Answers
Answer:
y = 110 degree
x = 70 degree
z = 70 degree
Step-by-step explanation:
Vertical angles are always congruent.
so, the angle with the 110 degree is equal to the angle y.
now we have the measure of y.
as you can see angle y and angle z form a straight light wich means the sum of angle y and angle x is 180 degree
now, to get the measure of angle z,
180 - 110 = angle z
70 = angle z
now we have the measure of angle z
as angle z and angle x are vertical angle, they are congruent.
so angle x = 70
x = 70
z= 70
y = 110

You have $300. Your sister has at most $50 less than you. Write an inequality that matches the situation. Give an amount of money your sister could have.
Answers
So 300-50 =250 thats the best scenario, because 50 is most that can be subtracted. (Example, Instead of 50 it can be 40 but not 60. If 40, it becomes 260 so more than if subtracted by 50.)
So,

At Central High School, there are 48 football players and 20 cheerleaders. What is the ratio of cheerleaders to football players?
Answers
Answer:
The answer should be 5:12.
Step-by-step explanation:
Since the question asks what's the ratio of cheerleaders to football players, the ratio before simplifying would be 20:48.
So, just find the greatest common divisor of 20 and 48, which would be 4.
20/4 = 5
48/4 = 12
Therefore, the answer to this question and the ratio of cheerleaders to football players is 5:12.

Answer:
Step-by-step explanation:
This quadratic equation is given in standard form, which is [tex]y= ax^2 +bx+c[/tex]. The x-value of the vertex of a quadratic equation can be found using the given formula. Therefore, we can plug the the numbers given into the formula as such: [tex]x=\frac{24}{2(6)}[/tex]. This can be simplified into 2. Now that we have the x-coordinate, we can plug that back into the equation to find the y-coordinate: [tex]y=6(2)^2-24(2)+30[/tex]. This simplifies to y = 6. Therefore, the vertex of the equation is located at (2,6).

Answers
Answer:
91,300 to 3 s.f.
Step-by-step explanation:
The population is reduced by a percentage 100-7 = 93% ( or 0.93) per year.
So after 5 years thatwould be 300,000(0.93)^5
= 208707
that is 300,000 - 208,706
= 91293
= 91,300 to 3 s.f.

The red arrow represents an outlier in the given dot plot. which the correct answer would be an option (A).
What is the dot plot?A dot plot, sometimes known as a dot chart, is a sort of basic histogram-like graphic used in statistics for very small data sets with discrete values.
An outlier is a value in a random sampling from a population that is significantly different from the other values. In some ways, this definition leaves it up to the analyst (or a consensus process) to determine what is abnormal. Normal observations must first be characterized before anomalous observations may be identified.
The dot plot is given in the question,
According to the given dot plot,
Most data are clustered around [12, 14], while 24 is distant from this interval.
Thus, the red arrow represents an outlier in the given dot plot.
Hence, the correct answer would be option (A).

(LCM) of 28, 42 and 63
Answers
Answer:
252
Step-by-step explanation:
The least common multiple is the product of all factors in the greatest number of their occurrence.
LCM = 2 x 2 x 3 x 3 x 7
LCM = 2^2 x 3^2 x 7
LCM = 252
The least common multiple of 28, 42 and 63 is 252.
Answer:
LCM = 252.
Step-by-step explanation:
First find their prime factors:
28 = 2*2*7
42 = 2*3*7
63 = 3*3*7
So, only including like factors once, LCM =
2*2*3*3*7

Answers
Answer:
x = 5
Step-by-step explanation:
x + 4 = 3(x - 2) ← distribute parenthesis by 3
x + 4 = 3x - 6 ( subtract 3x from both sides )
- 2x + 4 = - 6 ( subtract 4 from both sides )
- 2x = - 10 ( divide both sides by - 2 )
x = 5
Answer:
Solution of equation is 5Step-by-step explanation:
In the question we have given an equation that is x + 4 = 3 ( x - 2 ) . And we are asked to solve the question that means we have to find the value of x .
Solution : -
[tex] \longrightarrow \quad \: x + 4 = 3(x - 2)[/tex]
Step 1 : Solving parenthesis on right side :
[tex] \longrightarrow \quad \: x + 4 = 3x - 6[/tex]
Step 2 : Subtracting 4 on both sides :
[tex] \longrightarrow \quad \: x + \cancel{4} - \cancel{ 4 }= 3x - 6 - 4[/tex]
On further calculations we get :
[tex] \longrightarrow \quad \: x = 3x - 10[/tex]
Step 3 : Subtracting 3x on both sides :
[tex] \longrightarrow \quad \: x - 3x = \cancel{3x } - \cancel{3x}- 10[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: - 2x = - 10[/tex]
Step 4 : Dividing both sides by -2 :
[tex]\longrightarrow \quad \: \dfrac{ \cancel{ - 2}x}{ \cancel{ - 2} } = \cancel{\dfrac{ - 10}{ - 2} }[/tex]
On further calculations we get :
[tex]\longrightarrow \quad \: \red{\underline\red{\boxed{ \frak{ x = 5}}}}[/tex]
Therefore , value of x is 5 .Verifying : -
We are verifying our answer by substituting value of x in given equation. So ,
x + 4 = 3 ( x - 2 )5 + 4 = 3 ( 5 - 2 )9 = 3 ( 3 )9 = 9L.H.S = R.H.S Hence, Verified.Therefore, our answer is correct .
