Answer:
1.187991
Step-by-step explanation:
sin^2(225)−(cos(330))(cos(240))
=(−0.930095)2−(cos(330))(cos(240))
=0.865076−(cos(330))(cos(240))
=0.865076−−0.991199(cos(240))
=0.865076−(−0.991199)(0.325781)
=0.865076−(−0.322914)
=1.187991
Answer:
3.5 km
Step-by-step explanation:
We know that 1000 meters = 1 kilometer
500 meters * 1 kilometer/1000m = 500/1000 kilometer = .5 km
He goes .5 km per day
There are 7 days in 1 week, so multiply by 7
7 * .5 km = 3.5 km
Given:
ratio of stickers to erasers: 3 to 8
She has 12 stickers.
3:8 = 12:x
3x = 8*12
3x = 96
x = 96/3
x = 32 erasers.
Mrs. Robbins has 32 erasers.
