Answer:
D. 15Step-by-step explanation:
First find the value of x:
3x - 16 + 6x + 7 = 180 (supplementary angles)9x = 189x = 21Find the value of y:
11y - 32 = 6x + 7 (vertical angles)11y - 32 = 6*21 + 711y = 32 + 13311y = 165y = 165/11y = 15Correct choice is D

Step-by-step explanation:
A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solution?
Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
Answer:
50 grams

John's salary last year was $80000. Last year he got a raise of 10%. This year the company lost money and his salary was cut back to $80000. By what percent did his salary decrease this year?
Answer:
9.09%
Step-by-step explanation:
John Salary = $80,000.
Raise = 10% of salary = 10/100*80,000=$8000
New Raised Salary = 80000 + 8000 = $88000
Cut back = 80000
Decrease % = (88000-80000)/88000*100
Decrease % = 8000/88000*100
Decrease % = 9.09%

Find the measure of angle x in the figure.
Answer:
x = 124°
Step-by-step explanation:
The polygon given is a 7-sided polygon with 7 interior angles.
Sum of all 7 interior angles of the polygon = (n - 2)*180, where n = 7, we would have the following equation:
131° + 131° + 126° + 118° + 134° + 136° + x° = (7 - 2)*180
776 + x = 900
Subtract 776 from each side
x = 900 - 776
x = 124°
Answer: 123
Step-by-step explanation:
The equation: (n-2)180

Jane corporation produces model toy cars each sells for $29 99 sense its variable cost per unit is $14 25 sense what is the break even point for Jane corporation assuming it has a fixed cost of $314800
Answer:
Break-even point in units= 20,000
Step-by-step explanation:
Giving the following information:
Selling price per unit= $29.99
Unitary variable cost= $14.25
Fixed costs= $314,800
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 314,800 / (29.99 - 14.25)
Break-even point in units= 20,000
