The value of x is 22. The angle the flagpole makes with the ground, represented as 3x+24∘, is supplementary to the angle the flagpole makes with the vertical line, which is 90 degrees. By setting up the equation 3x+24° + 90° =180°. and solving for x, we find =22. Thus, the flagpole makes a 3(22) + 24° + 90° =180° angle with the ground.
Certainly, let's break it down step by step:
Given: The angle the flagpole makes with the ground is [tex]\(3x + 24^\circ\).[/tex]
1. **Define the problem**: Let [tex]\( \theta \)[/tex] represent the angle the flagpole makes with the ground.
2. **Write the given information**:
[tex]\[ \theta = 3x + 24^\circ \][/tex]
3. **Understand the geometric situation**: The angle formed by the flagpole with the ground is supplementary to the angle formed by the flagpole with the vertical line
4. **Write the equation based on the supplementary angles relationship**:
[tex]\[ \theta + 90^\circ = 180^\circ \][/tex]
5. **Substitute the given value of [tex]\( \theta \)[/tex]**:
[tex]\[ (3x + 24^\circ) + 90^\circ = 180^\circ \][/tex]
6. **Simplify the equation**:
[tex]\[ 3x + 24^\circ + 90^\circ = 180^\circ \][/tex]
7. **Combine like terms**:
[tex]\[ 3x + 114^\circ = 180^\circ \][/tex]
8. **Isolate \(x\)**:
[tex]\[ 3x = 180^\circ - 114^\circ \][/tex]
[tex]\[ 3x = 66^\circ \][/tex]
[tex]\[ x = \frac{66^\circ}{3} \][/tex]
[tex]\[ x = 22 \][/tex]
[tex]So, \( x = 22 \).[/tex]
#1 Find the slope given the points (3,-20) and (5,8) *
Hey there :)
To find the slope with two points we will need to use the equation [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
[tex]x^1[/tex] [tex]x^2[/tex] [tex]y^1[/tex] [tex]y^2[/tex]
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (it will be a fraction) :
[tex]\frac{8 - (-20)}{5 - 3}[/tex]
We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get [tex]\frac{28}{2}[/tex]
28 divided by 2 is 14. The slope is 14.

Step-by-step explanation:
Ivanna is playing a game in which she spins a spinner with 6 equal-sized slices numbered 1 through 6. The spinner stops on a numbered slice at random.
This game is this: Ivanna spins the spinner once. She wins $1 if the spinner stops on the number 1, $3 if the spinner stops on the number 2, $5 if the spinner stops on the number 3, and $7 if the spinner stops on the number 4. She loses $8 if the spinner stops on 5 or 6.
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
The question is a probability problem in Mathematics. It requires calculating the expected value of a game based on the potential winnings and losses and their respective probabilities. On average, Ivanna will lose a dollar each time she plays.
Explanation:The subject matter of this question is a probability problem within Mathematics. One way to approach the problem would be to calculate the expected value of Ivanna's winnings from a single spin of the spinner. Each outcome (1, 2, 3, 4, 5, 6) has an equal chance of being chosen, which is 1/6, because there are 6 equally likely outcomes.
The formula for the expected value is the sum of all potential outcomes multiplied by their respective probabilities. Numerically, this would be (1*$1 + 1*$3 + 1*$5 + 1*$7 - 2*$8) / 6, which equals -$1.
Therefore, on average, Ivanna will lose a dollar each time she plays this game.

X^2-x-20 how do I write that in factored form
Answer:
(x+4)(x-5)
Step-by-step explanation:
You need to find two numbers that multiply to be -20 but add up to be -1.
Answer:
( x - 5 ) ( x + 4 )
Step-by-step explanation:
When solving quadratic equations it's important to remember that they have 2 solution. We need to work out the factors, sum and the products to successfully factorise the quadratic and solve it. So,
x² - x - 20 = 0
Sum = -1
Product = -20
So we need two numbers that sum to -1 and multiply together to make -20
Factors = -5 and 4
x² - 5x + 4x - 20
Factor x² - 5x and 4x -20 separately
x² - 5x = x ( x - 5 )
4x - 20 = 4 ( x - 5 ) So
x ( x - 5 ) + 4 ( x - 5 )
We can see a common factor of ( x - 5 ) and the other bracket would be ( x + 4)
( x - 5 ) ( x + 4 )

A group of friends were working on a student film that had a budget of $500. They used $25 of their budget on props. What percentage of their total budget did they spend on props?
The students spent 5% of their $500 budget on props, calculated by dividing $25 by $500 and then multiplying by 100.
To determine the percentage of the total budget that was spent on props for the student film, we need to use the formula for calculating percentages. The formula is
(amount spent / total budget)
* 100 = percentage spent.
Applying this formula to the given values:
(25 / 500) * 100 = 5%.Therefore, the students spent 5% of their total budget on props.
Find the volume of the cone
Answer:
Step-by-step explanation:
slant height l = 14cm
r = 6 cm
Use Pythagorean theorem.
h² + 6² = 14²
h² + 36 = 196
h² = 196 - 36
h² = 160
h = √160
h = 12.65 cm
[tex]Volume=\frac{1}{3}\pi r^{2}h\\\\=\frac{1}{3}*3.14*6*6*12.64\\\\[/tex]
= 476.61 cubic cm
Answer:
The volume of cone is 476.61 cm³.

Ali picked three numbers out of a hat. Use the information in the box to work out what numbers he picked. The lowest number was 11;the range was 13; the median was 17. Write All numbers in the boxes from lowest to highest
Final answer:
To find the numbers Ali picked, we identify the lowest number (11), calculate the highest number using the range (11 + 13 = 24), and confirm that the median (17) fits between these two numbers. Thus, the numbers are 11, 17, and 24.
Explanation:
Ali picked three numbers, and we have been provided with three pieces of information about these numbers: the lowest number was 11, the range was 13, and the median was 17. We can use this information to determine the three numbers Ali picked.
Step 1: Identify the Lowest Number
We know the lowest number is 11. This is our starting point.
Step 2: Determine the Range
The range of a set of numbers is the difference between the highest and the lowest numbers. Since the range is 13, we add this to the lowest number to find the highest number: 11 + 13 = 24. So, the highest number Ali picked is 24.
Step 3: Find the Median
The median is the middle number in a set of numbers that has been arranged in order. We are told the median is 17, which fits perfectly between our lowest and highest numbers, confirming that our calculations are correct.
Therefore, the numbers Ali picked, in order from lowest to highest, are: 11, 17, and 24.
if a scientist is able to use 4 kilograms of fertilizer for 5 weeks how much fertilizer did they use each week
Answer:
0.8 kilograms of fertilizer
Step-by-step explanation:
Looking at the data given to us in a fraction form, we can imagine:
4 kilograms / 5 weeks
To find out how many kilograms of fertilizer was used each week, we're going to divide that fraction out, so we're going to do 4 divided by 5. Dividing this will give you:
0.8 kilograms
Therefore your answer is that they use .8 kilograms of fertilizer each week.

Takiya recorded the heights of two sets of plants, one set planted in the shade and one set planted in full sun. Her data are shown in the plots below.
A dot plot. A number line going from 1.5 to 4.5 in increments of 0.5 is labeled Heights of Shaded plants (inches). There are 0 dots above 1.5, 4 above 2, 3 above 2.5, 2 above 3, 0 above 3.5 and 4, and 1 above 4.5.
A dot plot. A number line going from 1.5 to 4.5 in increments of 0.5 is labeled Heights of Full Sun plants (inches). There are 0 dots above 1.5, 1 above 2, 0 above 2.5, 2 above 3, 0 above 3.5, 4 above 4, and 3 above 4.5.
Which best explains the variability of the sets?
The shaded plants set has greater variability because more data is clustered around the median.
The sets are equally variable because the ranges of the data sets are equal.
The full sun plants set has greater variability because the IQR for full sun plants is greater.
Question;
1) The shaded plants set has greater variability because more data is clustered around the median.
2) The sets are equally variable because the ranges of the data sets are equal.
3) The full sun plants set has greater variability because the IQR for full sun plants is greater.
Answer:
The correct option is;
3) The full sun plants set has greater variability because the IQR for full sun plants is greater
Step-by-step explanation:
To answer the question, we present the dot plot as follows;
Heights of Shaded plants (inches)
0 4 3 2 0 0 1
0 1.5 2 2.5 3 3.5 4 4.5
We calculate the five numbers as follows;
Max = 4.5
Min = 2
1st quartile = (10+1)/4 th term = 2
2nd quartile (Median) = (10+1)/2 th term = 2.5
3rd quartile = 3×(10+1)/4 th term = 3
Interquatile range (IQR) = Q₃ - Q₁ = 3 - 2 = 1
Where:
Q₁ = 1st quartile
Q₃ = 3rd quartile
Heights of Full Sun plants
0 1 0 2 0 4 3
1.5 2 2.5 3 3.5 4 4.5
We calculate the five numbers as follows;
Max = 4.5
Min = 2
1st quartile = (10+1)/4 th term = 3
2nd quartile (Median) = (10+1)/2 th term = 4
3rd quartile = 3×(10+1)/4 th term = 4.5
Interquatile range (IQR) = Q₃ - Q₁ = 4.5 - 3 = 1.5
The interquartile range, IQR, is a measure of variability
Therefore, the full sun plants set has greater variability because the IQR for full sun plants is greater.

Suppose $1750 is put into an account that pays an annual rate of 4.5%
compounded quarterly. How much will be in the account after 6 years?(round to the
hundredth place)
Answer:
There will be $2288.98 in the account after 6 years
Step-by-step explanation:
We are given that $1750 is put into an account that pays an annual rate of 4.5% compounded quarterly.
So, Principal = $1750
Rate of interest = 4.5%
No. of compounds per year = 4
Time = 6 years
Formula :[tex]A =P(1+\frac{r}{n})^{nt}[/tex]
Where A = Amount
P = Principal
r = rate of interest
n = no. of compounds per year
t = time
Substitute the values in the formula :
[tex]A =1750(1+\frac{4.5}{400})^{4 \times 6}[/tex]
A=2288.98
Hence There will be $2288.98 in the account after 6 years
