A pile of sand has a weight of 90 kg the sand is put into a small bag a medium bag and a large bag in the ratio 2:3:7

romanna [79]

Answer:

15 kg, 22.5 kg, 52.5 kg

Step-by-step explanation:

Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x

According to the given information:

$2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg$

Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg

Find the solutions to x2 = 24.

iren [92.7K]

Answer:

x = ± 2 $\sqrt{6}$

Step-by-step explanation:

Given

x² = 24 ( take the square root of both sides )

x = ± $\sqrt{24}$ = ± $\sqrt{4(6)}$ = ± $\sqrt{4}$ × $\sqrt{6}$ = ± 2 $\sqrt{6}$
