To find out how long it takes for a light bulb to consume 9450 watt-hours, when it uses 1800 watt-hours per day, divide 9450 watt-hours by 1800 watt-hours per day, which equals 5.25 days.
Explanation:The question involves calculating how long it takes for a light bulb to consume a certain amount of energy (9450 watt-hours) given its daily consumption rate (1800 watt-hours per day).
To find the duration, you simply divide the total energy by the daily consumption rate:
Total energy to be consumed = 9450 watt-hours
Daily energy consumption = 1800 watt-hours per day
Duration = Total energy ÷ Daily energy consumption
Duration = 9450 watt-hours ÷ 1800 watt-hours/day = 5.25 days
Therefore, it will take 5.25 days for the light bulb to consume 9450 watt-hours of energy.

The two numbers are 53/6 and -55/6.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Let x and y be the two numbers.
We have sum of them is -1/3
x + y = -1/3 [Equation 1]
The difference of two numbers is 18.
x - y = 18 [Equation 2]
Adding equations 1 and 2,
x + y + x - y = -1/3 + 18
2x = 18 - [tex]\frac{1}{3}[/tex]
2x = 53/3
x = 53/6
Substituting the value in equation 1,
53/6 + y = -1/3
y = -1/3 - 53/6
= -55/6
Hence the numbers are 53/6 and -55/6.

Find the dimensions of the rectangular box with largest volume if the total surface area is given as 16 cm2. (let x, y, and z be the dimensions of the rectangular box.) (x, y, z) =
Final answer:
Finding the exact dimensions of a rectangular box with the largest volume from a given surface area of 16 cm2 requires additional constraints. For illustrative purposes, in the case of a cube with equal sides, the side length can be found using the formula for surface area, showing how such a problem might be approached.
Explanation:
To find the dimensions of a rectangular box with the largest volume given a total surface area of 16 cm2, we can use the method of Lagrange multipliers or understand the principle that for a given surface area, the box which is closest to a cube will have the largest volume. However, without additional constraints, like a relation between the dimensions (x, y, z), solving for specific x, y, z values directly from just the surface area constraint alone leads to an infinite number of solutions. For simplicity, we'll consider a problem where symmetry is involved, as in the case of a cube, to illustrate how one might approach it.
Surface area of a rectangular box is given by 2(xy + xz + yz) = 16 cm2. To simplify and directly answer based on the data given would require additional constraints, such as assuming all sides are equal. For a cube, with all sides equal (let’s call each side 'a'), the surface area would be 6a^2. Solving 6a^2 = 16 gives a = sqrt(16/6) ≈ 1.633. This illustrates a scenario under specific conditions but doesn't directly solve the original question without additional constraints.

The sum of a number and its square is 2. Find the number(s).
The number 'x' that satisfies the condition of the sum of a number and its square equaling 2 are 1 and -2. This is determined by setting up a quadratic equation and solving for 'x'.
Explanation:To solve this problem, let's start by defining the unknown number we are looking for as 'x'. According to the problem, the sum of a number (x) and its square (x²) equals 2. As a mathematical equation, this would be written as x + x² = 2.
Once this equation is set up, we can solve for x. However, the equation is quadratic, which means it may have two solutions. Anyway, the equation can be rearranged into the standard quadratic format as x² + x - 2 = 0. It can be factored into (x - 1)(x + 2) = 0. This gives us two potential solutions for x: x = 1 and x = -2.
To verify if these solutions are valid, we can substitute them back into the original equation: 1 + 1² = 2 is true, and -2 + (-2)² = 2 is also true. Thus, both of these numbers, 1 and -2, are solutions to the original problem.

Nadiya determines that there are no fractions equivalent to 2/10 with a denominator greater than 10, but less than 20, that have a whole number numerator and denominator. Is Nadiya correct?
Yes, Nadiya is correct. By multiplying the numerator and denominator by 2, the first fraction equivalent to 2/10 is 4/20.
Yes, Nadiya is correct. By multiplying the whole fraction by any whole number, each equivalent fraction will continue to have a denominator of 10.
No, Nadiya is incorrect. She could multiply both the numerator and denominator of the unit fraction equivalent to 2/10 by 3 and arrive at the equivalent fraction 3/15.
No, Nadiya is incorrect. She could add any number between 1 and 8 to the numerator and denominator and arrive at an equivalent fraction with a denominator greater than 10 but less than 20.
No, Nadiya is incorrect. There is a fraction equivalent to 2/10 with a denominator greater than 10 but less than 20, which is 3/15.
Explanation:No, Nadiya is incorrect. She could multiply both the numerator and denominator of the unit fraction equivalent to 2/10 by 3 and arrive at the equivalent fraction 3/15.
When multiplying a fraction by a whole number, both the numerator and the denominator are multiplied by that number. By multiplying 2/10 by 3, we get (2 * 3)/(10 * 3) = 6/30, which can be simplified to 3/15.
Therefore, there is a fraction equivalent to 2/10 with a denominator greater than 10 but less than 20, and it is 3/15.

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity is called volume. The volume of the given figure is 233 in³.
What is Volume?The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity is called volume.
The given figure can be divided into two parts. The first figure 'A' is a cuboid, while the second figure 'B' is a cube. As shown below.
Now, the volume of the figure can be calculated by adding the volume of the cuboid A and the volume of the cube B.
The volume of Cuboid A can be written as,
[tex]\rm \text{Volume of cuboid} = Length \times Breadth \times Height[/tex]
[tex]= 12 \times 3 \times 3\\\\= 108\rm\ in^3[/tex]
The volume of Cube B can be written as,
[tex]\rm \text{Volume of Cube} = (Side)^3[/tex]
[tex]= 5^3\\\\= 125\rm\ in^3[/tex]
Further, the volume of the figure can be written as,
The volume of the figure = Volume of the cuboid + Volume of the Cube
= 108 + 125 = 233 in³
Hence, the volume of the given figure is 233 in³.

Answer:
8 in 15 in 17 in.--- form a right angled triangle.
4 in 15 in 17 in.---- do not form a right angled triangle.
Step-by-step explanation:
We know that according to the PYTHAGOREAN THEOREM of right triangles we have:
[tex]c^2=a^2+b^2[/tex]
where c is the hypotenuse or the largest side of a triangle and a and b are other two legs of a right triangle,.
1)
8 in 15 in 17 in.
[tex]17^2=15^2+8^2\\\\289=225+64\\\\289=289[/tex]
Hence, the given measure of sides form a side of a right angled triangle.
2)
4 in 15 in 17 in.
Since,
[tex]17^2\neq 15^2+4^2[/tex]
Hence, the given measure of sides do not form a side of a right angled triangle.
