Answer: 2 2/5 distance

Step-by-step explanation:

You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!

ILL MARK AS BRAINLIEST!! AND GIVE 10 POINTS!!! Are the following lines parallel, perpendicular, or neither?
Licemer1 [7]

Answer:

b perpendicular

Step-by-step explanation:

all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites

Line 1)      -7 -8 / -3 -2  X= 3X

Line 2)      -3 - 0 / 12 - 3  X = -1 / 3X

Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.

If you want to buy an item in a store that cost $43 and is on sale for 40% off, then how much would the item actually cost you a
expeople1 [14]

Answer:

$25.80

Step-by-step explanation:

40% = 40/ 100 = 4/10 = 0,4

There is a 40% discount, which means that the amount multiplied by more then 1 (for example 1,4) would increase the amount... That isn't right because it is a discount!

So you need to subtract the 40%, so (1 - 0.4 =) 0.6

The amount multiplied by 0.6 will be the correct amount, being $43 * 0.6 = $25.80 (rounded to the nearest cent).

The amount the item actually cost after the discount is $25.80

Cody has 7/8 pound of cheese. he uses 1/7 since there are 16 ounces in a pound how much is left
bagirrra123 [75]
Step One
Find the fraction left.
Starting amount = 7/8 pound
Used amount = 1/7 of a pound.

The common denominator of these two fractions is 8 * 7 = 56

Amount left = amount started with - amount used
Amount left = 7/8 - 1/7
Amount left = \frac{7 *7 }{8 * 7} -  \frac{1 * 8}{7 * 8}
Amount left = \frac{49 }{56} - \frac{ 8}{56}
Amount left = 41 / 56 pounds

Step Two
Convert the Answer to ounces.

Ounces = (41/56) * 16 
Ounces = 11.71 ounces  almost 11 3/4
