Answer 1

Answer:

8.1x^4 x 0.2 = 1.62x^4

Step-by-step explanation:

Answer 2

The estimated multiplication of 8.1 and 4.2 is close to 32.

What is a decimal?

A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.

Estimations are essential when we don't have a tool to calculate the exact value of something.

Given A multiplication of two decimal numbers 8.1 and 4.2.

Now 8.1 can be estimated as 8 and 4.2 can be estimated as 4 and we know 8 times 4 is 32 so, the multiplication of 8.1 and 4.2 is close to 32.

2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.

12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.

1.2 = k

Next write the equation using this k and the h & n.

h = 1.2*n

Now we want to find the height if we have 24 books so plug 24 in for n.

h = 1.2 * 24

h = 28.8 inches

a. Explain why this is not a good method.
b. Suggest a better method.

Answers

A. The method is not a good method because the student that walks through the door first is probably the student who always walks through the door first. This makes the choosing not random and makes it a biased choice.

B. The teacher should pulls sticks with the students names on it, or use a random name generator.

Answer:

It is not a good method because the first person to walk through the door should be rewarded for being on time and it is pretty much  that the first person to walk in is always the first to walk in  

They should have a  volunteer and make them do it step by step for other kids to see or if someone is late  make them do it
