Answer:
90
Step-by-step explanation:
First of all you have to know that when 2 lines are perpendicular to each other,they produce a 90° angle, therefore DP||TD. Then you should remember that the measure of an arc is the same as the measure of the angle. So angle DB is 90°.

A Choir director made a histogram showing his ages of the members in choir which statement about the data in the histogram must be true
Answers
Answer:
C) The choir has a total of 100 members
Step-by-step explanation:
Histogram is the graphical representation of data with the use of bars of different heights.
From the histogram attached:
A) Number of people fro 46 to 73 years = 30 + 5 + 15 = 50
Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100
Therefore half of the people are from 46 to 73 years.
Therefore the statement that more than half of the people are from 46 to 73 years is wrong.
B) The histogram shows the number of members between each age range, it does not show the number of male and female members. Hence we cannot determine the number of male and female members.
C) Total Number of people = 15 + 20 + 5 + 10 + 30 + 5 + 15 = 100
The choir has a total of 100 members
D) Number of people less than 32 years = 15 + 20 = 35
Therefore the statement that exactly 20 members are less than 32 years is wrong

Answer:
x = 4, y = -3
Step-by-step explanation:
Find the slope intercept form first (y = mx + b):
the one going down is y = -1/2x - 1 (slope is negative, down 1 over 2, and the y-intercept is at (0, -1) )
the one going up is y = 1/4x - 4 (slope is up 1 over 4, and the y-intercept is at (0, -4)
Convert them into standard form (Ax + By = C):
1st equation: multiply the entirety of both sides by 2 to get rid of the fraction:
2y = -1x -`2
add 1x to both sides: 1x + 2y = -2
2nd equation: multiply the entirety of both sides by 4 to get rid of the fraction:
4y = 1x - 16
subtract 1x from both sides: -1x + 4y = -16
Isolate a variable:
-x + 4y = -16
-x = -4y - 16
x = 4y + 16
Plug that into other equation:
1(4y + 16) + 2y = -2
6y + 16 = -2
6y = -18
y = -3
Substitute y into the isolated equation:
x = 4(-3) + 16
x = -12 + 16
x = 4
13. Connie wants to paint one wall in her living room. Along the wall, she
counted 60 pieces of hardwood that are each 6 cm wide. The wall is 8 feet
tall. Estimate the area of the wall she plans to paint. Round to the nearest
square foot. (1 foot approximately 30 cm)
Answers
Answer: Approximately 96 square feet
======================================================
Work Shown:
1 ft = 30 cm
1 ft = (5*6) cm
1 ft = 5*(6 cm)
1 ft = 5*(1 board width)
1 ft = 5 board widths
12*(1 ft) = 12*(5 board widths)
12 ft = 60 board widths
12 ft = 1 full wall length
The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.

Mr. McGill is solving the following problem: 42x=163. Mr. McGill set 2x=3 and got x=32 as his answer. Tell the mistake Mr. McGill made and tell the correct answer.
Answers
Answer:
The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x
Step-by-step explanation:
Given the expression
42x = 163
To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;
42x = 163
42x/42 = 163/42
x = 163/42
x = 3.88
Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

Answers
Answer:
a) 126degrees
b) 47degrees
Step-by-step explanation:
The sum of two supplementary angles is 180 degrees.
Let the other angle be x
x + 54 = 180
x = 180 - 54
x = 126degrees
The supplement is 126degrees
b) The sum of two complementary angles is 90 degrees.
Let the other angle be y
y + 43 = 90
y = 90 - 43
y = 47degrees
Hence the complement is 47 degrees
Consider the system of equations.
3x − y = 5,
2x + 3y = −15
Which value can the first equation be multiplied by to form opposite values on the y-term? A=-3 B= -2 C=2 D=3
The solution to the system of equations is .A= (-5,0) B= (5,0) C= (0,-5) D=(0,5)
Answers
Answer:
D and C
Step-by-step explanation:
Given the 2 equations
3x - y = 5 → (1)
2x + 3y = - 15 → (2)
Multiplying (1) by 3 and adding to (2) will eliminate the y- term
9x - 3y = 15 → (3)
Add (2) and (3) term by term to eliminate y
11x + 0 = 0
11x = 0 ⇒ x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (2)
2(0) + 3y = - 15
0 + 3y = - 15
3y = - 15 ( divide both sides by 3 )
y = - 5
solution is (0, - 5 )

Find the value of x and classify the triangle plzzz
Answers
Answer:
x=24°
The triangle is an obtuse isosceles triangle
Step-by-step explanation:
This is an obtuse isosceles triangle because it has two congruent sides, making it an isosceles triangle, and there is an obtuse angle, which is any angle greater than 90°.
The interior angles of a triangle add up to 180, so let's make an equation.
132+2x=180
Then solve for x
subtract 132 from both sides
2x=48
Divide by 2 on both sides
x=24
