There are 20 counters in a box. A counter is chosen and replaced 100 times, the results are 32 blue and 68 red. How many of each

krok68 [10]

45/ 360 = 6/x
45x = 2160
x - 2160/45 = 48 people

2)
n = (n - 1) - 5

3)
7x - 11 = 19 - 3x
add 3x to both sides:
10x - 11 = 19
add 11 to both sides:
10x = 30
divide both sides by 10:
x = 30/10 = 3

4)
4(8)(11) - 64 = 288

5)
(5, 0)

6)
-4x -3 + 2x - 6 = -2x - 9

7)
1.8(-20) + 32 = -4F

8)
Exterior angle add to 360
360/6 = 60 degrees

10)
2x/9 = 12
2x = 108
x = 108/2 = 54

11)
x = 0

12)
8 + 3 + 1 = 12
240/12 = 20
8(20) = 160
3(20) = 60
1(20) = 20

160 pounds, 60 pounds, 20 pounds

At a family reunion, Lauren met up with 2 of her cousins; Kali and Allison. She realized that there were 3 generations of cousin

Andrew [12]

Answer:

The age of three girls as

The age of Allison's is 8 years

The age of Kali is 48 years

The age of Lauren's is 24 years

Step-by-step explanation:

Let The age of Allison's = A years

The age of Lauren's = L years

The age of Kali's = K years

Now, According to question

The sum of total ages of the three girl's = 80 years

I.e A + L + K = 80 years

And ,

The age of Allison's = $\frac{1}{3}$ of The age of Lauren's

I.e A = $\frac{1}{3}$ × L

And ,

The age of Kali's = 2 times The age of Lauren's

I.e K = 2 × L

∴ $\frac{1}{3}$ × L + L + 2 × L = 80

Or, $\frac{1}{3}$ L + 3 L = 80

Or, $\frac{10}{3}$ L = 80

So, 10 L = 3 × 80

∴ L = $\frac{240}{10}$

I.e L = 24

The age of Lauren's = 24 years

Again ,

K = 2 × L

Or, k = 2 × 24

∴ k = 48

The age of Kali = 48 years

Similarly

A = $\frac{1}{3}$ × L

Or, A = $\frac{1}{3}$ × 24

∴ A = 8 years

The age of Allison's = 8 years

Hence The age of three girls as

The age of Allison's is 8 years

The age of Kali is 48 years

The age of Lauren's is 24 years Answer

Question 1: Please help, look at the picture below.

NikAS [45]

Answer:

1.98

Step-by-step explanation:

The triangle in the figure is a right triangle, which has a 90 degrees angle.

The side opposite to the right angle is called hypothenuse, and it is the longest side of the triangle.

For a right triangle, the following relationship exists between angles and sides:

$sin \theta = \frac{opposite}{hypothenuse}$ (1)

$cos \theta=\frac{adjacent}{hypotenuse}$

where $\theta$ is any of the other 2 angles in the triangle, and opposite means "side opposite to the angle" and adjacent means "side adjacent to the angle".
