1 kg is 1,000 grams.
200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.
Thus 200 g= 1/5 kg = 0.2 kg.
1 kg of cheese is <span>$4.40,

so 0.2 kg of cheese is
Answer: $0.88
You have to divide 300 with 15, the answer to that is: 300/15=20. However, if she starts saving this week (counting as a first), she will have enough money in 19 weeks after the first week, she needs 20 weeks to save the money.
You can use the identity
cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.
(1/4)² +sin(x)² = 1
sin(x)² = 1 - 1/16
sin(x) = ±(√15)/4
Then the tangent can be computed as the ratio of sine to cosine.
tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
tan(x) = ±√15
There are two possible answers.
In the first quadrant:
sin(x) = (√15)/4
tan(x) = √15
In the fourth quadrant:
sin(x) = -(√15)/4
tan(x) = -√15
Answer:
p/q = -5/25
multiply-25/5 × -5/25 You'll get the answer as 1.
