Aisha wants to paint the wall of the room. She knows that each can of the paint contain one gallon. A half gallon will completetly cover a 55 square feet of wall. Each of the four wall of the room is 10 feet high. Two of the walls are 10 feet wide and two of the walls are 15 ft wide. How many one gallons buckets of paint does aisha need to buyin order to paint the room ?
Answer:
It doesn't say what to do with that 0.1 of a gallon. I would buy another gallon or dilute what I had so it came to exactly 9.1 gallons. In math, I suppose the answer is 9.
In reality it would be 10.
You have to choose. What has been done with other questions like this.
Step-by-step explanation:
1 can covers 55 square feet.
h = 10
w1 = 10 feet
w2 = 10 feet
w3 = 15 feet
w4 = 15 feet
Total area = Area of wall 1 + wall 2 + wall 3 + wall 4
Total area = 10*10 + 10*10 + 10*15 + 10* 15
Total area = 100 + 100 + 150 + 150
Total area = 500 feet^2
1 gallon / 55 ft^2 = x / 500 ft^2 Cross multiply
55 * x = 500 Divide by 55
x = 500/55
x = 9.1 gallons.
In real life you would buy another gallon.

A landscaper buried a water line around a rectangular lawn to serve as a supply line for a sprinkler system. The length of the lawn is 6 times its width. If 630 feet of pipe was used to do the job, what is the length and the width of the lawn
Answers:
Length = 270 feet
Width = 45 feet
========================================================
Work Shown:
x = width
6x = length, since it is 6 times the width
P = perimeter of rectangle
P = 2*(Length + Width)
P = 2*(6x + x)
P = 2*(7x)
P = 14x
Plug in the given perimeter P = 630 and solve for x.
P = 14x
14x = P
14x = 630
x = 630/14
x = 45
The width is 45 feet.
The length must be 6x = 6*45 = 270 feet.
The required length and width of the lawn is given as Length = 270 feet and Width = 45 feet.
Given that,
A landscaper buried a water line around a rectangular lawn to serve as a supply line for a sprinkler system. The length of the lawn is 6 times its width. If 630 feet of pipe was used to do the job, what is the length and the width of the lawn is to be determined.
Perimeter is the measure of the figure on its circumference.
Here,
let the length be l and the width be w,
According to the question,
l = 6w
and
Perimeter of the lawn = 630
2 [l + w] = 630
2 [6w + w] = 630
14w = 630
w = 45
Now,
l = 45[6] = 270
Thus, the required length and width of the lawn is given as Length = 270 feet and Width = 45 feet.

Lesson 1 Practice Problems
Taking into account the original image that appears in the attached document and verifying the correct solution in each case:
1. The figures that are scaled copies of the original are:
Figure 2Figure 42. I'm not agree with Tyler's affirmation.
SCALING FIGURES.
When you must scale figures, you must remind the scale must be applied in all dimensions of the figure, when a figure is in two dimensions, I mean, the figure has height and length, the scale must be applied to this two dimensions, and the figure must the same form of the original to be a scaled copy.
In the first exercise, the original A is a figure with two squares of height and two squares of length 2x2, by this reason, each scaled copy must be the same height as length (1x1, 3x3, 4x4, 5x5, 6x6 and others).
As you can see, the figure 2 has 4 units of height and 4 units of length 4x4, it's a scaled copy, the figure 4 has 1 unit of height and 1 units of length 1x1, it's a scaled copy, but the figure 1 has 3 units of height and 2 units of length 3x2, it's not a scaled copy, and the figure 3 hasn't the same form of the original A, by this, it's not a scaled copy.
In the second exercise, you can´t agree with Tyler because the figure B is the half of the figure A, but just in the height, remember this must be the same in the length to obtain a correct scaled copy, you can see in the exercise, the figure B has the same length as the figure A, by this reason, the affirmation of Tyler is wrong, for that to be true, the height and the length should be half in the figure B.

Answer:
"complete the square" to put in vertex form
Step-by-step explanation:
It may be helpful to consider the square of a binomial:
(x +a)² = x² +2ax +a²
The expression x² +x +1 is in the standard form of the expression on the right above. Comparing the coefficients of x, we see ...
2a = 1
a = 1/2
That means we can write ...
(x +1/2)² = x² +x +1/4
But we need x² +x +1, so we need to add 3/4 to the binomial square in order to make the expressions equal:
[tex]x^2+x+1\\\\=(x^2+x+\frac{1}{4})+\frac{3}{4}\\\\=(x+\frac{1}{2})^2+\frac{3}{4}[/tex]
_____
Another way to consider this is ...
x² +bx +c
= x² +2(b/2)x +(b/2)² +c -(b/2)² . . . . . . rewrite bx, add and subtract (b/2)²*
= (x +b/2)² +(c -(b/2)²)
for b=1, c=1, this becomes ...
x² +x +1 = (x +1/2)² +(1 -(1/2)²)
= (x +1/2)² +3/4
_____
* This process, "rewrite bx, add and subtract (b/2)²," is called "completing the square"—especially when written as (x-h)² +k, a parabola with vertex (h, k).
0.4141 rounded to the nearest thousandth
Answer:
0.4141 rounded to the nearest thousandth is 0.414.
Step-by-step explanation:
Since the number is 0.4141, and the number following the thousandths place is under 5, the thousandth place stays the same. If it were 5 or over, it would round up making it 0.415, but it's not so it is 0.414.

For our equation, we need to find out what our two smaller equations are.
We can see that angle HGF is our largest angle, and it is composed of EGF, and HGE. We can insert our values into an equation to solve:
16x+4=110+3x+11
We can then combine like terms:
16x+4=121+3x
To solve for x, we need to put it by itself on one side of the equation. So, let's subtract 4 from both sides:
16x=117+3x
Now, let's subtract 3x from both sides:
13x=117
Now, let's divide both sides by 13 to solve for x:
x=9
Now, we know that x=9.

Find the distance between the ponits.
(-3, -6) and (3, x6)
Help please
Step-by-step explanation:
Hey there!
The given points are: (-3,-6) and (3,-6).
x 1 = -3 y1 = -6
x 2 = 3 y2 = -6
Use distance formula;
[tex]d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
Keep all the values;
[tex]d = \sqrt{( {3 - ( - 3))}^{2} + ( { - 6 - ( - 6))}^{2} } [/tex]
Simplify:
[tex]d = \sqrt{ {(6)}^{2} + {( - 6 + 6)}^{2} } [/tex]
[tex]d = \sqrt{ {(6)}^{2} } [/tex]
Therefore, the distance is 6 units.

Answer:
see explanation
Step-by-step explanation:

(25x + 8) and (9x + 2) are adjacent angles and sum to 180° , then
25x + 8 + 9x + 2 = 180 , that is
34x + 10 = 180 ( subtract 10 from both sides )
34x = 170 ( divide both sides by 34 )
x = 5
Then
9x + 2 = 9(5) + 2 = 45 + 2 = 47
(7y + 5) and (9x + 2) are vertical angles and are congruent , so
7y + 5 = 47 ( subtract 5 from both sides )
7y = 42 ( divide both sides by 7 )
y = 6
------------------------------------------------------
(8)
(11x - 24) and (7x + 30) are vertical angles and are congruent, so
11x - 24 = 7x + 30 ( subtract 7x from both sides )
4x - 24 = 30 ( add 24 to both sides )
4x = 54 ( divide both sides by 4 )
x = 13.5
Similarly
(17y - 4) and (5y + 38) are vertical angles and congruent , then
17y - 4 = 5y + 38 ( subtract 5y from both sides )
12y - 4 = 38 ( add 4 to both sides )
12y = 42 ( divide both sides by 12 )
y = 3.5
What is the equation of a line with a y-intercept at (0, 6) and a slope of 3? y = 3x + 6 y = 6x + 3 y = 3x − 6 y = −6x − 3
Answer:
[tex]y=3x+6[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
We're given that the slope of the line is 3. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=3x+b[/tex]
We're also given the point (0,6). Since the y-intercept occurs when x=0, the y-intercept is therefore 6. Plug this into [tex]y=3x+b[/tex] as b:
[tex]y=3x+6[/tex]
