The wind broke a 24 metres high tree. The top of this tree touches the ground. At what height did the tree break if the broken part makes an angle of 30° with the ground?
Answer: The height above ground at which the tree broke is 8 meters.
Step-by-step explanation:
Let the standing part of tree be of 'l' meters.
Therefore the broken part is of 24 - l meters.
By using trignometric functions
sin(30°) =[tex]\frac{Perpendicular}{Hypotenuse}[/tex]
[tex]\frac{1}{2}[/tex]=[tex]\frac{l}{24-l}[/tex]
⇒ 2 × l = 24 - l
⇒3 × l = 24
⇒ l = 8
∴ The height above ground at which the tree broke is 8 meters.

Zeros to the right of a number are significant as long as there is a decimal point present are described the the significance of zeros in a reported number.
Significant Zeros : If a zero is found between significant digits, it is valid. If the number is decimal, zeros can be used as placeholders (meaningless) to the left of significant digits. For example, if the mass is 32 g, there are 2 significant digits. Expressed in kilograms, the mass of 0.032 kg should have two significant digits. The zeros to the right of the decimal point that are not just placeholders are significant. These significant zeros are to the right of any significant non-zero digits. The zeros to the left of the 20.00 cm decimal point are also significant, as they are among the significant digits. If a decimal point is present, all digits from the first non-zero digit (to the right) are significant. If there is no decimal point, trailing zeros are considered insignificant unless scientific notation makes the quantity clear.
Start on the left and move right until you reach the first non-zero number..

At Laura' ummer camp, there were 200 boy and 16 counelor. At thi rate, how many boy hould be at camp with 20 counelor?
With 20 counselors, there should be 250 boys at Laura's summer camp.
To determine how many boys should be at camp with 20 counselors, we can use the proportion of boys to counselors that existed at the camp when there were 200 boys and 16 counselors.
The proportion of boys to counselors when there were 200 boys and 16 counselors is 200/16 = 12.5 boys per counselor.
If we want to know how many boys should be at camp with 20 counselors, we can use this proportion and the number of counselors we have (20) to calculate the number of boys.
To calculate this, we can use the following formula:
Number of boys = (Proportion of boys to counselors) x (Number of counselors)
So for 20 counselors, the number of boys should be:
12.5 x 20 = 250 boys
So with 20 counselors, there should be 250 boys at Laura's summer camp.

Arianna is working two summer jobs, washing cars and tutoring. She must work no less than 10 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, ww, and the number of hours tutoring, tt, that Arianna can work in a given week.
Let ww represent the number of hours washing cars, and tt represent the number of hours tutoring.
The inequality representing the total number of hours Arianna must work between both jobs is:
ww + tt ≥ 10
This inequality states that the number of hours spent washing cars plus the number of hours spent tutoring must be greater than or equal to 10 hours. This represents all possible combinations of hours washing cars and hours tutoring that Arianna can work in a given week while meeting the requirement that she must work no less than 10 hours altogether between both jobs.

Let the C.P. be Rs x. If a shopkeeper makes 12% loss by selling a watch for Rs 484, find C.P.
Answer:
To find the cost price (C.P.) of the watch, we need to use the following formula:
C.P. = Selling Price / (1 - Loss Percentage)
In this case, we know that the Selling Price is Rs 484 and the Loss Percentage is 12%. To use this formula, we first need to convert the Loss Percentage to a decimal:
12% = 0.12
Now we can plug in the values into the formula:
C.P. = 484 / (1 - 0.12)
Solving for C.P., we get:
C.P. = 484 / 0.88
C.P. = Rs 550
Therefore, the cost price (C.P.) of the watch is Rs 550.

Justify your answer. (c) This type of bird can also be found in another state. Suppose the distribution of the weight for birds in the other state is approximately normal. A bird with a weight of 13 ounces is at the 70th percentile. Interpret the percentile in context. If the standard deviation is 2 ounces what is the mean weight of this type of bird in the state?
A bird with a weight greater than 13 ounces lives in the southern region
Z = (x – mean)/standard deviation
Le x be weight for birds
For the northern region
Z = (13 – 10)/3
Z = 1
For the southern region
Z = (13 – 16)/2.5
Z = -1.2
to find in what region is more likely to find a bird with 13 ounces, we calculate the probability for each z value
For the northern region
P (x>13) = P(z > 1)
Then we use the z table to find the area under the curve.
P (x>13) = 0.1587
For the southern region
P (x>13) = P(z > 1.2)
Then we use the z table to find the area under the curve.

One side of a rectangle is 20cm longer than another side. If you double the length of the shorter side and triple the length of the longer side, then the perimeter of the new rectangle will be 240cm. Find the lengths of the sides of the original rectangle.
Answer:
The length of the short side was 12 and the length of the long side was 32
Step-by-step explanation:
We will say that the length is the shorter side, and be using l as the variable, and that width is the longer side, and be using w as the variable. The first two equations we have are:
w = l + 20
And
2(2l + 3w) = 240
We will start with the second equation, then substitute in the first equation for w. We have:
4l + 6w = 240
Divide both sides by 2:
2l + 3w = 120
Then, we substitute in l + 20 for w, giving us:
2l + 3l + 60 = 120
Subtract 60 from both sides and combine like terms:
5l = 60
l = 12
So, the original length was 12, now substituting this into our first equation gives us:
w = 12 + 20 = 32
So the original width was 32. So, the length of the short side was 12 and the length of the long side was 32.

What are examples and probability?
The quantity of success-producing options. the total number of outcomes that could occur.
For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one way to acquire a head and there are a total of 2 possible outcomes (a head or tail). We specify P(heads) = 12.
0.05x0.6302 1!(10-1)! =10x0.05x0.6302 = 0.3151 ">
Since the binomial distribution is a discrete distribution, it accepts discrete random variables. This shows that the random variable x can only accept integer values and cannot take the value 0.5000 because it is on an interval scale (continuous). Therefore, the statement that the maximum probability happens when x equals 0.5000 is false.

A parabola's vertex is its minimum or maximum point. The vertex is the smallest point and the parabola widens upward if a>0. Vertex is maximal point and parabola widens downward if a=0.
You must ascertain the x and y coordinates in order to determine the vertex.
The equation for the vertex's x-coordinate and the axis of symmetry is:
[tex]$x=\frac{-b}{2 a}[/tex]
To find the y-coordinate of the vertex, substitute the value for x into the equation and solve for y.
[tex]$y=a\left(\frac{-b}{2 a}\right)^2+b\left(\frac{-b}{2 a}\right)+c[/tex]

What is the slope of the line that passes through (2, 1) and (2, -9)?
explain on how you got the answer
Answer:
Hi!
slope of a line passing through the point (2,1) and (2,-1)
as you can see the abscisas of the point is same which means x-axis
now by formula
m = slope y2-y1/x2-x1
-9-1/2-2
-10/0 when there's zero in denominator this mean answer is infinity ♾️
This mean line is parallel to Y-axis
so when we're hanging out
Answer: the slope is undefined
Step-by-step explanation:
Slope = y2-y1 divided by x2-x1
slope = -9 - 1 divided by 2 - 2
slope = -10 divided by 0
Any slope with 0 as the denominator is always undefined.
Calculate the difference between your estimate in part a and the actual value you calculated in part b. be sure to show this solution as an equation. based on this difference do you think your estimate for part a was reasonable? explain.
The difference between the estimate in part a and the actual value calculated in part b is the equation (Estimate - Actual Value). In this case, the equation is (50 - 41.2) = 8.8.
What is equation?An equation is a mathematical statement that two expressions are equal. It is usually written using an equal sign (=) and may also include numbers, variables, operators, and other mathematical symbols. Equations are used to describe relationships between different values, such as the area of a circle or the slope of a line. Equations can be used to solve for a single unknown value, or to find the relationship between different values.
Given that the difference between the estimate and actual value is 8.8, I think my estimate was reasonable. This is because the difference between the estimate and actual value is relatively small, which suggests that my estimate was close to the actual value. Therefore, my estimate was reasonable.

Why is 1 a unique number?
One is a unique number as it is only a positive integer that is neither prime nor composite.
If the numeral is a positive integer and there are no duplicate digits, it will be considered unique. The fact that one is the only positive integer that is neither prime nor composite makes it a unique number. It is the only positive integer that can be divided by each other and itself. As a result, only one can be regarded as the lowest common denominator among all other integers.
Given that it is the identity element for multiplication, every integer multiplied by one equals the original number. Additionally, it is the additive identity element, which means that any integer plus one equals itself. Every number may be stated as a power of one, which is the foundation of the number system.
