Answer: C

Step-by-step explanation:

y = mx + b

Genrish500 [490]

Answer:

28. (H) 24 ft

30. (F) \frac{5}{52}

Step-by-step explanation:

28. A right triangle can be formed, where the length of the cable represents the hypotenuse, and the ground represents the base of the triangle. From the pythagorean theorem,

a^2 + b^2 = c^2

where a and b are legs, and c is the hypotenuse of a right triangle.

So

18^2 + b^2 = 30^2\\b = \sqrt{30^2 - 18^2}\\b = \sqrt{576}\\b = 24

30. The probability of drawing a red 1 is \frac{2}{52} (a red star 1 or a red heart 1), the probability of drawing a black 3 is \frac{2}{52} (a black triangle 3 or a black circle 3), and the probability of drawing a six of hearts is \frac{1}{52} (since there is only one six of hearts in the entire deck). Since each of the cards is mutually exclusive from one another, the probability of drawing any of them is simply all of their probabilities added together. That is,

\frac{2}{52} + \frac{2}{52} + \frac{1}{52} = \frac{5}{52}

4. You work in the upholstery department of a furniture factory.
Wewaii [24]

Answer:

a. $1360

b. $8.50 per hour

Step-by-step explanation:

a.

5 couches upholstered, each 105 equals 5 * 105 = 525

6 loveseats upholstered, each 85 equals 6 * 85 = 510

5 chairs upholstered, each 65 equals 5 * 65 = 325

Hence, total pay = 525 + 510 + 325 = $1360

b.

To find hourly rate, we take total amount and divide it by number of hours.

1360/160 = $8.5 per hour

Hence, hourly rate is $8.50 per hour
