Answer:

Yes, it will be 1,650 alarms

Step-by-step explanation:

All you needed to do was divide 198 by 12, since it's 12%, to find the unit rate. That multiplied by 100 is 1,650.

A rhombus has sides of length 12 cm and an angle of 72 degrees. Find its area.
Natalka [10]
Diagonals of rhombus are perpendicular
area is (1/2)*d1 * d2 where d1 and d2 are the diagonal lengths
draw the diagonals on your rhombus and you will see a 30-60-90 triangle and then figure
sides will be 6 , 6√3 . 12
so d1 is 2*6 = 12
and d2 is 2*6√3 = 12√3
and area = (1/2)*12*12√3
= 72√3 square cm.

Proportion problems

An example is:

y is directly proportional to x such that: y=4 when x = 2;

Derive the equation

For direct proportions, we have:

y\ \alpha\ x

This gives:

y = kx

Make k the subject

k = y/x

So:

k = 4/2 =2

So, the equation is:

y = kx

y = 2x

Assume the above question is for inverse proportion

The variation will be:

y\ \alpha\ \frac{1}{x}

This gives:

y\ = \frac{k}{x}

Make k the subject

k =x*y

k =2* 4 = 8

So, the equation is:

y\ = \frac{k}{x}

y = \frac{8}{x}
