The formula K=5/9(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.

FromTheMoon [43]

Answer:

a. F = (9/5)(K - 273.15) + 32

b. F = 32°F

Step-by-step explanation:

K=5/9(F−32)+273.15

F = (9/5)(K - 273.15) + 32

F = (9/5)(<u>273.15</u> - 273.15) + 32

F = 32

A person’s theoretical maximum heart rate (in heartbeats per minute) is 220 - x where x is the person’s age in years (20 ≤ x ≤ 6

Lyrx [107]

Let f(x) represents the heart beat of the person.

Now, we have been given that person’s theoretical maximum heart rate is given by 220 - x.

Also, we have been given that person strive for a heart rate that is at least 50% of the maximum. At least means greater than equal to.

Thus, we have

$f(x)\geq (220-x)0.5\\
f(x)\geq 110-0.5x$

Also, we have been given that person strive for a heart rate that is at most 75% of the maximum. At most means less than equal to.

$f(x)\leq (220-x)0.75\\
\\
f(x)\leq 165-0.75x$

Therefore, the system of inequality is given by

$f(x)\geq 110-0.5x\\
f(x)\leq 165-0.75x$

The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees, and the

Helen [10]

Answer:

67.5 degrees

Step-by-step explanation:

The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)

We know the 3 angles of a triangle add to 180 degrees

45+x+x = 180

Combine like terms

45+2x=180

Subtract 45 from each side

45-45 +2x = 180-45

2x= 135

Divide by 2

on each side

2x/2 =135/2

x = 67.5
