Two cylindrical containers are filled

Mathematics
1 answer:
sergey [27]4 years ago
4 0

Answer:

Once you know the volume of the displaced water, you can immediately determine its weight by multiplying by the density of water at the relevant temperature. That's because the definition of density (d) is mass (m) divided by volume (v), so m = dv.

The square of X varies inversely as the square root of Y and directly as the variable M. When M = 27 and Y = 16, then X = 9. Fin
irakobra [83]

Answer:

Y = 441

Step-by-step explanation:

Given

M = 27 when Y = 16 and X = 9

Required

Find Y when M = 7 and X = 2

We start by getting the algebraic representation of the given statement

X^2 \alpha \frac{1}{\sqrt Y} \alpha M

Convert the variation to an equation; we have

X^2 = \frac{KM}{\sqrt Y}

<em>Where K is the constant of variation;</em>

When M = 27; Y = 16; X = 9, the expression becomes

9^2 = \frac{K * 27}{\sqrt{16}}

This gives

81 = \frac{k * 27}{4}

Make K the subject of formula

K = \frac{81* 4}{27}

K = \frac{324}{27}

K = 12

Solving for Y when M = 7 and X = 2

Recall that X^2 = \frac{KM}{\sqrt Y}

Substitute values for K, M and X

2^2 = \frac{12 * 7}{\sqrt{Y}}

4 = \frac{84}{\sqrt{Y}}

Take square of both sides

4^2 = (\frac{84}{\sqrt{Y}})^2

16 = \frac{7056}{Y}

Make  Y the subject of formula

Y = \frac{7056}{16}

Y = 441
