Answer:

The difference is 5.

Step-by-step explanation:

The difference in math means subtraction, therefore, we need to find how many pints of strawberries she packs separately in the morning and in the afternoon:

3 pints ever 4 minutes.

60 minutes in an hour.

60 / 4 = 15 pints per hour.

2 pints of strawberries every 3 minutes in the afternoon.

60 / 3 = 20 pints per hour.

The difference between afternoon and morning **per** hour:

20 per hour - 15 per hour = 5

Difference is 5.

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.

A squares side are increased by five inches. Find the length of the original square if the perimeter of the new square is 100 in

Karo-lina-s [1.5K]

Answer:

The length of side of original square is: 20 inches

Step-by-step explanation:

Let x be the length of side of original square

Then x+5 will be the side of new square

Th formula for perimeter is:

$P = 4*side$

As we know the perimeter of the new square we can use the perimeter to find the value of x

$100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20$

The value of x is 20 inches.

Hence,

The length of side of original square is: 20 inches

Brut [27]

Answer:

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make it a 12% detergent solution. which equation c

Sliva [168]

The problem is about adding water to detergent solution to make a detergent solution.

In the problem g is taken for the number of gallons of water.

So, we can rephrase the given problem in simple words as

g gallons of water is added to 11 gallons of 18% detergent solution to get 12% detergent solution.

Let us write it in form of an equation,

g gallons of water is being added to 11 gallons of solution.

The total amount of solution will be (11 + g) gallons.

11 gallons of 18% detergent solution = 12% detergent solution.

For percent we can write over 100.

Therefore, above equation can be written as

11 × 18/100 = 12/100(g+11)

11 time 18 = 198

Therefore,

198/100 = 12/100(g+11)

Converting 198/100 into decimals, we get 1.98

We can rewrite above eqaution as

1.98 =12/100(g+11)

Dividing both sides by (g+11), we get

$\frac{19.8}{g+11}=\frac{12}{100}$

Therefore, correct option is D. 1.98/11+g = 12/100.

What is the value of x to the nearest tenth? <br> 2.8 <br> 4.2 <br> 4.8 <br> 6.9

lilavasa [31]

A^2 + b^2 = c^2
a = x
b = 14
c = x+10
x^2 + 14^2 = (x + 10)^2
( x^2 + 196 = x^2 + 20x +100 ) - x^2
( 20x +100 = 196 ) -100
( 20x = 96 ) / 20
x = 4.8
