the floor of a room is 12 m long and 6 m wide the floor of this room is to be fitted with tiles of dimension 10 cm x 2 cm what will the total expense in Rupees if the cost of tiling is 5 atile
Step-by-step explanation:
the price is 5 per tile ?
the area of the rectangular room is
12×6 = 72 m²
each m² has 100×100 = 10000 cm²
so, we have for the total area in cm²
72 × 10000 = 720000 cm²
one tile has 10×2 = 20 cm²
so, how many tiles will we need ?
720000 / 20 = 72000 / 2 = 36000 tiles.
so, if truly 1 tile costs 5 Rupees, then we have
36000 × 5 = 180000 Rupees as total costs.
Step-by-step explanation:
1 m = 100 cm
12 m = 1200 cm
6 m = 600 cm
Area of room = l × w
Area = 1200 × 600
Area = 720000 cm²
Area of tile = l × w
Area = 10 × 2
Area = 20 cm²
Total tile = 720000/20 = 72000/2 = 36000
Cost = 36,000 × 5
Cost = $ 180000

Answer:
(-2, 3)
Step-by-step explanation:
For x-4 you go left four places and y+6 go up 6 places
Answer:
(-2, 3)
Step-by-step explanation:
Point P has coordinates (2, -3).
The translation is (x - 4, y + 6) which means subtract 4 from the x-coordinate and add 6 to the y-coordinate.
The x-coordinate of point P is 2. Subtract 4 from it, you get -2.
The y-coordinate of point P is -3. Add 6 to it to get 3.
The coordinates of the translated point are (-2, 3).

Answer:
AC = AB + BC
18 = (2X - 4) + (3X + 2)
18 = 5X - 2 ( add/subtract like terms)
20 = 5X (-2 take over otherside - 18 + 2)
X = 4
SUB X INTO AB AND BC
AB = 2(4) - 4 = 4
BC = 3(4) + 2 = 14

4.5*4.5*45=911.25
is this correct answer
If BD = BC , BD = 5x - 26, BC = 2x+1, and AC = 43, find AB
Answer:
BD is congruent to BC. BD=BC
BD = 5x – 26, BC = 2x + 1, and AC = 43
To find out , we need to find BC first . For that we have to find out x
WE know that BD=BC, using that we solve for x
Now we plug in 9 for x and find out BC
BC=2x+1
BC=2(9)+1
BC=19
We know AC= 43
AC=AB +AC
43=AB+19
subtract 19
AB = 24

Which planets would you MOST LIKELY be able to see in the night sky without a telescope?
A)
Venus and Saturn
B)
Uranus and Jupiter
Neptune and Saturn
D)
Mercury and Neptune
Answer:
There are 5 planets visible without a telescope, Mercury, Venus, Mars, Jupiter, and Saturn (6 if you include Uranus for those with sharp eyes!). All of them plus Neptune move within 7 degrees of the ecliptic.
Venus. After the Moon, Venus is the brightest natural object in the night sky. It is both the Earth's closest neighbor in our Solar System and the planet most similar to Earth in size, gravity, and composition. We can't see the surface of Venus from Earth, because it is covered with thick clouds.
Step-by-step explanation:

Answer:
C. Neptune and Saturn
Explanation:
Neptune and Saturn are both considered 'giant planets'. Therefore, these planets are most likely to be visible from earth.

It takes 5 workers 3 days to build 120 birdhouses. How long will it take 3 workers to build 95 birdhouses?
Answer:
It will take [tex]3[/tex] workers to build [tex]95[/tex] birdhouses
Step-by-step explanation:
Given:
[tex]5[/tex] workers to built [tex]120[/tex] birdhouses[tex]=3[/tex] days
To find how long will it take [tex]3[/tex] workers to build [tex]95[/tex] birdhouses
By unitary method,
[tex]1[/tex] worker to built [tex]120[/tex] birdhouses [tex]=3[/tex] × [tex]5[/tex] days

60% discount? Explain your answer.
Answer:
No, It is not equal to a 60% discount.
Step-by-step explanation:
Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.

Factorise 3x²+5x-12
Show working out
hi <3
i'm not sure of which method you will have been taught but i'll try to explain the method i was shown.
so, you need to multiply the coefficient of x^2 by the last value
3 x -12 = -36
now, you need to find two values that multiply to make -36 but add to make 5.
9 and 4 would work. it would have to be positive 9 and negative 4, as these would subtract to give the 5 that you need
now we have:
(x - 4)(x + 9)
however, we need to achieve the 3 from somewhere so it needs to be divided somewhere
9 is divisible by 3 so you can divide it there. as 4 cannot divide by 3, you would move the 3 up to be the coefficient.
thus, your final answer would be:
(3x - 4)(x + 3)
hope this helps :)

You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path. a. Write a rule for the sequence using centimeters. The initial height is given by the term n = 1. b. What height will the ball be at the top of the sixth path?
A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm
B. A(n) = 1.5 • (0.74)^n–1 ; 0.33 cm
C. A(n) = 150 • (74)^n–1 ; 332,850,993,600 cm
D. A(n) = 0.74 • (1.5)^n–1 ; 5.62 cm
Answer:
A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm
Step-by-step explanation:
This is a geometric sequence.
a%5B1%5D=1.5m=150cm, r=0.74
The formula is
a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29
Just substitute a1 = 150cm and r = 0.74
a%5Bn%5D=150%280.74%29%5E%28n-1%29
That's the rule.
For the second part, substitute n = 6

Question 1
Find(f+g)(x)
f(x)=4x−4 and g(x)=2x^2−3x
Question 2
Find(f−g)(x)
f(x)=2x^2−2 and g(x)=4x+1
Question 3
Find(h⋅g)(x)
h(x)=3x−3 and g(x)=x^2+3
Question 4
Find(f/g)(x)and state the domain restriction.
f(x)=x+4 and g(x)=x+6
Step-by-step explanation:
Q1 . (f+g)(x) = f(x) + g(x)
=4x-4 +2x^2 -3x
= 2x^2 + x -4
Q2. (f-g)(x) = f(x) - g(x)
= 2x^2−2 - (4x+1)
= 2x^2 -2 -4x -1
= 2x^2 - 4x -3
Q3. h(x)=3x−3 and g(x)=x^2+3
(h.g)(x) = h(x) × g(x)
= (3x-3) × (x^2 + 3)
=3x^3 -3x^2 + 9x -9
Q4.f(x)=x+4 and g(x)=x+6
(f/g)(x) = f(x) ÷ g(x)
= x+4 / x+6
the domain restriction is x>-6
x<-6
x doesn't equal (-6)
If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,
(f + g)(x) = f(x) + g(x)
(f - g)(x) = f(x) - g(x)
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
(f . g)(x) = f(x) × g(x)
Question 1
f(x) = 4x - 4 and g(x) = 2x² - 3x
[tex](f+g)(x)=f(x)+g(x)[/tex]
Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]
[tex]=2x^2+x-4[/tex]
Question 2
f(x) = 2x² - 2 and g(x) = 4x + 1
Since, (f - g)(x) = f(x) - g(x)
Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)
= 2x² - 2 - 4x - 1
= 2x² - 4x - 3
Question 3
h(x) = 3x - 3 and g(x) = x² + 3
Since, (h - g)(x) = h(x) - g(x)
Therefore, (h - g)(x) = (3x - 3) - (x² + 3)
= 3x - 3 - x² - 3
= -x² + 3x - 6
Question 4
F(x) = x + 4 and g(x) = x + 6
Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]
