Answers:
11) D. $3012) Two answers: choice C, choice D13) A. Subtract 100 from each side14) A. n = 9 and n = -5====================================================
Explanation:
11) We set p(120-4p) equal to zero to find that p = 0 is one solution and 120-4p = 0 leads to p = 30. The prices of $0 and $30 both lead to $0 in revenue. It sounds like your teacher wants the larger price value.12) We set each of the two revenue expressions equal to 600.13) Replace the (n-2)^2 with another variable. Let's call that x. So we have the equation 100+x = 149, which is the same as x+100 = 149. We subtract 100 from both sides to undo the +100.14) After following the steps in problem 13, you should have (n-2)^2 = 49, which then becomes n-2 = 7 or n-2 = -7 after applying the square root to both sides. Those two equations solve to n = 9 and n = -5 in that order.help me pls!!!!!!!!!!

Answer:
V=[tex]\frac{28\pi }{3}[/tex]
Step-by-step explanation:
Plug and chug into the formula, your radius is 2ft, and your height is 7ft.
[tex]V=\pi*2^{2} *\frac{7}{3}[/tex]
V=[tex]\frac{28\pi }{3}[/tex] or 29.30 if [tex]\pi =3.14[/tex]
The width of a picnic table is 3 times its length. If the length is 5/6 yd long, what is the area of the picnic table in square feet?
Step-by-step explanation:
Breadth
=5/6
Length
=15/6
Area of rectangle = l x b
=5/6 x 15/6
=75/6
Answer:
6 1/4 sq ft
Step-by-step explanation:
x = length = 5/6
y = width = 3x
so y = 3(5/6) or 15/6
A = length · width
A = 5/6 · 15.6 or 25/12 which is 6 1/4
Ariana compró cierto número de sacos de azúcar por S/. 675 y luego los vendió por S/. 1 080, ganando S/. 3 por cada saco. ¿Cuántos sacos de azúcar compró?
Responder:
135
Explicación paso a paso:
Número de bolsas compradas = x
Costo total de compra = 675
Costo total de ventas = 1080
Beneficio por bolsa = 3
Por eso :
Beneficio total + costo total de compra = costo total de ventas
3x + 675 = 1080
3x = 1080 - 675
3 veces = 405
x = 405/3
x = 135
Se compraron 135 bolsas
On a map of Arizona 2 inches represents 54 miles. The map distance from Yuma to Sentinel is 3 inches. What is the actual distance in miles between the cities?
Answer: 81 miles
Step-by-step explanation:

Last week, Thomas ran 5 1/4 miles. This week, he planes to run 1/2 as far as he ran last week. How many miles does Thomas plan to run this week?
Answer:
2.625
Step-by-step explanation:
Last week Thomas ran 5 1/4 miles
This week he plans to run 1/2 miles as far
Therefore the number of miles he plans to run cann be calculated as follows
= 5 1/4 × 1/2
= 21/4 × 1/2
= 21/8
= 2.625
Hence Thomas plans to run 2.625 miles

A. 104.5%
B. 95.5%
C. 4.5%
D. 0.045%
Answer:
Michael starts a website for people in his town to share news and photos. Before launching the website, he has his friends and family sign up. Then, he uses the equation shown below to estimate the number of user, y, who will have signed up x weeks after he officially launches the website.
y = 82(1.045)x
What is the rate of growth Michael expects each week after launching the website?
The answer will be %0.045
Step-by-step explanation:
The rate of growth Michael expects each week after launching the website is 4.5%.
Given that,
The function is y = 82 (1.045)x.We need to find the rate of growth.Based on the above information, the calculation is as follows:
Since 1.045 is given so this means 4.5% is the growth rate.
Therefore we can conclude that the rate of growth Michael expects each week after launching the website is 4.5%.

In a recent year, a hospital had 4310 births. Find the mean number of births per day, then use that result and the Poisson Distribution to find the probability that in a day there are 13 births.
Answer:
11.8 ;
0.1036360
Step-by-step explanation:
Mean births per day, μ = number of births per year / number of days in a year ;
4310 / 365 = 11. 8 births per day
From poisson distribution :
P(x) = (μ^x * e^-μ) ÷ x!
P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!
P(x = 13) = 6.453438E8 / 13!
P(x = 13) = 0.1036360

Hey There!
So the rule about interior angles of a trapezoid
is that the angles that lie on the segments that are not parallel are supplements
so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do
180=15x+8+7x-4
step 1 combine like terms
15+7=22
8-4=4
now we have
180=22x+4
step 2 subtract 4 from each side
180-4=176
now we have
176=22x
step 3 divide each side by 22
176/22=8
so x=8
now we plug in 8 to 15x+8
8x15=120
120+8=128
so we can conclude that angle R = 128

During a building project, a brick is
dropped from a height of 1,936 ft. If the
equation for height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the brick to
hit the ground?
[?] seconds
Answer:
11 seconds
Step-by-step explanation:
h(t) = -16t^2 + 1936
When the brick hits the ground h = 0 so:
-16t^2 + 1936 = 0
-16t^2 = -1936
t^2 = -1936/-16
= 121
t = 11 seconds.
The amount of time taken by the brick to hit the ground is 11 seconds.
What is a function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
It is given that during a building project, a brick is dropped from a height of 1,936 ft. If the equation for height as a function of time is h(t) = -16t² + initial height. where t is time in seconds and h(t) is height in feet.
h(t) = -16t² + 1936
When the brick hits the ground h = 0 then the amount of time taken by the brick will be calculated as below:-
-16t² + 1936 = 0
-16t² = -1936
t² = -1936/-16
t²= 121
t = 11 seconds.
Therefore, the amount of time taken by the brick to hit the ground is 11 seconds.
