Sam takes x minutes yo walk from home to library and 5 minutes more to walk from the library to school than fron home to the lib

LuckyWell [14K]

Answer:

$2x+5\ minutes$

Step-by-step explanation:

Given:

Sam takes x minutes yo walk from home to library.

And takes 5 minutes more to walk from the library to school than from home to the library.

Express the total time taken for Sam to walk from home to school via the library in terms of x.

Solution:

Time taken by Sam to walk from home to library = $x\ minutes$

Time taken by Sam to walk from library to school = $x+5\ minutes$

Total time taken by Sam to walk from home to school via the library = Time taken to walk from home to library + Time taken to walk from library to school

Total time taken = $x+x+5=2x+5$

Therefore, the total time taken for Sam to walk from home to school via the library is $2x+5\ minutes$

A map of a rectangular park has a length of 4 inches and a width olo and a width of 6 inches. It uses a scale of 1 inch for ever

Zielflug [23.3K]

Answer:

The actual area of the park is 21,600 miles square.

Step-by-step explanation:

Step 1: Calculate the area of the park

Area of rectangle = Length x width

Length = 4 inches

Width = 6 inches

Scale factor is given as, 1 inch = 30 miles.

So, converting the length and width in miles by using the scale factor, we get

Length = 4 * 30 = 120 miles

Width = 6 * 30 = 180 miles

The formula of finding the area of an rectangle is:

Area = length x width

By putting the values in equation, we get

Area = 120 x 180

Area = 21,600 miles square

Therefore, the actual area of the park is 21,600 miles square.

A body was found at 10 a.m. in a warehouse where the temperature was 40F. The medical examiner found the temperature of the body

lawyer [7]

Newton's law of cooling states that under forced convection (which is assumed to be true), then
dT(t)/dt = -k(T(t)-Ta)..............(1)
T(t)=temperature
Ta=ambient temperature=40F
k=cooling constant = 0.1947
T(0)=98.6F (assuming victim did not have fever)
Integrate (1)
T(t)-Ta=(T(t)-T(0))e^(-kt)
Solve for t
(T(t)-Ta)/(T(t)-T(0)) = e^(-kt)
take log:
-kt=log_e((T(t)-Ta)/(T(t)-T(0)))
substitute T(t)=80F, Ta=40F,T(0)=98.6F
-kt=log_e((80-40)/(98.6-40))=-0.38186
t=0.38186/0.1947
=1.96, or almost 2 hours (assuming k=0.1947 is in hours)
