Answer:
B
Step-by-step explanation:
sum of angles in a triangle is 180

15n = 180 -105
15n = 75
n= 75/15 = 5
Use intercepts to graph the linear equation 5x + 3y = 30.
Answer x=6 and y=10
Explanation:
Replace each variable in turn with 0 and solve
5x+3y=30 Put zero in place of x and solve for y
5(0)+3y=30
[tex]\frac{3y}{3} =\frac{30}{3}[/tex]
y=10 The y- intercept is 10
5x+3y=30 Put zero in place of y and solve for x
5x+3(0)=30
[tex]\frac{5x}{5} =\frac{30}{5}[/tex]
x=6 The x-intercept is 6
In 2000, the circulation of a local newspaper was 3,250. In 2001, its circulation was 3,640. In 2002, the circulation was 4,100.
A-Find the percent of increase in the newspaper’s circulation from 2000 to 2001 and from 2001 to 2002.
B-Which period had a higher percent of increase, 2000 to 2001, or 2001 to 2002?
Answer:
Percent increase from 2000 to 2001 is 12% and from 2001 to 2002 is 12.6%. Thus period of 2001 to 2002 has higher increase percentage.
Solution:
Given that,
Total circulation of local newspaper in 2000 = 3250
Total circulation of local newspaper in 2001 = 3640
Total circulation of local newspaper in 2002 = 4100
Finding percent of increase in the newspaper’s circulation from 2000 to 2001:
Finding percent of increase in the newspaper’s circulation from 2001 to 2002:
As we can see 12% < 12.6%
So period of 2001 to 2002 has higher increase

What is the centroid of the triangle?In science and math, the centroid of a planar figure or firm figure, also known as the point of intersection or center of the figure, is the mean absolute position of all of the other points on the subject's surface.
The centroid of the triangle is given as,
(x, y) = [(x₁ + x₂ + x₃) / 3, (y₁ + y₂ + y₃) / 3]
Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for △JKL. Then the centroid for △JKL is at point M is given as,
(x, y) = [(7 + 1 + 5) / 3, (8 + 2 + 2) / 3]
(x, y) = (13/3, 12/3)
(x, y) = (13/3, 4)
Then the distance between the point JM is calculated as,
D² = (13/3 - 7)² + (4 - 8)²
D² = 7.1111 + 16
D² = 23.11
D = √23.11
D = 4.81 units
The distance between the point JM will be 4.81 units.

A corner of a rectangle is cut, creating a trapezoid.
What is the value of x?
A. 105°
B. 115
C. 125°
D. 135°
Answer:
the last option of 135°.
Step-by-step explanation:
The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.
90°+90°+45°+x°=360°
225°+x°=360° add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.
x°=135°

Answer:
2
Step-by-step explanation:
(1/2)(6x-2) - 3(x-1)
take the (1/2) and distribute it to the 6x and the 2
(3x-1) - 3(x-1)
next, distribute the 3 to the x and the 1
(3x-1) - (3x-3)
then you simplify
3x-3x cancels
-1 - -3 is the same as -1 +3
so you get 2

Using each picture or description of a triangle, write and solve an equation.
Answer:
Step-by-step explanation:
All angles in a triangle add up to 180º, so we can make this equation.
7x-2+5x-10+4x=180
Combine like terms
16x-12=180
Add 12
16x=168
Divide

Ray earns $15 an hour for up to 40 hours a week. If he works more than 40 hours a week, he is paid time and a half. That means Ray is paid 150% of his hourly wage for every hour he works over 40 hours.
How much additional money does Ray earn for every hour he works over 40 hours?
Last week, Ray worked 46 hours. He incorrectly calculated he earned $45 of additional pay. What was Ray’s error when he miscalculated his overtime pay? Explain your answer.
How much was Ray’s paycheck for working 46 hours? Show your work.
Would Ray make more money working 40 hours a week for two weeks or working 32 hours one week and 46 hours the next? Justify your solution.
For every hour he works over 40 hours, he is paid an additional $7.50.
Ray’s error when he miscalculated his overtime pay is +$45.
How to calculate the error?Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
His normal pay is $15/h
150%/100 = 1.5
Multiply his normal pay by the rate in decimal form;
$15 X 1.5 = $22.5
His OT pay is $22.5/h.
Additional money = (OT pay) - (Normal pay)
= $22.5 - $15
= $7.5
Or $7.5 = $7.50
Thus, For every hour he works over 40 hours, he is paid an additional $7.50.
Ray actual pay for the week was $100 then from the question he incorrectly calculated it as {$100 + $45} = $145 which is $45 above his actual pay.
Error = measured value - actual value.
Error = $145 -$100 =$45.
Since the value $145 is greater than his actual pay $100, we have to include a positive sign to the error $45.
Therefore, Error = +$45.

-6x-2y=42
x-y=-15
Multiply x-y=-15 by 6 ( eliminate the x first)
6(x-y)=6(-15)
(6)(x)=6x
(6)(-y)=-6y
6(-15)=-90
-6x-2y=42
6x-6y=-90
eliminate x the systems of equations by subtracting
-6x+6x-2y+-6y=42-90
-2y-6y=42-90
-8y=-48
divide both sides by -8 to get y by itself
-8y/-8=-48/8
y=6
Find x by substitution method
use y=6 into one of the system of equations
x-y=-15
x-6=-15
