9514 1404 393
Answer:
£27.50
Step-by-step explanation:
The general approach is ...
find the area to be paintedfigure the amount of paint requireddetermine the discounted cost of the paint1. The area to be painted will be the area of the four walls, less the area of the door (which is assumed to be a hole in the wall, so is not painted).
Each wall has the same dimensions, so the same area. The area of the rectangular wall is ...
A = LW
A = (3.5 m)(2.6 m) = 9.1 m²
The area of the door is ...
A = (2.2 m)(0.8 m) = 1.76 m²
Then the area to be painted is the area of the 4 walls less the area of the door:
painted area = 4(9.1 m²) -1.76 m² = 34.64 m²
__
2. Each 2 L tin of paint will cover (2 L)×(8 m²/L) = 16 m², so the number of tins needed is ...
(34.64 m²)/(16 m²/tin) = 2.165 tins
We assume this means Aisha will need to purchase 3 tins, since she will need more paint than is provided by 2 tins.
__
3. Because of the price offer on the paint, Aisha will pay full price for the first two tins, half price for the 3rd tin. That is, she will pay 2 1/2 times the full price of a tin when she buys the 3 tins of paint she needs. Each tin costs £11, so Aisha will pay ...
(2 1/2)(£11) = £27.50
Aisha will pay £27.50 for the paint to paint her living room.

Suppose that Theta is an angle in standard position whose terminal side intersects with the unit circle at (21/29,20/29). Fine the exact values of cscTheta, cosTheta, and cotTheta
Answer:
The coordinates of the vertex is:
x = 21/29, y = 20/29Horizontal leg = x, vertical leg = 20/29, hypotenuse = 1 (radius of unit circle)
csc θ = hypotenuse / opposite = 1 / (20/29) = 29/20 cos θ = adjacent / hypotenuse = (21/29) / 1 = 21/29cot θ = adjacent / opposite = (21/29) / (20/29) = 21/20A flagpole is 24 ft tall. A steel wire that is

Trigonometry!!
==========================================================
Explanation:
We are told that quadrilateral ABCD is similar to quadrilateral EFGH.
The order of the four letter sequence is important.
For ABCD, we have AB as the first pair of letters. For EFGH, we have EF as the first pair of letters.Therefore, AB and EF are corresponding sides.
So AB = 10 and EF = x pair up together. We can form the ratio AB/EF which becomes 10/x.
The diagram shows that AD = 8. Notice that A and D are the first and last letters of ABCD. The first and last letters of EFGH are E and H. We can see that AD and EH correspond to one another because of this.
AD = 8 and EH = 6 forming the ratio AD/EH = 8/6
Because the quadrilaterals are similar, the corresponding ratios must be the same. Therefore, AB/EF is the same as AD/EH.
-----------------------
Let's set up a proportion to solve for x
AB/EF = AD/EH
10/x = 8/6
10*6 = x*8
60 = 8x
8x = 60
x = 60/8
x = 7.5 Answer is choice D
Solve the following quadratic equation for all values of xx in simplest form.
5(2x+1)^2+6=26 cant figure this out!!
Answer:
x=1/2 and x=-3/2
Step-by-step explanation:
5(2x+1)^2+6=26
5(2x+1)^2=20
(2x+1)^2=4
2x+1=±2
Now make two equations and solve both for x:
2x+1=2
2x=1
x1=1/2
2x+1=-2
2x=-3
x2=-3/2
What is 2 over 5 x 5 over 8
Answer:
the answer is 1/4
Step-by-step explanation:
2/5 × 5/8
2× 5/ 5 × 8
= 10/40
=1/4
Answer:
1/4
Step-by-step explanation:
You would do 2/5 times 5/8 which would equal 10/40 cause 5 times 2 is 10 and then 5 times 8 is 40 and then you would simplify the fraction 10/40 which would make it 1/4

If 2/3 is multiplied by a fraction greater than 1, which of these could be the product?
Answer:
Any number bigger than 2/3
Step-by-step explanation:
btw, I didn't see the options but here's the explanation
When you multiply by a part of a whole, a fraction, you are getting smaller. When you multiply by a number bigger than one, your product gets bigger. So, any number bigger than 2/3 works just fine

I don’t understand radicals :/ pls help :)
Answer:
B.
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

Split this figure out. Find the area of the square, as well as the rectangle.
First, the square
A= 4 x 3
A= 12 ft^2
Therefore, the square has an area of 12ft^2.
Then, the rectangle.
We must first find the length of the unknown side.
We have two measurements of 3ft on each side, as well as the middle measurement of 4ft.
So,
3+3+4=10
Now, find the area.
A= 2 x 10
A=20ft^2
Add the areas.
20+12=32ft^2
Therefore, the area of the figure is 32ft^2.
I hope this is correct. Best of luck.

What do A and B equal?
PLEASE ANSWER I WILL GIVE A BRAINLIEST
Answer:
a=2
b=2
Step-by-step explanation:
This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Si se lanzan 2 dados ¿ cuantas posibilidades hay de que las caras hacia arriba sumen un numero menor que 7?
Answer:
P = 15/36 = 0.4166...
Step-by-step explanation:
Cada dado tiene 6 caras, con los números entre 1 y 6.
Entonces tenemos dos eventos, con 6 posibles resultados cada uno.
El número total de resultados para el evento de lanzar los dos dados, es el producto de los números de resultados para cada dado, entonces tenemos:
C = 6*6 = 36 posibles resultados.
Ahora tenemos que contar el número de resultados en donde la suma es menor a 7.
Usando la notación:
(resultado del dado 1) y (resultado del dado 2) = suma
Esos son:
1 y 1 = 2
1 y 2 = 3
1 y 3 = 4
1 y 4 = 5
1 y 5 = 6
2 y 1 = 3
2 y 2 = 4
2 y 3 = 5
2 y 4 = 6
3 y 1 = 4
3 y 2 = 5
3 y 3 = 6
4 y 1 = 5
4 y 2 = 6
5 y 1 = 6
Hay 15 resultados donde la suma de los resultados individuales es menor a 7.
Entonces de un total de 36 posibles resultados, 15 cumplen lo que queremos, asi que la probabilidad de que las caras hacía arriba sumen un número menor que 7 son de 15 entre 36, o:
P = 15/36 = 0.4166...
