A jet flies at an average speed of 230
miles per hour. How long will it take to
fly from New York to Amsterdam, a
distance of 3,647 miles? (distance =
rate time)
.
Answer:
15.9 hours.
Step-by-step explanation:
speed = distance / time.
230 = 3647 / time.
time = 3647 / 230.
time = 15.9 hours.
a local boys club sold 156 bags of mulch and made a total of $455 it's sold two types of mulch hard word for $3.25 a bag in Pine Box for $2.75 a bag how many bags of each kind did it sell
Let's define first the variables.
let H be the number of bags of the type that cost 3.25 and P the number of bags of the type that cost 2.75.
since they sold a total of 156 bags we have that H+P=156
and from the other condition we obtain 3.25H+2.75P=455
now we can solve the system of equations.
from the first equation H=156-P
substituing the previous equality in the second one we obtain:
[tex]3.25(156-P)+2.75P=455[/tex][tex]507-3.25P+2.75P=455[/tex][tex](2.75-3.25)P=-53[/tex][tex]0.5P=53[/tex][tex]P=106[/tex]now that we have P, we can replace it in the first equation obtaining that H=50
then the answer will be that they sold 50 bags of $3.25 and 106 bags of $2.75
Write the equation x2 + y2 + 6x + 8y + 24 = 0 in vertex form.
ANSWER
[tex](x+3)^2+(y+4)^2=1[/tex]EXPLANATION
We want to write the equation of the circle in vertex form:
[tex]x^2+y^2+6x+8y+24=0[/tex]The first step is to group the x terms and y terms together and take the constant to the right-hand side of the equality sign:
[tex]x^2+6x+y^2+8y=-24[/tex]Now, complete the square for the x terms:
[tex]\begin{gathered} x^2+6x+(\frac{6}{2})^2+y^2+8y=-24+(\frac{6}{2})^2 \\ x^2+6x+9+y^2+8y=-24+9 \\ (x+3)^2+y^2+8y=-15 \end{gathered}[/tex]Repeat the process for the y terms:
[tex]\begin{gathered} (x+3)^2+y^2+8y+(\frac{8}{2})^2=-15+(\frac{8}{2})^2 \\ (x+3)^2+y^2+8y+16=-15+16 \\ (x+3)^2+(y+4)^2=1 \end{gathered}[/tex]That is the equation of the circle in vertex form.

Consider the sample space of the following experiment:We roll two dice and each time we record numbers on both of them.How many elements are in the sample space?
Answer: 36
One die has a total outcome of 6 elements (1, 2, 3, 4, 5, 6). Now, if we roll two dice, each time you roll a number on the first die, there are another 6 possible outcomes for the second die.
Therefore, the number of elements in the sample space would be:

Suppose that Randy is an analyst for the bicyling industry and wants to estimate the asking price of used entry-level road bikes
advertised online in the southeastern part of the United States. He obtains a random sample of n = 14 online advertisements of
entry-level road bikes. He determines that the mean price for these 14 bikes is x = $714.19 and that the sample standard
deviation is s = $184.56. He uses this information to construct a 99% confidence interval for µ, the mean price of a used road
bike.
What is the lower limit of this confidence interval? Please give your answer to the nearest cent.
What is the upper limit of this confidence interval? Please give your answer to the nearest cent.
1. The lower limit of this confidence interval is $587.13.
2. The upper limit of this confidence interval is $841.25.
How are the lower and upper limits determined?The lower limit describes the lowest price that entry-level road bikes will cost.
The upper limit refers to the highest price that entry-level road bikes can command.
Using the lower and upper limits, Randy can confidently estimate the range of the asking price of the used entry-level road bikes.
N = 14
Mean price, µ = $714.19
Sample deviation = $184.56
Confidence interval = 99%
The z-score of 99% confidence interval = 2.576
The margin of error = z-score x (standard deviation/√n)
= 2.576 x ($184.56/√14)
= $127.06
Lower Limit = µ - margin of error
= $714.19 - $127.06
= $587.13
Upper Limit = µ + margin of error
= $714.19 + $127.06
= $841.25
Thus, Randy can estimate that the price of used entry-level road bikes is $714.19 ±$127.06 at a 99% confidence level.

Carson Company has an inventory turnover of 13.00, and its inventory amounts to $5,000,000. What is the amount of cost of goods sold?
$6,50,000 is the cost of the goods sold.
What is Inventory turnover?By dividing a company's cost of sales, or cost of goods sold, by its inventory turnover, one can determine how well it uses its inventory (COGS).
The number of times inventory is sold or used over a given time frame, like a year, is referred to as the inventory turnover in accounting. It is calculated to determine whether a company has an excessive amount of inventory in relation to its level of sales.
Inventory turnover is the count of times a company's stock is sold during the course of a month, a quarter, or (most frequently) a year of business.
We should apply the following formula to calculate the cost of goods sold:
Cost of goods sold / inventory equals inventory turnover.
Rearranging the equation and replacing the unknown values results in:
Inventory plus inventory turnover equals cost of goods sold.
Price of items sold = $5,000,000 divided by 13
$6,50,000 is the cost of the goods sold.

Problem
At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two small fries have a total of 1,330 calories. How many calories does each item contain?
Solution
For this case we can set up the following notation
x= number of cheeseburgers
y= small fries
4x +5y= 2310
3x + 2y= 1330
From the first equation we can solve for x and we got:
x= 577.5 - 5/4 y
And now we can replace this into the second equation and we got:
3(577.5 -5/4 y) +2y= 1330
And we can solve for y:
1732.5 - 15/4 y + 2y = 1330
-7/4 y = -402.5
y= 230 cal
And solving now for x we have:
x= 577.5 - 5/4 (230) = 577.5 - 287.5 = 290 cal

Calculate the standard score of the given X value, X=83, where μ=88.1 and σ=87. Round your answer to two decimal places.
The standard score for the given X value is -0.06
Standard Score
Standard score or Z - Score is inversely varies with the standard deviation and directly varies with the difference of the raw score and the mean score.
The formula to calculate standard score is
z - score = (X - μ)/σ
Where
Z = standard score
x = observed value
μ = mean of the sample
σ = standard deviation of the sample
Given,
Here we have the value of X = 83, μ=88.1 and σ=87.
Now, we need to find the standard score for this values and we have also round off the result to two decimal places.
Apply the given values on the z-score formula, then we get,
z-score = (83 - 88.1)/87
When we simplify the numerator, then we get,
z - score = -5.1/87
After the division of these numbers we get the value of z-score as,
z - score = -0.0586
When we round off the result into two decimal place then we get the value of standard score as -0.06.
