Answer:
Step-by-step explanation:
Distributive property: a(b +c)=(a*b )+(a*c)
a) 2(y + 5x) = y*2 + 5x*2
= 2y + 10x
b) 0.4(x + 2) = x*0.4 + 2*0.4
= 0.4x + 0.8

find the slope of the line
Answer:
The slope of the line is: 1
Step-by-step explanation:
Use the equation
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Use the two sets of points given to you to slve the equation.
Assign the points their variables:
x1 y1 x2 y2
(4, 4) (8, 8)
Insert the numbers into the equation:
[tex] \frac{8 - 4}{8 - 4} [/tex]
Simplify:
[tex] \frac{4}{4} = 1[/tex]
Total world consumption of iron was approximately 900 million tons in 1993. If consumption had increased by 2.5% each year and the resources available for mining in 1993 were 450 billion tons, how much longer would the world’s iron resources have lasted?
Step-by-step explanation:
We can model the annual consumption of iron by the equation
c = 900 million tons x [tex]1.025^n[/tex], where
n is the number of years after 1993 and
c is the consumption for that year.
An estimate for the total consumption of iron can now be obtained by integrating this equation with respect to a dummy variable, x from 0 to n.
[tex]C = 900*10^6* \int\limits^n_0 {1.025^x} \, dx[/tex]
This equation simplifies to
C = 900 million tons x (1.025^n - 1) / ln(1.025), where
x is a dummy variable and
C is the total consumption of iron n years after 1993.
Let R be the amount of iron remaining at n years after 1993, so
R = 480 billion tons - C
R = 480 billion tons - 900 million tons x (1.025^n - 1) / ln(1.025)
We need to find the value of n when R is 0, so
0 = 480 billion tons - 900 million tons x (1.025^n - 1) / ln(1.025)
Simplify this equation to obtain
n = 107.4
So the iron will run out in the year 1993 + 107 = 2100

A population of 2000 fish increases at an annual rate of 7.5%. Write the model, then predict how
many fish will there be in 10 years?
Answer:
The model is [tex]P(t) = 2000(1.075)^{t}[/tex].
There will be 4122 fish in 10 years.
Step-by-step explanation:
Exponentially increasing population:
An exponentially increasing population can be represented by the following model:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(t) is the population after t years, P(0) is the initial population, and r is the growth rate, as a decimal.
A population of 2000 fish increases at an annual rate of 7.5%.
This means that [tex]P(0) = 2000, r = 0.075[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2000(1+0.075)^t[/tex]
[tex]P(t) = 2000(1.075)^{t}[/tex]
This is the model.
How many fish will there be in 10 years?
This is P(10).
[tex]P(t) = 2000(1.075)^{t}[/tex]
[tex]P(10) = 2000(1.075)^{10} = 4122[/tex]
There will be 4122 fish in 10 years.
Collectively, what are the interest costs and other fees for using a credit card called? A. balance B. credit line C. finance charge Reset Next
The correct answer is C. Finance charge
Explanation:
A credit card is a service offered by financial entities such as banks that allows customers to buy goods and pay them later. This implies the customer does not immediately for goods but pays for these after a specific time. The use of this benefit implies related costs such as fees for the use of the credit card, and interest costs (money charged for borrowing the money from the bank), which are known as finance charge or the money charged for the benefit of using credit. According to this, the correct answer is C.
Maribel is packing boxes of canned goods for the food drive. Each box can hold 8 books. How many boxes are needed for 122 books?
answer is:16 books
Answer:
16 boxes will be needed for 122 books.
Step-by-step explanation:
Given that,
Each box can hold 8 books.
We need to find the number of boxes needed for 122 books. It can be calculated as follows :
[tex]\dfrac{122}{8}[/tex] = 15.25
It means 15 boxes can be filled and 16 boxes will be needed for 122 books.
Ms. Ortiz borrows $2.50 every day for a school week (5 days) to buy a bacon egg and cheese. How much does
she owe by the end of the week? (Use negative numbers to show how much she owes
It’s multiplying signed numbers
Answer: She will owe $12.50 at the end of the week, and her account balance will be -12.50 dollars.
Step-by-step explanation:
A school week is 5 days. If Ms. Ortiz borrows $2.50 every day, then we will have to multiply 2.50 by 5 to find how much Ms. Ortiz owes at the end of the week.
2.50 x 5 = 12.5, or $12.50.
Therefore, Ms. Ortiz owes $12.50 at the end of the week, and her account balance will be -12.50.

a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.

(-2+6y+3x)(-3) distributive property to remove the parentheses
Answer:
6-18y-9x
Step-by-step explanation:
Using the textbook example of 420 California school districts and the regression of testscores on the student-teacher ratio, you find that the standard error on the slope coefficient is 0.51 when using the heteroskedasticity robust formula, while it is 0.48 when employing the homoskedasticity only formula. When calculating the t-statistic, the recommended procedure is to A. use the homoskedasticity only formula because the t-statistic becomes larger B. first test for homoskedasticity of the errors and then make a decision C. use the heteroskedasticity robust formula D. make a decision depending on how much different the estimate of the slope is under the two procedures
Answer:
The answer is "Option C".
Step-by-step explanation:
Robust standard errors or generic White-Huber mistakes depending on this procedure. This is also recognized as the Variance Sandwich Stimator because of the appearance of the formula. Therefore, which is under homoskedasticity, robust error terms were appropriate, in which the standard deviations of its predictor variables are non-constant and are tracked across different values or linked to pre-time periods of an exponential function.
Kevin earns $12.00 for every 5 story problems he writes. How much would Kevin get for writing 12 problems?
Answer: $28.80
Step-by-step explanation:
We can start by finding the unit rate. How much money does Kevin earn from writing 1 story problem?
We can find how much Kevin earns from writing 1 story by dividing 12 by 5.
12 ÷ 5 = 2.4.
Therefore, Kevin earns $2.40 for every story he writes.
Now we have to find how much Kevin earns from writing 12 story problems. If Kevin earns $2.40 for every story he writes, then we should mutliply that by 12 to find how much money Kevin earns for writing 12 problems.
2.40 x 12 = 28.8.
In conclusion, Kevin earns $28.80 dollars for writing 12 problems.

A penguin starts at 15 meters above sea level and ends at 7 meters below sea level. What is the change in elevation?
Answer:
22 meters
Step-by-step explanation:
If the penguin goes from 15 meters above sea level to sea level (0 meters), they traveled 15 meters in elevation.
Then they traveled another 7 meters when going 7 meters below sea level.
15 + 7 = 22
