HOW DO u do this?? Plz help!!!! Question 2

Answer: 14.6 feet

Step-by-step explanation:

Since, here a ladder which has the length 15 foot  and it is far from the base of the wall by 3.5 feet.

Here L represents the length of the ladder while d  represents the distance of the ladder from the base of the wall. ( shown in figure)

While h represents height that the ladder reaches up the wall.

Thus, L= 15 foot, d= 3.5 foot

Then on applying Pythagoras theorem,

[tex]L^2=d^2+h^2[/tex]

⇒[tex]15^2=3.5^2+h^2[/tex]

⇒[tex]225=12.25+h^2[/tex]

⇒[tex]h^2=21.75[/tex]

⇒[tex]h=14.5859521458[/tex]≈ 14.6 foot

Thus,height that the ladder reaches up the wall= 14.6 foot ( approx)

Renewable electricity

Step-by-step explanation:

Renewable electricity is an option for everybody. Using a small solar panel device can create renewable electricity for your home. Renewable electricity is safer and cleaner.

The renewable source of energy is the generation of energy from naturally extracted resources. These sources are naturally replenishing due to excess consumption and overpopulation.

These renewable sources are virtually inexhaustible. The types of renewable energy sources are: biodiesel, wind, solar, hydropower, and many more.

Renewable electricity is the source of energy upon which the United States must focus its research and development efforts.

Renewable electricity is the most suitable option over which the research and development must focus for making it one of the main sources of energy for the country by the yer 2050.

This can be done by using solar panel devices at homes and factories so that they can generate their own electricity. This will help in saving the electricity supply from the poles.

The square root of 62 lies between the consecutive whole numbers 7 and 8, because 7² is 49 and 8² is 64, and 62 is between these two square numbers.

The student is asking for two consecutive whole numbers between which the square root of 62 lies. First, identify the whole numbers whose square roots are immediately less than and greater than √62. Considering square numbers we know, 7² = 49 and 8² = 64. Since 49 < 62 < 64, the square root of 62 must be between 7 and 8. Therefore, the two consecutive whole numbers are 7 and 8, as √62 is greater than 7 but less than 8.

The value of letter A on the box plot is given by A = 10

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.

here, we have,

we know that,

A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.

Given data ,

Let the box plot be represented as Z

Now , the values of the data from the box plot is given by

Z = { 10 , 12 , 15 , 21 , 24 , 30 }

The value of the letter A from the box plot is the first value

where A = 10

Therefore , the value of A is 10

Hence , the box plot is solved

Kerrie covered a table having 8 rows of square tiles.

Each row has 7 tiles. The table will be rectangular in shape.

The number of rows will be the length of the table and the number of tiles in each row will be the width of the table.

Area of rectangle = length x width.

Area of the table = 8x7= 56 square units.

The equation provided is a quadratic equation in standard form, which can be solved using methods such as factoring, completing the square, or the quadratic formula to find its roots.

The equation y=x^2-16x+63 is a quadratic equation, which is a polynomial equation of the second degree. The standard form of a quadratic equation is ax^2 + bx + c = 0. To solve this equation for x, you can either factor it, complete the square, or use the quadratic formula. If this specific equation was meant to be solved, we would look for values of x that make the equation true. This involves finding the roots of the equation, which are the x-intercepts of the parabola represented by the equation on a graph.

Answer:

60 feet

Step-by-step explanation:

Multiply the area by 2 to get 1200 feet. then, divide by 20 to get 60. The base of the a-frame is 60 feet.

(0 = 0) is a true statement, it means that the system of equations has infinitely many solutions.

The correct option is (C).

To solve the system of equations using elimination, we'll manipulate one or both equations to eliminate one of the variables, either \(x\) or \(y\). Let's start by using elimination to eliminate \(x\).

Given the system of equations:

[tex]\[ \begin{cases} 3x + 4y = 5 \quad \quad \quad \quad \quad (1) \\21x + 28y = 35 \quad \quad \quad (2)\end{cases} \][/tex]

We can see that if we multiply equation (1) by 7, we can eliminate (x) when we add the equations together:

[tex]\[ 7(3x + 4y) = 7 \times 5 \][/tex]

[tex]\[ 21x + 28y = 35 \][/tex]

Now, we can rewrite equation (1) as:

[tex]\[ 21x + 28y = 35 \quad \quad \quad \quad \quad (3) \][/tex]

Now, we'll subtract equation (2) from equation (3):

[tex]\[ (21x + 28y) - (21x + 28y) = 35 - 35 \][/tex]

[ 0 = 0 ]

Since (0 = 0) is a true statement, it means that the system of equations has infinitely many solutions.

So, the correct answer is option C: Infinitely Many Solutions.

Use elimination to solve the system of equations given by 3x + 4y = 5 and 21x + 28y = 35.

Answer:

Where is the pic?

Answer:

AC = 12 units.

Step-by-step explanation:

Given  : A triangle ABC with BD is the perpendicular bisector of AC.

To find :  What is the length of AC.

Solution : We have given triangle ABC with BD is the perpendicular bisector of AC.

Bisector : Which cut the line equally in to two part.

So , BD cut AC in  two  equal part AD = DC.

We can write

AC = AD + DC.

Plug the values DC = 6 , AD =DC = 6.

AC = 6 + 6

AC = 12 units.

Therefore , AC = 12 units.

the answer is c

The fully simplified form of √(1/169) is 1/13.

Given that an expression √(1/169), we need to simplify it,

To simplify the square root of 1/169, we can break it down as follows:

√(1/169)

Since 1 is the square of itself (1² = 1), we can rewrite the expression as:

√(1/169) = √(1)/√(169)

The square root of 1 is simply 1:

√(1/169) = 1/√(169)

Now, the square root of 169 is 13:

√(1/169) = 1/13

Therefore, the fully simplified form of √(1/169) is 1/13.
