Answer:
14[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Make equivalent fractions with all the same denominator. Let's us 12 as our common denominator
[tex]\frac{1}{3}[/tex] x [tex](\frac{4}{4})[/tex] = [tex]\frac{4}{12}[/tex] Another name for [tex]\frac{4}{4}[/tex] is 1. (4 divided by 4 is 1) I am just making an equivalent fraction of [tex]\frac{1}{3}[/tex]
[tex]\frac{3}{4}[/tex] x [tex](\frac{3}{3})[/tex] = [tex]\frac{9}{12}[/tex] another name for [tex]\frac{3}{3}[/tex] is 1 (3 divided by 3 is 1) I am just making an equivalent fraction of [tex]\frac{3}{4}[/tex].
Now that my denominators are all the same size I can see how many 12's I have.
6 [tex]\frac{4}{12}[/tex] + 4 [tex]\frac{9}{12}[/tex] + 3 [tex]\frac{7}{12}[/tex] I can rearrange this to add all the whole numbers together and all of the fractions together.
6 + 4 + 3 = 13
[tex]\frac{4}{12}[/tex] + [tex]\frac{9}{12}[/tex] + [tex]\frac{7}{12}[/tex] = [tex]\frac{20}{12}[/tex] I have 20 12ths. every [tex]\frac{12}{12}[/tex] makes another whole, so
[tex]\frac{20}{12}[/tex] 1 whole with [tex]\frac{8}{12}[/tex] Left over. If we put this all together, we have
13 + 1 + [tex]\frac{8}{12}[/tex]
14 [tex]\frac{8}{12}[/tex] To simplify this. I will divide [tex]\frac{8}{12}[/tex] ÷ [tex]\frac{4}{4}[/tex] = [tex]\frac{2}{3}[/tex].
the final answer is 14 [tex]\frac{2}{3}[/tex]

One day total attendance at the state fair was 126,945. Round 126,945 to the nearest ten thousand, nearest ten thousand and the nearest thousand. Which of these rounded amounts is closest to the actual attendance?
Answer: To the nearest thousand.
Step-by-step explanation:
First, we will round 126,945 to the requested place values;
(it says ten thousand once, so I'm going to include hundred thousand)
hundred thousand ➜ 126,945 ➜ 100,000
ten thousand ➜ 126,945 ➜ 130,000
thousand ➜ 126,945 ➜ 127,000
Next, we will subtract these values from 126,945, and see which absolute value is the smallest.
hundred thousand ➜ 126,945 - | 100,000 | = 26,945
ten thousand ➜ 126,945 - | 130,000 | = 3,050
thousand ➜ 126,945 - | 127,000 | = 55
The rounded amount that is closest to the actual attendance is thousand.

The number of species, N, on an island as a function of the area, A, of the island is N=kA‾‾√3.
(a) What is the exponent of this power function?
-[tex]\sqrt{3}[/tex] is the exponent of the power function.
The power function is generally just f(x) = c x^p for some constant c and some real number exponent p. (It can only be defined for positive values of x.) For example, the square root function f(x) = √x is a power function with p = 1/2.
In this case, N=kA‾‾√3 , -[tex]\sqrt{3}[/tex] is the exponent of this function.

The exponent of the power function is 1/2.
How often we are multiplying a number by itself is indicated by its exponent. To multiply 3 four times, for instance, we get 34. It is 3333 in its enlarged form. A number's power is another name for an exponent. It may take the form of an integer, a fraction, a negative integer, or a decimal.
A fractional exponent is one where the exponent of a number is a fraction. Parts of fractional exponents include square roots, cube roots, and nth roots. Square root of the base is a number having a power of half.
Hence we get the exponent of the function as 1/2.

The probability to win 25$ and 2$ are 1/18 and 1/6
Probability is the ratio of favorable cases to total sample cases.
If two dice are rolled,
Total sample cases or combinations= 6x6=36
The favorable cases to get 2 or 12 ={1,2}{6,6}= 2 total cases
The favorable cases to get 7 ={1,6}{6,1}{2,5}{5,2}{3,4}{4,3}=6 cases
The probability to win 25$=2/36=1/18

Given data:
If you rolled two dice and got a sum of 2 or 12, you won $25. If you rolled a 7, you won $2. Any other roll was a loss. It cost $1 to play one game with one roll of the dice.
Solving part
Step-by-step explanation:
For 2 and 12
Number of possible outcomes = 2
Gain = 25 -1 = $24
For 7
Number of possible outcomes = 6
Gain = 5-1 = $4
For others
Number of possible outcomes = 36-(4+6) = 26
Gain = -$1
Expectation of the gain;
X= (2×$24 + 6×$4 - 26×1)/36
X = $46/36

The difference of two numbers is 6. Twice the smaller is 4 more than the larger. Find the larger
number
Answer:
16
Step-by-step explanation:
Difference means subtract
Let the two numbers be x and y
x-y = 6
Let y be the smaller number
2y = x+4
Using substitution
x = 6+y
2y = 6 +y +4
2y = y+10
Subtract y from each side
2y-y = y+10-y
y = 10
Now we need to find x
x-y = 6
x-10 = 6
Add 10 fo each side
x-10+10 =6+10
x = 16

companies online that sell stuffed mascots.
a.
Which company has the lowest cost per tiger?
b. If they use that company, how much profit

a) The lowest cost per tiger is $2.74, according to Company C. (Divide the costs by how many stuffed animals there are; in this case, it's $41.10/15).
b) They would make $2.26 profit for each tiger sold.
How to know which company has the lowest cost per tiger and how much profit will the students make for each tiger sold?You must divide the pricing by the anticipated number of sales to determine how much money customers must pay for each plush toy. For Company C, the calculation would be $41.10 divided by 15. You'll discover that Company C is the least expensive of all the companies when you do that.
By deducting $2.74 from $5, you can calculate their profit.
Although they had to spend $2.74 to purchase the plush animals, they are selling it for $5. $5 - $2.74 = $2.26

d=4cd=4cd, equals, 4, c
Identify the dependent and independent variables.
The number of boxes of cookies Kai buy : independent variable
The amount of the cookies will cost in dollars : dependent variables
Based on the given conditions, formulate,
Each box of cookies costs is = \$4$4dollar (sign, 4).
Cookie represented by c
The required equation is,
d = 4cd = 4cd = 4c
The price is determined by the number of cookies purchased.
c is the independent variable
when c is changes d is changed
So, d is the dependent variable
variables of the equation.
So,
We can write,
d = 4c
where d represents the cost of cookies in dollar and c represents the number of boxes of cookies.
Then, the cost of each box of cookies is $4.
It means,
The cost of 1 box of cookies is = $4.
The cost of 2 boxes of cookies is = $(4+4) = $(2×4)
The cost of 3 boxes of cookies is = $(4+4+4) = $(3×4)
The cost of cookies = (Number of boxes × 4)
The required equation is,
d = 4c
where d represents the cost of cookies in dollar and c represents the number of boxes of cookies.
Therefore,

A new Community Sports Complex is being built in Del Rio. The perimeter of the rectangular playing field is 354 yards.
The length of the field is 7 yards less than triple the width. What are the dimensions of the playing field?
We need to know about the perimeter of a rectangle to solve this problem.The length of the field is 131 yards and width is 46 yards.
The perimeter of a rectangle is the summation of it's length and breadth, the longer side of a rectangle is called length and the shorter side is called breadth. The perimeter of a rectangle is given by the formula 2(l+b) where l is the length of the rectangle and b is the breadth of the rectangle. In this question we have been told the perimeter of the rectangular field is 354 yards. The length of the field is 7 yards less than triple the width. Let the width of the field be x yard, then the length is
length=3x-7
Then perimeter in terms of x= 2(l+b)=2((3x-7)+x)=2(4x-7)=8x-14
8x-14=354
8x=368
x=46
Then breadth=46 yards
length =3x-7=138-7=131 yards
Therefore we found out the dimensions of the field to be, the length is 131 yards and breadth is 46 yards.

Answer:

Step-by-step explanation:
We know that (4x + 7) + (2x + 5) add up to a straight angle = 180 degrees, so we have the equation 4x + 7 + 2x + 5 = 180.
By combining like terms, we get 6x + 12 = 180.
Subtract 12 from both sides of the equation to get 6x = 168. Divide both sides by 6 and you get x = 28.
