Answer:
Step-by-step explanation:
breadth = x
length = 2x
Perimeter = 540m
2*( length + breadth ) = 540
2 *(2x + x) = 540
3x = 540/2
3x = 270
x = 270/3
x = 90 m
Breadth = 90m = 90 *100 = 9000 cm
Length = 2*90 = 180 m = 180 * 100 = 18000 cm
No.of bricks = Area of room/ area of one brick
= 9000 * 18000 / 20 * 12
= 675000 bricks
Answer:
I think true
Step-by-step explanation:
i am not sure but f(1)=5 hereA=1 andB=5 so i belif this is true function
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
Answer:
S: 24x - 72
S and T are not equivalent for any value of x
Step-by-step explanation:
S: 4(6x-18) = 4 * 6x - 4 * 18 = 24x - 72
S and T are not equivalent for any value of x, x+1 S: 24 - 72 = - 48 T: 24 - 18 = 6
