The answer is 78

If you multiply 17x6 you get 102
102 equals the whole rectangle after that you need to get rid of the part that’s not there

The intensity of light bulb measured in watts per square meter (w/m^2), varies inversely as the square of the distance d from th

krek1111 [17]

Answer:

I(7) = 22.96 W/m²

Step-by-step explanation:

Let intensity of light, be I(d) where d is distance. There must be a proportionality factor K such as

I(d) = K /d²

Now for d = 5 m I(d) = K* 1/d²

then 45 * 25 = K

K = 1125

To find the intensity when the distance from the light bulb is 7 m away

I(7) = K / 49

I(7) = 1125/49 W/m²

I(7) = 22.96 W/m²

schepotkina [342]

Answer:

Step-by-step explanation:

Given:

Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.

Each sandwich costs the same amount.

The total amount cost of the sandwiches, including tax, is $54.36.

Question asked:

What is the cost of each sandwich including tax?

Solution:

Let cost of each sandwich including tax = $x$

Total number of sandwich = 2 + 1+ 1 = 4

As each sandwich costs the same amount and total amount of cost of 4 sandwiches, including tax, is $54.36, the equation will be:-

$x+x+x+x=\$54.36\\4x=\$54.36$

By dividing both sides by 4,

$x=\$13.59$

Thus, the cost of each sandwich including tax is $13.59
