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 :)

1/5 - 1/6
Plz ans. Fasttt
Answer: 1/30
5 and 6 both have a common factor of 30
30 will be our ned denominator
1/5 needs to be multipliued by 6
(since 5 times 6 is 30)
and
1/6 needs top be multiplied by 5
(since 6 times 5 is 30)
then you get 6/30 - 5/30 and that is just 1/30

Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Krystal spent $114 on 1 daylily and 12 pots of ivy. Danielle spent $150 on 10 daylilies and 10 pots of ivy. Find the cost of each item.
Answer:
$9 and $6Step-by-step explanation:
Let the cost of daylilies = d and ivy = i, then we have below equations:
d + 12i = 11410d + 10i = 150Simplify the second equation:
d + i = 15Subtract the second equation from the first:
d - d + 12i - i = 114 - 1511i = 99i = 9, ivy costs $9Now find d:
d = 15 - 9 = 6, daylilies cost $6Write the equation of a line with a slope of 3 that passes through (-3,2).
Answer:
y = 3x + 11
Step-by-step explanation:
Substitute the information into the point-slope form equation.
Point-slope form: y - y₁ = m(x - x₁)
y - 2 = 3(x - (-3))
y - 2 = 3(x + 3)
y - 2 = 3x + 9
y = 3x + 11

The quotient of a number and 6 minus -1/3 is equal to the quotient of the number and 8. What is the number?
Answer:
x = 8
Step-by-step explanation:
Let the number = x
x/6 - 1/3 = x/8
-1/3 = x/8 - x/6
-1/3 = (6x-8x)/48
-1/3 = -2/48x
Divide both sides by -2/48
x = -1/3 ÷ -2/48
= -1/3 × -48/2
= 48/6
= 8
x = 8
The number = 8

The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:

P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.
What angle relationship describes ∠UQR and ∠WRT? segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively Alternate interior angles Alternate exterior angles Corresponding angles Vertical angles
Answer:
Corresponding Angles
Step-by-step explanation:
I got it right on the test ;)
GOOD LUCK!
The angle ∠UQR and angle ∠WRT are the corresponding angles. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
The segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively.
Then the angle ∠UQR and angle ∠WRT are the corresponding angles.
Then the angle ∠UQR and angle ∠WRT are congruent to each other.
∠UQR = ∠WRT (corresponding angle)
Then the correct option is C.

How many solutions?
y = 5(x – 4)
4x + 12 = -y
Answer:
One solution, x = 8/9
Step-by-step explanation:
One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.
4x + 12 = -y
4x + 12 = -(5(x-4)) <--- substitution here
4x + 12 = -5(x-4)
4x + 12 = -5x + 20 <-- simplifying
4x + 5x = 20 - 12
9x = 8
x = 8/9

Take 9x² common from the expression on L.H.S.[tex]=> 9x^2(4x + 3) = 0[/tex]
Here, x will have 2 values :-
1) [tex]9x^2(4x + 3) = 0[/tex]
Divide both the sides by (4x + 3)[tex]=> \frac{9x^2(4x + 3)}{(4x+3)} = \frac{0}{4x+3}[/tex]
[tex]=> 9x^2 = 0[/tex]
Divide both the sides by 9x[tex]=> \frac{9x^2}{9x} = \frac{0}{9x}[/tex]
[tex]=> x = 0[/tex]
2) [tex]9x^2(4x + 3) = 0[/tex]
Divide both the sides by 9x²[tex]=> \frac{9x^2(4x + 3)}{9x^2} = \frac{0}{9x^2}[/tex]
[tex]=> 4x+3 = 0[/tex]
Substract both the sides from 3[tex]=> 4x+3 -3 = 0 - 3[/tex]
[tex]=> 4x=-3[/tex]
Divide both the sides by 4[tex]=> \frac{4x}{4} = \frac{-3}{4}[/tex]
[tex]=> x = -\frac{3}{4}[/tex]

A traffic cone has a diameter of 10 inches and a height of 27 inches.
Part A
Find the volume of the cone.
Answer:
V=706.85
Step-by-step explanation:
Well, first of when you want to find the volume of the cone you need to have a radius and hieght. And the radius is half the diameter, so divide the diameter into half: 10/2=5 in. and you already have the height so just plug in the numbers.
Formula: V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex][tex]r^{2}[/tex]h ---> V= [tex]\frac{1}{3}[/tex][tex]\pi[/tex]([tex]5^{2}[/tex])(27)
And put the plugged in formula in your calculator and you'll find the answer!
V=706.85
