Suppose coffee is initially brewed at 205 F and the room temperature is 70 F. Determine the value of kk if the temperature of the coffee drops from 205 F to 200 F in the first two minutes after brewing. Round answer to 4 decimal places.

Answers

Answer:

0.0189

Step-by-step explanation:

We solve for this using Newton's Law of cooling.

The formula for Newton's Law of cooling =

T −Ts = (To−Ts)e^-kt

T = Temperature after cooling

To = Initial temperature

Ts = Room temperature

k = constant

t = time = 2 mins

(200 - 70) = (205 - 70)e^-2k

130 = 135e^-2t

e^-2k= 130/135

k = In(130/135)/-2

k = 0.018870164

Approximately to 4 decimal places = 0.0189

Therefore, the value of k = 0.0189

Troy and Lisa were shopping for school supplies. Each purchased different quantities of the same notebook and thumb drive. Troy bought five notebooks and five thumb drives for $110. Lisa bought three notebooks and five thumb drives for $102. Find the cost of each notebook and each thumb drive.

Answers

Answer:

Notebooks cost $4

Thumb drives cost $18

Step-by-step explanation:

x=$ for notebooks

y=$ for thumb drives

5x + 5y = 110 ----> for Troy

3x + 5y = 102 ----> for Lisa

Use subtraction to find x.

(5x + 5y = 110)

-(3x + 5y = 102)

_____________

2x + 0y = 8

2x = 8

x=4

Sub 4 for x into 5x + 5y = 110

20 + 5y = 110

-20 -20

___________

5y = 90

y=18

Notebooks cost $4

Thumb drives cost $18

The speed of light is about 1.86×10^5 miles per second. The star Sirius is about 5.062×10^13 miles from Earth. About how many seconds does it take light to travel from Sirius to Earth? Write your answer in scientific notation, rounded to the nearest hundredth.

Answers

The number of seconds it takes light to travel from Sirius to Earth is $2.72*10^(8)$ .

Given that, the speed of light is about 1.86×10^5 miles per second. The star Sirius is about 5.062×10^13 miles from Earth.

We need to find out how many seconds it takes light to travel from Sirius to Earth.

What is scientific notation?

To determine the power or exponent of 10, let us understand how many places we need to move the decimal point after the single-digit number.

If the given number is multiples of 10 then the decimal point has to move to the left, and the power of 10 will be positive.
If the given number is smaller than 1, then the decimal point has to move to the right, so the power of 10 will be negative.

Let the number of seconds it takes light to travel from Sirius to Earth be n seconds

Now, the proportion= $(1.86*10^(5))/(1) =(5.062*10^(13))/(n)$

⇒ $n=(5.062*10^(13))/(1.86*10^(5))$

⇒ $n=2.72*10^(13-5)=2.72*10^(8)$

Therefore, the number of seconds it takes light to travel from Sirius to Earth is $2.72*10^(8)$ .

Answer:

2.72 × 10^8 seconds

Step-by-step explanation:

1. Organize the given information to help you create the equation:

- Light travels 1.86 × 10^5 miles per 1 second

- Light travels 5.062 × 10^13 miles per n seconds

- Need to solve for n

2. Set up the equation (Make sure that both numerators and both denominators match units, so the seconds are either both on top or both on bottom, NOT switched):

$(1.86 * 10^5)/(1)$ = $(5.062 * 10^1^3)/(n)$

3. Cross multiply (Multiply the first fraction's numerator by the second's denominator, and vice versa. It doesn't matter what number is on which side of the = sign)

n × (1.86 × 10^5) = 5.062 × 10^13

4. Solve for n by isolating the variable and dividing.

$(n (1.86 * 10^5))/(1.86 * 10^5)$ = $(5.062 * 10^1^3)/(1.86 * 10^5)$

n = $(5.062 * 10^1^3)/(1.86 * 10^5)$

n = 2.72 × 10^8 (Make sure to include the unit, seconds)
