Answer:
360 degrees is the sum of the exterior angles of a nonagon.
Use the best method to solve each equation. Write answer as an ordered pair. Check your answers. 3x-y=18 Y=x-4
Answer:
Solution → (7, 3)
Step-by-step explanation:
Given system of equations is,
3x - y = 18 -------(1)
y = x - 4 ------- (2)
Substitution method is the best method to solve the given system of equations.
Substitute the value of y from equation (2) to equation (1)
3x - (x - 4) = 18
3x - x + 4 = 18
2x = 18 - 4
2x = 14
x = 7
From equation (2)
y = 7 - 4
y = 3
Solution of the system of equations will be (7, 3).
Which expression is NOT equivalent to 40 + 20
Answer:
4(10 + 16)
Step-by-step explanation:
40 + 20 = 60, so none of the answers can be 60.
Let's look at all of the answer choices:
10(4 + 2) = 60
4(10 + 16) = 104 (this is the answer!)
5(8 + 4) = 60
2(20 + 10) = 60

The unadjusted net income statement was $46850. After journalizing and posting the adjusted entry for the $2300 of dupplies used during the year, the adjusted net income is
Answer: $44,550
Step-by-step explanation:
Supplies used during the period are treated as expenses to the business so have to be deducted from net income.
If the supplies for the year was $2,300, the net income would be adjusted as follows:
= 46,850 - 2,300
= $44,550
The art club is designing a rectangular mural for the school hallway. Three corners are located at (-1, -1), (-1, 1), and (4, 1) on teh coordinate plane. What would be the forth vertex on the coordinate plane below?
Answer:
The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.
Step-by-step explanation:
Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:
[tex]X(x,y) = (a, c)[/tex] (1)
[tex]Y(x,y) = (a, d)[/tex] (2)
[tex]Z(x,y) = (b, c)[/tex] (3)
[tex]W(x,y) = (b, d)[/tex] (4)
[tex]a < b[/tex] (5)
[tex]c < d[/tex] (6)
If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:
[tex]X(x,y) = (-1, -1)[/tex]
[tex]Y(x,y) = (-1, 1)[/tex]
[tex]Z(x,y) = (4, -1)[/tex]
[tex]W(x,y) = (4,1)[/tex]
Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].

S. The area of a stage for a concert is 216 square feet. The length is 6 times the width. Find the dimensions of
the stage
Answer:
Width=6 Length=36
Step-by-step explanation:
The stage is rectangular since the length is not equal to width.
We use the formula (Width × Length) to obtain the area of any rectangle.
But the Length is 6 times the Width, therefore we equate the formula for the area of stage as
Width × 6Width = 216
we get Width as 6 and 6width which is the length as 36

Angel has a bag that contains orange chews, cherry chews, and lime chews. He performs an experiment. Angel randomly removes a chew from the bag, records the result, and returns the chew to the bag. Angel performs the experiment 52 times. The results are shown below:
A orange chew was selected 10 times.
A cherry chew was selected 20 times.
A lime chew was selected 22 times.
Based on these results, express the probability that the next chew Angel removes from the bag will be a flavor other than lime as a percent to the nearest whole number.
Answer:
58%
Step-by-step explanation:
Just do 0.576923 times 100% & you should get 57.6923% than round because it says nearest whole number so that's how your answer is 58% :)
Sheila works at a fine jewelry store and earns a commission on her total sales for the week. She earned $900 in commission this week. She sold $23,000 worth of jewelry to earn that commission. Express her rate of commissions a percent.
Answer:
3.913%
Step-by-step explanation:
We are given that Sheila earned is commission $900 for selling $23,000 worth of jewelry, and we are asked to find the rate of her commissions as a percent.
The rate of commissions would basically just be what percent of the money made does she get. Since Sheila sold $23,000 worth of jewelry and got $900 for doing so, her rate of commission would be:
900 ÷ 23,000 ≈ 0.03913
Which expressed as a percent is:
3.913%
So her rate of commissions would be 3.913%.

An account with an initial balance of $5000 earns 5% interest for 3.5 years.
What is the ending balance?
Enter your answer in the box.
20 POINTS
Answer:
$875
Step-by-step explanation:
5000 x 0.05 x 3.5 = $875
The ending balance is =$5875
Simple interest of an account:Simple interest is calculated with the formula below:
[tex]si = \frac{p \times t \times r}{100} [/tex]
where, initial balance (principal) = $5000
time = 3.5 years
rate= 5
[tex]si = \frac{5000 \times 3.5 \times 5}{100} [/tex]
[tex]si = \frac{87500}{100} [/tex]
[tex]si = 875[/tex]
Therefore the ending balance is= simple interest+ initial balance
Ending balance = 5000+ 875
= $5875

The perimeter of the Octagon is P = 30 feet
What is the perimeter of a polygon?The perimeter of the regular polygon with apothem and area is given by the equation
Perimeter of Polygon P = ( Area x 2 ) / Apothem
where apothem is a line from the center of a regular polygon at right angles to any of its sides
Given data ,
Let the perimeter of the octagon be represented as P
Now , the apothem a = 6 feet
The area of octagon A = 120 feet²
where Perimeter of Polygon P = ( Area x 2 ) / Apothem
P = ( 120 x 2 ) / 6
P = 30 feet

Which statement below about roots is false.Immersive Reader (5 Points) Simplified radicals have a positive and a negative root. A radicand is the symbol used when working with roots. Exponents and Roots are inverses Roots can be squared, cubed, quadrupled. Or more.
Answer:
Statement (B)
Step-by-step explanation:
Which statement below about roots is false?
Let's arrange the statements by assigning option-letters a, b, c, d to them.
(A) Simplified radicals have a positive and a negative root.
This is true, as the root of any number is either a positive or a negative; especially if the rooting index is an even number like 2 or 4. For example, the square root (when the index is 2) of 9 is either +3 or -3. To check, find their squares. +3 x +3 = 9 and -3 x -3 = 9.
(B) A radicand is the symbol used when working with roots.
This statement is false, as the name for the symbol used in root operations is "radical symbol". A radicand is the number or expression whose roots are about to be found. It is the expression that lies under or inside the radical symbol!
(C) Exponents and Roots are inverses.
Exponents are the powers to which mathematical expressions are raised. Roots are the indexes by which mathematical expressions are divided. Exponents are hence the opposites or inverses of roots.
(D) Roots can be squared, cubed, quadrupled, or raised to higher powers.
Yes! The root of a mathematical expression or figure can be raised to any number or power, be it 2 (square), 3 (cube), 4 (quadruple), 5 (quintuple) or 100 (cent).

Group Like Terms: 4x+2x - 6 = 3(2x-2)
Add Similar Elements (4x+2x=6x): 6x - 6 = 3(2x-2)
Expand: 3(2x-2) ; 6x - 6
6x - 6 = 6x - 6
Add 6 to Both Sides: 6x - 6 + 6 = 6x - 6 + 6t: 6x - 6x = 6x - 6x
Simplify: 6x = 6x
Subtract: 6x - 6x
