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.

Which of the following describes the solution set for |-4+5x|=16? A{4}. B{4, -4}. C {4, -12/5}. D{-12/5}
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 = -16Solving the first equation gives us:
5x = 16 + 45x = 20x = 4Solving the second equation gives us:
5x = 16 - 45x = 12x = 12/5x = 2.4However, 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 = -12/5Therefore, the correct solution set is {4, -12/5}, which corresponds to option C.
What is the solution of 4+sqrt5x+66=x+10
The solution for 4+√5x+66=x+10 is x=3 (option 2)

in the number 2.348 the underlined digit is 3 what does it round to if its in the tenths place
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.
Answer: 2.3

the game room of the youth center needs carpet. the room measures 3 feet by 2 feet on the blueprint. if the scale on the blueprint is 1 foot to 5 yards, what is the actual area of the game room?
The actual area of the game room is 150 square yards.
Explanation:To find the actual area of the game room, we need to convert the dimensions on the blueprint to actual measurements. The scale on the blueprint is 1 foot to 5 yards, so we can convert the length and width of the room by multiplying by 5. The room measures 3 feet by 2 feet on the blueprint, so the actual dimensions are 3 feet x 5 yards and 2 feet x 5 yards. Thus, the actual area of the game room is (3 feet x 5 yards) x (2 feet x 5 yards), which simplifies to 15 yards x 10 yards or 150 square yards.

Keiko has a total of $ 5200 comma which she has invested in two accounts. The larger account is $ 900 greater than the smaller account. (Let x be the amount of money in the larger account and y be the amount of money in the smaller account.)
Keiko has a total of $5200
x is the amount of money in larger account
y is the amount of money in smaller account
x - y = $900
and x + y = $5200
This creates two simultaneous equations:
x - y = $900 ... (i)
x + y = $5200 ... (ii)
Adding (i) and (ii) :
2x = $6100 , x = $3050
y = x - $900 = $3050 - $900 = $2150
The amount of money in larger account (x) = $3050
The amount of money in smaller account (y) = $2150
To solve the problem, we set up and solved a system of equations using the given information. We find that Keiko has invested $2150 in the smaller account and $3050 in the larger account.
Explanation:Keiko has $5200 that she invested in two accounts. We're told the larger account is $900 more than the smaller one. Since we let x represent the amount of money in the larger account and y represent the amount of money in the smaller account, we can establish the following system of equations:
x + y = $5200 x = y + $900
Substituting the second equation into the first, we get:
(y + $900) + y = $5200
Solving for y from this equation, we obtain y = $2150, representing the smaller account. Substituting y into the original second equation, we find x = $3050, which is the larger account. Hence Keiko has $2150 in the smaller account and $3050 in the larger account.

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]
