Answer: ₹2646
Step-by-step explanation:
Given
The volume of the room is [tex]V=270\ m^3[/tex]
cost of painting the walls is ₹[tex]3600[/tex] at the rate of [tex]15\ m^2[/tex]
So, the area of walls is
[tex]\Rightarrow A=\dfrac{3600}{15}\\\\\Rightarrow A=240\ m^2[/tex]
This the area of 4 walls i.e.
[tex]\Rightarrow 240=2[hl+hb]\\\Rightarrow 120=h[l+b]\\\Rightarrow 120=4bh\quad [\text{length is thrice of width}]\\\Rightarrow 30=bh\qua \ldots(i)[/tex]
The volume of the room is given by
[tex]V=l\times b\times h\\270=3b\times b\times h\\90=hb^2\quad \ldots(ii)[/tex]
Divide (i) and (ii)
[tex]\Rightarrow \dfrac{90}{30}=\dfrac{b^2h}{bh}\\\\\Rightarrow b=3\ m[/tex]
So, the length of the room is
[tex]l=3b\\l=3\times 3\\l=9\ m[/tex]
The area of the floor is
[tex]\Rightarrow A_o=l\times b\\\Rightarrow A_o=9\times 3\\\Rightarrow A_o=27\ m^2[/tex]
The cost of flooring is
[tex]\Rightarrow 27\times 98\\\Rightarrow Rs.2646[/tex]

Step-by-step explanation:
A polynomial has zeros x = 2, x = 0, X = 1, X = 2
What is the polynomial in factored form?
A) f(x) = x(x - 2)(x + 1)(x + 2)
B) f(x) = x(x + 2)(x-1)(x + 2)
C) f(x) = x2(x + 2)(x - 1)(x - 2)
D) f(x) = x(x + 2)(x - 1)(x - 2)
Answer:
f(x)= x(x+2)(x-1)(x-2)
Step-by-step explanation:
before taking the zeros each zeros were in the forrm
x+a=0 where 'a' is any number
then after taking the zeros, the zeros were in the form x=0 x=2 x=1
so we are gonna take then back to the form before taking the zeros
Find the rate of change from the table.
==================================================
We're asked to find the slope:
m = slope
m = (y2-y1)/(x2-x1)
m = (50-20)/(4-2)
m = 30/2
m = 15
The rate of change is 15. Each time x goes up by 1, y increases by 15.
slope = rise/run = 15/1
rise = 15, run = 1
I used the middle two columns of the table, but you could use any two columns you want. I subtracted the y values together to get the change in y, which is the rise. The change in x, aka run, is the difference in x values. You must subtract the values in the same order. If done in the wrong order, you might get -15 as the incorrect answer.

Answer:
c = 3
Step-by-step explanation:
Given
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{c^2-4}[/tex] ← factor the difference of squares
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{(c-2)(c+2)}[/tex]
Multiply through by (c - 2)(c + 2) to clear the fractions
2(c + 2) - 3(c - 2) = 7 ← distribute and simplify left side
2c + 4 - 3c + 6 = 7
- c + 10 = 7 ( subtract 10 from both sides )
- c = - 3 ( multiply both sides by - 1 )
c = 3

You have 30 minutes to exercise at the gym. The Stairmaster burns 7 calories per minute, while the stationary bike burns 12 calories per minute. You want to burn 290 calories total using both machines. How much time should you spend on each machine?
Answer:
14 min on Stairmaster
16 min on Bike
Step-by-step explanation:
s = time on Stairmaster
b = time on bike
System of Equations:
s + b = 30
7s + 12b = 290
let 's' = 30-b
Substitution Method:
7(30-b) + 12b = 290
210 - 7b + 12b = 290
5b + 210 = 290
5b = 80
b = 16
s + 16 = 30
s = 14

Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
Step-by-step explanation:
If it went from f(x) ⟹ f(0), that means that x=0.
So, you would plug in 0 for x in f(x)=-8(2)^x-12.
After plugging in the value of x, x=0, into the equation, you should have
f(0)=8(2)^0-12
Now, we are solving for f(0) (or f(x)).
You would use PEMDAS to solve this:
P-PARENTHESIS
E-EXPONENT
M-MULTIPLICATION
D-DIVISION
A-ADDITION
S-SUBTRACTION
There are no parenthesis
there are exponents,
(2)^0 and that =1
so we have f(0)=8(1)-12
there is multiplication, 8(1) which =8
so now we have f(0)=8-12
there is no division
there is subtraction
8-12, which equals -4
f(0)=-4
What is the equation, in standard form, of a circle with center (−5, 8) and radius 5?
Enter your answer by filling in the boxes.
Answer:
( x + 5 )² + ( y - 8 )² = 25
Step-by-step explanation:
Standard form for the equation of a circle - ( x - h )² + ( y - k )² = r²
Where r = radius and Center is located at ( h , k )
We are given that the center is at ( -5 , 8 )
Thus, h = -5 and k = 8
We are also given that the radius = 5
Thus, r = 5
Now we just plug all of the given values into the standard form equation
( x - (-5))² + ( y - 8 )² = 5²
*simplify*
in - ( - 5 ) the two negative sign cancel out and it turns into + 5
5² = 25
Thus, the equation is ( x + 5 )² + ( y - 8 )² = 25
A type of fish for your aquarium costs $8 each. You can spend at most $48. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.
Answer:
x ≤ 6
Step-by-step explanation:
Cost of fish = $8
You can spend at most $48
How many of these fish can you buy?
Let
x = number of fishes you can buy
The inequality is
8x ≤ 48
Divide both sides by 8
x ≤ 48/8
x ≤ 6

If the length between points on a map is 6 inches, 8 inches, and 9 inches, and the scale is one inch equals 5 miles, find
the distances in miles
12.16 and 18 miles
11, 13 and 14 miles
30,40 and 45 miles
Given:
The length between points on a map is 6 inches, 8 inches, and 9 inches.
The scale is one inch equals 5 miles.
To find:
The distances in miles.
Solution:
The given scale is:
1 inch = 5 miles
Using this scale, we get
6 inches = 6 × 5 miles
= 30 miles
8 inches = 8 × 5 miles
= 40 miles
9 inches = 9 × 5 miles
= 45 miles
The distance is miles are 30, 40, 45 miles.
Therefore, the correct option is C.
