Y varies directly with x it has a constant rate of change of 6. When the value of y is 11, then the value of x could be?

makvit [3.9K]

Answer: $\frac{11}{6}$

<u>Explanation:</u>

y varies directly with x means: $\frac{y}{x} = k$ ; where k is the rate

$\frac{y}{x} = k$
$\frac{11}{x} = 6$
$(x)\frac{11}{x} = 6(x)$
11 = 6x
$\frac{11}{6} =\frac{6x}{6}$
$\frac{11}{6} = x$

In △ABC, point P∈ AC with AP:PC=1:3, point Q∈AB so that AQ:QB=3:4, Find the ratios APBQ : APBC and AAQP : AABC.

weqwewe [10]

Answer: The ratios APBQ : APBC=4:21 and AAQP : AABC= 3:28

Explanation:

Here, ABC is a triangle where, P and Q are the midpoints of the edges AC and AB respectively,

Now, according to the question ,AP:PC=1:3 let AP=x and PC=3x where x is any real number. Thus, AC=AP+AC= x+3x= 4x

Similarly, AQ:QB=3:4 let AQ=3y and QB=4y where y is also any real number. Thus, AB=AQ+QB=3y+4y=7y

Since, $\frac{AP.BQ}{AP.BC} =\frac{AP.BQ}{AB.PC} =\frac{x.4y}{7y.3x} =\frac{4xy}{21xy} =\frac{4}{21}$

And, $\frac{AA.QP}{AA.BC} =\frac{AQ.AP}{AB.AC} =\frac{3y.1x}{7y.4x} =\frac{3xy}{28xy} =\frac{3}{28}$
