In this problem we need to use the property of a inscribed angle:
The inscribed angle is a point in the circle that has endpoints also in the circle. The value of the inscribed angle is half the value of the arc formed by the endpoints.
So, If the arc FJ is 84°, we have that the angle in point G isi 84/2 = 42°
solve the simultaneous equations

A coffee maker priced at $189.99 is on sale for 20% off but then sales tax of 9% and 8% are added to the price after discount. What will be the final sale price with taxes?
RIGHT ANSWER WILL BE MARKED BRAINLIEST
Answer:
20%+9%+8%=37% so 189.99*37/100=70.3$ so 189.99-70.3=119.7$
The final sale price of the coffee maker with taxes is $178.03.
How to calculate the final sale price?To find the final sale price of the coffee maker with taxes, we need to first calculate the discount and then add the tax amounts to the discounted price.
The discount on the coffee maker is 20/100 × $189.99 = $37.998.
So the price of the coffee maker after the discount is:
$189.99 - $37.998 = $152.992.
Then, we need to add the sales tax amounts to this price.
The sales tax amounts are 9/100 × $152.992 = $13.7993
And 8/100 × $152.992 = $12.23936.
The total tax amount is $13.7993 + $12.23936 = $26.03.
Therefore, the final sale price of the coffee maker with taxes is :
$152.992 + $26.03866 = $178.03
This is the final price that the customer will pay for the coffee maker.

what are the coordinates of A after reflecting across the line x = 3? (2, 3)
(3, 2) (3, 4) (3, -2)
Answer:
Here we can not see point A, so i will answer in a general way.
Let's suppose that point A is (a, b)
Now, if we do a reflection over a given line, the (perpendicular) distance between our original point to the line is the same as the distance between the reflected point and the line.
So for example if we have the point (x, y) and we do a reflection over the line x = k.
The distance between our point and the line is:
x - k
So the new point must be also at a distance of (x - k) from line x = k.
The only other point that meets this condition is (k - (x - k), y) = (2k - x, y)
Now remember that point A is (a, b)
And we do a reflection over x = 3
The distance between our point and the line is:
D = I(a - 3)I
Then the reflection will be:
(3 - (a - 3), b) = (6 - a, b)
Where (a, b) where the original coordinates of point A.

All the members of a school chorus are either students or employees.The ratio of students to employees is 2:5 and the chorus has 70 members. How many employees are members of the chrous?
Answer:
50 employees are members of the chorus
Step-by-step explanation:
Total number of chorus members = 70
ratio of students to employees = 2:5
This means that if the total number of employees were to be divided into 7 parts (2 + 5), 2 parts will be students while 5 parts will be employees. Now let us convert this fraction/ratio to numbers. This is done as follows:
students to employees = 2:5
∴ employees to students = 5:2
Total parts of employees and students = 5 + 2 = 7
∴ Number of employees
[tex]= \frac{5}{7}\ of\ 70\\= \frac{5}{7} \times \frac{70}{1}\\= \frac{350}{7} = 50\ members[/tex]
∴ 50 members are employees, while the remaining 20 are students
Write in slope intercept form.
15x − 4y = 11
Answer:
y = 15/4x - 11/4
Step-by-step explanation:
Slope-intercept form of the line 15x - 4y = 11 is y = (15/4)y + 11/4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in slope-intercept form is y = mx + b.
∴ 15x − 4y = 11 can be written as - 4y = - 15x + 11 ⇒ y = (15/4)y + 11/4.

The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55

Answer:
The equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
Step-by-step explanation:
Let x be the cost of 11 rubbers.
As the cost of 5 rubber stamps is $9.70.
Thus, the cost of 11 rubbers can be determined using the proportional ratios.
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
BONUS! let us solve to check
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
switch sides
[tex]\frac{x}{11}=\frac{9.7}{5}[/tex]
Multiply both sides by 11
[tex]\frac{11x}{11}=\frac{9.7\cdot \:11}{5}[/tex]
Simplify
[tex]x=21.34[/tex]
Thus, the cost of 11 rubber stamps: x = $21.34
Therefore, the equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
VERIFICIATIONGiven
The cost of 5 rubber stamps = $9.70
Thus,
The cost of 1 rubber stamps = 9.70 / 5
= $1.94
If the cost of 1 rubber stamp = $1.94
The cost of 11 rubber stamps = 11 × 1.94
= $21.34

What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answer:
Balance = $195.56
Step-by-step explanation:

Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck
