The temperature inside a certain industrial machine at time t seconds after startup, for 0 < t < 10, is given by h(t) = 42

frutty [35]

Answer:

$t= \frac{125}{38} s$

Step-by-step explanation:

We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

$h(t)= 42 \cdot t +1 - 4\cdot t +2 (degrees \, C)$

We want to know at what time t the temperature inside the machine will be equal to 128 °C.

So we set:

$h(t)=128$

$42\cdot t+1-4\cdot t+2=128$

Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

$42\cdot t-4\cdot t=128-1-2$

and we simplify:

$(42-4)\cdot t= 128-2-1= 125$

$38 \cdot t = 125$

now it's easy to solve for t:

$t=\frac{125}{38}$

And thus we arrive to the solution.

Which of the following correctly uses absolute value to show the distance between -60 and 13? (5 points)

Sauron [17]

Answer:

l-60 – 13| = |-73| = 73 units

Step-by-step explanation:

Required

Distance between -60 and 13

Using absolute values, distance is calculated as:

$Distance = |Start - End|$

Where

$Start = -60$

$End = 13$

So, we have:

$Distance = |-60 - 13|$

$Distance = |-73|$

Take absolute value of -73

$Distance = 73$

<em>Hence, option A answers the question</em>

A bag of Hershey kisses cost $2.99 and the bag contains 11 ounces. How much would someone pay for 1 ounce?

Alexeev081 [22]

You would basically divide the cost of Hershey kisses by 11. So $2.99 /11 = 0.2718. Then, you would round the answer by the nearest hundredth. The answer would be about $0.27

Alex73 [517]

Answer:

8 1/2 hrs/wk

Step-by-step explanation:

3(1 1/2 hrs) plus

2(1 1/4 hrs) plus

2(3/4 hr)

The LCD here is 4. Convert 3(1 1/2 hrs) to 3(1 2/4 hrs), so that we now have:

3(1 2/4 hrs) = 3 6/4 hrs

+2(1 1/4 hrs) = 2 2/4 hrs

+2(3/4 hrs) = 6/4 hrs

-------------------------------------

5 14/4 hrs, or

5 + 3 2/4 hrs, or

8 1/2 hours/week
