Which equation can be used to determine y, the minimum amount of money a family must earn to meet the requirements of this budget for one year?

y = 3600 x 12

y = 3600 + 7

y = 3600 x 4

y = 360052

Answers

Answer:

[tex]y = 3600 * 12[/tex]

Step-by-step explanation:

Given: Breakdown of Monthly Budget

Required

Determine the equation that shows minimum earnings in a year

First, we need to get the sum of the given list of budgets:

[tex]Budget = 870 + 550 + 375 + 480 + 400+235+400 + 290[/tex]

[tex]Budget = 3600[/tex]

The are 12months in a a year; So, the yearly budget (y) is:

[tex]Yearly\ Budget = Monthly\ Budget * Duration[/tex]

[tex]Yearly\ Budget = 3600* 12[/tex]

i.e.

[tex]y = 3600 * 12[/tex]

An 8-foot piece of twine costs $5.76. What is the price per inch?

Answers

Answer:

$0.06

Step-by-step explanation:

First, find how many inches are in 8 feet.

Since 1 foot is 12 inches, multiply 8 by 12:

8(12)

= 96

Then, to find the price per inch, divide the price by the number of inches:

5.76/96

= 0.06

So, the price per inch is $0.06

Answer:

$0.06

Step-by-step explanation:

There are 12 inches in a foot, and there are 8 feet all together, meaning there is 96 inches for $5.76.

Divided the cost y the number of inches to get the cost per inch,

5.76 divided by 96 = 0.06.

A candy store sells caramels for $9/pound and chocolate for $12/pound. How much more is the cost of 2 pounds of caramel than 1.5 pounds of chocolate? *Show your work*

Answers

Answer:

The caramel is $0 more than the chocolate. In other words, they cost the same.

Step-by-step explanation:

Since we have 2 pounds of caramel and caramel costs $9/pound, the cost of 2 pounds of caramel can be found by this equation:

2lbs · $9 = $18

Since we have 1.5 pounds of chocolate and chocolate costs $12/pound, the cost of 1.5 pounds of chocolate can be found by this equation:

1.5lbs · $12 = $18

To find how much bigger the cost of caramel is than that of chocolate, we will subtract the total cost of the chocolate from the total cost of the caramel.

$18 - $18 = $0

Find the mean and the median of the data set. 31,32,36,31,30,35,33,30.

Answers

Answer:

Mean = 32.25

median = 31.5

Answer:

Median = 31.5

Mean  = 32.25

Step-by-step explanation:

Number of data = 8

Ascending order:

    30 , 30 , 31 , 31 , 32 ,  33 , 35, 36

Median = Average of 4th and 5th term

             = (31 + 32) / 2

              = 63/2

              = 31.5

Mean = Sum of all the observations /number of observations

         = (31 + 32 + 36 +31 + 30 + 35 + 33 +30) / 8

how would i slove for x??

Answers

Answer:

x=12

Step-by-step explanation:

First you need to find the 3rd angle.

180-118=x

x=62

Once you have that 3rd angle, set all the inside angles equal to 180

4x-6+5x+16+62=180 ---> set to 180

9x+72=180 -->combine like terms

9x=108 --> subtract 72 from both sides

x=12 -->divide both sides by 9

The question is missing parts. Here is the complete question.

Now that you've created your hypotheses, it's time to prove them. First look at the sum of two rational numbers. Let's say they are two rational numbers, x and y. Because they're rational, they can be written as a ratio of integers. Let [tex]x=\frac{a}{b}[/tex] and [tex]y=\frac{c}{d}[/tex], where a, b, c and d are integers and b and d do not equal 0. The process for finding the sum x + y in terms of a, b, c and d is shown in the figure below.

Based on the sum and using the closure property of integers, what conclusion can you make about the sum of two rational numbers? Explain your answer.

Answer: The sum of two rational numbers equals a rational number.

Step-by-step explanation: Rational number is defined as a number that can be made by dividing two integers.

Closure Property of Integers states the sum or subtraction of two integers always gives an integer.

Using the definition of rational and expanding the property, we can conclude that the sum of two rational numbers will result in a rational number, as demonstrated in the table below.
