How much power is needed to get up the stairs, if I can do this with 30 Joules of work in 3 seconds?
Answer:
10 Joules/second
Step-by-step explanation:
To find the power needed to get up the stairs, we need to divide the amount of work done (30 Joules) by the time it took to do the work (3 seconds):
Power = Work / Time
Power = 30 Joules / 3 seconds
Power = 10 Joules/second
Therefore, it takes 10 Joules/second of power to get up the stairs.

Answer: a is about 7.416, rounding to two significant digits, 7.4, to one significant digit, 7.
Step-by-step explanation:
We will use the Pythagorean Theorem.
a²+b²=c²
c² is the longest side, so 8cm.
lets make the bottom side b², so 3cm
We are trying to find h, so let's make that a².
Applying the Theorem:
a²+3²=8²
--- a² + 9 = 64
subtract 9 from both sides.
-- a² = 55
Take the square root of both sides
a is about 7.416, rounding to two significant digits, 7.4, to one significant digit, 7.
Answer:
22.249 cm^2 (THIS IS ROUNDED)
Step-by-step explanation:
to find the area we first need to find h using Pythagorean theorem
a^2+b^2=c^2
We need to isolate a^2 on one side
a^2+b^2=c^2
-b^2. -b^2
a^2=c^2-b^2
a^2=8^2-3^2
a^2=64-9
a^2=55

How and his friends bought stickers for $1.25 each and will mark them up 180%. What will they sell the tickets for?
Answer:$2.25x
Step-by-step explanation:
Lets use X to denote the amount of stickers How and his friends bought. so he buys them at 1.25x. An easy trick when doing percentages of a number is thinking of the percent as a fraction. So instead of 180, think of 180/100. Think of 1.25 as 125/100
multiply 180/100 by 125/100
you get 22500/10000 which equals 2.25

For the given equation, we can prove that with many ways. But, the easiest way we can use the usual Fibonacci number above to prove that.
We assume n = 3 so the number is 2.
[tex]f_{n+1}f_{n-1}-f^2_{n} = (-1)^n[/tex]
(3)(1) - (2^2) = (-1)^2
3 - 4 = -1
-1 = -1
We also can assume n = 5 so the number is 5.
[tex]f_{n+1}f_{n-1}-f^2_{n} = (-1)^n[/tex]
(8)(3)-(5^2) = (-1)^5

The formula in Ohm's Law is E = IR, where E represents voltage measured in volts, I represents current measured in amperes, and R represents resistance measure in ohms. Solve for R.
To solve for R in Ohm's Law, you can rearrange the formula to isolate R on one side of the equation. To solve for R, you can divide both sides of the equation by I:
R = E/I
This rearranged formula shows that the resistance R is equal to the voltage E divided by the current I. For example, if you have a voltage of 10 volts and a current of 2 amperes, the resistance would be 5 ohms:
R = 10 volts / 2 amperes = 5 ohms
Let's prep ourselves before attempting to answer the question. What do we need to know?
We'll need to know a couple of basic concepts before we tackle the problem. Namely, we'll need these ones:
Equality PropertiesWhat are equality properties? These are the equality properties:
Multiplication Property of EqualityDivision Property of EqualityAddition Property of EqualitySubtraction Property of EqualityDefineFrom the problem, we are given Ohm's Law, which is E = IR. The problem states that it wants to solve this equation for R.
WorkIn order to solve Ohm's Law for R, we can use the Division Property of Equality. What does this property state? It states that if you divide something (number, variable, etc.) on one side, you must do the same for the other.
Now, let's apply this property to find our answer. We divide by I on both sides to isolate R:
[tex]\displaystyle\begin{aligned}E & = IR \\IR & = E \\\frac{IR}{I} & = \frac{E}{I} \\R & = \boxed{ \frac{E}{I} } \\\end{aligned}[/tex]

a brick staircase has a total of number of 12 steps. the bottom step requires 100 bricks.A total of 246 bricks are required to build the staircase.
The total number of steps in the brick staircase is 12. The bottom step requires 100 bricks. Each successive step requires 4 less bricks than the prior one. Therefore, the number of bricks required to build the staircase can be calculated as follows:
The first step requires 100 bricks.
The second step requires 96 bricks (100 - 4 = 96).
The third step requires 92 bricks (96 - 4 = 92).
This pattern continues until all 12 steps are accounted for.
Adding the number of bricks required for each step gives a total of 246 bricks required to build the entire staircase.

Describe the Vertex Form of a Quadratic
equation in words.
The vertex form of a quadratic equation is a standard form of a quadratic equation that is written in the form:
y = a(x-h)^2 + k
where a, h, and k are constants. This form is called the vertex form because it represents the graph of the quadratic equation as a parabola, with the vertex of the parabola located at the point (h,k).
The vertex form of a quadratic equation is useful because it allows us to easily identify the vertex of the parabola and the direction in which the parabola opens. If a is positive, the parabola opens upwards and the vertex is the minimum point of the parabola. If a is negative, the parabola opens downwards and the vertex is the maximum point of the parabola.
Overall, the vertex form of a quadratic equation is a standard form that represents the graph of a quadratic equation as a parabola with a specific vertex location. It is useful for identifying the characteristics of the graph and for solving problems involving quadratic equations.

how much water should we add to 20kg of sea water to change its concentration from 2% to 3%
Answer: 10 kg
Step-by-step explanation:
3% = 0.03
First, take 20 times 0.03 = 0.6kg of salt
We know that the 2% solution of seawater
So, we take 100 times 0.6, then divide by 2 = 30kg
Then take 30 - 20 = 10kg
So, to make a solution from 3% to 2%, we have to add 10 kg of water with a 20 kg solution.
