Maggie can do a job in 15 hours less than Ryan can. If they work together they can get the job done in 10 hours. How long would it take cach to do the job alone?
Maggie can do the job in
hours
Ryan can do the job in
hours
Answer:
Maggie = 15 hours
Ryan = 30 hours
Step-by-step explanation:
let x - time it takes Ryan to do the job alone.
x-15 - time it takes Maggie to do the job alone
[tex] \frac{10}{x} + \frac{10}{x - 15} = 1 \\ \\ \frac{10(x - 5) + 10x}{x(x - 15)} = 1[/tex]
[tex]10x - 150 + 10x = x {}^{2} - 15x \\ \\ 20x - 150 = x {}^{2} - 15x \\ \\ x {}^{2} - 15x - 20x + 150 = 0 \\ \\ x {}^{2} - 35x + 150 = 0 \\ \\ (x - 30)(x - 5) = 0 \\ \\ x = 30 \: and \: x - 15 = 15[/tex]
x = 5 --> not valid because x-15 will be NEGATIVE
Therfore,
Maggie can do the job in 15 hours.
Ryan can do the job in 30 hours.

A grocery store clerk put only packages of Takis and packages of Flamas on a shelf. The ratio of the number of packages of Flamas to the total number of packages on the shelf was 9 to 16.
Which number could be the number of packages of Takis the clerk put on the shelf?
Answer:
5 packages of Takis
Step-by-step explanation:
The total number packages that were placed on the shelf were 16 packages. The total number of packages of Flamas that were placed on the shelf were 9 packages. So to identify the number of packages of Takis the clerk put on the shelf, we simply do

Find all points on the x-axis that are 16 units from the point (4,-8)
Step-by-step explanation:
all points on the x axis have a y value of 0.
so, we need to find all points (x, 0) with a distance of 16 to (4, -8).
the distance to a point is the Hypotenuse of the right-angled triangle with the coordinate differences as legs.
and so Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (side opposite of the 90° angle).
so, in our case we have
16² = (4-x)² + (-8 - 0)²
256 = 16 - 8x + x² + 64 = x² - 8x + 80
x² - 8x - 176 = 0
if we have no other idea of factorization the general solution of such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -8
c = -176
x = (8 ± sqrt((-8)² - 4×1×-176))/(2×1) =
= (8 ± sqrt(64 + 704))/2 = (8 ± sqrt(768))/2 =
= (8 ± sqrt(256×3))/2 = (8 ± 16×sqrt(3))/2 =
= 4 ± 8×sqrt(3)
x1 = 4 + 8×sqrt(3) = 17.85640646...
x2 = 4 - 8×sqrt(3) = -9.856406461...
so, the points on the x axis that are 16 units apart from (4, -8) are
(x1, 0) and (x2, 0)
I am not sure in what format you need the answer.
please fill in for x1 and x2 from above what you need.
suppose there is a normally distributed population with a mean of 250 and a standard deviation of 50. if xbar is the average of a sample of 36, find P(246
Using the normal distribution and the central limit theorem, it is found that:
[tex]P(246 \leq \bar{x} \leq 260) = 0.5693[/tex]
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of [tex]\mu = 250[/tex].The standard deviation is of [tex]\sigma = 50[/tex].A sample of 36 is taken, hence [tex]n = 36, s = \frac{50}{\sqrt{36}} = 8.3333[/tex].The probability of a sample mean between 246 and 260 is the p-value of Z when X = 260 subtracted by the p-value of Z when X = 246, hence:
X = 260:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{260 - 250}{8.3333}[/tex]
[tex]Z = 1.2[/tex]
[tex]Z = 1.2[/tex] has a p-value of 0.8849.
X = 246:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{246 - 250}{8.3333}[/tex]
[tex]Z = -0.48[/tex]
[tex]Z = -0.48[/tex] has a p-value of 0.3156.
0.8849 - 0.3156 = 0.5693, hence:
[tex]P(246 \leq \bar{x} \leq 260) = 0.5693[/tex]

Find the height of a cone with a diameter of 12 m whose volume is 340 m2
Use 3.14 for tr and round your answer to the nearest meter.
12 m
A. 28 m
O B.2 m
O C. 12 m
O D. 9m
Answer:
h = 9 m
Step-by-step explanation:
[tex]V_{cone}=340\: m^3[/tex]
diameter (d) = 12 m
[tex]\implies radius\:(r)= \frac{12}{2}=6\:m[/tex]
[tex] \because \: V_{cone}= \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: h = \frac{3V_{cone}}{\pi {r}^{2} } \\ \\ \implies \: h = \frac{3(340)}{3.14 {(6)}^{2} } \\ \\ \implies \: h = \frac{1020}{113.04} \\ \\ \implies \: h = 9.02335456 \\ \\ \implies \: h \approx 9 \: m[/tex]

The price of an all-access ticket to the fair is $42.99 before tax. Roland bought the all-access ticket for 40% off. He then paid 7% sales tax on the discounted price. Part A: How much did Roland pay in sales tax? Show all work and steps in your solution. (5 points) Part B: What is the total amount that Roland paid for the ticket? Show all work and steps in your solution.
Answer:
See below
Step by step explanation:
Here it is given that , the price of a ticket is $42.99 before tax . And he got a discount of 40% . So the cost after discount will be ,
[tex]\longrightarrow Cost = \$ 42.99 - \$42.99\times \dfrac{40}{100} \\[/tex]
Simplify ,
[tex]\longrightarrow Cost = \$ 42.99 - \$17.196 \\[/tex]
[tex]\longrightarrow Cost = \$ 25.79 [/tex]
Again it is given that he paid a tax of 7% on the discounted price . So the tax paid in dollars will be ,
[tex]\longrightarrow Tax = 7\% \ of \ \$25.79\\ [/tex]
Simplify ,
[tex]\longrightarrow Tax = \dfrac{7}{100}\times \$ 25.79 [/tex]
[tex]\longrightarrow \underline{\underline{ Tax =\$ 1.80 }} [/tex]
Answer of Part A : He paid a sales tax of $1.80 .
Now the total amount paid can be calculated by adding sales tax to the cost after discount .
[tex]\longrightarrow Total\ Amount = \$ 25.79 +\$ 1.80\\ [/tex]
Add ,
[tex]\longrightarrow \underline{\underline{ Total \ Amount = \$ 27.59}} [/tex]

Answer:
165 yd (nearest yard)
Step-by-step explanation:
To calculate the distance from the ball to the center of the green, we need to use the cosine rule:
[tex]c^2=a^2+b^2-2ab \cos (C)[/tex]
where:
C is the anglea and b are the sides adjacent to the angle Cc is the side opposite the angle CTherefore, for this triangle:
a = 35 ydb = 150 ydC = 110°Substituting these values into the cosine rule formula:
[tex]\implies c^2=35^2+150^2-2(35)(150) \cos (110\textdegree)[/tex]
[tex]\implies c^2=23725-10500\cos(110\textdegree)[/tex]
[tex]\implies c=\sqrt{23725-10500 \cos(110\textdegree)}[/tex]
