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.

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.

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.

So, theta = arctan(sqrt(500^2-d^2) / d) would give us the angle between the ground and the ladder where d is distance from the base of the ladder to the building.

The angle between the ground and the ladder can be found using the inverse tangent function (also known as arctan) and the Pythagorean theorem.

First, we need to find the ratio of the height of the ladder to the distance from the base of the ladder to the building. This ratio is known as the tangent of the angle between the ground and the ladder.

Let h be the height of the ladder and d be the distance from the base of the ladder to the building.

tan(theta) = h/d

Next, we can use the Pythagorean theorem to find the value of h:

d^2 + h^2 = 500^2

Now we can substitute the value of h in the first equation.

tan(theta) = sqrt(500^2-d^2) / d

To find the angle between the ladder and the ground, you can use the inverse tangent function on the above equation.

theta = arctan(sqrt(500^2-d^2) / d)

To find the exact value of the angle, you would need to know the value of d (distance from the base of the ladder to the building).

Since 4x2+1 cannot equal 0, the solution to the above expressions issue indicates that (4x20+1) has no real factors.

It is necessary to substitute a number for each variable and conduct arithmetic operations in order to verify an algebraic equation. The response variable in the example above is comparable to 6, as 6 plus 6 = 12. Knowing the values of the variables will enable us to replace the original values with those known, allowing us to evaluate the expression.

It is significant to remember that the current ratio of a term's coefficient

Words 8x3 and 2x have a coefficient ratio of 8:2 (4:1), whereas phrases 12x2 and 3 have a coefficient ratio of 12:3 (4:1) This implies that the original sentence should be divided into the following categories: This indicates that the original phrase, which is written as, should be combined as follows:

duri will stay warm in their sleeping bag when the temp is at least 30f. the situation will be written in inequality as  30F ≤ T. An inequality is used to express a comparison between two values.

In this case, the inequality states that the temperature, represented by the variable T, must be less than or equal to 30F in order for the person in the sleeping bag to stay warm. This means that if the temperature is 30F or higher, the person in the sleeping bag will stay warm.   Inequalities use a few different symbols to represent the comparison relationship between two values.

In this case, the symbol used is ≤, meaning "less than or equal to".

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.

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.

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.

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

This is an exponential function, so it will represent either growth or decay. To determine whether it is growth or decay and what rate it is, we need to look at the coefficient of the exponential term, which in this case is 1.262.
