Itzzzzz 13/15 in simplest form
Answer:
x = 61
Step-by-step explanation:
To answer this question, we combine like terms:
44 + 59 + 74 = 177
The total will have to be 360, so....
177 + x + x + x = 360
or
177 + 3x = 360
360 - 177 = 183
So, 3x = 183
183 / 3 = 61
So, x = 61!

1000 ml costs £3.50
200 is 1/5 of 1000 so it will be £0.7
Answer:
The answer is given below
Step-by-step explanation:
The loads in the circuit are continuous duty, so the circuit can only loaded to 80% of its current rating.
Calculate 80% current rating of the circuit breaker.
Icb = [ 80/100] (20 A)
= (O.8) (20 A )
= 16 A
Now we assume that the value of supply voltage is 120 V
Now we will calculate current flows via under water light which will be taken as Load 1
<em>Ii = </em>500 W/120 V
= 4.167 A
Current via the circulating pump which will be taken as Load 2 IS 8.5 A
<em>I = </em>load1 + load 2
<em> = 4.167 A + 8.5 A</em>
<em> = 12.67 A</em>
The total current in the circuit obtained which is less than the circuit breaker rating current. Therefore, the power can be operated for both the loads.
Reason number 1 (before) is that you could contaminate your samples if you have foreign material on your hands.
Reason number 2 (after) is that you could spread<span>/or ingest dangerous chemicals or substances that you have handled in the lab.</span>
