Which model represents 2.36 ÷ 4? A. Three groups of three tenths and four hundredths B. Three groups of five tenths and nine hundredths C. Four groups of three tenths and six hundredths D. Five groups of five tenths and nine hundredths

Answers

Answer:

Five groups of five tenths and nine hundredths

Step-by-step explanation:

Mathematically;

2.36 divided by 4 = 0.59

So we want to select from the options, the best representation of this

That will be

0.5 + 0.09

so our answer is 5 groups of five tents and nine hundredths

The model which represents 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths

We must perform the division 2.36 ÷ 4 first so that we have;

2.36 ÷ 4 = 0.59

The result, 0.59 can then be written in words as; Five tenths and 9 Hundredths.

Ultimately, the model. which represents the expression 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths.

25 of the bags have zips but no buttons.
45 of the bags have neither zips nor buttons.
How many bags have zips on them?

Answers

25 bags have zips on them

A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object. The total number of bags that have both zips and buttons is 49.

What is a set?

A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

Given that A company makes 140 bags. 21 of the bags have buttons but no zips. 25 of the bags have zips but no buttons. 45 of the bags have neither zips nor buttons.

Now, we can write the following things about the given condition,

Total number of bags, s = 140

Bags with Only zips, only Z = 25

Bags with only buttons, only B = 21

Bags with neither or them, Z'∩B' = 45

Now, the total number of bags that have both of them is,

Z∩B = s - only Z - only B - Z'∩B'

        = 140 - 25 - 21 - 45

        = 49

Hence, the total number of bags that have both zips and buttons is 49.
