k = 10

Using trigonometric ratio then;

sin30 = opp/hyp

0.5 = 5/k

cross multiply

0.5k = 5

Divide both sides by 0.5

k = 5/0.5

k=10

Simora [160]

Answer:

1=(w=6,C=20.80

2=(W=2,C=27.05)

3=(w=11,C=14.25)

4=(w=15,C=11.05)

Step-by-step explanation:

Just do the work

0.55x15=8.25+2.80=11.05

1.10x6=6.6+14.20=20.8

11x0.65=7.15+7.10=14.25

Out of process of elimination, 2=(W=2,C=27.05)

Answer:

Mean: 58

Median: 58

Step-by-step explanation:

The mean is a type of average. It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are.
The median is the middle number; found by ordering all data points and picking out the one in the middle

FINDING THE MEAN:

57 + 54 + 59 + 57 + 61 + 58 + 60 = 406

406 ÷ 7 = 58

FINDING THE MEAN:

Arrange the numbers from smallest to greatest:

54, 57, 57, 58, 59, 60, 61

Find the median number:

54, 57, 57, 58, 59, 60, 61

The median is: 58

-138≥-6(6b-7)║ what is the value of b?

Keith_Richards [23]

-138 ≥ -6(6b - 7)

Start by multiplying everything within the parentheses by -6.

-138 ≥ -36b + 42

Now move the +42 to the other side, so you're left with -36b. (You do this by subtracting 4242)

-138 - 42 ≥ -36b

-180 ≥ -36b

Divide both sides by -36 to find the value of b.

-180 / -36 ≥ b

5 ≥ b.

The answer is b ≤ 5.
