Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)

Step-by-step explanation:
Since you have 12 numbers in order, that's an even number, once you put them in numerical order and start crossing them off on both sides, you'll have 18 and 24 left, add them together and divide them by 2 and you'll have your median 21.

write a quadratic function h whose zeros are - 6 and -5 h (x) =
Answers
Answer:
h(x)= x^2+11x+30
Step-by-step explanation:
A quadratic function is in the form h(x) = ax^2 + bx + c.
Since the zeros are -6 and -5, take the opposite signs and add them to the variable x separately.
It should look like this: h(x)= (x+6)(x+5)
Since this is the factored form, we have to solve this equation further.
h(x)= (x+6)(x+5)
h(x)= x^2+6x+5x+30
h(x)= x^2+11x+30

Answer:
[tex]q = 22[/tex]
Step-by-step explanation:
The angle measure of a straight line is (180) degrees As given in the picture, line (AC) is a straight line, thus its angle measure is (180) degrees. Angles (ABD) and (DBC) make up line (AC). Therefore, one can conclude that the sum of angles (ABD) and (DBC) is (180) degrees. Form an equation, simplify and use inverse operations to solve for the unknown parameter (q).
[tex](<ABD) + (<DBC) = (AC)[/tex]
Substitute for the angle measures,

the area of a circle is 100 square miles. What is the diameter?
Answers
Answer:
The diameter of a circle with an area of 100 square miles is 20/√π miles.
Step-by-step explanation:
Area =100 = πr^2.
diameter = d = 2r.
100 = πr^2.
100/π = r^2.
√(100/π) = r.
10/√π = r.
d = 2r.
d = 2 * 10/√π.
d = 20/√π

replacement?
3) What is the (P) quarter then a dime, with
replacement?
4) What is the (P) nickel then a nickel, without
replacement?
Answers
Answer:
Step-by-step explanation:
To calculate the probability of drawing a nickel followed by a quarter without replacement, we need to determine the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes: Ricky chooses 2 coins from a total of 3 quarters, 5 dimes, and 2 nickels. This can be calculated using combinations, denoted as C(n, r), which represents the number of ways to choose r items from a set of n items. In this case, Ricky is choosing 2 coins from a set of 10 coins:
Total possible outcomes = C(10, 2) = 45
Number of favorable outcomes: Ricky needs to select a nickel first, which leaves 9 coins remaining. Out of these remaining coins, there is 1 quarter. Thus, the number of favorable outcomes is 1.
Favorable outcomes = 1
Probability (P) of drawing a nickel then a quarter without replacement:
P = Favorable outcomes / Total possible outcomes
P = 1 / 45
Therefore, the probability of selecting a nickel followed by a quarter without replacement is 1/45.
To calculate the probability of drawing a nickel then a dime with replacement, we assume that after each selection, the coin is replaced, and the total number of coins remains the same.
Probability (P) of drawing a nickel then a dime with replacement:
P(nickel then dime) = (Number of nickels / Total number of coins) * (Number of dimes / Total number of coins)
P(nickel then dime) = (2/10) * (5/10)
P(nickel then dime) = 1/10
Therefore, the probability of selecting a nickel followed by a dime with replacement is 1/10.
To calculate the probability of drawing a quarter then a dime with replacement:
Probability (P) of drawing a quarter then a dime with replacement:
P(quarter then dime) = (Number of quarters / Total number of coins) * (Number of dimes / Total number of coins)
P(quarter then dime) = (3/10) * (5/10)
P(quarter then dime) = 3/20
Therefore, the probability of selecting a quarter followed by a dime with replacement is 3/20.
To calculate the probability of drawing a nickel then another nickel without replacement, we need to consider that the second draw must be a nickel and that the first nickel is not replaced.
Total number of possible outcomes: Ricky chooses 2 coins from a total of 3 quarters, 5 dimes, and 2 nickels:
Total possible outcomes = C(10, 2) = 45
Number of favorable outcomes: Ricky needs to select a nickel first, which leaves 9 coins remaining. Out of these remaining coins, there is only 1 nickel left.
Favorable outcomes = 1
Probability (P) of drawing a nickel then another nickel without replacement:
P = Favorable outcomes / Total possible outcomes
P = 1 / 45
Therefore, the probability of selecting a nickel followed by another nickel without replacement is 1/45.

He makes $8.14 for each hour he works, and on average earns an additional $300 per week in tips. Which function, f(x), can Leo use to model his average weekly salary in terms of the number of hours, x, he works?
Answers
Answer:
f(x) = 8.14x + 300
Step-by-step explanation:
The function of 8.14x + 300 can be used to model Leo's average weekly salary in terms of x.
What is a function?' A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.'
According to the given problem,
Amount Leo earns for each hour he works = $8.14
Amount Leo earns in x hours = $8.14x
Amount Leo earns as additional tip per week = $300
Therefore, the function of x is,
⇒ f(x) = 8.14x + 300
Hence, we can conclude, the function that can be used to model his weekly salary is 8.14x + 300

Answer: CANNOT make a triangle
b] 5 ft, 7 ft, 11 ft
sum of shorter sides is (5+7)=12
since 12 is greater than 11, then the three length can make a triangle.
Answer: CAN make a triangle

Para hacer 600 m de una obra, 30 obreros han trabajado 12 dias a razon de 10 horas diarias. ¿Cuantos dias necesitaran 36 obreros para hacer 900 m de la obra trabajando 6 horas diarias?
Answers
Respuesta:
25 días
Explicación paso a paso:
Dado :
escenario 1
Área = 600 m
Número de días = 12
Número de trabajadores = 30
Tasa = 6
Escenario 2:
Área = 900 m
Número de días = n
Número de trabajadores = 36
Tasa = 6
Igualar los parámetros en cada escenario:
12 / n = 36/30 * 6/10 * 600/900
12 / n = 6/5 * 3/5 * 2/3
12 / n = 6/5 * 1/5 * 2/1
12 / n = 12/25
12 * 25 = 12n
300 = 12n
n = 300/12
n = 25 días
The number of days that 36 workers need at the given rate is 25 days
From the given question, we have 2 scenarios
First case:
Distance worked = 600mNumber of workers = 30 workersDays of wors = 12 daysRate per day = 10 hours per daySecond case:
Distance worked = 900mNumber of workers = 36 workersDays of wors = n daysRate per day = 6 hours per dayTaking the ratios of the distance worked, the number of workers, and rate will give:
12/n = 36/30 * 6/10 * 600/900
12/n = 129600/270000
Cross multiply;
129600n = 12 * 270000
129600n = 3240000
n = 3240000/129600
n = 25
Hence the number of days that 36 workers need at the given rate is 25 days
