1/2+1/4 is going to turn into 4/8+2/8=6/8 couse u need to find the common denominator and multiply the top with the number u multiple to get the number in the denominator and than u simlify it to 3/4
Answer:
384 lamps
Step-by-step explanation:
This is simply a multiplication problem. From the question, we know that each fixture needs 4 lamps with a single room needing 16 fixtures.
The number of lamps required by each room is thus 16 * 4 = 64 lamps
Now, the total number of lamps required by 6 rooms is thus 64 * 6 = 384 lamps
Parallel means lines that never meet, and perpendicular are lines that meet at right angles.
There were 2 solutions that i came up with. Here is the first one. I rearranged the eqaution by subtracting what is to the right of thr equal sign. Multiply the coefficeint of the first term by the constant 5 x (-1)= -5. Then you would find 2 factors of -5 whose sum equals the coefficient of the middle term which is 20. -5+1= -4 and -1+5=4. the eqaution then comes to 5t^2-20t-1=0. you would solve 5t^2-20t-1=0. you would divide both sides of the equal sign by 5. t^-4t-1/5=0. then t^2-4t=1/5. add 4 to both sides of the equation. so we get 21/5+ 4 + 4t -t^2=21/5. it then comes out to be t^2-4t+t=t-2^2. according to the law of transitivity it is t-2^2=21/5.
t =(20+√420)/10=2+1/5√<span> 105 </span><span>= 4.049 </span>.
