50 x 8½
The only cubic number between 400 and 600 is 8 x 8 x 8 (83) = 512.
8 x 50
300 x 40 = 12000 300 x 8 = 2400 50 x 40 = 2000 50 x 8 = 400 7 x 40 = 280 7 x 8 = 56
The thickness does not enter into the calculation (400)/(4x32) = 100/32 = 25/8 = 3 and 1/8 No one would sell you 3 and 1/8 boards, hence buy 4 boards
To find the percent of a number, you have to make a ratio. 8 x 400 = 100 You have to cross multiply: 800=400x and divide. 800/400=x 2=x 2% of 400 is 8.
50 x 8 = 400 So there are 8 50s in 400.
50 x 8½
400 x 80 = 4 x 100 x 8 x 10 = 4 x 8 x 1000 = 32000
400 = 1 x 400 400 = 2 x 200 400 = 4 x 100 400 = 5 x 80 400 = 8 x 50 400 = 10 x 40 400 = 16 x 25 400 = 20 x 20
400 is the LCM. 8 x 50 = 400 20 x 20 = 400 16 x 25 = 400 100 x 4 = 400
Simple interest 400 + (4 x 5 x 8) = 400 + 160 = 560; Compound interest 400 x 1.085 = 400 x 1.47* = 588. *Actually the multiplier is 1 .469
The only cubic number between 400 and 600 is 8 x 8 x 8 (83) = 512.
8 x 50
Possibly 400' x 400' x 8'
8/2 x 100 = 400 Therefore, 8 is 400 percent of 2.
