first convert 0.88 to degrees

so arcsin(0.88) = 61.642 degrees

Arcsin on a calculator is sin^-1

then to convert to radians divide degrees by 180 and multiply that by PI

so (61.642/180) x PI = 1.076 radians

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.

HELP!!!! I need help

ahrayia [7]

Answer:

1 Tenths = 10 Hundredths

10.74 - 10.60 = 0.14

0.14 = 14 hundredths

Thus, you need 10 ones, 6 tenths and 14 hundredths to make 10.74.
