Answer:
Step-by-step explanation:
T.S.A=2(LXW) + 2(LXH) + 2(WXH)
=2(8mx5m) + 2(8mx2m) + 2(5mx2m)
=(2x40m²) + (2x16m²) + (2x10m²)
=80m² + 32m² + 20m²
=132m²
Aisha wants to paint the four walls of her living room.
Each wall is 2.4 m high and 3.7 m long.
One wall has a door of 2 m by 0.7 m.
Tins of paint cost £12 per 1.5 L tin.
Each litre of paint can cover 8 m2 of wall.
There is an offer of: Buy 2 tins get the 3rd at half price.
How much will Aisha pay to paint her living room?
9514 1404 393
Answer:
£30
Step-by-step explanation:
The total area of the four walls is ...
A = 4 × LW
A = 4 × (2.4 m)(3.7 m) = 35.52 m²
Subtracting the area of the door, we find the painted area to be ...
35.52 m² -(2 m)(0.7 m) = 34.12 m²
Painting this area will require ...
(34.12 m²)/(8 m²/L × 1.5 L/tin) = 2.8433... tins
Aisha will need to buy 3 tins of paint, for which she pays 2.5 times the price of 1 tin:
2.5 × £12 = £30 . . . . Aisha's cost to paint her living room
£25 or £20.10
Step-by-step explanation:
calculate the area to be painted:
2.1x4.5= 9.45m^2 for each wall
x4= 37.8m^2
area of door= 1.8x0.9= 1.62m^2
subtract the area of the door from the wall area
37.8-1.62= 36.18m^2 to be painted
divide the area by the area that 1L of paint can cover
16.18/12= 3.015 L needed
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.
£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25
or
calculate price for 0.015L
1.5=£10
divide both sides by 100
0.015= £ 0.10
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L
£20+£0.10= £20.10
I DONT KNOW IF THIS IS RIGHT but hope it helps :)

225/40 which can simplify to 5 and 5/8
Step-by-step explanation: 3 and 1/8 turns into 25/8, 1 and 4/5 turns into 9/5. Multiply numerator by numerator then denominator by denominator to get 225/40, which simplifies out to 5 and 5/8.
>) Find the slope of the line that passes through (1, 11) and (9, 2). )) Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
The slope is [tex] - \frac{9}{8} [/tex].
Step-by-step explanation:
[tex]m = slope[/tex]
Remember: [tex]m = \frac{y_2 - y_1 }{x_2 - x_1} [/tex]
☆All you have to do is plug in.
[tex]m = \frac{2 - 11}{9 - 1} = \frac{ - 9}{ \: \: 8} = - \frac{9}{8} [/tex]

Help!! Find the indicated angle measure. Show your work.
Answer:
m∠NPM = 101
Step-by-step explanation:
Since LM is a straight line, Angle LPM and Angle NPM have to equal 180 degrees (they are supplementary), so we make the equation:
180-79=measure of angle NPM
m∠NPM = 101
Answer:
<NPM = 101°
Step-by-step explanation:
<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)
<NPM = 180° - 79°
<NPM = 101°

What are the coordinates of point H?
9514 1404 393
Answer:
(-1 1/2, 3)
Step-by-step explanation:
Coordinates are written as an ordered pair. That means the position of the coordinate value in the pair has significance.
By convention, the first coordinate is the "x" coordinate. It is the number of units the point lies to the right of the x=0 point on the horizontal scale. Here, the point lies between 1 and 2 units left of 0, corresponding to an x-coordinate of -1 1/2. So far, we know the point coordinates are (-1 1/2, <something>).
At this point, you can check to see if this narrows down the answer choices. It does. The only available answer choice with a first coordinate of -1 1/2 is the correct one: (-1 1/2, 3).
__
The second coordinate in the ordered pair is the "y" coordinate. It is the number of units the point lies above the point y=0 on the vertical scale. Here, the point lies 3 units above the point y=0, corresponding to a y-coordinate of 3. Now, we know the coordinates of the point are (x, y) = (-1 1/2, 3).
_____
Additional comment
Ordered pairs of coordinates are not always x- and y- coordinates. Sometimes, they are elevation and azimuth, latitude and longitude, radius and angle. However, for the vast majority of work in Algebra, an ordered pair of coordinates refers to (x, y) coordinates on a Cartesian plane (one with grid lines running horizontally and vertically).

Last year there were m members in a photography club. This year the number of
members has increased by 10%. The expression m + 0.1m represents the number of
members in the club this year. What is this expression written in simplest form?
Answer:
m + 10/100(m)
Step-by-step explanation:
Last year there were m members in a photography club.This year the number of members has increased by 10%m + 0.1m represents the number of members in the club this year.So m represents the number of members in the club last year.
A 10% increase of the members = [tex]\frac{10}{100} * m[/tex] = 0.1m
Hence the number of members in the club this year = m + 0.1m

Answer:
x = 5
Step-by-step explanation:
Since the problem shows us that all the angles of the triangle are equal, we can confirm this is an equilateral triangle. Equilateral triangles have the same angles and the same side lengths. Knowing this, we can set up an equation to solve for x.
6x - 5 = 5x (Given)
-5 = -x (Subtract 6x on both sides)
5 = x (Divide -1 on both sides)
Therefore, x = 5.
Answer:
x = 5
Step-by-step explanation:
Since all the three angles of the triangle GJH are marked by identical signs, thus they are congruent.
Therefore, triangle GJH is an equilateral triangle.
Measures of all sides of an equilateral triangle are equal.
So,
6x - 5 = 5x
6x - 5x = 5
x = 5

Answer:. sum of interior angles:
Heptagon: 900°
14gon 2160°
Step-by-step explanation: Divide 360 by the number of sides to get the measure of the average or regular central angle (same as an exterior angle)
360/7 = 51.43 360/14 = 25.7.
Subtract from 180 to find the interior angle.
180 - 51.43 = 128.57
180 - 25.7 = 154.3
Multiply the measure of the interior angle by the number of sides to find the sum of the interior angles.
128.57× 7 = 900
154.3 × 14 = 2160

Answer:
y = (1/4)x^2 -x -4
Step-by-step explanation:
When you are given a focus and a vertex, the equation of a parabola can be written as ...
y = (1/(4p))(x -h)² +k . . . . . . vertex (h, k); focus-vertex distance p
Here, the vertex is (h, k) = (2, -5) and the focus-vertex distance is 1. That means the equation of the parabola in vertex form* is ...
y = (1/4)(x -2)² -5
Expanding this equation, we get ...
y = (1/4)(x² -4x +4) -5 = (1/4)x² -x +1 -5
Then the standard form equation is ...
y = (1/4)x² -x -4

* In the UK, and perhaps other places, the vertex form is referred to as "standard form." You need to be aware of the form that is being requested here. I have answered using the US version of "standard form." YMMV
