Answer:
93
Step-by-step explanation:
A + B +C = 180
75+51 + C =180
126 +C =180
C = 180-126 = 54
DCB : ACD = 2:1
DCB = 2x
ACD = x
2x+x=54
3x = 54 ; x = 54/3 = 18
DCB = 2x = 2 x 18 = 36
dcb + dbc + bdc = 180
51 + 36 + bdc = 180
87 + bdc = 180 ; bdc = 180 - 87 = 93
I hope im right!!
Answer:
the answer is 93°
Step-by-step explanation:
As you know that in a triangle,
angle1+angle2+angle3 = 180°
hence,
angle ABC + angle BAC + angle DCB + angle ACD ( Angle DCB + angle ACD = angle BCA) = 180°
75°+51°+2x+1x (let the ratio be x) = 180°
126°+3x = 180°
3x = 54°
x = 18°
2x = 36° = angle DCB
In triangle DCB,
51°+36°+angle BCD = 180°
angle BCD = 180°- 87°
Hence, angle BCD = 93°

The school that Maria goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 12 student tickets for a total of $51. The school took in $93 on the second day by selling 5 senior citizen tickets and 6 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Cost of Senior Citizen Ticket: $
Cost of Student Ticket: $
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
Step-by-step explanation:
Let the price of a senior citizen ticket be s.
Let the price of a student ticket be t.
Day 1:
s + 12t = 51
Day 2:
5s + 6t = 93
The system of equations is:
s + 12t = 51
5s + 6t = 93
Let's use the substitution method to solve it. Solve the first equation for s.
s = 51 - 12t
Now substitute s in the second equation with 51 - 12t.
5s + 6t = 93
5(51 - 12t) + 6t = 93
255 - 60t + 6t = 93
Subtract 255 from both sides. Combine -60t and 6t.
-54t = -162
Divide both sides by -54.
t = 3
Now substitute 3 for t in the equation
s = 51 - 12t
s = 51 - 12(3)
s = 51 - 36
s = 15
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3

May someone please help me out? Just do 1 and I just need steps because I’m unfamiliar with this.
Answer:
x=5.09
Step-by-step explanation:
Always look at what info they give you, here you have angle, opposite, and adjacent. The trig function that uses [tex]\frac{opp}{adj}[/tex] is tangent so tan (27) = [tex]\frac{x}{10}[/tex] so
x = 10 tan (27) so x = 10 (.5095254495) [make sure you are in degree mode] so x has to be 5.09
The same goes for question 10, check what you are given [hint: you will need sin probably]....good luck!

The angles x°, 2x°, and (x + 10)° are complementary angles. Then the value of the variable x will be 20°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
The angles x°, 2x°, and (x + 10)° are complementary angles.
Then the sum of the angles x°, 2x°, and (x + 10)° will be 90°.
Then the equation will be
x° + 2x° + (x + 10)° = 90°
Simplify the equation, then the value of x will be
4x + 10 = 90
4x = 80
x = 20°
Thus, the value of the variable x will be 20°.

Answer:
20 is the anwser for this problem
The number of medium bags will be 410 / 3.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags
The equation can be written as,
L + M + S = 440
L = 2M
2M + M + 30 = 440
3M = 410
M = 410 / 3
Therefore, the number of medium bags will be 410 / 3.

Micah wants to know the most common style of surfboard used at Breakers Point. He surveys surfers at Breakers Point between 8:00 A.M. and 12 P.M. Which of the following statements is true about Micah’s survey? Select all that apply.
A. Micah will obtain a random sample by talking to as many surfers as possible.
B. The population for the survey is all people who surf at Breakers Point.
C. Micah will not get a representative sample.
D. Micah's sample will be representative because anyone can surf at Breakers Point
Answer: B I think I hope it helps
Step-by-step explanation:
The statements that are true are:
The population for the survey is all people who surf at Breakers Point.Micah will not get a representative sample.What is random sampling?It is a method of selecting a set number of essential items from a given population.
Each item has an equal likelihood of getting chosen.
A. Micah will interview as many surfers as possible to obtain a random sample.
This statement is not always true because Micah may not be able to speak with all of the surfers at Breakers Point during the time frame specified. Also, randomly selecting surfers would result in a more accurate picture of the population.
B. The survey's population consists of all Breakers Point surfers.
This remark is correct, as the demographic of interest at Breakers Point is surfers.
C. Micah will not be able to obtain a representative sample.
This assertion is also correct, as the poll is only done between 8:00 a.m. and 12:00 p.m., which may not be representative of all Breakers Point surfers.
Furthermore, if Micah only polls surfers in a specific place or time period, the sample may be biased.
D. The statement is not always true because not all surfers surf at the same time or location, or have the same level of experience or surfboard preference.

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
One angle is 26 degrees and the other is 64 degrees.
Step-by-step explanation:
Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:
90 = (x-38) + (x)
52 = 2x
26 = x
This means that one of the angles is 26 degrees, and the other is 64 degrees.

The total interest on a 5 year 5.2% loan with a principal of $10,000 is 10,000 × 0.052 × 5 = $2,600.
True or False?
Answer:
True
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.2%/100 = 0.052 per year,
then, solving our equation
I = 10000 × 0.052 × 5 = 2600
I = $ 2,600.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 5.2% per year
for 5 years is $ 2,600.00.
