we are given

(x,y)=(5,-12)

so, x=5 and y=-12

now, we can find r

r=\sqrt{x^2+y^2}

r=\sqrt{5^2+(-12)^2}

r=13

now, we can find cos

cos(\theta)=\frac{x}{r}

so, we get

cos(\theta)=\frac{5}{13}...........Answer

iogann1982 [59]
The <u>correct answer</u> is:

18.

Explanation:

There were 303 people surveyed total.

There were 64 people with brown eyes and black hair; that makes the percentage of the population 64/303 = 21.12% ≈ 21%.

There were 9 people with blue eyes and black hair; that makes the percentage of the population 9/303 = 2.97% ≈ 3%.

This means the percentage of students with brown eyes and black hair was greater than the percentage of students with blue eyes and black hair by:
21-3 = 18%.

IrinaVladis [17]

4 rows of 7 plants each

To find the number of plants in each row between 5 and 12 requires us to find the factors of the total 28.

28 has factors 1,28 and 2,14 and 4,7. Only 4,7 has a number between 5 and 12. There are 4 rows of 7 plants.

Find out how much you filled.

2.92 + 3.14 = 6.06 L

Find the remaining.

8.23 L - 6.06 L = 2.17 L

You need 2.17 L more to fill the water jug

What's 4+ -1 1/3 as a fraction in simplest form
Ivenika [448]
4 + -1 1/3 

Turn 4 into an improper fraction.

4/4 is equal to 12/3. We want both 4 and 1 1/3 to have the same denominator so that they could be subtracted from each other.

New question :

12/3 + - 1 1/3

Turn {-1 1/3} into an improper fraction.

(3 × 1) + 1  = 4/3

So, -1 1/3 = -4/3

Our new question :

12/3 + - 4/3

Simplify.

12/3 - 4/3 = 8/3

Turn into a mixed number.

2 2/3
