Answer:

Total = 3\frac{1}{5}ft

Step-by-step explanation:

Given

Pieces = 4

Size = \frac{4}{5}ft

Required

Determine the total size of the string

To do this, we multiply the number of pieces by the length of each piece.

Total = Pieces * Size

Total = 4 * \frac{4}{5}ft

Total = \frac{4 * 4}{5}ft

Total = \frac{16}{5}ft

Convert to mixed number

Total = 3\frac{1}{5}ft

An element with mass 780 grams decays by 16.3% per minute. How much of the element is remaining after 16 minutes, to the nearest
vitfil [10]
Exponential decay is a very common process especially when we are talking about radioactive materials. So, there is already a common formula for this type of behavior which is written below:

A = Pe^-rt
where
A is the amount left after time t
P is the initial amount at t=0
r is the rate

Substituting the values,
A = (780 g)(e^-0.163*16)
A = 57.5 g

Two lines are intersecting. What is the value of x? Enter your answer in the box.
Romashka-Z-Leto [24]

Answer:

x = 19

Step-by-step explanation:

To find the value of x, you set the equations as equal to each other:

x+23 = 2x+4

Then you simplify:

23 = 2x + 4 - x\\23 = x + 4\\23-4 = x\\19=x

In 1911, the temperature in Rapid City,
Sliva [168]

The 3.1 °F/min rate of change of the temperature and 15 minutes change duration gives the change in temperature as 46.5 °F

<h3>How can the change in temperature be found from the rate of change?</h3>

The rate at which the temperature changed = 3.1 °F/min

The duration of the change in temperature = 15 minutes

The relationship between the change in temperature, the rate of change in temperature and the time can be presented as follows;

3.1  ^{\circ} F/min =  \frac{ \delta T }{\delta t}  =  \frac{ \Delta T }{ \Delta t}

Where;

∆T = The required change in temperature

∆t = The duration of the change = 15 minutes

Which gives;

∆T = 3.1°F/min × 15 minutes = 46.5 °F

  • The change in temperature, ∆T = 46.5 °F
