Answer: B) 38
Step-by-step explanation:
1) [tex]x+(x+6)+(3x-16)=180[/tex] (sum of angles in triangle)
2) [tex]5x-10=180[/tex] (Algebra)
3) [tex]5x=190[/tex]
4) x= 38 degrees
Answer: x = 38
Step-by-step explanation:
1) Add 3x - 16 and x + 6 and x together. You get 5x - 10.
2) All sides of a triangle equals 180 degrees, so that means 5x - 10 = 180.
3) Add 10 to both sides, 5x = 190.
4) 190/5 = 38
5) 38 is your answer.

Step-by-step explanation:
The local newspaper has letters to the editor from 10 people. If this number represents 4% of all of the newspaper's readers, how many readers does the newspaper have?
Answer:
The local newspaper has 250 readers in total
Step-by-step explanation:
Given that
Letter to the editor = 10
Also it is given that 10 is the 4% of total readers of the newspaper.
Let x be the number of readers of the newspaper
It can be written as:
[tex]10 = 4\%\ of\ x[/tex]
Converting the percentage into decimal
[tex]10 = 0.04x\\\frac{10}{0.04} = \frac{0.04x}{0.04}\\x = 250[/tex]
The newspaper has 250 readers.
Hence,
The local newspaper has 250 readers in total
Mary is going to have an outdoor party in 10 days. She wants to have her backyard pond covered in water lilies before the party, so she goes to the nursery to buy some water lilies. Mary gives the clerk the dimensions of her pond, and the clerk, knowing the growth rate of the water lilies that he stocks, calculates that if she purchases a single water lily, it will produce a population of ten thousand lilies that will completely cover the surface of the pond in 20 days. Mary reasons that if she buys two water lilies instead of one, she can meet her goal of having the pond surface covered in 10 days. Is there anything wrong with Mary's reasoning? How many water lilies will Mary need to buy to meet her goal?
Answer:
a. There is nothing wrong with Mary's reasoning b. 2 water lilies.
Step-by-step explanation:
a. This is because, she reasons that if she doubles the amount of water lilies she buys, it would take half the time it takes to produce 10,000 lilies. So, there is nothing wrong with Mary's reasoning.
b. Since it takes 1 water lily to produce 10000 lilies in 20 days, 1 water lily will produce x lilies in 10 days.
So, x = 10000 × 10/20 = 5000 lilies
So, 1 water lily produces 5000 lilies in 10 days.
So, x water lilies will produces 10000 lilies in 10 days.
So x = 10000 × 1/5000 = 2 water lilies
So, 2 water lilies will produce 10000 lilies in 10 days.
So, Mary needs 2 water lilies so she can meet her goal of having the pond surface covered in 10 days.

To find the area of a rectangle, multiply the length and the width.
The length of a rectangle is (X - 6) and the width of the rectangle is (x - 10). What is the area of the rectangle?
Answer:
Step-by-step explanation:
area = length * width
area = (x - 6) (x - 10)
area = x (x - 10) - 6 (x - 10)
area = x^2 -10x -6x -10
area = x^2 -16x -10

A group of 5 friends went out to dinner. The total bill including the tax and tip came to $83.95. If they split the bill evenly, how much money does each person owe?
Answer:
Each person owes $16.79
Step-by-step explanation:
The total including tax was 83.95. Divide this by the 5 people to get 16.79.
The money that does each person owe should be $16.79.
Calculation of the money:Since A group of 5 friends went out to dinner. The total bill including the tax and tip came to $83.95.

How do you know whether two quantities x and y are proportional?
1. Every ratio yx for related pairs of x and y is equivalent.
2. Every sum x + y is the same for related pairs of x and y.
3. Every x term is a multiple of the previous term.
4. Every difference x – y is the same for related pairs of x and y please help me
Answer:
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.
For two quantities y and x when we say that both are proportional then t can be written as:
y∝x
Removing the proportionality symbol introduces a constant which is the ratio of y and x.
[tex]\frac{y}{x} = k[/tex]
This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.
Hence,
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.

Select all of the descriptions which describe a transformation of the graph of f(x)=x that could result in
the graph of g(x) = 2x.
A. The graph is translated 2 units to the right.
B. The graph is rotated about (0,0), becoming steeper.
C. The graph is vertically stretched.
D. The graph is translated 2 units up.
E. The graph is vertically shrunk.
F. The graph is reflected across the x-axis.
Answer:
The descriptions that apply are E and F.
Step-by-step explanation:
Let's graph both functions, attached the result:
A: No. The graph is not reflected across x-axis. For this to happen, there should be a negative sign: g(x) = -x, for example
B: No, the graph doesn't translate. The graph only translates if there is: g(x) = a(x-c)+b, where b defines the vertical translation, and c the horizontal one.
C: No. This would happen for g(x)=x/2, for example.
D: No. Check the explanation of B.
E: Yes. The graph rotates due to the factor of 10. This rotation only applies for straight lines.
F: Yes. It stretched.

Which of the following is the best interpretation of the expected value?
A. Each day, 3 customers will order the daily special.
B. Over many days, the average number of customers ordering the daily special is approximately 2.86.
C. Over many days, it takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
D. For a random sample of the days, the average number of orders of the daily special will be 2.86.

What Is a Random Variable?A random variable is a variable whose value is unknown or a function that assigns values to each of an experiment's outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or continuous, which are variables that can have any values within a continuous range.
Given here: The distribution of X is geometric and has an expected value of approximately 2.86. And 35 percent of the customers order the daily special each day. Thus clearly the correct and precise interpretation of the statement is Over many days, It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.

The dimensions of a rectangular prism are 24 ft x 20 ft x 15 ft. What is the surface area
Answer:
2280 ft^2
Step-by-step explanation:
A rectangular prism has 6 faces. Each pair of opposite faces is congruent.
surface area = 2LW + 2LH + 2WH
surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)
surface area = 960 ft^2 + 720 ft^2 + 600 ft^2
surface area = 2280 ft^2

If a gun fires 88 rounds per minute, how many rounds would it fire in 45 minutes?
Answer:
3960
Step-by-step explanation:
1minute = 88rounds
45minutes = xrounds
1/45 = 88/x
45(88)= 3960
3960/1 = 3960
x = 3960
The gun fires 3960 rounds in 45 minutes.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Let x rounds would it fire in 45 minutes
As per the situation, we can write the proportion would be as:
1 minute : 88 rounds = 45minutes : x rounds
⇒ 1/88 = 45/x
Apply the cross-multiplication, and we get
⇒ x = 45(88)
⇒ x = 3960
This means a gun fires 3960 rounds in 45 minutes.

Answer:
The correct answer to the question is;
1 < x < 4
Step-by-step explanation:
The give parameters are;
ΔABC is an isosceles triangle, with the vertex angle = 35° + 20° = 55°
Therefore, the two base angles are 62.5° each by definition of isosceles triangle
Given that the angle subtended by 4·x - 4 which is 25° is lesser than the angle subtended by the 12 unit side length which is 35° we have;
4·x - 4 < 12
4·x < 12 + 4
∴ 4·x < 16
x < 16/4
x < 4
Therefore, the range is 1 < x < 4

Write an equation in slope-intercept form for the line with slope 7 and y-intercept -8.
Answer:
y = 7x - 8
Step-by-step explanation:
The equation of a line in slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept.
The problem already gives us both of these values:
m = 7
b = -8
All we have to do is plug them in:
y = mx + b
y = 7x + -8
y = 7x - 8
Thus, the answer is y = 7x - 8.
