*see attachment for the diagram of the wall

Answer:

6 cans

Step-by-step explanation:

First, let's calculate the area of the wall to be painted = area of a rectangle

Area of the rectangle = length*width

From the diagram,

Length = 13 ft

Width = 10 ft

Area = 13*10 = 130 ft²

Given that 1 can of paint covers 25 ft²,

Number of can of paints that will cover 130 ft² = 130/25 = 5.2

This means we will need more than 5 cans. So Joan will need to get roughly 6 cams of blackboard paint.

Complete question is;

Scores on a test are normally distributed with a mean of 200 and a standard deviation of 12. Find the probability that a randomly selected student scored less than 218.

Answer:

0.93

Step-by-step explanation:

We are given;

Mean; μ = 200

Standard deviation; σ = 12

Random value; x¯ = 218

Z-score formula is;

z = (x¯ - μ)/σ

z = (218 - 200)/12

z = 18/12

z = 1.5

From z-table, attached, probability = 0.93

Answer:

The equation is;

4(2.5x-3) = 3(2x-2)

The value of x is 1.5

Step-by-step explanation:

Mathematically, the perimeter of a square is simply the product of the length of the side and 4

Secondly, the perimeter of an equilateral lateral triangle is the product of the length of its side and 3

Thus, mathematically, we have it that;

4(2.5x-3) = 3(2x-2)

10x - 12 = 6x -6

10x -6x = -6 + 12

4x = 6

x = 6/4

x = 1.5

Answer:

B. 12x + 8

Step-by-step explanation:

2x + 5 + 4x - 1 + 2x + 5 + 4x - 1

Combine like terms.

6x + 5 - 1 + 2x + 5 + 4x + 1

8x + 5 - 1 + 5 + 4x - 1

12x + 5 - 1 + 5 - 1

12x + 10 - 1 - 1

12x + 10 - 2

Subtract 2 from 10 to get 8.

12x + 8

The perimeter of the rectangle is 12x + 8, which is B.

Answer:

A

Step-by-step explanation:

143.6° and x are adjacent angles and sum to 180° , then

x + 143.6° = 180° ( subtract 143.6° from both sides )

x = 36.4° → A

Answer: −(3x−2)(x+6)

Step-by-step explanation:

We know it's factored because...

−(3x−2)(x+6)

If we multiply, then we get what we started with.

-3x * x = -3x^2

2 * x = 2x

-3x * 6 = -18x

2 * 6 = 12

-3x^2 - 18x + 2x + 12

-3x^2 - 16x + 12

Answer:

I can not do this.

Step-by-step explanation:

oh, doing 12 year old math.

Step-by-step explanation:

Mean= Sumof all the numbers/ number of data

So,

23+37+11+58+13+45=187

Now...

187/6=31.166666667 Answer

hope it helps....

What is the mean of this data: 23, 37, 11, 58, 13, 45.

To find the mean of this data, first of all we should add up all the given numbers and then divide by how many numbers there are.

So, [tex] \bf Mean \: = \frac{23 \: + \: 37 \: + \: 11 \: + \: 58 \: + \: 13 \: + \: 45}{6} [/tex]

[tex] \bf Mean \: = \frac{187}{6} [/tex]

[tex] \bf Mean \: = \: 31.17 [/tex]

Answer: i think its alternate interior

Answer:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of  a quadratic equation is given as ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.Hence given x^2-5x-19=0, to complete the square, we add (-5/2)^2 to both sides following the illustration given.This is 25/4 or 6.24

Answer:

B.

Step-by-step explanation:

So, lets remember a few things first.

#1: The formula for finding the answer is A^2+B^2=C^2

#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.

Now lets plug in what we already know, and see if we canf igure out the annswer:

A^2+12^2=13^2

Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.

If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:

Ok, not  too bad, the A is the unkown value, which is the opposite side.

Now, how do we figure this out? Well, we just need to sovle for A.

To do this, lets clean up our equation by first sqauring all the values(except for the unkown):

A^2+144=169

Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.

This will now look like:

A^2=25(169-144=25)

Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.

([tex]\sqrt{A^2}=A[/tex])=([tex]\sqrt{25}=5[/tex])

A=5

This is your answer.
