needless to say that the conversion from miles to kilometers uses a constant value, and therefore, they're directly proportional.

now, I could write the direct proportional relation blah blah but there's no need, we can simply squeeze it out of the table by simply checking how many kilometers there are in 1 mile.

well, we know that 11.0 miles give us 17.699 km, ok hmmm if we divide 17.699 ÷ 11 = 1.609.

if we do the same on table for 26 and 41.834, so 41.834 ÷ 26 = 1.609, and the next pair 54.706 ÷ 34 = 1.609, the value of 1.609 is consistent or constant, or namely that there are 1.609 kilometers in 1 mile.

True or false. There are some parallelograms that are rectangles.

RideAnS [48]

True, because a parallelogram is a four-sided rectangular figure with opposite sides parallel. This is a way to describe a rectangle as well. The only difference is that rectangles must have 90 degree angles, but it is possible for a parallelogram to have 90 degree angles as well. This also means that all rectangles are technically parallelograms as well.

1.The four girls ran in a relay race as a team. If each girl ran one part ofthe race, what was the team’s total time?

natulia [17]

It depends on the total of how long the race took, but each girl ran 1/4 of the race so if you know the total time just divide the time by 4 and you will get the answer. If you don't just say each girl ran 1/4 of the time.

In a market research survey of 2518 motorists, 252 said that they made an obscene gesture in the previous month.

Lelechka [254]

Answer:

Probability is 89.99%

Step-by-step explanation:

divide 252 by 2518 and you get 10.01% but that represents the people who did make the gesture so instead you would minus 252 from 2518 and that would be 252 - 2518 = 2266 then you would divide 2266 by 2518 and you get 2266/2518 = 0.8999 which is equal to 89.99%
