zack made this table for his survey? grape 16, orange 10, berry 9, apple 12 how many votes were cast?

Answer:

Step-by-step explanation:

Alright, lets get started.

Since we know,

[tex]3.28084 feet = 1 meter[/tex]

So,

[tex]1 feet = \frac{1}{3.28084} meter[/tex]

[tex]1 cubic feet= \frac{1}{3.28084} *\frac{1}{3.28084}* \frac{1}{3.28084}cubic meters[/tex]

Hence

[tex]1 cubic feet = 0.0283168 cubic meters[/tex]

So, 30000 cubic feet = [tex]30000*0.0283168 = 849.5[/tex] cubic meters

hence the answer is 849 cubic meters. :   Answer

Step-by-step explanation:

Let

x------> represents the number of AA batteries

y------> represents the number of 9V batteries

we know that

The constraints are

[tex]x\geq 6[/tex]

[tex]x\leq 12[/tex]

so

[tex]6\leq x\leq 12[/tex] --------> inequality A    

[tex]y\leq 15[/tex] --------> inequality B

[tex](x+y)\geq 20[/tex]        

[tex](x+y)\leq 27[/tex]

so

[tex]20\leq (x+y) \leq 27[/tex]-----> inequality C

The solution of the system of inequalities is the shaded area in the attached figure

If a ordered pair meet all the constraints and make sense in the context of the situation, then the ordered pair is a solution of the system of inequalities

let's check each of the ordered pairs

case A) point [tex](7,13)[/tex]      

[tex]x=7\ y=13[/tex]

Verify inequality A

[tex]6\leq 7\leq 12[/tex]--------> is true

Verify inequality B

[tex]13\leq 15[/tex] -------> is true

Verify inequality C

[tex]20\leq (7+13) \leq 27[/tex]

[tex]20\leq (20) \leq 27[/tex]------> is true

The ordered pair  [tex](7,13)[/tex] meets all restrictions, therefore the ordered pair is a solution of the system of inequalities

case B) point [tex](8,11)[/tex]      

[tex]x=8\ y=11[/tex]

Verify inequality A

[tex]6\leq 8\leq 12[/tex]--------> is true

Verify inequality B

[tex]11\leq 15[/tex] -------> is true

Verify inequality C

[tex]20\leq (8+11) \leq 27[/tex]

[tex]20\leq (19) \leq 27[/tex]------> is not true

The ordered pair  [tex](8,11)[/tex]   does not meet all the restrictions, therefore the ordered pair is not a solution of the system of inequalities.

case C) point [tex](10,16)[/tex]      

[tex]x=10\ y=16[/tex]

Verify inequality A

[tex]6\leq 10\leq 12[/tex]--------> is true

Verify inequality B

[tex]16\leq 15[/tex] -------> is not true

Verify inequality C

[tex]20\leq (10+16) \leq 27[/tex]

[tex]20\leq (26) \leq 27[/tex]------> is not true

The ordered pair  [tex](10,16)[/tex]   does not meet all the restrictions, therefore the ordered pair is not a solution of the system of inequalities.

case D) point [tex](12,12)[/tex]      

[tex]x=12\ y=12[/tex]

Verify inequality A

[tex]6\leq 12\leq 12[/tex]--------> is true

Verify inequality B

[tex]12\leq 15[/tex] -------> is true

Verify inequality C

[tex]20\leq (12+12) \leq 27[/tex]

[tex]20\leq (24) \leq 27[/tex]------> is true

The ordered pair   [tex](12,12)[/tex]  meets all restrictions, therefore the ordered pair is a solution of the system of inequalities

the answer is

[tex](7,13)[/tex]

[tex](12,12)[/tex]

To solve problems with integers and rational numbers, one should apply operations' properties such as commutativity, associativity, and distributivity, which streamline calculations and assist in combining numbers in an order that simplifies the process.

Integers and rational numbers are essential elements of algebra that allow for diverse mathematical operations. Integers are the set of whole numbers including zero, and their negative counterparts (e.g., -1, 0, 1), while rational numbers are ratios of integers (e.g., 2/1, 3/4) that can represent fractions and decimals that terminate or repeat. When solving problems, it is crucial to remember the properties of operations, which include commutativity associativity , distributivity, the additive inverse and the multiplicative inverse.

For example, when adding fractions with different denominators, you find a common denominator and use commutativity and associativity to combine these fractions. A problem involving multiplication of a negative integer and a fraction may require both the distributive property and understanding of the multiplicative inverse. Mastering these properties provides a foundation for solving algebraic expressions and equations, ensuring accuracy whether the numbers are complex, real, rational, or integers.

The edge length of a Rubik's cube, given a face perimeter of 22.2 cm is 5.55 cm.

The question asks for the length of an edge of a Rubik's cube, given that the perimeter of each face of the cube is 22.2 cm. A Rubik's cube is a square based cube, meaning each face of the cube is a square.

In a square, all sides have equal length and the perimeter is four times the length of one edge. Therefore, to find the length of one edge, you divide the perimeter of the square by four. Using the provided perimeter of 22.2 cm, the length of an edge would be 22.2 ÷ 4 = 5.55 cm

Use 1.75 cups of blue and 1 cup of yellow

The given problem can be placed in the category of ratios and proportions. There is a ratio of color mixing which contains the proportion of two colors i.e blue and yellow. When we use 2 cups of yellow with 3.5 cups of yellow then we get green color so if we mix half of their amounts then we can get less or simply half amount of color too. Hence adding 1 cup of yellow and 1.75 cup of blue will give us small amount in result.

The width of the rectangle can be any number less than or equal to 15 inches. If the width also must be at least 10 inches and a whole number, then it can be any of the whole numbers between 10 and 15, inclusive.

You're correct, the initial inequality does solve for w, the width of the rectangle. The inequality 80 - 2w ≥ 50 simplifies to 2w ≤ 30 and further simplified to w ≤ 15. This means that the width of the rectangle can be any number less than or equal to 15 inches.

For the second part of the question, if we also know that the width must be at least 10 inches and it must be a whole number, we can adjust the solution to be an integer number between 10 and 15, inclusive. So the possible values for width would be 10, 11, 12, 13, 14, or 15 inches in this case.

https://brainly.com/question/30013680

#SPJ12

To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. If the width must be at least 10 inches and a whole number, then the solution changes.

To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. We can do this by adding 2w to both sides of the inequality:

80 - 2w + 2w ≥ 50 + 2w
80 ≥ 50 + 2w
30 ≥ 2w
15 ≥ w

So, the width of the rectangle must be less than or equal to 15 inches.

If the width must be at least 10 inches and a whole number, then the solution changes. In this case, w can only take on whole number values from 10 to 15, inclusive. So, the width of the rectangle can be 10, 11, 12, 13, 14, or 15 inches.

The distance function for Aubrey and Charlie's trip is d(t) = 20 + 50t, accounting for an initial 20 miles already traveled. The reasonable domain for time t in this situation is from 0 to 2 hours since they are traveling at 50 miles per hour and have 100 miles remaining.

Aubrey and Charlie have already traveled 20 miles and are continuing to travel towards a city that is 120 miles away from their start at a constant rate of 50 miles per hour. To complete the function that models the distance they drive as a function of time, we use the formula distance traveled is velocity  imes time. With a start of 20 miles, the function can be written as:

d(t) = 20 + 50t

Where d(t) represents the distance traveled at time t in hours. For the domain, since they have already traveled 20 miles, the remaining distance is 100 miles. At a rate of 50 miles/hour, the maximum time needed to cover the remaining distance is 2 hours. Hence, the reasonable domain for time t is 0 ≤ t ≤ 2.
