Aiden calculated the area of triangle QRS below by finding half the product of 1.5 and 1.1. Triangle Q R S has a base of 5.4 and

a height of 1.1. Another side has a length of 1.5. What error did Aiden make? Aiden should have found half the product of 1.1 and 1.2 because the 1.5 line is not a dotted line in the figure. Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to the 1.1 line. Aiden should have found half the product of 1.5 and 1.2 because the 1.1 line is not perpendicular to the 1.5 line. Aiden should have found half the product of 1.5 and 5.4 because the 1.1 line is a dotted line and not part of the figure.

The speedometer in Kevin's car reads in both miles/hour and kilometers/hour. What information is needed to convert between these
Akimi4 [234]

Answer:

a) the number of miles in 1 kilometer

Step-by-step explanation:

The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.

So to make the conversion<u> it is enough to know how many miles are in one kilometer.</u>

For example, lets convert 10miles/hour to kilometers/hour.

there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:

\frac{10miles}{hour} (\frac{1kilometer}{0.621371miles} )=16.0934\frac{kilometers}{hour}

Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.
