Answer:

A. $440

Step-by-step explanation:

What is important to know here is how many weeks does the year have. A regular year has 52 weeks.

To calculate this we must first multiply the hours worked, the value of these and finally the weeks the year have.

7*20*52= 7280.

To the result of that, you must deduct the savings Anastasia had wich are $2000.

7280-2000= 5280.

$5280 is the amount of money spent on expenses for the entire year. If you divide that between the number of months a year has (12) you will reach the answer to the question.

5280/12= 440.

I hope this answer helps you.

A set of kitchen containers can be stacked to save space. The height of the stack is given by the expression LaTeX: 1.5c+7.61.5

Nuetrik [128]

Answer:

Part A

The height of the stack made of 8 containers is 19.6 cm

Part B

When the tower is 40.6 cm tall, the number of containers in the set are 22 containers

Part C

(Disagree) The height of a single container is 9.1

Step-by-step explanation:

The question relates to containers, stacked one inside the other such that the height increases by only the wider top edge of the containers

The given expression that gives the height of the stack is presented as follows;

1.5·c + 7.6

Where;

c = The number of containers in the stack

Part A

When there are 8 containers, we have;

h(8) = 1.5 × 8 + 7.6 = 19.6

The height of the stack made of 8 containers, h(8) = 19.6 cm

Part B

When the tower (height of the stack set) is 40.6 cm tall, we have;

h(c) = 1.5·c + 7.6 = 40.6

∴ The number of containers, c = (40.6 - 7.6)/1.5 = 22

When the tower is 40.6 cm tall, the number of containers in the set, c = 22 containers

Part C

Given that the height stack increases only by the thickness of the wider rim of each added container, we have;

The expression for the height of the stack , 1.5·c + 7.6, is the expression for a straight line equation, m·x + c

The thickness of each rim = The slope, of the line, m = The increase in height with number of containers = 1.5

The number of containers (The independent variable, x) = The number of stacked rims = c

The minimum height = The height of a single container = 1.5 × 1 + 7.6 = 9.1

Therefore, the height of a single container = 9.1 not 7.6

What is the value of |-6|—|6|-(-6)? The solution is

Rzqust [24]

Answer:

Step-by-step explanation:

|-6| = 6

|6| = 6

- -6 = +6

so, we have
