Answer:
Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:
We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:
Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side
and we simplify:
now it's easy to solve for t:
And thus we arrive to the solution.
They get $85 for just getting in the truck and starting the engine.
To earn $100, they need another $15 for mileage.
$15 / 0.17 = 88.2 miles
Rounded to the nearest mile, it's <u>88 miles</u> (but that still leaves them 4¢ short).
Answer:
3/8x - 9 4/5
Step-by-step explanation:
Well we need to simplify the following expression,
So we need to distribute 3/4 to (1/2x - 12)
3/8x - 9 + 4/5
3/8x - 9 4/5
<em>Thus,</em>
<em>the answer is 3/8x - 9 4/5.</em>
