Answer:
0.004462m²
612000m²
0.0482m²
Step-by-step explanation:
Using the conversion
1mm² = 10^-6m²
4462mm² = x
Cross multiply
1 * x = 4462 * 10^-6
x = 4462 * 10^-6
x = 4.462 * 10^3 * 10^-6
x = 4.462*10^{3-6}
x = 4.462*10^-3
x = 0.004462m²
Hence 4462 mm² in m² is 0.004462m²
0.612 km² in m²
1km² = 10^6m²
0.612km² = y
Cross multiply
1 * y = 0.612 * 10^6
y = 0.612*1,000,000
y = 612000m²
Hence 0.612 km² in m² is 612000m²
482 cm² in m²
1cm² = 0.0001m²
482 cm² = z
z = 482 * 0.0001
z = 0.0482m²
Hence 482 cm² in m² is 0.0482m²
The two diagonals intersects at right-angle for a kite
the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3
QPR is a right-angle triangle with QR at 5 and QR at 3
RP = sqrt (5^2 - 3^) = 4m
Answer:
(4 * 5)^3 ;
8000
Step-by-step explanation:
Andre's statement :
Multiply 4 by 5 = 4 * 5 = 20
Cube the result = 20³
The equal expression from the option :
A.) (4 * 5)^3
Also, (4 * 5)^3 = 20^3 = 20 * 20 *20 = 8000
Answer:
A = 76.85
B =65.28
Step-by-step explanation:
(30/100)A = 10 + (20/100)B
0.3A - 0.2B = 10 ...... equation (i)
(30/100)B + 35 = (20/100)A
0.2A - 0.3B = 35 ........ equation (ii)
From equation (i)
0.3A = 10 - 0.2B
A = (10 - 0.2b) / 0.3
A = 33.33 - 0.67B ........equation (iii)
Put equation (iii) into equation (ii)
0.2(33.33 - 0.67B) - 0.3B = 35
6.67 - 0.134B - 0.3B = 35
0.434B = 35 - 6.67
B = 28.33 / 0.434
B = 65. 275 = 65.28
Put B = 65.28 into equation (i)
0.3A - 0.2B = 10
0.3A - 0.2(65.28) = 10
0.3A - 13.056 = 10
0.3A = 10 + 13.056
A = 23.056/ 0.3
A = 76.85
