Dale says the ratios 3:5 and 2:10 are equivalent. Is He correct? Explain

Mnenie [13.5K]

Answer:

No, Dale Isn't correct because 3:5 is greater than 2:10

Step-by-step explanation:

3:5 and 2:10 is the same as in $\frac{3}{5}$ and $\frac{2}{10}$

First Find the least common denominator or LCM of the two denominators:

LCM of 5 and 10 is 10

Next, find the equivalent fraction of both fractional numbers with denominator 10

For the 1st fraction, since 5 × 2 = 10,

$\frac{3}{5} =\frac{3*2}{5*2} =\frac{6}{10}$

Likewise, for the 2nd fraction, since 10 × 1 = 10,

$\frac{2}{10} =\frac{2*1}{10*1} =\frac{2}{10}$

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

$\frac{6}{10} >\frac{2}{10} Or\frac{3}{5} >\frac{2}{10}$

Hence, $\frac{3}{5}$ is Greater than $\frac{2}{10}$

Hence, 3:5 is Greater than 2:10

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt.

Mariulka [41]

This problem requires the use of the chain rule: dy / dt = [dy / dx] * [dx / dt]

y = √x => dy / dx = 1 / (2√x)

(a) Find dy/dt, given x = 16 and dx/dt = 7.

dy/dt = [ 1/(2√x) ] * 7 = [1/(2*4)] * 7 = 7/8

(b) Find dx/dt, given x = 64 and dy/dt = 8.

dx/dt = [dy/dt] / [dy/dx] = 8 / [1/(2√64) ] = 128
