Richard s kitchen floor measures 22 ft by 16ft. He plans on laying title down and each tile piece measures 16 inches by 16 inche
olya-2409 [2.1K]
We calculate the floor area of the kitchen:
 A = (22) * (16)
 A = 352 feet ^ 2
 We consider the following conversion:
 1 foot = 12 inches.
 Applying the conversion we have:
 A = 352 * (12/1) ^ 2
 A = 50688 in ^ 2
 We calculate the area of each tile:
 A = (16) * (16)
 A = 256 in ^ 2
 Then, the number of tiles is given by:
 N = (50688) / (256)
 N = 198
 Answer:
 He
 needs to buy 198 tiles

Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o
Katyanochek1 [597]
<h2>Answer:</h2>

\boxed{R_{4}=20\Omega}

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current  I is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance  of series combination and the four resistors as follows:

R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}

R_{eq} is the total resistance 50\Omega. Moreover:

R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega

Therefore:

50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}
