Kelly is 5'4" tall. She measured her shadow one morning to be 8'7". She then measured the shadow of her house. The house shadow was 42'3". How tall is the
actual house? (inches rounded to the hundredths.)
The height of the actual house is 26'.26" .
How to find the height of the house using ratio?A ratio indicates how many times one number contains another.
Therefore, the heights will form a similar length. Therefore, the corresponding length have the same ratios.
Therefore,
height of Kelly / x = height of Kelly shadows / height of house shadow
Hence,
where
x = actual height of the house
5.4 / x = 8.7 / 42.3
cross multiply
42.3 × 5.4 = 8.7x
Therefore,
228.42 = 8.7x
divide both sides by 8.7
228.42 / 8.7 = 8.7x / 8.7
x = 26.2551724138
Therefore, the height of the actual house is 26'.26"

Se vendieron un total de 430 boletos para la obra de teatro escolar. Los boletos eran o de adulto o de estudiante. Se vendieron 70 boletos de estudiante menos que boletos de adulto. ¿Cuántos boletos de adulto fueron vendidos?
Resolviendo un sistema de ecuaciones, veremos que se vendieron 250 boletos de adulto.
¿Cuántos boletos de adulto fueron vendidos?
Definamos las variables:
x = boletos de adulto vendidos.y = boletos de estudiantes vendidos.Se vendieron un total de 430 boletos, entonces:
x + y = 430
Y se vendieron 70 boletos de estudiante menos que boletos de adulto:
y = x - 70
Tenemos el sistema de ecuaciones:
x + y = 430
y = x - 70
Para resolverlo, podemos reemplazar la segunda ecuación en la primera:
x + y = 430
x + (x - 70) = 430
2x = 430 + 70 = 500
x = 500/2 = 250

a group of young women decided to raise 480000 to start a business after some time 4 women pulled outand they had to pay additional 20000 . determine the original number of women
Answer:
96 is the number of original women investors.
Step-by-step explanation:
Let X be the number of young women in the initial group. They raised 480000, so the average payment per person was (480000/X).
When 4 pull out, the new average is (480000/(X-4)). We are told that this new average required the remaining women (X-4) to add another 20000.
The four women therefore had contributed 20000 in total, making their average 20000/4 = 5000 each.
This would have been the same amount contributed by all X women. Thus, we can set the average (480000/X) equal to 5000
(480000/X) = 5000
(480000) = 5000X
(480000)/5000 = X
X = 96
The original number of women was 96.
===
Check
(96 Women)(5000/Woman) = 480000 CHECKS
(4 Women pull out)*(5000) = 20000 that needs to be added to stay at 480000. CHECKS

what is the volume of the sphere shown below with a radius of 9
Answer:
972π or 3052.08 if π=3.14(remember to label the answer with your units)
Step-by-step explanation:
The formula for the volume of a sphere is [tex]\frac{4}{3}\\[/tex]π[tex]r^{3}[/tex]. So, just plug the radius into the formula. [tex]r^{3}[/tex] in this case is [tex]9^{3}[/tex] which is 729. For, [tex]\frac{4}{3}[/tex]×729, the 3 and 729 cancel out to create 4×243 which is 972. Just add π to this and you get 972π. If π is 3.14 just multiple 972 and 3.14 to get 3052.08.
Use the drop-down menus to complete the proof. by the unique line postulate, you can draw only one segment,
The reflection of BC over I is shown below.
What is reflection?A reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is known as the reflection's axis (in dimension 2) or plane (in dimension 3). A figure's mirror image in the axis or plane of reflection is its image by reflection.See the attached figure for a better explanation:
1. By the unique line postulate, you can draw only one line segment: BC
Since only one line can be drawn between two distinct points.2. Using the definition of reflection, reflect BC over l.
To find the line segment which reflects BC over l, we will use the definition of reflection.3. By the definition of reflection, C is the image of itself and A is the image of B.
Definition of reflection says the figure about a line is transformed to form the mirror image. Now, the CD is the perpendicular bisector of AB so A and B are equidistant from D forming a mirror image of each other.4. Since reflections preserve length, AC = BC
In Reflection the figure is transformed to form a mirror image.Hence the length will be preserved in case of reflection.Therefore, the reflection of BC over I is shown.

Firm valuation schultz industries is considering the purchase of arras manufacturing. arras is currently a supplier for schultz, and the acquisition would allow schultz to better control its material supply. the current cash flow from assets for arras is $8 million. the cash flows are expected to grow at 9 percent for the next five years before leveling off to 6 percent for the indefinite future. the cost of capital for schultz and arras is 13 percent and 11 percent, respectively. arras currently has 3 million shares of stock outstanding and $25 million in debt outstanding. what is the maximum price per share schultz should pay for arras? (do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) price per share $
Based on the calculations, the maximum price per share that Schultz should pay for Arras is approximately equal to $53.00.
How to calculate the maximum price per share?First of all, we would determine the cash flows for the company until the growth rate changes at a constant perpetual rate:
Year 1: $8,000,000(1 + 0.09) = $8,720,000.
Year 2: $8,720,000(1 + 0.09) = $9,504,800.
Year 3: $9,504,800(1 + 0.09) = $10,360,232.
Year 4: $10,360,232(1 + 0.09) = $11,292,652.88.
Year 5: $11,292,652.88(1 + 0.09) = $12,308,991.6392.
Year 6: $12,308,991.6392(1 + 0.06) = $13,047,5311.137552.
Next, we would calculate the terminal value in Year 5:
TV₅ = CF₆/(RWACC - g)
TV₅ = CF₆/(0.11 - 0.06)
TV₅ = $12,308,991.6392/0.05
TV₅ = $246,179,832.784.
By using Arras' cost of capital, we would determine its present value:
V₀ = $8,720,000/(1 + 0.11) + $9,504,800/(1 + 0.11)² + $10,360,232/(1 + 0.11)³+ $11,292,652.88/(1 + 0.11)⁴+ ($12,308,991.6392 + $246,179,832.784)/(1 + 0.11)⁵.
V₀ = $8,720,000/(1.11) + $9,504,800/(1.11)² + $10,360,232/(1.11)³+ $11,292,652.88/(1.11)⁴+ ($12,308,991.6392 + $246,179,832.784)/(1.11)⁵.
V₀ = 7,855,855.8559 + 7,714,308.9035 + 7,575,312.3467 + 7,438,820.2323 + 153,400,536.1422.
V₀ = $183,984,855.4806.
For the market value of the equity, we have:
S = 183,984,855.4806 - 25,000,000
S = $158,984,855.4806.
Now, we can find the maximum price per share:
Maximum price per share = 158,984,855.4806/3,000,000
Maximum price per share = $52.9949 ≈ $53.00.

What is a linear equation in math?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.I spent a dollars at American Eagle, which is 4 more than the amount I spent at Banana Republic ( b ).
a = b + 4. Therefore: b = a - 4
Also I spent 15 less at American Eagle than I spent in Cole Haan ( c ).
a = c - 15, or: c = a + 15.
75 - a - ( a - 4 ) - ( a + 15 ) = 75 - a - a + 4 - a - 15 =

So since 18 chose to do oral report, that means (28-18) or 10 students decided to do a written report.
To find the written to oral report ration, we need to find for each student that did a written report, how many did an oral report? We can express this as a fraction and simplify to get the simplified ratio. So the the written will be the numerator and the oral will be the denominator: 10/18, to simplify this simply divide both sides by 2, to get 5/9 which gives us the simplified ratio of 5:9 meaning that for every 5 students who decided to do a written report 9 students decided to do an oral report.
