Answer:
There is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.
Step-by-step explanation:
First, we need to calculate the volume of each balloon by considering the balloons as a sphere:
Where:
r: is the radius = 0.4 meters
Knowing that 1 m³ of helium is able to lift about 1 kg, that Mr. Schordine weights 84 kg, and that each ballon has 0.27 m³ of helium, the number of balloons needed are:
Therefore, there is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.
I hope it helps you!
- Simplify :- 1 + - w² + 9w.
Quadratic polynomial can be factored using the transformation , where are the solutions of the quadratic equation .
All equations of the form can be solved using the quadratic formula: . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
Square 9.
Multiply -4 times -1.
Add 81 to 4.
Multiply 2 times -1.
Now solve the equation when ± is plus. Add -9 to .
Divide -9+ by -2.
Now solve the equation when ± is minus. Subtract from -9.
Divide by -2.
Factor the original expression using . Substitute for and for .
<h3>NOTE :-</h3>
Well, in the picture you inserted it says that it's 8th grade mathematics. So, I'm not sure if you have learned simplification with the help of biquadratic formula. So, if you want the answer simplified only according to like terms then your answer will be ⇨
This cannot be further simplified as there are no more like terms (you can use the biquadratic formula if you've learned it.)
You would add up the percentages first, which would bring everything up to 35%. You would then take the original cost of the item, which is $30 and multiple it by the 35%.
The equation would look like...
30 x .35 =
This will give you $10.50, which isn't the final answer.
You would then subtract 10.50 from the $30 that was asked for at the beginning by the retailer.
Your final answer is $19.50. :) Which isn't a bad deal if I say so myself.
The polynomial function of lowest degree with lead coefficient 1 and roots 1 and 1 + i is f(x) = x3 - 3x2 + 4x - 2.
