Answer:
X ball bearings can be produced in 1 hour and 20 minutes
Step-by-step explanation:
Proportions
Proportions serve as an essential method for solving various common challenges. We understand that:
Company ABC manufactures X ball bearings in 3 hours.
Company DEF produces X ball bearings in 4 hours.
Company GHI generates X ball bearings in 6 hours.
In a single hour, each company is capable of producing:
ABC: X/3 ball bearings
DEF: X/4 ball bearings
GHI: X/6 ball bearings
By collaborating, they can produce

ball bearings. Operating together

If their output is 3/4 of a ball bearing in one hour, then it will take
hours to create one complete ball bearing. This translates to 1 hour and 20 minutes.
X ball bearings can be produced in 1 hour and 20 minutes
To determine the answer, you need to divide 405 by 50 to discover the weight of a single coin. The calculation should appear like this:

= 8.1
The precise weight is 8.1 grams, but if you are looking for an estimate, the conclusion should be
Approximately 8 grams for a one-dollar coin
Answer:


Step-by-step explanation:
Step 1:-
We have c1(t) = e^ t i + (sin(t))j + t³k
and c2(t) = e^−t i + (cos(t))j − 6t³k.
By adding c1(t) and c2(t):
c1(t)+c2(t) = e^ t i + (sin(t))j + t³k + e^−t i + (cos(t))j − 6t³k
Now, employing the derivative formula:


Next, differentiate with respect to 't'

By factoring out i, j, and k terms, we arrive at:

4 pounds cost $1.96
1.96 / 4 gives $0.49 per pound.
