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
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.

The sum of two numbers is 125. Five times one number minus three times the other is 41. Determine the numbers using one single variable
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.
Explanation: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).

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
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?
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.

round 9 991 to the nearest thousands
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! :)

Which product is negative?
−2⋅(−4)⋅8⋅(−1)
−7⋅(−3)⋅(−5)⋅(−8)
−3⋅(−4)⋅(−9)⋅0
6⋅(−2)⋅(−3)⋅1
When I had these kinds of problems, I'd count how many negatives there were. If there more or less negatives to positives, then it is negative. If there's the same amount of positives and negatives, then it's positive since they cancel out! The answer to this is A. (-2)(-4)(8)(-1)=-64.
In mathematics, the product −2⋅(−4)⋅8⋅(−1) is negative. This occurs because it has an odd number (three) of negative numbers being multiplied, leading to a negative product. The other options will give either a positive product or zero.
Explanation:In the realm of mathematics, when we multiply equal numbers of positive and negative values, we arrive at positive products. However, when we multiply an unequal number of positive and negative values, the product is negative. Let's apply this rule to the given products:
−2⋅(−4)⋅8⋅(−1): It contains three negative numbers, hence product will be negative.−7⋅(−3)⋅(−5)⋅(−8): It contains four negative numbers, hence product will be positive.−3⋅(−4)⋅(−9)⋅0: As one of the numbers is zero, the product will be zero.6⋅(−2)⋅(−3)⋅1: It has two negative numbers, so the product will be positive.
Among the provided choices, only the first product, −2⋅(−4)⋅8⋅(−1), will yield a negative product.

The table shows the side lengths and perimeters of four squares. Side Length (x) Perimeter (y) 4.5 18 8.5 34 10.25 41 13.75 55 Which equation represents the relationship between the side length, x, and the perimeter, y?
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]
Answer:
y=4x
