Step-by-step explanation:
Given:
Fixed expenses = $475
Expense raised by = 5%
We need to find updated Total Fixed Expenses.
Amount of expense raised is equal to Percentile expense raised multiply by Fixed expenses and then Divided by 100.
framing in equation form we get;
Amount of expense = [tex]\frac{5}{100}\times 475 = \$23.75[/tex]
Now Updated Total Fixed expense will be equal to sum of Fixed expenses and Amount of expense raised.
framing in equation form we get;
Updated Total Fixed expense = $475 + $23.75 = $498.75
Hence The updated Total fixed expenses will be $498.75.

in trapezium abcd, as shown in the figure, ab is parallel to dc, ad=dc=bc=20cm and ‹a=60°. find: (i) length of ab (ii) distance between ab and dc
Answer:
AB = 40 cm
Distance = [tex]10\sqrt{3}[/tex] cm
Step-by-step explanation:
Draw two heights DE and CF. These heights together with bases of trapezoid form rectangle DEFC. In this rectangle, DC=EF=20 cm.
Consider right triangle ADE. In this triangle, angle ADE has the measure of 30° (the sum of the measures of all interior angles is always 180°, so m∠ADE=180°-60°-90°=30°)
Leg opposite to 30° angle is equal to half of the hypotenuse, so
[tex]AE=\dfrac{1}{2}AD=\dfrac{1}{2}\cdot 20=10\ cm[/tex]
Similarly, in triangle CBF, BF=10 cm.
Hence,
[tex]AB=AE+EF+FB=10+20+10=40\ cm[/tex]
The height of the trapezoid (the second leg of triangle ADE) is the distance between DC and AB. By the Pythagorean theorem,
[tex]AD^2=AE^2+DE^2\\ \\DE^2=20^2-10^2=400-100=300\\ \\DE=\sqrt{300}=10\sqrt{3}\ cm[/tex]
An employee at a party store is assembling balloon bouquets. For a graduation party, he assembled 2 small balloon bouquets and 3 large balloon bouquets, which used a total of 75 balloons. Then, for a Father's Day celebration, he used 33 balloons to assemble 2 small balloon bouquets and 1 large balloon bouquet. How many balloons are in each bouquet?
There are 6 balloons in small bouquet and 21 balloons in large bouquet.
Step-by-step explanation:
Let,
Number of balloons in small balloon bouquet = x
Number of balloons in large balloon bouquet = y
According to given statement;
2x+3y=75 Eqn 1
2x+y=33 Eqn 2
Subtracting Eqn 2 from Eqn 1
[tex](2x+3y)-(2x+y)=75-33\\2x+3y-2x-y=42\\2y=42[/tex]
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{42}{2}\\y=21[/tex]
Putting y=21 in Eqn 2
[tex]2x+21=33\\2x=33-21\\2x=12[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]
There are 6 balloons in small bouquet and 21 balloons in large bouquet.

Final answer:
In solving the system of linear equations, we determined that a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.
Explanation:
Solving a System of Equations
Let's denote the number of balloons in a small bouquet as s and in a large bouquet as l. The given problem provides us with two equations based on the information about the graduation party and Father's Day celebration:
For the graduation party: 2s + 3l = 75
For the Father's Day celebration: 2s + l = 33
Now we solve this system of linear equations to find the values of s and l. Subtracting the second equation from the first gives us:
2s + 3l - (2s + l) = 75 - 33
Which simplifies to:
2l = 42
Dividing by 2 gives us:
l = 21
Now we can plug in the value of l into any of the original equations to find the value of s. Let's use the Father's Day equation:
2s + 21 = 33
Subtracting 21 from both sides gives us:
2s = 12
Finally, dividing by 2 gives us:
s = 6
Therefore, a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.

given: <1 and <2 and supplements, <3 and <4 are supplements, and <1 ≅ <4
prove: <2 ≅ <3
By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3
Step-by-step explanation:
The supplementary angles are:
Two angles their sum is 180°The supplement of an acute angle is an obtuse angle and vice versaThe supplement of a right angle is a right angleIf one angle is supplement to two other angles, then the two angles are equal in measure (if 50° is supplement to angles X and Y, then X and y must be 130°)Supplement angles of congruent angles are congruent (If angles X and Y are supplement to angles A , B and angles A , B are congruent, then angles X and Y are congruent∵ ∠1 and ∠2 are supplementary
∴ m∠1 + m∠2 = 180° ⇒ (1)
∵ ∠3 and ∠4 are supplementary
∴ m∠3 + m∠4 = 180° ⇒ (2)
We can equate the left hand sides of (1) and (2) because the right hand sides are equal
∴ m∠1 + m∠2 = m∠3 + m∠4 ⇒ (3)
∵ ∠1 ≅ ∠4
∴ m∠1 = m∠4
- Substitute m∠4 by m∠1 in (3)
∴ m∠1 + m∠2 = m∠3 + m∠1
- Subtract m∠1 from both sides
∴ m∠2 = m∠3
∴ ∠2 ≅ ∠3
By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3

B is the midpoint of AC. If: AB = 9x+1 and BC= 6x+25 Find AC
Answer:
AC = 146
Step-by-step explanation:
Given that B is the midpoint of AC, then
AB = BC, that is
9x + 1 = 6x + 25 ( subtract 6x from both sides )
3x + 1 = 25 ( subtract 1 from both sides )
3x = 24 ( divide both sides by 3 )
x = 8
Hence
AC = AB + BC = 9x + 1 + 6x + 25 = 15x + 26, thus
AC = (15 × 8) + 26 = 120 + 26 = 146
Answer:
146
Step-by-step explanation:
AB = BC (Definition of midpoint) so:
9x+1=6x+25.
Solve it as you would any other algebraic equation >>> 9x+1=6x+25 >>> 9x+1-1=6x+25-1 >>> 9x=6x+24 >>> -6x+9x=6x-6x+24 >>> 3x=24 >>> 3x/3=24/3 >>> x=8
AB=9x+1 >>> AB=9*8+1 >>> AB=73
BC=6x+25 >>> BC=6*8+25 >>> BC=73
AC=AB+BC >>> AC=73+73 >>> AC=146
An online retailer charges $6.99 plus $0.55 per pound to ship electronics purchases. How many pounds is a DVD player for which the shipping charge is $11.94?
Answer:
[tex]9\ pounds[/tex]
Step-by-step explanation:
Let
x ----> the number of pounds of a DVD player
we know that
The number of pounds of a DVD player multiplied by the cost per pound ($0.55) plus the charge of $6.99 must be equal to $11.94
so
The linear equation that represent this situation is
[tex]0.55x+6.99=11.94[/tex]
solve for x
subtract 6.99 both sides
[tex]0.55x=11.94-6.99[/tex]
[tex]0.55x=4.95[/tex]

Find the indicated probability. Round to three decimal places. The participants in a television quiz show are picked from a large pool of applicants with approximately equal numbers of men and women. Among the last 11 participants there have been only 2 women. If participants are picked randomly, what is the probability of getting 2 or fewer women when 11 people are picked? 0.006 0.033 0.027 0.032
Answer:
0.033
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, p = 0.5, q = 0.5, and n = 11.
We need to find P when r is 0, 1, and 2, then add up the results to get the total probability.
r = 0:
P = ₁₁C₀ (0.5)⁰ (0.5)¹¹⁻⁰
P ≈ 0.0005
r = 1:
P = ₁₁C₁ (0.5)¹ (0.5)¹¹⁻¹
P ≈ 0.0054
r = 2:
P = ₁₁C₂ (0.5)² (0.5)¹¹⁻²
P ≈ 0.0269
Therefore, the total probability is:
P = 0.0005 + 0.0054 + 0.0269
P = 0.0328
Round to the thousandths place, the probability is 0.033.
Paul and Cindy own different pizza shops. Paul makes 12 pizzas the first day and 6 pizzas each day after that. Cindy makes 16 pizzas the first day and 4 pizzas each day after that. Who will have made more pizzas after 9 days? How many pizzas will that person have made?
A . Paul. He has made 80 pizzas after 9 days.
B . Cindy. She has made 132 pizzas after 9 days.
C. Paul. He has made 60 pizzas after 9 days.
D . Cindy. She has made 48 pizzas after 9 days.
Answer:
Paul. He has made 60 pizzas after 9 days.
Step-by-step explanation:
Paul makes 12 pizzas the first day and 6 pizzas each day after that.
So, after 9 days Paul will make total [12 + (9 - 1)6] = 60 pizzas.
Now, Cindy makes 16 pizzas the first day and 4 pizzas each day after that.
So, after 9 days Cindy will make total [16 + (9 - 1)4] = 48 pizzas.
Therefore, after 9 days Paul will make more pizzas and the number is 60 pizzas. (Answer)

Mary says 1/8 is
greater than 1/4 because 8 is greater than 4.
Is Mary's reasoning correct? Explain.
Answer:
No, Mary is incorrect. If you turn the fractions into decimals, 1/4 would be 0.25 and 1/8 would be 0.12½. Since 0.25 is greater than 0.12½, Mary is incorrect.
Mary's reasoning is incorrect because in fractions, the larger the denominator, the smaller the fraction's value, making 1/4 greater than 1/8.
Mary's reasoning that 1/8 is greater than 1/4 because 8 is greater than 4 is not correct. In the context of fractions, the larger the denominator (the bottom number), the smaller each part of the whole it represents. Thus, 1/4 is actually greater than 1/8 because dividing something into 4 parts results in larger parts than dividing it into 8 parts. This can be further understood by transforming both fractions into equivalent fractions with a common denominator or by converting them into decimal form (0.25 for 1/4 and 0.125 for 1/8) to directly compare their sizes.

What is the y-intercept of f(x)=8x^5-3x^3+12
The y intercept is (0, 12)
Solution:
Given function is:
[tex]f(x) = 8x^5 - 3x^3 + 12[/tex]
To find: y intercept
y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y
Substitute x = 0 in given function
[tex]f(0) = 8(0) -3(0) + 12[/tex]
y = 0 - 0 + 12
y = 12
Thus y - intercept is (0, 12)

Equation: y = 15x.
:)
Answer:
y = 15x
Step-by-step explanation:
The question asked, what equation shows the line through the data points. And it stated the equation needed to be in the form y = kx
Where
y represents the vertical axis
x represents the horizontal axis
k = constant
K is the constant interval and can be use to get the next points
y = kx
viewing the most visible points from the graph , let use the point where total saved is 90(y axis) and the time in weeks (x axis) is 6, the constant K can be gotten.
y = 90
x = 6
y = kx
90 = 6k
divide both sides by 6
k = 90/6
k = 15
Therefore,
y = 15x

6 Elizabeth bought 2 large bags of Doritos. She then spent $14 on soda. She spent a total
of $22. How much was each bag of Doritos?
Answer Statement:
Doritas Doritos
Answer: $4
Step-by-step explanation:
2d + 14 = 22
subtract 14
2d = 8
divide by 2
d = $4
each bag of Doritos costs $4
Elizabeth spent a total of $8 on 2 large bags of Doritos after spending $14 on soda, which means each bag costs $4.
Explanation:To determine the price of each bag of Doritos, we need to subtract the amount spent on soda from the total amount spent. Elizabeth spent $14 on soda and had a total of $22 in expenses. So, the money spent on Doritos is the difference between the total amount and the soda amount.
Amount spent on Doritos = Total amount - Amount spent on soda
Amount spent on Doritos = $22 - $14
Amount spent on Doritos = $8
Since Elizabeth bought 2 large bags of Doritos, we can find the price per bag by dividing the total amount spent on Doritos by 2.
Price per bag of Doritos = Total spent on Doritos / Number of bags
Price per bag of Doritos = $8 / 2
Price per bag of Doritos = $4 per bag
Therefore, each large bag of Doritos costs $4.
Create an equation where the solutions are 1/3 and 4 plus or minus i sqrt 7
Answer:
[tex] 3 {x}^{3} - 25 {x}^{2} + 35x - 23 = 0[/tex]
Step-by-step explanation:
We want to create an equation that will have the solution
[tex]x = \frac{1}{3},x = 4 + \sqrt{7}i,x = 4 - \sqrt{7}i[/tex]
This implies that:
[tex]3x -1= 0,x -( 4 + \sqrt{7}i) = 0,x - ( 4 - \sqrt{7}i) = 0[/tex]
We put the roots in factored form by reversing the zero product principle to get:
[tex](3x -1)(x -( 4 + \sqrt{7}i))(x - ( 4 - \sqrt{7}i)) = 0[/tex]
We expand the last two parenthesis to get:
[tex](3x - 1)( {x}^{2} - 4x + \sqrt{7}ix - 4x - \sqrt{7}ix + 16 - 7 {i}^{2}) = 0 [/tex]
We simplify to get:
[tex](3x - 1)( {x}^{2} - 8x + 23) = 0[/tex]
We expand further to obtain:
[tex]3 {x}^{3} - 25 {x}^{2} +35x - 23 = 0[/tex]

Lin is saving $300 per year in an account that pays 4.5% interest per year, compounded annually. How do I find the value after 20 years?
To find the value after 20 years, use the future value of a series formula with the given parameters, resulting in an approximate amount of $9,321.
Explanation:To find the value of $300 saved annually at 4.5% interest compounded annually after 20 years, we use the future value of a series formula:
FV = [tex]P * ((1 + r)^n - 1) / r[/tex]
Where:
FV = Future value of the seriesP = Yearly deposit ($300)r = Annual interest rate (4.5% or 0.045)n = Number of years (20)Substituting the given values:
FV = $300 * ((1 + 0.045)^20 - 1) / 0.045
= $300 * ((1.045)^20 - 1) / 0.045
= $300 * (2.398 - 1) / 0.045
= $300 * 1.398 / 0.045
= $300 * 31.07
= $9,321
Therefore, after 20 years, the value will be approximately $9,321.
Mrs. Kelly creates a garden. She buys 15 flowers and 3 bushes for a total cost of $160.32. Each bush costs $11.50 more than each flower. How much does each bush cost?
The cost of each bush is $ 18.49
Solution:Let "f" be the cost of each flower
Let "b" be the cost of each bush
Given that Mrs. Kelly buys 15 flowers and 3 bushes for a total cost of $160.32
15 flowers x cost of each flower + 3 bushes x cost of each bush = 160.32
[tex]15 \times f + 3 \times b = 160.32[/tex]
15f + 3b = 160.32 ----- eqn 1
Each bush costs $11.50 more than each flower
Cost of each bush = 11.50 + cost of each flower
b = 11.50 + f ------ eqn 2
Let us solve eqn 1 and eqn 2 to find values of "b" and "f"
Substitute eqn 2 in eqn 1
15f + 3(11.50 + f) = 160.32
15f + 34.5 + 3f = 160.32
18f = 160.32 - 34.5
18f = 125.82
f = 6.99Substitute f = 6.99 in eqn 2
b = 11.50 + 6.99 = 18.49
b = 18.49Thus the cost of each bush is $ 18.49
