Answer:
The number of tiles needed is 1.105.[tex]\overline 3[/tex] tiles
Step-by-step explanation:
The given data on the dimensions of the bathroom wall are;
The length, l = 2.5 m
The width, w = 2.05 m
The height, h = 3 m
The dimension of the tiles with which the walls are to be covered = 15 cm by 15 cm
The dimensions of the tiles in meters = 0.15 m by 0.15 m
The number of tiles savings made on the doors and windows of the bathroom = 108 tiles
Let 'A' represent the surface area of the bathroom wall, we have;
A = h·w + h·w + l·h + l·h = 2·h·w + 2·l·h = 2·h·(w + l)
∴ A = 2 × 3 m (2.5 m + 2.05 m) = 27.3 m²
The surface area per tile, Tₐ = 0.15 × 0.15 = 0.0225
∴ Tₐ = 0.0225 m²/tile
The number of tiles needed, n = A/Tₐ - 108 tiles
∴ n = 27.3 m²/(0.0225 m²/tile - 108 tiles = [tex]\left (1105+\dfrac{1}{3} \right )[/tex] tiles = 1.105.[tex]\overline 3[/tex] tiles
The number of tiles needed, n = 1.105.[tex]\overline 3[/tex] tiles.

Good Luck!
Step-by-step explanation:
You would add 16 to both side in the attempt of completing the square
Step 1: Move any constant number (this case, it's 35) to the other side
Step 2: You will have a format of ax2 + bx = c, where your a = 1, b = 8, and c = 35
*a must always be 1*
Step 3: Divide b by 2 and then square that number. Your b = 8, so 8/2 is 4. Squaring 4 gives you 16.
Hence, that's why you add 16 to both side from your question.
The circumference of a circular painting is 43.96 feet. What is the diameter of the painting? Use 3.14 for π and do not round your answer.
Answer:
14 feet
Step-by-step explanation:
c = πd
Plug in the givens
43.96 = 3.14d
Divide both sides by 3.14
14 = d
Answer:
Diameter = circumference ÷π
43. 96÷3. 14 =14 feet

the answer is
y≥2x/5+2
Step-by-step explanation:
we moved the y to the right site and the -10 to the left site
so we had
2x+10≤5y
and then we devided by 5
2x/5+10/5≤y
y≥2x/5+2
hopefully its correct
Answer: Choice D
[tex]y \ge \frac{2}{5}x +2\\\\[/tex]
=======================================
Work Shown:
[tex]2x - 5y \le -10\\\\-5y \le -2x-10\\\\y \ge \frac{-2x-10}{-5} \ \text{ ... see note1 below}\\\\y \ge \frac{-2x}{-5} - \frac{10}{-5}\\\\y \ge \frac{2}{5}x +2 \ \text{ ... answer is choice D}\\\\[/tex]
Note1: when dividing both sides by a negative number, the inequality sign flips.
----------------
Here's another approach that doesn't involve dividing both sides by a negative number.
[tex]2x - 5y \le -10\\\\2x \le -10+5y\\\\2x +10\le 5y\\\\5y \ge 2x+10 \ \text{ .... see note2 below}\\\\y \ge \frac{2x+10}{5}\\\\y \ge \frac{2x}{5} + \frac{10}{5}\\\\y \ge \frac{2}{5}x +2\\\\[/tex]
Note2: I swapped the left and right sides. Doing this swap means that the inequality sign must flip as well.
Y=-2x-3,y=-2x+2 how many solutions does the system have
Answer:
3x + 3 = -2x + 3
3x + 2x = 3 - 3
5x = 0
x =0.
So y = 3(0) + 3 = 3.

Solutions to a quadratic equation are -7 and 1. What is the equation of its axis of symmetry?
Answer:
Axis of symmetry: x=-4
Step-by-step explanation:
If x=-7 and x=-1 are solutions to a quadratic equation, then that quadratic equation must be (x+1)(x+7)=0 -> x^2+8x+7=0 as both solutions satisfy the Zero Product Property where the function is f(x)=x^2+8x+7. The axis of symmetry would be the line x=-b/2a which means the axis of symmetry is x=-(8)/2(1)=-8/2=-4 -> x=-4. It can also be found by turning f(x)=x^2+8x+7 into f(x)=(x+4)^2-9 by completing the square, and since h=-4, then the axis of symmetry would be x=h=-4. Refer to the graph.

Find measure FGH
A) 238
B) 119
C) 196
Answer:
238
Step-by-step explanation:
Important note: ∠FAH is an inscribed angle and arc mFGH is it's intercepted arc
opposite angles in a quadrilateral formed inside of a circle area supplementary
Supplementary meaning that they add up to equal 180
So 13x + 15 + 8x - 3 = 180
We now solve for x
step 1 combine like terms
13x + 8x = 21x
15 - 3 = 12
12 + 21x = 180
step 2 subtract 12 from each side
12 - 12 cancels out
180 - 12 = 168
21x = 168
step 3 divide each side by 21
21x / 21 = x
168 / 21 = 8
we're left with x = 8
Now we substitute 8 for x in 13x + 15
13 ( 8 ) + 15
13 * 8 = 104
104 + 15 = 119
So ∠FAH = 119
Recall that an included angle is equal to half the measure of its intercepted arc.
so arc mFGH = 2 (119)
2 * 119 = 238
Therefore your answer is A
Hi! Does anyone know the answer to this question? I’m bad at geometry and I’m struggling to get the answer. Please help!
The diagram is shown below
Point A is located at (0,8). It's exactly 8 units away from the origin (0,0).
Let's say point C is at the origin. That would mean segment AC is 8 units long.
Divide segment AC into four equal parts. Each part is 8/4 = 2 units long.
Move to point A(0,8) and then drop down 2 units to arrive at (0,6). Use your straightedge to draw a horizontal line from (0,6) until you reach the diagonal line AB. Mark point P on the diagonal line. Refer to the diagram to see what I mean.
Now move back to (0,6) and drop down another 2 units to get to (0,4). Draw a horizontal line through this point until you reach the diagonal line. Mark point Q on the diagonal line.
Repeat this process until you get to the origin. You'll find that segment AB has been cut into four equal parts. This works because we've divided AC into four equal parts, which helps divide AB into four equal parts. The two concepts are directly connected. More specifically, we're using similar triangles to help do the subdivisions here.
So this trick is very handy if you have a diagonal road you're trying to divide into four (or any number) equal parts. It's also useful if you are dealing with fencing and you want to divide which if your friends will take care of which portions of the fence. Those are just two examples of real world applications.

What is a box plot ?A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.
The term "box plot" comes from the fact that the graph looks like a rectangle with lines extending from the top and bottom.
The minimum is the lowest number in the data set.
18
The median is the middle number.
27
The first quartile (Q1) is the median of the lower half of data which lies at 25% of the data.
The third quartile (Q3) is the median of the upper half of data which lies at 75% of the data.
The maximum is the highest number in the data set; it is 38

Explain the benefits of data analysis in weather systems.
Huge volumes of data on the present state of environmental conditions, notably temperatures, moisture, and wind, are gathered in order to predict weather forecasts, and via the atmospheric procedure, meteorology data analysts assess how the atmosphere will change.

First you find the square root of 72 but it has none so instead you find the what multiplies to 72 but is still a perfect square. That is 9 times 8. The square root of nine is 3 so we leave that outside of the radical, and leave the 8 in there. Then we go to x. Exponents follow a different rule and you cannot get the square root of them so find if it's divisible by 2 by taking away 1 from nine making it x^8 and x. Then divide the 8 by 2 and you get x^4, leave the remaining single x in the radical. Bring that behind the 3 on the outside and do the same with the y. Now the y can be divided by 2 so that will be 8. Now there should b 3x^4y^8(radical sign)8x

A trapezoid has an area of 140 square centimeters with bases of 12 and 10 centimeters. What is the length of the height? Round to the nearest tenth place.
Answer:
12.7 cm
Step-by-step explanation:
Area of a trapezium = 1/2 x ( a + b) x height
a and b represents the bases
140 = 1/2 x (12 + 10) x h
140 = 11h
h = 140 / 11
h = 12.727 cm
h = 12.7 cm to the nearest tenth
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
