Answer 1

Answer: Adding and subtracting amonomial requires having the same variables. No matter how big or small theircoefficient is, if their variables do not match, they cannot be added or subtracted.The crucial part in adding or subtracting monomials is their sign. If the signsare the same, retain the sign. If the signs are different, subtract and keepthe sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
3x2y + 3x3 (cannot be added)

Given the following scenario, decide if it is a permutation or combination, and then calculate the possibilities. Papa John’s pizza has 17 different toppings to choose from. In how many ways can you make a three topping pizza?

Answers

It is a combination because the order in which the toppings are used does not change the result.

The formula of combination is C 17,3 = 17!/(3!14!) = 17x16x15/(3x2) = 17x8x5 = 680 different ways.

4 brothers share 3 pizzas equally.
How much of a pizza does each brother get ?

Answers

4 brothers /3 pizzas = 3/4 each

4 x 3/4 = 12/4
12/4 = 3 pizzas

3/4. No matter how many pizzas there are, if we divided each pizza to 4 slices, each one gets one slice from each pizza, that is 1/4 of a pizza for each brother. Since there are 3 slices of pizza, simply multiply 3*1/4=3/4.

How do you " find, to the nearest tenth of an inch, the diagonal of a square whose perimeter is 28 inches ?"

Answers

Well if the perimeter is 28 inches, each side of the square is 7 inches. 28/4 = 7 because all sides of a square are the same.

If we split the square in half to create 2 triangles we can find the length of the diagonal. The two sides are the bases of 7 inches.

Use the Pythagorean theorem to solve for the hypotenuse or the diagonal.

7^2 + 7^2 = diagonal ^ 2

Therefore, the diagonal equals 9.9 inches.

A scientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour. At 1 hour, the bacteria had grown to 880 cells, and at 2 hours, had grown to 3,520 cells. Which function can be used to represent the relationship between the number of bacteria cells, y, and the time in hours, x?

Answers

Answer: Hello!

we know that in the first hour, we had 880 cells, and in the second hour we have 3520 cells. The first step is see how much the population changed in this one hour, this can be done by looking into the quotient:

3520/880 = 4

then the population of cells cuatriplied in one hour, and is safe to asume that every hour that pases, the population will catriplied again.

so if the populationat hour 1 is: 880

at hour 2 is: 4*880

at hour 3 is = 4*4*880 and so on.

This can be described with an exponential function as follows

$P(t) = 880*4^(x-1)$
