540 = a/11
5940 = x
Answer: x = 5940
Answer: [tex]a=5,940[/tex]
Step-by-step explanation:
Given the equation [tex]540=\frac{a}{11}[/tex], you need to find the value of "a", then, you need to solve for "a".
You need to apply the Multiplication property of equality, which establishes that:
[tex]If\ a=b,\ then\ a*c=b*c[/tex]
Therefore, based on this property, you can multiply both sides of the equation by 11.
Then, you get the following solution:
[tex](11)(540)=(\frac{a}{11})(11)\\\\a=5,940[/tex]
what are the next three terms in the sequence -1, 9, 19, 29
39. each term is ten more than the term before it :)
Answer:
39, 49, 59
Step-by-step explanation:
Note the difference between consecutive terms
9 - (- 1) = 9 + 1 = 10
19 - 9 = 10
29 - 9 = 10
The difference is a constant + 10
To obtain the next term in the sequence add 10 to the previous term
29 + 10 = 39
39 + 10 = 49
49 + 10 = 59
The next 3 terms are 39, 49, 59
One half the difference of the cube of a number, x, and three
Answer:
(1/2)(x³ - 3)
Step-by-step explanation:
That would be (1/2)(x³ - 3).
The expression ' one-half difference of a number cubed and one' is written as [tex]\frac{1}{2} (x^3 - 1)[/tex].
Let the number be [tex]x[/tex].
The cube of the number is [tex]x^3[/tex].
Difference of the cube of the number with [tex]1[/tex] is [tex]x^3 - 1[/tex].
Now, one-half difference of a number cubed and one is represent as,
[tex]\frac{1}{2} (x^3 - 1)[/tex].
So, the expression ' one-half difference of a number cubed and one' is written as [tex]\frac{1}{2} (x^3 - 1)[/tex].

About how many feet of fencing are needed to enclose a rectangular garden with a 30 foot pond side and a 40 foot long diagonal
Answer:
140
Step-by-step explanation:
30+30=60
40+40=80
60+80=140
Answer: Hello there!
If you want to enclose a rectangular garden, then the feet of fencing that you need are equal to the perimeter of the rectangle, this is, the sum of all the sides of the rectangle.
We know that the rectangle has a 30ft pond side and a 40ft long diagonal.
this 40ft diagonal is the hypotenuse of a triangle rectangle where the cathetus is the sides of the rectangle; we know that one of the sides are of 30 ft, and we want to find the other:
Using the Pythagorean theorem; we know that:
[tex]40^{2} = 30^{2} + x^{2}[/tex]
where x is the length of the other side that we don't know yet.
[tex]x = \sqrt{40^{2} - 30^{2} } = 26.5ft[/tex]
Then your rectangle has a 30ft side, and a 26.5ft side (and has two of both)
Then the perimeter is:
30ft + 30ft + 26.5ft + 26.5ft = 113ft
Find the slope and y-intercept of the line. y=-x+7
Answer:
slope = - 1, y- intercept = 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 7 ← is in slope- intercept form
with slope m = - 1 and y- intercept c = 7
The slope of the line y = -x + 7 is -1, and the y-intercept is 7.
To determine the slope and y-intercept of the line given by the equation y = -x + 7, we first recognize that it is in slope-intercept form, which is y = mx + b.
Identify the slope (m): In the equation y = -x + 7, the coefficient of x is -1. Thus, the slope of the line is -1.
Identify the y-intercept (b): The constant term in the equation is 7. Thus, the y-intercept is 7, meaning the line intersects the y-axis at the point (0, 7).
The slope of the line y = -x + 7 is -1, and the y-intercept is 7.
The high school field hockey team needs to buy new practice uniforms. The company the team is ordering from charges $250.00 for a one time print layout fee and then $28.00 for each uniform. What is the maximum number of uniforms the team can buy and stay within its budget of $550.00?
Answer:
10 uniforms
Step-by-step explanation:
You will start by subtracting 250 from 550 to get 300. You will then divide 300 by 28 to get the total number of uniforms. You will get the answer 10.7, but because we are dealing with uniforms, we will remove the decimal and just use 10.

When a fraction equals zero :

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
6n-17
————— • 6 = 0 • 6
6
Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
6n-17 = 0
Solving a Single Variable Equation :
6.2 Solve : 6n-17 = 0
Add 17 to both sides of the equation :
6n = 17
Divide both sides of the equation by 6:
n = 17/6 = 2.833
One solution was found :
n = 17/6 = 2.833

Answer:
C) Multiply 3x by 6 in the first equation and subtract the second equation.
Step-by-step explanation:
We have been given a system of equations.[tex]3x+3y = 4[/tex] and [tex]18x-9y = 12[/tex]. We are asked to choose the "incorrect" step that will make "not" produce a system with the same solution.
Let us see our give choices one by one.
A) multiply the first equation by 6 and subtract the second equation.
When we will multiply 1st equation by 6, the coefficient of x would be 18. When we will subtract 2nd equation the both x's will cancel out. Therefore, option A is correct.
B) multiply the first equation by −6 and add the second equation.
When we will multiply 1st equation by -6, the coefficient of x would be -18. When we will add 1st equation to 2nd equation the both x's will cancel out. Therefore, option B is correct as well.
C) Multiply 3x by 6 in the first equation and subtract the second equation.
We need to remember that we cannot multiply only one term of equation by some quantity as it will make the whole equation false, therefore, option C is incorrect.

What is the total number of different 6-letter arrangements that can be formed using the letters in the word QUASAR?
There are 720 different 6-letter arrangements that can be formed using the letters in the word QUASAR, calculated by 6 factorial (6!).
Explanation:The question asks for the total number of different 6-letter arrangements that can be formed using the letters in the word QUASAR. This is a problem of permutations where all the letters are distinct. To find the number of different permutations of the letters in QUASAR, we multiply the number of choices available at each position. There are 6 choices for the first letter, 5 for the second, and so on, until 1 choice for the last letter.
Therefore, the permutations are calculated as 6 × 5 × 4 × 3 × 2 × 1, which is equal to 6! (6 factorial).
The calculation of 6! is as follows:
6 × 5 × 4 × 3 × 2 × 1 = 720.So, there are 720 different 6-letter arrangements that can be formed from the word QUASAR.

What is the solution to the system of equations?
Answer:
There are infinitely many solutions. It is the same line.
Step-by-step explanation:
If you start by multiplying the first equation by 2 to get rid of the fractions, you get -x + y = -2. If you solve it for y, you get y = x - 2. The second equation can be solved for y also, giving you y = x - 2. That means they are the same line and the solution to this situation is infinitely many solutions because all the points on one line are identical to the points on the other line because they are the same line.

Okay so if the regular price of the shirt is 100% as $25 and you have a 30% discount you are still paying 70% (100-30=70) so 70% as a decimal is .70 and $25 x .70 is $17.50. Therefore the shirt is $17.50 after the discount.
Alright so, what it’s basically asking for is 70% of 25. This is the price of the shirt after you’ve accounted for the 30% discount
Then you would multiply 25 by .70, giving you $17.50

Explain what type of function is the best model for the data set and justify your choice. Help???????
Answer:
The function is linear
Step-by-step explanation:
* Lets check from the table the type of the function
- At first check if it is linear or not
- The points are:
(165 , 198) , (168 , 201.6) , (170 , 204) , (172 , 206.4) , (175 , 210)
* Find the slope for each two points if the value of the slop is
constant, then the function will be linear
∵ The slop = (y2 - y1)/(x2 - x1)
∴ m1 = (201.6 - 198)/(168 - 165) = 1.2
∴ m2 = (204 - 201.6)/(170 - 168) = 1.2
∴ m3 = (206.4 - 204)/(172 - 170) = 1.2
∴ m4 = (210 - 206.4)/(175 - 172) = 1.2
∵ m1 = m2 = m3 = m4
# Note: You can use any to points to find the slope you will
have the same value
∴ The graph of the points is a line with slope 1.2
* The function is linear
Answer:
A linear function is the best model.
The ratio of y to x for the ordered pairs is constant, so the relationship is a direct variation. A direct variation is a type of linear function.
When the data set is plotted, it forms a line.
