The two third of the given number,
⇒ (2/3)x120 = 80
The given number is,
120
We have to find its two third:
To find this,
First multiply this number wit 2 then,
2x120 =240
Then divide the number by 3
240/3 = 80
Thus two third of the given number can be written as,
(2/3)x120
= (2x120)/3
= 240/3
= 80
Hence,
⇒ (2/3)x120 = 80

We will have to divide the length the coach wants you to swim by the length of your pool to find how many laps you must swim. However, we need to first convert 3 km to meters by multiplying by 1000 (because 1 km = 1000 m).
3 * 1000 = 3000 m
Now we can divide.
You will need to swim 120 laps (not a realistic number).

Final answer:
You can solve the quadratic equation using the quadratic formula. For the system of three equations, use basic algebra according to the given condition. The equation involving sum of products can be solved by performing individual multiplications and then calculating the sum.
Explanation:
To help you understand and solve these mathematical equations, let's break them down. For the
quadratic equation
4.90t² + 20t +c = 0, you can use the quadratic formula to find the values of t. It's important to note here that the quadratic formula is [-b ± sqrt(b² - 4ac)] / (2a).
Also, given the system of three equations and three unknowns (Qd, Qs, and P), you can solve these using basic algebra. With Qd = Qs you can set the demand and supply equations equal to each other: 16 - 2P = 2 + 5P. You can then rearrange and solve for P.
Lastly, you have an equation where calculation of the sum of the products is involved: 1(.35) + 2(.20) + 3(.15) + 4(.15) + 5(.10) + 6(.05) = 2.6 years. This means that each number is multiplied by the corresponding percentage and then all results are added up.
