Note that you are estimating.

Estimate each to the nearest whole number

Note that when rounding, look at the digit to the right of the one you want to round to. If the digit is 5 or greater round up, if 4 and lower, round down.

1.537 rounded to the nearest whole number is 2

2 x 242 = 484

484 is your answer

hope this helps

Answer: The answer to this question is 38 in.

Step-by-step explanation: All we have to do here is to add all the sides and here's the formula P=s+s+s where s stands for side. We substitute in the values P= 14+8=16 and the result is P= 38 in. Hope this helps!

9,990 first digit is like 1, then 10, then 100, then 1000 so the fourth digit being 1 goes to 0 when rounding

When rounding to the nearest thousand, you look at the following number to know if you go up or stay. In the case of 9,991:

9,991     If the 2nd largest digit is ≥ 5, then round up.

10,000

Therefore, you would round 9.991 to 10,000.

Hope this helps! :)

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]

Solution

The 1st term = -3

15th term = 53

15th term = a + d(n-1)

53 = -3 + d(15- 1)                       [Here n = 15)

53 + 3 = d(14)

14d = 56

d = 4

The common difference is 4.

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

The greatest increases were from 2012 till 2013 years and the least increases were from 2007 till 2008 years.

c) Using graphing calculator, the equation of the line (black line in the diagram) is

[tex]y\approx 0.71x^2-5.58x+23.76.[/tex]

d) Since the slopes are different, this line is not straight. From the given data you can predict that the "best fit" is quadratic function.

e) In 2017, find

[tex]y(17)\approx 0.71\cdot 17^2-5.58\cdot 17+23.76\approx 134.09[/tex]

Answer:

Step-by-step explanation:

To find the two numbers, we can assign a variable and set up an equation based on the given information. By solving the equation algebraically, we can determine that the two numbers are 52 and 73.

To solve this problem, we can assign a variable to one of the numbers.

Let's say the first number is x.

Then, the second number would be 125 - x, since the sum of two numbers is 125.

Next, we can set up an equation with the given information: 5x - 3(125-x) = 41.

Simplifying this equation, we get 5x - 375 + 3x = 41.

Combining like terms, we have 8x - 375 = 41.

Adding 375 to both sides, we get 8x = 416. Finally, dividing both sides by 8, we find that x = 52. Therefore, the two numbers are 52 and 73 (125-52).

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.

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]

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.

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:

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.

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:

Solving the first equation gives us:

Solving the second equation gives us:

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:

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