Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?

Hi :)

Rate of change is the change in the y divided by the change in x

Here's the formula

R = (∆y / ∆x )

R = rate of change

∆y = change in y

∆x = change in x

Answer:

16 2/3 per a mile

Step-by-step explanation:

50 ounces of blueberries/3 miles = 16.666 repeated

16.666 repeated = 16 2/3 ounces/mile

Answer: Sanjay picked 16.66 ounces each mile

Step-by-step explanation:

For this exercise let "x" represents the amount of ounces of blueberries that Sanjay picked each mile, along the 3-mile walking path.

According to the information given in the exercise, you know that Sanjay picked a total amount of 50 ounces of blueberries along the walking path.

Then, knowing that the length of that walking path is 3 miles, you can set up the following proportion:

\(\frac{3}{50} = \frac{1}{x}\)

Now, the next step is to solve for "x" in order to find its value.

You get that this is:

\((x)(\frac{3}{50} )=1\\\\x=(1)(\frac{3}{50} )\\\\x=16.66\)

Therefore, knowing the value of "x", you can conclude that Sanjay picked 16.66 ounces of blueberries each mile.

16.66 = 16 2/3

Answer:

50

Step-by-step explanation:

When n = 6, the length is 3 * 6 + 2 = 20 and the width is 6 - 1 = 5. We know that the perimeter of the rectangle is twice the sum of its length and width. The sum of the length and width is 20 + 5 = 25 and twice that is 25 * 2 = 50.

Answer:

50

Step-by-step explanation:

At the bottom we see n = 6, that's already solved for us so now we plug it into the equation.

3n+ 2 and n - 1, When a variable is next to a number, you multiply the number of the variable and the original number together, So in this case n = 6 and we have 3n + 2, 3n = 18 (3x6) and then 18 + 2 = 20. And since n = 6, N - 1 = 5 (6-1) So we add the first sum of 3n+2 = 20 + N - 1 = 5 which gives us 25. Now that we have our sum of width and length we multiply that by 2 in order find the perimeter. 25x2 = 50.

Answer:

1/0 = 0

Step-by-step explanation:

The fraction bar means "divided by", which means that the fraction 1/0 is 1 divided by 0. Any fraction in which the denominator is 0, is an improper fraction, meaning the answer is always 0. So, 1/0, or 1 divided by 0 is 0.

Answer:

a) Missing y-values
x = - 2    ==>   y = 5

x = - 1     ==>   y = 2

x =   1    ==>    y = 2

x =   3   ==>    y  = 10

b) Values of x for y = 4:
x = 1.7 and x = -1.7

Step-by-step explanation:

Given the quadratic function,
y = x² + 1

part a)

to find the y-value for a specific x, just plug in that value of x into the right side and simplify

There are four missing values for

The x values and the corresponding y values are
x = - 2    ==>   y =  (-2)² + 1   =  4 + 1 = 5

x = - 1     ==>   y  =  (-1)²  + 1  =  1 + 1 = 2

x =   1    ==>    y  =   (1)²  + 1  = 1 + 1  = 2

x =   3   ==>    y   =  (3)²  + 1  = 9 + 1 = 10

part b)

The graph has each unit on the grid for the x-axis = 0.5
and
each unit on the grid for the  y-axis  = 2

I got this by seeing that between x = 0 and x = 1 there are two units

the value of y at x = -1 or x = 1 is only one vertical unit on the grid and since y = 2 for these values of x, each vertical unit must be 2

Therefore look at the value of y = 4 (which should be two vertical units) on the graph. You can also draw a horizontal line parallel to the x axis at 2 units from the x-axis

It appears that on the positive x-axis for y = 4, x is about halfway between 1.5 and 2 so I would estimate it at 1.75

On the negative x-axis, at y = 4, x is about halfway between -1.5 and -2 so it would be -1.75

One thing to note about quadratic functions is that you get the same value of y for x and -x

So at y = 4, the two possible values of x are
x = 1.75 and x = -1.75

which when using one decimal place will round to 1.7 and 1;75

I am rounding down rather than rounding up since the x value appears be less than 1.75

Mathematically we can solve for x at y = 4 by plugging in values
y = 4 = x² + 1

x² + 1 = 4

x² = 4 - 1 = 3

x =±√3 = ±1.732

which when rounded to 1 decimal place becomes
x = 1.7 and x = -1.7

Answer:

Step-by-step explanation:

a) y = (-2)² + 1 = 5

y = (-1)² + 1 = 2

y = (1)² + 1 = 2

y = (3)² + 1 = 10

b)  4 = x² + 1

x² = 4 - 1 = 3

x = ±√3 = ±1.7

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.

Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.
