Answer: Yes. The expression can be used to calculate how much Danielle has.
Step-by-step explanation:
The choir trip expenses are:
Train tickets = $77
Hotels = $106
Meals = $34
Total expense = $77 + $106 + $34 = $217
Since we are told that Danielle has a third of the amount needed for the trip. This means that we have to calculate 1/3 of $217 This will be:
= 1/3 × $217
= $72.33
Also, the expression (77+106+34) divided 3 shows the amount that Danielle has. Thus will be:
= (77+106+34) / 3
= 217/3
= 72.33

Answer: 1.75 amps
<u>Step-by-step explanation:</u>
V (voltage) = I (current) · R (resistance)
V = 3.5 (110)
= 385
When Resistance is doubled, the current is cut in half.
V = I R
385 = I (2 · 110)
1.75 = I
