Two angles are supplementary angles if the sum of their measures is 180°.
Find two supplementary angles such that the measure of the first angle is 26° less than
three times the measure of the second.
The measure of the first angle is____ft.
The measure of the first angle is 128. 5 degrees
How to determine the angleFrom the information given, we have that;
The two angles are supplementaryThe sum up to 180 degreesThe first angle is 3x - 26Let the second angle be x
We have the representation as;
3x - 26 + x = 180
collect the like terms, we get;
3x + x = 180 + 26
Add or subtract the like terms
4x = 206
Make 'x' the subject of formula by dividing by the coefficient of x, we get;
x = 206/4

the instructions to mix a cool drink is to use concentrate and water in a ratio 2:9 how much water should be added to 500ml of concentrate
Answer:
2250ml
Step-by-step explanation:
The concentrate-to-water ratio is 2:9. This means 2ml of concentrate requires 9ml of water. We have 500ml of concentrate, which is 250 times more than 2ml, so to find the amount of water, we also multiply 9ml by 250:
2ml concentrate : 9ml water
(Multiply both sides by 250)
500ml concentrate : 2250ml water

Mrs Chong paid for a frying pan that cost $64 with some $10, $5 and $2 notes .If she used a total of 15 notes,how many $5 notes did she use?
Required process!
Thank you
For every $2 note used, Mrs. Chong used 3/5 of a $5 note. Since she used 15 notes in total, and the number of $2 notes used must be an integer, we can see that she used 10 $2 notes. That means she used 3/5 * 10 = 6 $5 notes.
What is Inequalities?
Inequalities are mathematical statements used to express the comparison between two values. Unlike equalities (e.g., 3 + 4 = 7), which use the "equals" sign (=), inequalities use symbols such as "greater than" (>), "less than" (<), "greater than or equal to" (>=), and "less than or equal to" (<=) to express a relationship between the values.
Let's call the number of $10 notes Mrs. Chong used as "x".
We know the total amount she paid was $64, and the number of notes used was 15, so we can set up an equation:
10x + 5y + 2z = 64
Where "y" is the number of $5 notes used and "z" is the number of $2 notes used. We know that x + y + z = 15 (because this is the total number of notes used).
We can substitute x = 15 - y - z into the first equation:
10(15 - y - z) + 5y + 2z = 64
Expanding the equation:
150 - 10y - 10z + 5y + 2z = 64
Combining like terms:
150 - 5y + 3z = 64
Subtracting 150 from both sides:
-5y + 3z = -86
Dividing both sides by -5:
y - (3/5)z = 17.2
So, for every $2 note used, Mrs. Chong used 3/5 of a $5 note. Since she used 15 notes in total, and the number of $2 notes used must be an integer, we can see that she used 10 $2 notes. That means she used 3/5 * 10 = 6 $5 notes.

Let f(x) = x2 − 2x + 1. Find the inverse function of f by identifying an appropriate restriction of its domain.
Answer: [tex]f^{-1} (x) = \sqrt{x} +1[/tex]
Step-by-step explanation:
[tex]y = x^2 - 2x + 1[/tex]
We know straight away the inverse will be a square root function. We also know that this inverse will have a restriction on the domain, (because you can only take the square root of a positive number).
So, to find the inverse, first we'll switch the x and y and solve for y:
[tex]x = y^2 - 2y +1[/tex]
[tex]x = (y-1)^2[/tex], (factor!)
±[tex]\sqrt{x} = y - 1[/tex]
So, the inverse "function" is:
[tex]f^-1(x)[/tex] = ±[tex]\sqrt{x} +1[/tex]
But theres an issue here!
If we tried graphing this, this "function" would not pass the vertical line test, so its not really a function at all!
We need to restrict the domain to only include the values that are above the x axis.
So our final inverse function is:
[tex]f^{-1} (x) = \sqrt{x} +1[/tex]

The height of a triangle is 8 m more than twice the length of the base. The area of the triangle is 21 m². Find the height of the triangle.
Answer:
The height of the triangle is 14 m,
Step-by-step explanation:
Let the base be x, then the height is:
2x + 8The area is half the product of base and height.
Set up equation and solve for x:
x(2x + 8)/2 = 21x(x + 4) = 21x² + 4x = 21x² + 4x - 21 = 0x² + 7x - 3x - 21 = 0x(x + 7) - 3(x + 7) = 0(x + 7)(x - 3) = 0x = - 7 or x = 3The first root is discarded as negative. The second root is the answer.
The base is 3 m, so the height is:
2*3 + 8 = 14 mAnswer:
The height of the triangle is 14 m.
Step-by-step explanation:
The area of a triangle can be found by using the following formula:
[tex]\boxed{A=\dfrac{1}{2}bh}[/tex]
where:
b is the base of the triangle.h is the height of the triangle.If the height of a triangle is 8 m more than twice the length of the base, then an expression for h in terms of b is:
[tex]h = 2b + 8[/tex]
Rewrite this equation to make b the subject:
[tex]\implies 2b=h-8[/tex]
[tex]\implies b=\dfrac{1}{2}h-4[/tex]
Given the area of the triangle is 21 m², substitute this value along with the found expression for b into the formula for area of a triangle:
[tex]\implies \dfrac{1}{2}\left(\dfrac{1}{2}h-4\right)h=21[/tex]
To find the height of the triangle, solve the equation for h.
[tex]\implies \dfrac{1}{4}h^2-2h=21[/tex]
[tex]\implies h^2-8h=84[/tex]
[tex]\implies h^2-8h-84=0[/tex]
[tex]\implies h^2-14h+6h-84=0[/tex]
[tex]\implies h(h-14)+6(h-14)=0[/tex]
[tex]\implies (h+6)(h-14)=0[/tex]
Apply the zero-product property:
[tex]h+6=0 \implies h=-6[/tex]
[tex]h-14=0 \implies h=14[/tex]
As length cannot be negative, the height of the triangle is 14 m.

Say that a certain stadium for professional football has 70,000 seats. What is the shape of the
supply curve for tickets to football games at that stadium? Explain.
Answer: The shape of the supply curve for tickets to football games at the stadium with 70,000 seats is upward-sloping. This means that as the price of tickets increases, the quantity of tickets supplied also increases.
The reasoning behind this is simple: when the price of tickets is high, there is more incentive for the sellers (e.g. the stadium, ticket resellers, etc.) to sell more tickets. They have the ability to supply more tickets as the demand for tickets at the high price is likely to be higher, thus increasing their profits.
However, it is important to note that the upward slope of the supply curve is not necessarily linear. The supply curve for tickets to football games is likely to be more elastic in the higher price range, meaning that as the price continues to increase, the quantity supplied may increase at a slower rate. This is because at some point, even if the price continues to rise, there will be a limit to how many tickets can actually be sold due to a decrease in demand.
Overall, the upward-sloping shape of the supply curve for tickets to football games at the stadium with 70,000 seats reflects the basic principle of supply and demand: as the price increases, the quantity supplied will also increase, but at some point, the increase in price will lead to a decrease in demand, limiting the quantity supplied.

Use the information provided to write the equation of the circle. Center: (-8,11) Radius:2
Use the information provided to write the equation of the circle Center (-8, 11) Radius is 2 is equal to (x + 8)² + (y - 11)² = 4.
What is equation of the circle?
To write the equation of a circle, we need to know its center and radius. If we have the center at point (a, b) and the radius is r, the equation of the circle is:
(x - a)² + (y - b)² = r²
If you have the specific values of a, b, and r, you can plug them into this equation to get the equation of the circle.
The general equation of a circle with center (h, k) and radius r is:
(x - h)² + (y - k)²= r²
Using the given information, we can substitute the values into the equation:
(x - (-8))² + (y - 11)² = 2²
Simplifying, we get:
(x + 8)² + (y - 11)² = 4
Therefore, the equation of the circle with center (-8, 11) and radius 2 is:
(x + 8)² + (y - 11)² = 4
This equation represents all the points that are 2 units away from the center (-8, 11).

For a survey based on 2,700 adults, what is the approximate margin of error? (round your answer to the nearest thousandth.)
The approximate margin of error for a survey based on 2,700 adults, when rounded to nearest thousand is 0.021.
In statistical surveys, the margin of error is a measure of the expected amount of random sampling error that is present in a survey's results. It is a range of values that is likely to contain the true value of the population parameter being estimated, with a certain degree of confidence.
In other words, the margin of error is the amount by which the sample estimate may differ from the true value of the population parameter.
The margin of error is affected by several factors, such as the size of the sample and the level of confidence. A larger sample size typically results in a smaller margin of error because larger samples provide more accurate estimates of the population parameter.
Similarly, a higher level of confidence requires a larger margin of error, since the interval of values that could contain the true population parameter becomes wider as the level of confidence increases.
Assuming a 95% level of confidence, the formula for calculating the margin of error is:
Margin of error = z * sqrt(p * (1 - p) / n)
where:
z is the z-score for the desired level of confidence (1.96 for 95%)
p is the sample proportion, which is the proportion of the sample that exhibits a particular characteristic of interest (e.g., the proportion of respondents who support a certain political candidate)
n is the sample size, which is the number of observations in the sample.
If the sample proportion is not known, it is common to use a value of 0.5, which corresponds to the maximum possible margin of error for a given sample size. This is because the maximum sampling error occurs when the sample proportion is closest to 0.5, which gives the least amount of information about the true population parameter.
To calculate the margin of error for a survey of 2,700 adults, we can assume a sample proportion of 0.5 and a 95% level of confidence. Plugging these values into the formula, we get:
Margin of error = 1.96 * sqrt(0.5 * (1 - 0.5) / 2700)
= 1.96 * sqrt(0.25 / 2700)
= 1.96 * 0.008
= 0.016
Rounding to the nearest thousandth, the approximate margin of error is 0.021. This means that we can expect the survey results to be within plus or minus 2.1 percentage points of the true population parameter, with a 95% level of confidence.

2/6
4/9
Answer:
im pretty sure it is 4/9
Step-by-step explanation:
From the question, we are to determine the probability of selecting two cards with D and D
From the formula for probability, we have that
P(D) = Number of favorable outcomes to D / Total number of possible outcomes
From the given information,
Number of favorable outcomes to D = 2
Number of possible outcomes = 3
Thus,
P(D) = 2/3
Then,
The probability of selecting two cards that have D and D with replacement is
P(D, D) = P(D) × P(D)
P(D, D) = 2/3 × 2/3
P(D, D) = 4/9
Hence, the probability is 4/9.
