Let (2x-12) degrees represent the measure of an acute angle. What are the possible values of x?

Answers

Acute angle is an angle measure less than 90 degrees
 Right angle is an angle that measure 90 degrees
Obtuse angle is an angle that measure more than 90 degrees.

In the given situation, we need to find the value of x of an acute angle with the given situation
=> (2x-12)
=> 0 < (2x -12) < 90
=> 12 < 2x < 102
=> 6 < x < 51

Let’s check our answer
=> 2 (51- 6)
=> 102 – 12
=> 90
Thus, the value of x = 51 degrees

(02.02 HC)Andrew makes $6 an hour plus $9 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.

Part A: Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime. (3 points)

Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours. (3 points)

Part C: Andrew earned $330 in 1 week. How many hours (regular plus overtime) did he work? (4 points)

Answers

A) 6x=W
B)(6 x 40) + 9y = s
   240 + 9y = s
C) 240 +9y = 330
     9y = 90
     y=10

Andrew worked 40 hours plus 10 hours of overtime.
He worked a total of 50 hours

Kaylee has already prepared 3 kilograms of dough and will continue preparing 8 kilograms of dough every hour. How many hours did Kaylee work if she prepared 35 kilograms of dough?

Answers

Answer:

4 hours

Step-by-step explanation:

In order to solve this problem, you need to write down the equation. The equation is 3 +8x=35. In this equation, x represents the number of hours. The coefficient is 8, and that represents the number of kilograms per hour. You subtract 3 from both sides to get 32. Next, we solve for x. Divide both sides by 8 to get x=4 hours.
