Answer:

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.

Is 80 a multiple of 4?

Answers

Generally, you can tell if something is a multiple of 4 if it is a multiple of the last two digits, but that works in larger numbers (for example, 2304, you know is a multiple of 4 because the 04 is.)

But, yes it is.

80/4=20

yes here look.....

Solve the Equation!!

Z - 2/3 = 1/8

Answers

$z- (2)/(3) = (1)/(8) \n\n z = (1)/(8) + (2)/(3) \n\nz = (3)/(24) + (16)/(24)\n\nz = (3+16)/(24) \n\nz= (19)/(24)$

The value of Z in the equation given is 19/24.

Given is an equation, Z - 2/3 = 1/8, we need to solve for Z,

To solve the equation Z - 2/3 = 1/8, follow these steps:

To clear the fraction, we can multiply every term in the equation by the least common multiple (LCM) of the denominators, which in this case is 24.

This step eliminates the fractions from the equation.

Multiplying each term by 24:

24(Z) - 24(2/3) = 24(1/8)

Simplifying:

24Z - 16 = 3

To isolate the variable Z, we need to get rid of the constant term (-16) by adding 16 to both sides of the equation.

24Z - 16 + 16 = 3 + 16

Simplifying:

24Z = 19

To solve for Z, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 24.

24Z/24 = 19/24

Simplifying:

Z = 19/24

Therefore, the solution to the equation Z - 2/3 = 1/8 is Z = 19/24.
