we are given that , a ladder is placed against a side of building , which forms a right angled triangle . We wre given one side of a right angled triangle ( hypotenuse ) as 23 feet and the angle of elevation as 76 ° . We can find the Perpendicular distance from the top of the ladder go to the ground by using the trigonometric identity:

\( \qquad\quad\bull ~{\boxed{\bf{ Sin\theta =\dfrac{Perpendicular}{Hypotenuse}}} }~\bull\)

Here,

\( \quad\dashrightarrow\quad \sf { sin\theta =\dfrac{P}{H}}\)

\( \quad\dashrightarrow\quad \sf { sin76° =\dfrac{P}{23}}\)

\( \quad\dashrightarrow\quad \sf { 0.97=\dfrac{P}{23}}\)

\( \quad\dashrightarrow\quad \sf {P = 0.97 \times 23 }\)

\( \quad\dashrightarrow\quad \sf { P = 22.32}\)

‎ㅤ‎ㅤ‎ㅤ~Hence, the distance from the top of the ladder to the ground is 22.32 feet !

Answer:

y = 2/3 x + 5/3.

Step-by-step explanation:

Slope m = (3-1)/(2-(-1)) = 2/3.

y - y1 = m(x - x1)

y - 1 = 2/3(x - (-1))

y - 1 = 2/3(x + 1)

y - 1 = 2/3 x+ 2/3

y = 2/3 x + 5/3.

Answer:

So this is an inequality and can be easily solved if its opposite number is done with both the sides. There are some inequality rules which are:

1. when absolute values removed; the number in the oppostite side becomes negative and if negative then positive. And the signs are changed to its opposite sign. Like greater than to less than or vise versa.

2. When both the sides are divided or multiplied by a negative number the signs are changed.

I - 7b + 5 I ≤ 33

- 7b + 5 ≥ -33

- 7b + 5 - 5 ≥ - 33 - 5

- 7b ≥  - 38

Step-by-step explanation:

v = u + at

v-u = at

a = (v -u)/t

When t = 4, u=10, v=50

a = (50-10)/4

a= 40/4

a = 10

The dimensions of the fenced-in area is given as

either length is 35 yards and width is 80 yards ,  

or length is 40 yards and width is 70 yards .

In the question ,

given that the total length of the fence (perimeter) = 150 yards

let L be the length of the portion to be fenced

let B be the width of the house

Given that , one side of the portion is fenced using the back side of the house

So, the perimeter of the portion to be fenced is 2L+B

equating both the perimeter ,we get

2L+B=150

B=150-2L       ....(i)

Also , given that the area of the  fenced-in portion = 2800 yards

also the formula for area of fenced-in portion = L×B

hence

L*B=2800

Substituting the values of B from equation(i) , we get

L*(150-2L)=2800

150L - 2L² = 2800

2L² - 150L + 2800 = 0

simplifying further , we get

L² - 75L + 1400 = 0

L² -40L -35L +1400 = 0          .....using splitting the middle term

L(L-40) -35(L-40) = 0

(L-35)(L-40) = 0

So , L = 35 yards or L = 40 yards

Using L = 35 yards , we get B = 150-2(35) = 80 yards

and using L =40 yards , we get B = 150-2(40) = 70 yards .

Therefore , the dimensions of the fenced-in area is given as

either length is 35 yards and width is 80 yards ,  

or length is 40 yards and width is 70 yards .

Maria received 999 votes out of a total of 25, which means that 999/25 = 39.96% of the class voted for her. Therefore, approximately 40% of the class voted for Maria.

To find the percentage of the class that voted for Maria, we need to first find the total number of students who voted:

Total number of students who voted = number who voted for Benjamin + number who voted for Sahil + number who voted for Maria

= 444 + 1212 + 999

= 2655

Now we can calculate the percentage of the class that voted for Maria:

Percentage of class that voted for Maria = (number who voted for Maria / total number of students who voted) x 100%

= (999 / 2655) x 100%

= 37.6%

Therefore, 37.6% of the class voted for Maria, approximately 40% of the class voted for Maria.

The measure of the angle of the straight line is equal to the 180 degree. the measure of the \(\angle HLI\) is equal to the \(\angle ILM\) which is 30 degrees. Thus the option 4 is the correct option.

The measures of the angle KLH is 120 degrees.

The image is attached below for the given problem.

The measure of the angle of the straight line is equal to the 180 degree.

The line KLM is a straight line thus the angle of the line KLM is equal to the 180 degrees.

The value of the angle ILH is 30 degrees given in the figure.

The value of the angle KLH is given in the question which is equal to the 120 degrees. Thus,

\(\angle KLM=\angle ILM +\angle KLH + \angle ILH\)

Take the angle KLH and the angle ILH on the other side,

\(\angle ILM=\angle KLM -\angle KLH - \angle ILH\)

\(\angle ILM=180-120-30\)

\(\angle ILM=30\)

Thus the measure of the \(\angle ILM\) is 30 degrees.

As the measure of the \(\angle HLI\) is equal to the \(\angle ILM\) which is 30 degrees. Thus the option 4 is the correct option.

The closest probability is 0.1742.

To find the probability that fewer than 30% of the employees in the sample would respond that they spend more than 30 minutes commuting to work, we can use the binomial distribution.

Let's denote the probability of an employee responding that they spend more than 30 minutes commuting to work as p. In this case, p = 0.35.

We want to find the probability of having fewer than 30% of the employees respond in this way. So, we need to calculate the probability of having 0, 1, 2, ..., 23, 24, or 25 employees out of 80 respond in this way.

Using a binomial probability calculator or statistical software, we can sum up these individual probabilities to get the desired result. The closest answer provided is 0.1742.

To solve the following using BEDMAS 5X4 - (3 + 1)2 ÷ 2:BEDMAS is an acronym that represents the order of operations for arithmetic operations in the correct order, that is, "Brackets", "Exponents", "Division and Multiplication", and "Addition and Subtraction."The full form of BEDMAS is- B stands for Brackets.E stands for Exponents.D stands for Division.M stands for Multiplication.A stands for Addition.S stands for Subtraction.

The given expression is;5X4 - (3 + 1)2 ÷ 2When we solve this expression using the BEDMAS rule of the order of operations, we get;= 5 x 4 - (3 + 1) x 2 ÷ 2[Since brackets comes first, then multiplication and division, followed by addition and subtraction.]= 20 - 4 x 2 ÷ 2[Perform multiplication: 3 + 1 = 4 and 4 x 2 = 8]= 20 - 8[Perform Division: 8 ÷ 2 = 4]= 12Therefore, the value of the expression is 12.The solution of the given expression using the BEDMAS rule of the order of operations is explained. The BEDMAS rule defines the correct order in which arithmetic operations should be performed.

It consists of four fundamental operations. They are brackets, exponents, multiplication and division, and addition and subtraction. The expression, 5X4 - (3 + 1)2 ÷ 2, can be solved using the BEDMAS rule of operations. First, we will simplify the brackets, followed by division and multiplication, then addition and subtraction. We will get the following expression 5 x 4 - (3 + 1) x 2 ÷ 2. We will then perform multiplication by finding the product of (3 + 1) and 2, which equals 8. Finally, we will perform division by dividing 8 by 2, which equals 4. After we have completed these steps, we will subtract 8 from 20 to get the final answer of 12.
