Answer:
Rocco mowed 1 lawn a week.
Step-by-step explanation:
If Carly mowed 18 lawns in six weeks that’s 3 lawns a week and 3-2=1.
Thus Rocco mowed 1 lawn a week.
First we want to find how much it costs for 1 stamp, so we do 8.28 divided by 18, which equals 0.46. Then, we multiply 0.46 and 12, which is 5.52. Therefore, it would cost $5.52 to buy 12 stamps.
Answer:
Step-by-step explanation:
Rule
The sin of any angle = cos(90 - the angle used for the sine)
Sin(64) = cos(90 - 64)
Sin(64) = cos(26)
Check
Sin(64) = 0.8988
Cos(26) = 0.8988
The sum of the measures of complementary angles equals 90 °
