How To Do This Problem In The Picture 8th Grade Math

Answers

Answer 1

Answer:

4.69 x 10⁵

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 469,000

New Number: 4.69000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 4 . 6 9 0 0 0

Decimal Count: 1 2 3 4 5

There are 5 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 4.69 (Please notice any zeroes on the end have been removed)

b = 5

Now the whole thing:

4.69 x 10⁵

Step 4

Check your work:

105 = 100,000 x 4.69 = 469,000

Answer 2

Answer:   [tex]4.61 \times 10^5[/tex]

Reason:

The original number is 461,000 or 461000

Place a decimal point between the first two nonzero values. Erase the zeros and we get 4.61

To get back to 461000, we need to move the decimal point 5 spaces to the right. This is the exponent for the [tex]10^5[/tex] portion.

So [tex]461,000 = 4.61 \times 10^5[/tex]

The required intersection would be at the point (55, 460) in the given graph which shows a round of golf is 55 and a total cost is $460.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

We have been given that the graph represents the following situation.

Golfers must first pay a $75 membership fee and an additional $7 for each round of golf in order to play at Gulf Shores Range.

Golfers at the Royal Estates Country Club pay $5 for each game of golf, but membership costs $185.

Since the x-axis represents a round of golf and the y-axis represents a total cost.

According to the graph,

Here is a round of golf = 55 and a total cost = $460

So the intersection represents this situation at the point (55, 460).

Therefore, the required intersection would be at the point (55, 460) in the given graph.

5 3/8 as a whole number

Answers

Answer:

Exact Form: 43/8

Decimal Form: 5.375

Rounding to the Nearest whole number: 5

5.3 ………………………………………..

Write the sentence as an inequality. 7/8 is at most the difference of twice a number m and 5/4 .

Answers

The inequality stated may be expressed as 2m - 5/4 ≤ 7/8.

What exactly is inequality?

There are four sorts of inequality.

A < B means that A is less than B.

A > B means a is greater than B.

A ≥ B, a is bigger than or equal b.

A ≤ B, a is less than or equal.

In light of the posed query

The maximum difference between two numbers, m and 5/4, is equivalent to an inequality of the form 2m - 5/4 < 7/8.

The difference between two numbers, "m," and 5/4 is 2m - 5/4, which can only represent "less than" or "equal to."

∴ The formula for the given statement is 2m - 5/4 < 7/8.

The length of the interval AB is 7.21 units.

Given,

From the graph we can have the triangle ABC.

Length of side AC = 6 - 2 = 4 units

Length of side BC = 7 - 1 = 6 units

We have to find the length of AB.

By using Pythagorean theorem we can determine the length of AB.

Hypotenuse² = Altitude² + Base²

AB² = AC² + BC²

AB² = 4² + 6²

AB² = 16 + 36

AB² = 52

AB = [tex]\sqrt{52}[/tex] = 7.21

That is, the length of the interval AB is 7.21 units.

From the given stem-and-leaf plot, we have that:

a) The maximum number of cups of coffee sold on a single day is of 78.

b) In 5 days, less than 60 cups were sold.

c) The average sales is of 65 cups of coffee a day.

What is the missing information?

The questions are missing, and they are given by the image at the end of the answer.

What is a stem-and-leaf plot?

The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:

4|5 = 45.

Considering the key in this problem, the measures(number of cups of coffee sold each day) are given as follows:

50, 52, 58, 59, 60, 63, 63, 65, 69, 69, 72, 75, 77, 78.

Hence:

a) The maximum number of cups of coffee sold on a single day is of 78.

b) In 5 days, less than 60 cups were sold.

The average of a data-set is given by the sum of all observations in the data-set divided by the number of observations, hence:

M = (50 + 52 + 58 + 59 + 60 + 63 + 63 + 65 + 69 + 69 + 72 + 75 + 77 + 78)/14 = 65.

The average sales is of 65 cups of coffee a day.

Step-by-step explanation:

Hello!

Let the amount of money earned be y, and the number of games they win be x.

For the Lady Falcons, the equation would be y = 2250 + 75x.

For the Lady Hornets, the equation would be y = 2750 + 25x.

The system would be [tex]\left \{ {{y= 2250 + 75x} \atop {y=2750 + 25x}} \right.[/tex].

_______________________________________________________

The question says not to solve, but we are going to solve it anyway for practice.

Solve the Systemy = 2250 + 75x
y = 2750 + 25x
y = 2250 + 75x
-(y = 2750 + 25x)

Given 2 apples have 1/5 grams of fat, we can set up an equation:

Bob built a large wooden storage box. The box was in the shape of a rectangular prism, as shown below. He covered all the sides of the box with special wallpaper that cost a total of $504. How much did the wallpaper cost per square foot?

Answers

The total cost of wallpaper is $4 per square foot as calculated from the surface area of the rectangular prism.

The total surface area is the total area of all the surfaces of an object. The surface area is calculated by the area of the surface in the form of the 2 dimensional representation.

Here the box is in the form of an rectangular prism , which means that the box is in the form of a cuboid.

From the figure we can see that the dimensions of the box are :

length = 6 feet

width = 5 feet

height = 3 feet

We know that the total surface area of a rectangular prism is given by:

2×(length × width + width  ×height + height × length)

or, 2 × (6×5 + 5×3 + 3×6)

or, 126 ft²

Now the total cost for wallpaper is $504 .

Now to calculate the cost per square feet we will divide the total money by the total surface area.

∴Cost of the wallpaper per square foot=$(504÷ 126) per ft² = $4 per ft²

Hence the cost of the wallpaper is $ 4 per ft² .

Disclaimer: The figure of the prism is attached below.

Point F is on line segment EG. Given EG = 19 and EF = 15, determine the length FG.

Answers

The length of the line segment FG is equal to 4.

A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The Euclidean distance between two ends of a line segment determines its length.

Consider a line segment EG,

Let's say F is a point on the line segment.

Then,

Now we have,

The length of the line segment EG = 19 and the length of the line segment EF = 15.

Now,

EG = EF + FG

Subtracting EF from each side,

EG - EF = EF + FG - EF

FG = EG - EF

Substituting the values of EF and EG in the above equation,

FG = 19 - 15

FG = 4

A furniture store has a sale offering ​10% off of all furniture. If Amanda spent ​$360.99 on furniture before​ tax, what was the price of the furniture she purchased before the discount and before​ tax?

The equation is____. The cost of the furniture before the discount and tax is ​$____
​(Type an equation using x as the​ variable.)

Answers

The equation is [360.99 = (x - 0.10x)] and the cost of the furniture before the discount and tax is ​$ 401.1

As per the question statement, a furniture store has a sale offering ​10% discount on all furniture, and Amanda spent ​$360.99 on furniture before​ tax.

We are required to determine the equation using which, we can calculate the price of the furniture before the discount and tax, and also the price of the furniture before the discount and tax.

So, let us assume that the original cost of the furniture (before the discount and tax) is "x".

As per the question statement, Amanda spent ​$360.99 on furniture before​ tax, but with the discount applied over the original cost of the furniture, i.e.,

We can form a linear equation with the assumed variable "x" and the condition mentioned above, and solve the equation to obtain our required answer.

360.99= [x-(10/100*x)}

0r 360.99=(x-x/10)

or 360.99=(10x-x)/10

or 360.99=9x/10

x=401.1

Hence, the equation is [360.99 = (x - 0.10x)] and the cost of the furniture before the discount and tax is ​$ 401.1
