Answer:
The answer to your question is:
a) sinФ = -4/√17
b) cosФ= 1/√17
c) tanФ = -4
Step-by-step explanation:
Just draw a right triangle where the opposite leg is -4/√17 the adjacent leg is 1/√17 and the hypotenuse is 1.
then sine Ф = opposite / hypotenuse = -4/√17 / 1 = -4/√17
cosine Ф = adjacent /hypotenuse = 1/√17 / 1 = 1/√17
tan Ф = opposite / adjacent = -4/√17 / 1/√17 = -4/1
Since 1 kilogram equals 1,000 grams 5 potatoes equals 1,000 grams. 1,000 divided by 5 is 200. This means 1 potato has a mass of 200 grams 1,200 divided by 8 is 150. that means a pear has a mass of 150 grams. Since 200 grams is bigger then 150 grams, that means the potato has greater mass>

30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
Answer:
22.5
Step-by-step explanation:
Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:
13.5 / 0.6 = 22.5
22.5 x 0.6 = 13.5
