Three students that share a townhouse find that their electric bill for October is $2.23 less than the September bill. The
total of both bills is $292.43, and each bill is split evenly among the roommates. How much did each owe in September?
Answers
Answer:
$47.48
Step-by-step explanation:
Let x = the amount owed Sept.
x + x - 2.23 = 292.43 Combine like terms
2x -2.23 = 292.43 Add 2.23 to both sides
2x - 2.23 + 2.23 = 292.43 + 2.23
2x = 294.66 Divide both sides by 2
\(\frac{2x}{2}\) = \(\frac{294.66}{2}\)
x = 147.33 this is the bill for September
Oct. 147.33 -2.23 = 145.10 This is the Bill for Oct.
Total:
147.33 + 145.10 = 292.43
292.43 ÷ 3 = 97.48 This is what each will owe rounded to the nearest penny.
The graph below shows the solutions to which inequality?
A. x^2-3x+3 ≥0
B. x² + 3x-3 <0
C. x²-3x+3<0
D. x² + 3x-3>0
Answers
The inequality expression that corresponds to the solution of the inequality graph is x² + 3x - 3 < 0.
option B.
What is the solution of the inequality?The inequality expression that corresponds to the solution of the inequality graph is determined by simplifying the equations as follows;
The solution of the graph,
x > -4 and x < 1
The first equation with "≥" is ruled out because the graph doesn't have a thick dot.
Let's simplify the second expression;
x² + 3x - 3 < 0
solve using quadratic formula;
x > -3.79 or x < 0.79
The third expression is ruled out since its solution will be complex.
For the last expression;
x² + 3x - 3 > 0
x < -3.79 or x > 0.79
Thus, the correct inequality expression is x² + 3x - 3 < 0.

The simple interest on 1600 with a 6% interest rate for 2 years is $192.
What is the simple interest?The simple interest simply means the method that's used to calculate the interest that's charged on a loan or money given out.
In this situation, we want to calculate the simple interest on 1600 with a 6% interest rate for 2 years. This will be calculated thus:
Simple interest = Principal × Rate × Interest
Simple interest = $1600 × 6% × 2
Simple interest = $1600 × 0.06 × 2
Simple interest = $192

Determine whether the quadrilateral is a parallelogram using the distance formula.
Q(-10, -2) R(1, 1) S(1, -7) T(-11, -8)
Answers
The quadrilateral is not a parallelogram
What is quadrilateral?Quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points.
we know that
In a parallelogram opposite sides are parallel and congruent
Find the length of the sides of the quadrilateral
step 1
Find the distance QR
the formula to calculate the distance between two points is equal to
d= √( y2- y1)² +( x2 -x1)²
we have
Q(-10,-2), R(1,-1)
substitute
d=√ (-1 + 2)² + (1 + 10)²
d =√( 1 ) ²+ ( 11)²
d =√122 units
step 2
Find the distance TS
the formula to calculate the distance between two points is equal to
d= √( y2- y1)² +( x2 -x1)²
we have
T(-11,-8), S(1,-7)
substitute
d =√ (- 7 + 8)² + (1 + 11 )²
d =√( 1 )² + (12) ²
d = √145 units
we have that
QR and TS are opposite sides
In a parallelogram opposite sides are congruent but in this problem
QR≠TS
√122 units ≠ √145 units
therefore
The quadrilateral is not a parallelogram

Answers
okay, first to figure out the IQR of the table you need to organize them from least to greatest.
2.43, 6.14, 6.47, 7.19, 8.38, 8.63
to find the middle number of all of these you add them all together and divide by 6, which is the total amount of numbers there.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 = 39.24
39.24 / 6 = 6.54
now that we have the IQR, next we find the outlier. to find the outlier you multiply the IQR by 1.5 which is 6.54 x 1.5 = 9.81 <- outlier
Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 + 9.81 = 49.05
49.05 / 7 = 7.00 (Rounded)

Domain of a function includes all possible values of x that are plotted on the x-axis on a grid.
The range includes all possible y-values.
The graph of the function given above has specific points that are marked clearly. Each specific values if x and y are clearly known.
Therefore, the domain of the function are -2, 2, and 4.
This can be written properly as {x | x = -2, 2, 4}

The value of x is given as follows:

The measure of angle DFE is given as follows:
<DFE = 62º.
How to obtain the measures?To obtain the measures, we consider that the sum of the measures of the internal angles of a triangle is of 180º.
The internal angle measures for this problem are given as follows:
180 - (5x - 14) -> each angle is supplementary with it's external.44º.3x - 10.Hence the value of x is obtained as follows:
180 - 5x + 14 + 44 + 3x - 10 = 180
228 - 2x = 180
2x = 48
x = 24.
The measure of angle DFE is obtained as follows:
<DFE = 3(24) - 10
<DFE = 72 - 10
<DFE = 62º.

\((x,y)\)And in Polar Form:
\((r,\theta)\)In this case, you can identify that:
\(\begin{gathered} x=1 \\ y=\sqrt{3} \end{gathered}\)In order to convert them to Polar Form, you need to use these formulas:
\(\begin{gathered} x=r\cdot cos\theta \\ y=r\cdot sin\theta \end{gathered}\)Use this formula to find "r":
\(r=\sqrt{x^2+y^2}\)Then, this is:
\(r=\sqrt{1^2+(\sqrt{3})^2}=2\)You need to find the angle. You can use this formula:
\(\theta=tan^{-1}(\frac{y}{x})\)Therefore the angle is:
