How Can You Find The Area Of Diameter

Answers

Answer 1
HEY THERE !!

As we know that the area of a circle (A)= πr^2

But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}

Here diameter is 10.5 inches.

A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}

So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.

You and your mom enter a drawing with 3 different prizes. A total of 8 people entered the drawing, and prizes are awarded randomly.There are 336 ways to award the prizes.What is the probability that you win first prize and your mom wins second prize?
A. 8/336
B. 1/8
C. 6/336
D. 1/336

Answers

It's actually C. 6/336

Answer: [tex]\frac{6}{336}[/tex]

Step-by-step explanation:

Given: The Number of different prizes = 3

The number of people entered the drawing room = 8

The number of ways to select for 3 prizes, such that  you win first prize and your mom wins second prize = You × Mom × Rest of people

[tex]1\times1\times(8-2)=1\times6=6[/tex]

The total number of ways to award the prizes = 336

Therefore, the probability that you win first prize and your mom wins second prize=[tex]\frac{6}{336}[/tex]

What is the pattern rule for this pattern 5-8-14-23-55?

Answers

It’s +3 and then multiply 3 each time. I can’t really explain it, but here’s an example
1, 4, 10, 19
1 + 3 = 4,
3x2=6
4 + 6 = 10
etc etc

Final answer:

The sequence 5-8-14-23-55 does not follow a clear linear or geometric pattern rule based on the differences between its terms. A simple pattern is not evident, and more context is required to determine if there's a complex rule or an error with the given numbers.

Explanation:

The sequence provided, 5-8-14-23-55, does not have a clear linear or geometric progression that is immediately evident. To determine the pattern rule, we need to look at the differences between successive terms:

8 - 5 = 3

14 - 8 = 6

23 - 14 = 9

55 - 23 = 32

The differences between the first few terms are incremental by 3, but the last increment does not follow this progression. Therefore, there is no single common pattern rule applicable to the entire sequence given. If more context or additional numbers in the sequence are provided, it may be possible to discern a more complex rule or recognize if the last term is an error.

in the number 2.348 the underlined digit is 3 what does it round to if its in the tenths place

Answers

It rounds down to 0 because 4 or lower rounds down and 5 or higher rounds up

I assume the underlined digit tells you to round off to that place. In this case, the 3 is in the tenths place, so you need to round off 2.348 to the nearest tenth.

2.348

The 3 is in the tenths place. If you are asked to round off to the nearest tenth, then first, drop the digits to the right of the 3. Now you have 2.3, but we need to look at the next digit in the original number. The original number was 2.348, with a 4 to the right of the 3. Since 4 is less than 5, you just keep the rounded number as 2.3.

Mandana is ordering new tile for her kitchen floor. The area of the floor is 119.9 square feet, and she wants to order between 15% and 20% extra of the materials. Which of the following is a reasonable amount of tile for Mandana to order?
A.
134 square feet
B.
140 square feet
C.
137 square feet
D.
145 square feet

Answers

Final answer:

To find a reasonable amount of tile for Mandana to order, we need to calculate 15% and 20% of the area of her kitchen floor and add that to the original area. Therefore, options B and D can be considered as reasonable amounts of tile for Mandana to order.

Explanation:

To find a reasonable amount of tile for Mandana to order, we need to calculate 15% and 20% of the area of her kitchen floor and add that to the original area.

15% of 119.9 square feet is 0.15 * 119.9 = 17.985 (approximately 18 square feet).

20% of 119.9 square feet is 0.20 * 119.9 = 23.98 (approximately 24 square feet).

Adding the additional tile to the original area, the reasonable amounts of tile for Mandana to order would be:

A. 119.9 + 18 = 137.9 square feet (approximately 138 square feet)B. 119.9 + 24 = 143.9 square feet (approximately 144 square feet)C. 119.9 + 18 = 137.9 square feet (approximately 138 square feet)D. 119.9 + 24 = 143.9 square feet (approximately 144 square feet)

Therefore, both options B and D, which are 140 and 145 square feet respectively, can be considered as reasonable amounts of tile for Mandana to order.

Final answer:

To find a reasonable amount of tile for Mandana to order, calculate the range of 15% to 20% extra of the materials by multiplying the area of the floor by each percentage. Add the extra amount to the area of the floor to get the reasonable amount of tile to order.

Explanation:

To find a reasonable amount of tile for Mandana to order, we need to calculate the range of 15% to 20% extra of the materials she needs. First, we find the extra amount by multiplying the area of the floor by each percentage. The extra amount ranges from 17.985 to 23.98 square feet. Finally, we add the extra amount to the area of the floor to get the reasonable amount of tile to order, which ranges from 137.985 to 143.98 square feet. Therefore, option C (137 square feet) is a reasonable amount of tile for Mandana to order.

e) use the equation from part (c) to estimate the profit for Buffalo wild wings in 2017. Do you think that it is an accurate estimate. Explain.

Answers

a) See attached diagram.

b) The slope can be obtained by the formula:

[tex]m_i=\dfrac{y_{i+1}-y_i}{x_{i+1}-x_i}.[/tex]

Now

[tex]m_1=\dfrac{24.4-19.7}{8-7}=4.7;[/tex][tex]m_2=\dfrac{30.7-24.4}{9-8}=6.3;[/tex][tex]m_3=\dfrac{38.4-30.7}{10-9}=7.7;[/tex][tex]m_4=\dfrac{50.4-38.4}{11-10}=12;[/tex][tex]m_5=\dfrac{57.3-50.4}{12-11}=6.9;[/tex][tex]m_6=\dfrac{71.6-57.3}{13-12}=14.3;[/tex]

Answers

Answer:

The equation will be:   [tex]y=4x[/tex]

Step-by-step explanation:

Side lengths[tex](x)[/tex] ⇒    4.5       8.5        10.25       13.75

Perimeter [tex](y)[/tex]    ⇒     18         34            41            55

First we will pick any two ordered pairs in form of point like [tex](x,y)[/tex]. So, here [tex](x_{1}, y_{1})= (4.5, 18)[/tex] and [tex](x_{2}, y_{2})= (8.5, 34)[/tex]

Now, the slope will be:  [tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}= \frac{34-18}{8.5-4.5}=\frac{16}{4}=4[/tex]

So, the equation using the point-slope form will be..............

[tex]y-y_{1}=m(x-x_{1})\\ \\ y-18=4(x-4.5)\\ \\ y-18=4x-18\\ \\ y=4x[/tex]

Thus, the equation that represents the relationship between the side length[tex](x)[/tex] and the perimeter[tex](y)[/tex] will be:  [tex]y=4x[/tex]

Which of the following describes the solution set for |-4+5x|=16? A{4}. B{4, -4}. C {4, -12/5}. D{-12/5}

Answers

Answer:

C:  {4, -12/5}

Step-by-step explanation:

Let's actually solve |-4+5x|=16:  Divide all 3 terms by 5.  Then:  |-4/5 + x| = 16/5.

If we were to graph this, the center (on a number line) would be at -4/5.  Now if we add 16/5 to -4/5, we get 12/5, the larger solution; if we subtract 16/5 from -4/5, we get -20/5, the smaller solution, equivalent to -4.  Correct answer choice is C.

This corresponds to option C.

The solution set for the absolute value equation |-4+5x|=16 can be found by considering both the positive and negative scenarios since an absolute value represents the distance a number is from zero on the number line, without regards to direction (positive or negative).

To find the solution set, we need to split the absolute value equation into two possible linear equations:

4 - 5x = 16-4 + 5x = -16

Solving the first equation gives us:

5x = 16 + 45x = 20x = 4

Solving the second equation gives us:

5x = 16 - 45x = 12x = 12/5x = 2.4

However, x = 2.4 does not make sense in the context of our original problem, because we are looking for the negative solution when we consider the equation -4 + 5x = -16. The correct step is:

5x = -16 + 45x = -12x = -12/5

Therefore, the correct solution set is {4, -12/5}, which corresponds to option C.
