representing the number of chocolates remaining in the box t days after Zoe's
birthday.

Answers

Answer:

Stay safe

The expression for the number of chocolates remaining will be c = 24 - 4t.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that, Zoe was given a box of assorted chocolates for her birthday. Each night, she to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there were 12 chocolates remaining in the box.

Let the number of days be represented by t, and the number of chocolates will be C.

The total number of chocolates will be calculated as,

Total = 3 x 4 + remaining chocolates = 12

Total = 3 x 4 + 12

Total = 12

The expression will be written as,

C = 24 - 4t

Therefore, the expression for the number of chocolates remaining will be c = 24 - 4t.

Answer:

10%

Step-by-step explanation:

We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.

This means the total number of single digits that could possibly be a winning one is 10.

Since we are told that only 1 can be picked, thus;

Probability of winning is; 1/10 = 0.1 or 10%

The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%

Answers

Answer:

C. 20%

Step-by-step explanation:

50*2=100

40*2=80

100-80=20

A percentage is a number or ratio that represents a fraction of 100. 

The percentage decrease in the cost of the pair of pants is 20%.

What is a percentage?

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

10% = 10/100 = 1/10

25% = 25/100 = 1/4

20% = 20/100 = 1/5

We have,

The initial cost of pair of pants = $50

The final cost of pair of pants after reduced = $40

The percentage decrease in the cost of pair of pants:

= [( Initial cost - Final cost ) / Initial cost] x 100

= [(50 - 40) / 50] x 100

= (10/50) x 100

= 20%

Thus,

The percentage decrease in the cost of the pair of pants is 20%.
