If angleA and angleB are vertical angles, and angleA = 38°, find the measure of angleB. A. B = 7° B. B = 57° C. B = 38° D. B = 142°
Answers
This is because vertical angles are congruent
Hope this helps!! :)
Answer:
C. B = 38°
Step-by-step explanation:
A vertical angle is created when two lines intersect, and are a pair of two non adjacent angles that are opposite from the origin, so both angles are going to measure the same.
Since both vertical angles are the same, both measure 38º.
Vertical angles are shown in the image:In this case the angle A would be the omega, and the B is the alfa.

What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that the segment EG is 50 and the ratio of EF to EG is 2 to 5. The length of the segment EF and FG will be calculated as,
EF / EG = 2 /5
EF = ( 2 x EG ) / 5
EF = ( 2 x 50 ) / 5
EF = 2 x 10
EF = 20
The length of the segment FG will be calculated as,
EF / FG = 2 / 3
FG = ( 3 x EF ) / 2
FG = ( 3 x 20 ) / 2
Fg = 3 x 10
FG = 30

One day a store sold 21 sweatshirts. white ones cost $9.95 and yellow ones cost $ 11.50. in all, $235.30 worth of sweatshirts were sold. how many of each color were sold?
Answers
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.

Last year, 1300 procedures were performed on 3900 patient visits. 33% of your patient visits involved a procedure. If you are able to increase that percentage to 45%, what is the number of procedures you will do this year?
Answers
y = number of patient visits
n = % (in decimal form)
Note:
Percentage form = 33%
Decimal form = 0.33
Conversion factor: 1 = 100%
Considering the first statement that 33% or 0.33 is derived from dividing 1300 procedures with 3900 patient visits.Then, our working formula is x/y = n.
If we are ask to increase the percentage to 45% or 0.45, then substitute this value to n in the formula. We subsequently get,
x/y = 0.45
Assuming the patient visits remains the same and substitute it in the formula. We subsequently get,
x/3900 = 0.45
Solving for x. We arrive at an answer of x = 1755 procedures.

In the circle shown below T is the center of the circle, and segments PN and SQ are diameters, and segment PR is tangent to the circle. The measure of angle SQN is 66 degrees
33 degrees
42 degrees
66 degrees
48 degrees
Answers
----------------------------
Use the inscribed angle theorem to get
Minor Arc SN = 2*(angle SQN)
Minor Arc SN = 2*(66)
Minor Arc SN = 132 degrees
----------------------------
Arc PSN is a semicircle so it is 180 degrees, meaning that...
Arc PSN = (minor arc PS) + (minor arc SN)
180 degrees = (minor arc PS) + (132 degrees)
180 = (minor arc PS) + 132
180 - 132 = (minor arc PS) + 132 - 132
48 = minor arc PS
minor arc PS = 48 degrees
central angle RTP = minor arc PS = 48 degrees
----------------------------
Focus on triangle PTR; isolate angle PRT
(angle TPR) + (angle PRT) + (angle RTP) = 180
(90) + (angle PRT) + (48) = 180
(90+48) + (angle PRT) = 180
138 + (angle PRT) = 180
138 + (angle PRT) - 138 = 180 - 138
angle PRT = 42 degrees
----------------------------
----------------------------
Final Answer:
The measure of angle PRT is 42 degrees

A company produces two products, A and B. At least 30 units of product A and at least 10 units of product B must be produced. The maximum number of units that can be produced per day is 80. Product A yields a profit of $15 and product B yields a profit of $8. Let a = the number of units of product A and b = the number of units of product B. What objective function can be used to maximize the profit?
Answers
Let b = units of B produced
At least 30 units of product A and 10 units of product B are required daily, and the maximum number of units per day should not exceed 80.
Therefore
a ≥ 30
b ≥ 10
a + b ≤ 80
Product A yields a profit of $15 and product B yields a profit of $8.
Therefore the objectve profit function is
P(a,b) = 15a + 8b
Answer:
The objective function is
P(a,b) = 15a + 8b, subject to
a >= 30; b>= 10; a+b <= 80
Create a graph that displays the constraints and calculates maximum profit at the boundary points. The solution region is shaded.
The maximum profit occurs when a=70 and b=10.

A total of 518 tickets were sold for the school play. they were either adult tickets or student tickets. there were 68 more student tickets sold than adult tickets. how many adult tickets were sold?
Answers
By setting up two equations based on the total number of tickets and the difference in the number of student and adult tickets, we find that 225 adult tickets were sold for the school play.
To determine the number of adult tickets sold, we can set up two equations based on the information provided. Let A represent the number of adult tickets and S represent the number of student tickets.
The first equation comes from the total number of tickets sold: A + S = 518.
The second equation comes from the additional information about the number of student tickets being greater than adult tickets: S = A + 68.
We can substitute the second equation into the first to solve for A:
A + (A + 68) = 5182A + 68 = 5182A = 518 - 682A = 450A = 450 / 2A = 225Therefore, 225 adult tickets were sold for the school play.

You have a coordinate grid that is 96 x 96. assuming that you encode the x and y coordinate as separate numbers, what is the minimum number of bits that you will need to encode a coordinate in that space?
Answers
To encode a separate x and y coordinate on a 96 x 96 grid, you would need a minimum of 7 bits to represent each coordinate. This is because the nearest power of 2 above 96 is 128, which is 2^7.
Explanation:The subject of this question deals with using binary numbers, or bits, to store data in two-dimensional space, such as with a coordinate grid or a digital image. In this specific case, a coordinate grid with a size of 96 by 96. When encoding the x and y coordinate as separate numbers, we are trying to represent numbers from 0 to 96, so we have 97 different values to represent.
To calculate how many bits you need to store an integer, the question becomes: how many powers of 2 (bits) does it take to store that many different values? The closest power of 2 greater than 96 is 128, which is 2 to the seventh power (2^7). Therefore, you would need a minimum of 7 bits to store a coordinate in that space.

Step-by-step explanation:
5r^2+23r+26=0
The equation cannot factorized
So the general formula would be used
r = [-b +-√(b^2 -4ac)]/2a
a = 5
b =23
c = 26
r =[ -23+-√(23^2-4×5×26)]/2×5
= [-23+-√529-520)]/10
=(-23+-√9)/10
=(-23+-3)/10
r = (-23+3)/10 or r= (-23-3)/10
r= -20/10 or r= -26/10

Which equation correctly applies the distributive property? 2.4⋅(−3.4)⋅(−1.25)=−3.4⋅2.4⋅(−1.25) −2.5⋅(4⋅3.67)=(−2.5⋅4)⋅3.67 (42⋅3.5)+(42⋅1.3)+(42⋅5.2)=42+(3.5+1.3+5.2) −3⋅(6.48)=(−3⋅6)+(−3⋅0.4)+(−3⋅0.08)
Answers
Answer:
The correct equation that applies the distributive property is:
[tex]\[ -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 \][/tex]
Explanation:
The distributive property states that for any real numbers [tex]\( a \), \( b \), and \( c \):[/tex]
[tex]\[ a \cdot (b + c) = a \cdot b + a \cdot c \][/tex]
Let's see which equation correctly applies the distributive property:
1. [tex]\( 2.4 \cdot (-3.4) \cdot (-1.25) = (-3.4) \cdot 2.4 \cdot (-1.25) \)[/tex]
This equation doesn't correctly apply the distributive property. It just switches the order of multiplication, which doesn't demonstrate the distributive property.
2. [tex]\( -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 \)[/tex]
This equation correctly applies the distributive property. It breaks down the multiplication of [tex]\( -2.5 \) and \( (4 \cdot 3.67) \)[/tex] into two separate multiplications.
3. [tex]\( (42 \cdot 3.5) + (42 \cdot 1.3) + (42 \cdot 5.2) = 42 + (3.5 + 1.3 + 5.2) \)[/tex]
This equation doesn't apply the distributive property. It simply adds the products on the left side and compares it to the sum of the terms on the right side, which doesn't demonstrate the distributive property.
4. [tex]\( -3 \cdot (6.48) = (-3 \cdot 6) + (-3 \cdot 0.4) + (-3 \cdot 0.08) \)[/tex]
This equation correctly applies the distributive property. It breaks down the multiplication of \( -3 \) and \( 6.48 \) into three separate multiplications.
So, the correct equation that applies the distributive property is:
[tex]\[ -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 \][/tex]
