Step-by-step explanation:
Triangle ABC has the angle measures shown.
Which statement is true about the angles?
mzA=20°
mzA=(2x)
m2 = (5x)"
m2 = (11)
mZB=60
Aand 2B are complementary
OmZA+mZC=120
Answer:
m∠A = 20°
Step-by-step explanation:
Triangle ABC has the following angle measures:
m∠A = 2x°m∠B = 5x°m∠C = 11x°We know that the addition of the angles of a triangle makes 180°, therefore:
m∠A + m∠B + m∠C = 180°
Replacing with data and solving for x:
2x + 5x + 11x = 180
18x = 180
x = 180/18
x = 10°
Which makes the angles:
m∠A = 2*10 = 20°
m∠B = 5*10 = 50°
m∠C = 11*10 = 110°

What are the chances of choosing a black marker out of a bag containing 3 red markers, 5 blue markers, 3 yellow markers, and 4 black markers? What is the probability of choosing two black markers if the first marker is put back before the second is drawn?
Answer:
[tex]\dfrac{16}{225}[/tex].
Step-by-step explanation:
It is given that,
Number of red markers = 3
Number of blue markers = 5
Number of yellow markers = 3
Number of black markers = 4
Total markers = 3 + 5 + 3 + 4 = 15
Probability of getting a black marker is
[tex]P(Black)=\dfrac{\text{Number of black markers}}{\text{Total markers}}[/tex]
[tex]P(Black)=\dfrac{4}{15}[/tex]
Probability of choosing two black markers if the first marker is put back before the second is drawn, is
Required probability [tex]=P(Black)\times P(Black)[/tex]
[tex]=\dfrac{4}{15}\times \dfrac{4}{15}[/tex]
[tex]=\dfrac{16}{225}[/tex]
Therefore, the probability of choosing two black markers if the first marker is put back before the second is drawn, is [tex]\dfrac{16}{225}[/tex].

Barika, Akeelah, and James raised $76.23 for their dance team. James raised twice as much as Barika, who earned 2.60 less than Akeelah. If x = the amount raised by Akeelah, choose the expressions that represent the amount each other player raised. x – 2.60 2x + 5.20 .5x + 2.60 2x – 5.20
The amount raised by Akeelah is x, by Barika is x- 2.60, and by James is 2x- 5.20.
If we analyze it via steps,
We first take the value we know, that is the amount raised by Akeelah that is x. So if Barika is 2.60 less than Akeelah we will numerically express the equation as x-2.60.
Then we look at the amount raised by James it says that it is twice as much as Barika, we numerically express that as
2(x- 2.60) = (2.x) - (2 . 2.60) = 2x -5.20 (simpler form)
If we want to find out the amount we can even do so by adding the amount raised by Barika, Akeelah, and James. We numerically express that as x + (x-2.60) + (2x-5.20) . This equation will be equal to the total value given as the amount raised by all three which is $76.23.
So, By the Problem,
x + (x-2.60) + (2x-5.20) = 76.23
=> 4x - 7.80 = 76.23
=> 4x = 68.43
=> x = 68.43/4
=> x = 17.11
Therefore, Akeelah raised x = $17.11
Barika raised x-2.60 = $14.51
James raised 2x -5.20 = $29.02

The perimeter of an equilateral triangle must be at most 57 feet. Create an inequality to find
what the length of the sides should be. Solve the inequality by showing all of your work.
We know that the perimeter is at most 57 feet. We will call the length of each side with the variable 'x'. Each side is the same since it's an equilateral triangle.
The perimeter of the triangle is defined as '3x' because 3 times the side length of an equilateral triangle is its perimeter.
Since the perimeter is at most 57 feet, it can't be more than that. Therefore, we get the inequality 3x≤57.
This inequality is the same as saying the perimeter is less than or equal to 57 feet.
Now we solve.
3x≤57
Isolate 'x': 3x/3≤57/3
0<x≤19 is our answer.
The reason there is a "0<" added is because the side of a triangle can't be less than 0, that would be impossible.

What is the measure of angle B in degrees? A triangle has angles A, C, 51 degrees. Angle A has exterior angle B and angle C has an exterior angle with measure of 112 degrees. °
Step-by-step explanation:
The angle adjacent to 112° will form a straight angle along with 112° adding to 180°. That makes C: 68°
a+c+51 = 180
a+68°+51° = 180°
a+119° = 180°
a = 180° - 119°
a = 61°
a+b = 180°
61+b = 180
b = 180-61
b = 119°
The measure of angle B is 119 degrees.
What is Exterior angle?Exterior angle is an measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
All the exterior angles are of same measure, and therefore, their measure is (360/n)°.
The angle adjacent to 112° will form a straight angle along with 112° adding to 180° which makes angle C: 68°
Then;
a+c+51 = 180
a+68°+51° = 180°
a+119° = 180°
a = 180° - 119°
a = 61°
Now,
a+b = 180°
61+b = 180
b = 180-61
b = 119°

y
0.25
0.125
0.0625
0.03125
O 0.5
O 0.75
Answer:
Every time x increases by 1, y is multiplied by 0.5. That is the multiplicative rate of change.
Step-by-step explanation:
Well, I am not sure whether this is your question, but I kind of arranged the values into a more clear table.
x 1 2 3 4
y 0.25 0.125 0.0625 0.03125
To find the rate of change, you want to find what can be multiplied by the y-value to get another y-value as the x-value increases.
For example, you can see that when x is 1, y is 0.25. When x increases by 1, y is 0.125.
0.125 / 0.25 = 0.5. That means that when x increases by 1, y is multiplied by 0.5. You can check this by multiplying the rest of the values and seeing whether they match.
0.125 * 0.5 = 0.0625
0.0625 * 0.5 = 0.03125
Since the pattern continues, you can be sure that the multiplicative rate of change for y is 0.5.
The multiplicative rate of change of the exponential function is 0.5
From the table, we have the following representations
x 1 2 3 4
y 0.25 0.125 0.0625 0.03125
Divide yn by yn-1, to calculate the multiplicative rate (r) of change of the function
So, we have:
[tex]r = \frac{y_n}{y_{n - 1}}[/tex]
Let n = 2.
So, we have:
[tex]r = \frac{y_2}{y_{2 - 1}}[/tex]
This gives
[tex]r = \frac{y_2}{y_1}[/tex]
Substitute values for y2 and y1
[tex]r = \frac{0.125}{0.25}[/tex]
Divide
[tex]r = 0.5[/tex]
Hence, the multiplicative rate of change of the function is 0.5

Write the following Arithmetic sequence using an Explicit Formula: a1 = 8, an = an-1 -2
Answer:
an = 8 - 2*(n - 1)
Step-by-step explanation:
a1 ; .... ; an-1 ; an
r = an - an-1
r = (an-1 - 2) - an-1
r = an-1 - 2 - an-1
r = -2
So:
an = a1 + r*(n - 1)
an = 8 + (-2)*(n - 1)
an = 8 - 2*(n - 1)
The nth term of the arithmetic sequence using the explicit formula will be [tex]a_{n}[/tex] = 8 - 2(n - 1) thus option (A) is correct.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
As per the given,
First term a₁ = 8
[tex]a_{n} =a_{n-1}-2[/tex]
The common difference between the AP will is,
d = [tex]a_{n} -a_{n-1}[/tex]
d = -2
The nth term of an AP is given as a + (n - 1)d
Thus,
[tex]a_{n}[/tex] = 8 + (n - 1)(-2)
[tex]a_{n}[/tex] = 8 - 2(n - 1)
Hence "The nth term of the arithmetic sequence using the explicit formula will be [tex]a_{n}[/tex] = 8 - 2(n - 1)".

Suppose your allowance is $2 now, and it will
double every week. Write an exponential expression for your allowance 20 weeks from
now. Then use your calculator to calculate your allowance at that time.
An exponential expression to represent your allowance 20 weeks from now would be:
2^20
This is correct since we are basically multiply 2 by itself for twenty times.
Now, we solve it.
2^20 = 1048576
Thus, your allowance by the end of 20 weeks is $1,048,575.
