A triangle and its angle measures are shown in the diagram. What is the value of x?
Answers
Answer:
x=16
Step-by-step explanation:
4x - 4 + 0.5x + 32 = 4.5x + 28°
4.5x+28=180° - 80°
We move all terms to the left:
4.5x+28-(100)=0
We add all the numbers together, and all the variables
4.5x-72=0
We move all terms containing x to the left, all other terms to the right
4.5x=72
x=72/4.5
x=16
If my answer is incorrect, pls correct me!

B. 4 squares meter/ = 18 squares/48 meters
C. 1 square/ 4 meters = 48 squares/12 meters
D. 1 square/ 4 meters = 12 square/48 meters
Answers
Answer:
D. 1 square/ 4 meters = 12 square/48 meters
Step-by-step explanation:
You scale down by simplufying the fraction of 12/48. You would divide both 12 and 48 by 12, since it is the highest divisor. And once you divide the two you get 1/4.
Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets: Two solutions: x=2, x=14
Answers
Answer:
Given : equations in the form x−b=c and solution sets
To find : Find expression / equation
Solution:
x−b=c
2 - b = c
13 - b = c
only possible
if | 2 - b| = | 13 - b|
=> 13 - b = b - 2
=> 2b = 11
=> b = 11/2
x - 11/2 = √25
x=23
=> x + 2 = 25
1/2 - b = b + 1/3
=> 2b = 1/6
=> b = 1/12
x - 1/12 = √(25/144)
x = - 3
=> x + 3 = 0
x=−4.1.
=> x + 4.1 = 0
All numbers such that x≥5.
x - 5 ≥ 0
All numbers such that x≤5.
x - 5 ≤ 0
All numbers such that x≤−14.
=> x + 14 ≤ 0
All numbers such that x≥−1.3.
=> x + 13 ≥ 0

For example the age of the Earth (see above) can be written as 4.6 X 109 years. This means that this number has 9 places after the decimal place - filled with zeros unless a number comes after the decimal when writing scientific notation. So 4.6 X 109 years represents 4600000000 years.
Answer:
4.6 × 10⁹
Step-by-step explanation:
I'm not really sure how I would write it down to show how I worked it out.
For me, I usually know in scientific notation, it's usually a decimal number multipled by 10 raised to a certain level of power.
So I just did 4,600,000,000 and turned that into a decimal without its extra zeros, which would be 4.6. Then I worked out how many places the decimal would be from there, which is 9 spaces behind 4.6.

Answer: number 2 is they will each get 3/8 of a pizza
Step-by-step explanation:
this is because if you draw out a circle and take out 1/4 out of it there is 3/4ths left. by knowing this you can see that 3/4ths is not equal for the 2 friends. so for it to be equal we reverse simplify to then make it 6/8ths. there we go, and even number. now we half the 6/8ths to then make it 3/8ths of the pizza for each person.
Answer:
(question 2) 3/8
(question 3.) 16 servings
Step-by-step explanation:
(question 2) 3/4 divided by 2 = (3/4)(1/2)=3/8
(question 3) 6/1 divided by 3/8 = (6/1)(8/3)= 48/3 = 16

A quadratic function models the graph of a parabola. The quadratic functions, y = x2 and y = x2 + 3, are modeled in the graphs of the parabolas shown below.
Determine which situations best represent the scenario shown in the graph of the quadratic functions, y = x2 and y = x2 + 3. Select all that apply.
From x = -2 to x = 0, the average rate of change for both functions is negative
For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function.
The quadratic function, y = x2 + 3, has an x-intercept at the origin
The quadratic function, y = x2, has an x-intercept at the origin
From x = -2 to x = 0, the average rate of change for both functions is positive
For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function.
Answers
Answer:
a. From x = -2 to x = 0, the average rate of change for both functions is negative
d. The quadratic function, y = x², has an x-intercept at the origin
Step-by-step explanation:
From x = -2 to x = 0, the rate of change is negative because both functions are going in a downward slope. The quadratic function y = x² touches the x-axis right at (0, 0), meaning it has an x-intercept at the origin.
The second answer is incorrect because y = x² does not intersect the other parabola at (2, 3). The third is incorrect because y = x² + 3 does not even touch the x-axis. The fifth is incorrect because the rate of change is negative, not positive. Finally, the sixth is incorrect because y = x² + 3 does not intersect the other parabola at (2, 7). Hope this helps!

Answer: x²-22/3x+7/3=0
Step-by-step explanation:
For the solutions to be 1/3 and 7, the equations must be x-1/3 and x-7 because they will equal zero.
(x-1/3)(x-7)=???
x·x= x²
x·(-1/3)=(-1/3x)
x·(-7)=(-7x)
(-7)·(-1/3)=7/3
x²-1/3x-7x+7/3=0 ⇒ x²-22/3x+7/3=0
Since this is in the quadratic form (ax²+bx+c), this is the final answer.

Answers
Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Assuming a total of ten students were asked, [tex]\frac{2}{10}[/tex] chose football and [tex]\frac{8}{10}[/tex] chose other sports. [tex]\frac{2}{10}[/tex] simplified is [tex]\frac{1}{5}[/tex], so that's the experimental chance that the next student favors football.
The experimental probability that the next student Meg talks to will pick football is 1/5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Meg surveyed some students at her school about their favorite professional sports. Of the students surveyed, 2 said football was their favorite sport, while 8 of the students had other favorite sports.
Total number of students surveyed = 8 + 2 = 10
Of the 10 students, 2 said football as their favorite sport.
Probability that a student picks football = 2/10 = 1/5
Hence the probability that the next student picks football is 1/5.
