ach light bulb at Hotel California is either incandescent or fluorescent. At a certain moment, forty percent of the incandescent

Trava [24]

Answer:

10%

Step-by-step explanation:

The computation of the percentage of bulbs that switched on incandescent is as follows;

Let us assume the incandescent be I

And, the fluorescent be F

Now the equation is

0.4I + 0.9F = 0.8 (I+F)

0.41I + 0.9F = 0.8I + 0.8F

So here

0.4I = 0.1F

Now the percentage would be for incandescent in the case of switched on is

= 0.4I ÷ 0.8(I+F) × 100

= 0.1F ÷ 1F

= 10%

How many feet are in 30 yards?

melisa1 [442]

Hi!

For every 1 yard, we have 3 feet. So, in order to find out how many feet are in 30 yards - we must multiply 3 by 30.

3 * 30 = 90.

This means there are 90 feet in 30 yards.

Hopefully, this helps! =)

Find the value of x in the parallelogram

const2013 [10]

Answer:

$x=50$

Step-by-step explanation:

we know that

If LM is the midsegment

then

$LM=\frac{1}{2}(AB+DC)$

substitute the given values

$4x+3=\frac{1}{2}(x+8+348)$

Solve for x

$8x+6=(x+356)$

$8x-x=356-6$

$7x=350$

$x=350/7$

$x=50$
