The average temperatures for two of the world's hottest places are given. Determine which location has the warmer average temper
zubka84 [21]

Answer: City A, 0.28^{\circ}C

Step-by-step explanation:

Given

The temperature of city A is 86.7\ ^{\circ}F

The temperature of city B is 30.1^{\circ}C

We know, 32^{\circ}F=0^{\circ}C

So, 86.7^{\circ}F=30.38^{\circ}C

30.38>30.1

Clearly, the average temperature of city A is more than city B

The difference in temperature is 30.38-30.1=0.28^{\circ}C

What is equivalent to 4 times the sum of 3 and x
Maslowich

Answer:

\huge\boxed{\bf\: 4 (x + 3) \: and \:  4x + 12 }

Step-by-step explanation:

Let the variable be 'x'.

  • Sum of 3 and x = x + 3
  • 4 times the sum of 3 and x = 4 (x + 3)

Expression : 4 (x + 3)

On expanding ,

4 (x + 3)

= (4*x) + (4*3)

= 4x + 12 ⟶ equivalent expression to the statement .

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
