Final answer:

The rate of change is 1 and the initial value is 1.

Explanation:

The table shows the points (2, 3), (4, 5), (6, 7), and (8, 9). To find the rate of change, we can calculate the difference in y-coordinates and divide by the difference in x-coordinates for any two points. Let's take the points (2, 3) and (4, 5) as an example:

The difference in y-coordinates is 5 - 3 = 2.

The difference in x-coordinates is 4 - 2 = 2.

The rate of change is 2 / 2 = 1.

To find the initial value, we can look for the y-coordinate when x is 0 or when the equation is of the form y = mx + b. In this case, the initial value is 1.

Answer:

35

Answer:

b = 35

Step-by-step explanation:

a and b make a right angle

a+b = 90

55 + b = 90

subtract 55 from each side

55-55 +b = 90-55

b = 35

Scientific Notation

The scientific notation for the product of 500 and 400 is 20 × [tex]10^4[/tex] and this can also be written as 2.0 × [tex]10^4[/tex]. So, options A and D are correct.

Given numbers are 500 and 400

Their product is 500 × 400 = 200000

This is a large number.

So, the power of 10 is positive and the scientific notation is written as:

200000 = 20 × [tex]10^4[/tex]

              = 2.0 × [tex]10^5[/tex]

Therefore, options A and D are correct. The product of 500 × 400 = 20 × [tex]10^4[/tex] = 2.0 × [tex]10^5[/tex].

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

Like terms are those terms that are having the same variables, also the variables are of the same order as well. The value of the x can be written as (4 + 2z)/(7 + y).

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

7x - 2z = 4 - xy

Bring like terms together,

7x + xy = 4 + 2z

Take x as common from the left side of the equation,

x(7 + y) = 4 + 2z

x = (4 + 2z)/(7 + y)

Hence, the value of the x can be written as (4 + 2z)/(7 + y).

Answer:

surface are: 300 cm2

volume: 450cm3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Surface area of a box = 2wl + 2hw + 2 lh

Where w is the width of the box, l is the length of the box, and h is the height of the box.

The top sides and bottom have only length and width, since there is no top side, the surface area is equal to the outer 5 surfaces.

S = wl + 2hw + 2 lh

Replacing with the values given:

S = (15x10)+ 2(3x10)+ 2(15x3)

S = 150+60+90=300 cm2

For the volume we simply apply:

Volume of a rectangular prism: length x width x height

V = 15x10x3 = 450cm3

Answer: 120 km/h

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate Hunk's time spent on his travel.

Speed rate = distance /time

Time = distance /speed = 540/ 90 =6 hours

Now, since Tim completed the same amount of distance with 1 hour and 30 min less (1.5) we have to subtract 1.5 hours to Hunk's time to calculate Tim’s time:

6-1.5 = 4.5 hours

Tim's speed rate = distance /time

s = 540/4.5 = 120 km/h

Final answer:

To determine the best deal, compare unit prices by dividing the price by the size of the items. Spend the $10.00 according to needs and preferences.

Explanation:

In order to determine which size is the best deal, Joy and John need to compare the prices per unit of the items they want to buy. They should divide the price of each item by its corresponding size to calculate the unit price. The item with the lowest unit price would be the best deal.

For example, if Joy wants to buy a 16oz bottle of soda for $1.50 and John wants to buy a 20oz bottle for $2.00, the unit price for Joy's soda would be $1.50/16oz = $0.09/oz, while the unit price for John's soda would be $2.00/20oz = $0.10/oz. Therefore, the 16oz bottle would be the best deal as it has a lower unit price.

As for how they should spend the $10.00, it would depend on their needs and preferences. They could evenly split the money and buy items separately, or they could pool their money together and buy a larger item.

Answer:

43.96 inches

Step-by-step explanation:

when you have the diameter of a circle, you just multiply it by pi and you will get the answer. since your diameter is 14, you multiply it by 3.14 and you will get 43.96 inches

Using π as 3.14, the circumference of the circle with a diameter of 14 inches is approximately 43.96 inches. This level of precision is suitable for most practical applications.

To find the circumference (C) of a circle, you can use the formula C = πd, where d is the diameter. In this case, the diameter is given as 14 inches.

Given the options of using either 22/7 or 3.14 for π, let's use 3.14 for this calculation.

C = 3.14 × 14

≈ 43.96 inches

Therefore, the circumference of the circle is approximately 43.96 inches when using π as 3.14. This means that if you were to wrap a string around the edge of the circle, it would take nearly 43.96 inches of string to complete one full loop.

It's important to note that using 22/7 for π is another approximation and yields a slightly different result, but for most practical purposes, 3.14 is accurate enough.

ANSWER: A

Step-by-step explanation:

Answer:

3,1,5,4,8,6 is 1.83 for mean absolute deviation

Step-by-step explanation:

The student correctly calculated the mean and the absolute deviations from the mean, but did not divide the sum of these by the number of data points to find the mean absolute deviation. The correct mean absolute deviation is 11 divided by 6, equal to 1.83 (rounded to two decimal places).

Based on your computations, it looks like you did correctly compute the mean absolute deviation (MAD). The first step is to find the mean (average) of the data set, which you correctly found to be 4.5 by summing the data points (3, 1, 5, 4, 8, 6) and dividing by the number of data points (6). Then, you correctly computed the absolute deviations from the mean for each data point (|1-4.5|, |3-4.5|, |4-4.5|, |5-4.5|, |6-4.5|, |8-4.5|), and summed these to get a total absolute deviation of 11. Finally, you divided this total by the number of data points (6) to find the mean absolute deviation. However, you missed this final division step in your calculations. The MAD should be 11/6 = 1.83 (rounded to two decimal places).
