nata0808 [166]
Here is the answer to the problem above. So, if the monthly income is $300 and $50 was spent on clothing, we will find the percentage of $50 from $300 by dividing 50 by 300 then multiply the quotient by 100. So the answer is 16.67%. So the answer is 16.67%. Hope this answers your question.

What is the average rate of change of the function in the table at the interval x = -1 to x = 1?
Andre45 [30]

Answer:

the answer is undefined

Step-by-step explanation:

If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

Which is bigger? 1/3 foot or 5 inches? It can also be equal.
zhannawk [14.2K]

5 inches is bigger than 1/3 foot OR 1/3 foot is lesser than 5 inches. That is, 1/3 foot < 5 inches

4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards

8 yards is equal to 24 feet. That is, 8 yards = 24 feet

<h3>Calculating the value of a quantity </h3>

From the question, we are to determine which of the given quantities are bigger or equal

  • 1/3 foot or 5 inches

NOTE: 1 foot = 12 inches

If 1 foot = 12 inches

Then,

1/3 foot = 1/3 × 12

1/3 foot = 4 inches

∴ 5 inches is bigger than 1/3 foot. That is, 1/3 foot < 5 inches

  • 4 miles or 7,000 yards.

NOTE: 1 mile = 1760 yards

If 1 mile = 1760 yards

Then,

4 miles = 4 ×1760 yards

4 miles = 7040 yards

Hence, 4 miles is bigger than 7000 yards. That is, 4 miles > 7000 yards  

  • 8 yards or 24 feet

NOTE: 1 yard = 3 feet

If 1 yard = 3 feet

Then,

8 yards = 8 × 3 feet

8 yards = 24 feet

Hence, 8 yards is equal to 24 feet. That is, 8 yards = 24 feet
