gas mileage means the number of miles you can go on a particular amount of gallons. But the gallons have to be the same for both cars so that it's fair.
so let's go with 10 gallons. pretty broad number right?
so to get 12 gallons(the gallons for the blue car) to 10, We divide it by 12 then multiply it by 10. Try it yourself, (12/12)*10=???
then we do that to 384 (the miles for the blue car)
(384/12)*10=320
so 320 is the mileage for the first car. Repeat the steps for the silver car!
(14/14)*10=10
so then: (504/14)*10= 360.
So which is bigger, 320 or 360?
360 is bigger, meaning it has better gas mileage.
Answer:
Yes the triangles are similar.
if you look at Angle C it's 60° and F is also 60°
60 + 67 is 127
127 + 53 is 180° which is the amount a triangle is. (assuming that E is 67°)
Answer:
$311.49
Step-by-step explanation:
*remember when turning percents to decimals you move the decimal to spots to the left. so 5% as a decimal is 0.05 and 10% as a decimal is 10
step 1) multiply 349.99 by 0.18 to find the price of discount. 349.99 times 0.18 is 62.9
step 2) subtract 62.9 from 349.99 to find the price with the discount. the answer is 287.09
step 3) multiply 287.09 times 0.085 to find the price of the tax. which is 24.4
step 4) add 287.09 and 24.4 which is 311.49
Answer:
Dave is 27. His brother is 18.
Step-by-step explanation:
Dave is 9 years older than his brother, so if his brother is 18, he is 27. If you doubled the brother's age (18) you would get 36. Then you subtract 36 by 9 and get 27. <3
