At a baseball game, a vender sold a combined total of 114 sodas and hot dogs. The number of hot dogs sold was 30 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answer:
Sodas: 72
Hotdogs: 42
Step-by-step explanation: First you take 114 and subtract 30 from it since there are 30 more sodas. You then would take the remaining 84, and divide it between the two giving you 42 hotdogs and 42 sodas. Now remember the 30 we had? Youre gonna add that to the 42, giving you 72 sodas and 42 hotdogs.

Find the point P that is 2/5 of the way from A to B on the directed line segment AB if A (-8, -2) and B (6, 19).
The coordinates of point P, which is 2/5 of the way from A to B on the directed line segment AB, are approximately (-12/5, 32/5).
To find the point P that is 2/5 of the way from A to B on the directed line segment AB, we can use the following formula:
P = A + (2/5) * (B - A)
Given:
A = (-8, -2)
B = (6, 19)
Let's calculate the coordinates of point P:
P = (-8, -2) + (2/5) * ((6, 19) - (-8, -2))
P = (-8, -2) + (2/5) * (14, 21)
P = (-8, -2) + (28/5, 42/5)
P = (-8 + 28/5, -2 + 42/5)
P = (-40/5 + 28/5, -10/5 + 42/5)
P = (-12/5, 32/5)
Therefore, the coordinates of point P, which is 2/5 of the way from A to B on the directed line segment AB, are approximately (-12/5, 32/5).

Professor Zsolt Ugray lives in Boston and is planning his retirement. He plans to move to Florida and wants to buy a boat. The boat he is buying is a "2007 Sea Ray 340 Sundancer" (see image).
Using your Excel skills and understanding of financial functions, you're helping Prof. Ugray assess the impact of this loan on his finances. To buy this boat, Prof. Ugray will get a large Loan ($150,000) and pay $1,770 monthly during 10 years.
Calculate below:
- The monthly rate for this loan
- The annual rate for this loan
- The effective annual rate for this loan
- Total Amount Paid After 10 Years
- The Future value for this loan.
The monthly rate for the given loan is 1.0118%.The annual rate for this loan is 12.1423%.
Given loan: $150,000
Payment per month: $1,770
Duration of loan: 10 years
Interest = ?
The formula for monthly payment is given by:
\(PV = pmt x (1 - (1 + r)^-n) / r\)
Where, PV is the present value, pmt is the payment per period, r is the interest rate per period and n is the total number of periods.Solving the above formula for r will give us the monthly rate for the loan.
r = 1.0118%The monthly rate for the given loan is 1.0118%.The annual rate can be calculated using the following formula:
Annual rate = \((1 + Monthly rate)^12 - 1\)
Annual rate = 12.1423%
The annual rate for this loan is 12.1423%.The effective annual rate can be calculated using the following formula:
Effective annual rate =\((1 + r/n)^n - 1\)
Where, r is the annual interest rate and n is the number of times interest is compounded per year.If interest is compounded monthly, then n = 12
Effective annual rate = (1 + 1.0118%/12)^12 - 1
Effective annual rate = 12.6801%
The effective annual rate for this loan is 12.6801%.
Total amount paid after 10 years = Monthly payment x Number of payments
Total amount paid after 10 years = $1,770 x 120
Total amount paid after 10 years = $212,400
The total amount paid after 10 years is $212,400.
The future value for this loan can be calculated using the following formula:
FV = PV x (1 + r)^n
Where, PV is the present value, r is the interest rate per period and n is the total number of periods.If the loan is paid off in 10 years, then n = 120 (12 payments per year x 10 years)
FV = $150,000 x (1 + 1.0118%)^120
FV = $259,554.50
The future value for this loan is $259,554.50.
Thus, the monthly rate for the loan is 1.0118%, the annual rate for this loan is 12.1423%, the effective annual rate for this loan is 12.6801%, the total amount paid after 10 years is $212,400 and the future value for this loan is $259,554.50.

suppose that x is the number of cars per minute that pass through a certain intersection, and that x has the poisson distribution. what can be the smallest value of x? enter your answer in accordance to the question statemententer your answer in accordance to the question statement
The smallest value of x in the Poisson distribution is 0, which means that no cars can pass through the intersection in a given minute.
For explain further, a Poisson distribution is a statistical model that describes the probability of a given number of events occurring in a fixed period of time, such as cars passing through an intersection in a minute.
In a Poisson distribution, the probability of x events occurring in a given minute is given by the equation P(x) = e-λλx/x!, where λ is the average number of events in a given minute. In this case, λ would be the average number of cars that pass through the intersection per minute.
The probability of 0 cars passing through the intersection in a given minute is e-λλ0/0! = 1, which is the highest probability in the distribution. Therefore, the smallest value of x in a Poisson distribution is 0.

A lilly pond starts with 1 lilly pad and every day the amount doubles. how many lilly pads are in the pond after d days
After d days, the number of lily pads in the pond can be calculated using the formula 2^d. So, if d is the number of days, then the number of lily pads after d days would be 2^d.
Each day, the number of lily pads doubles. So, on the first day, there is 1 lily pad. On the second day, the number doubles to 2. On the third day, it doubles again to 4, and so on. This doubling pattern continues for d days.
To calculate the number of lily pads after d days, we raise 2 to the power of d (2^d). This is because each day, the number of lily pads doubles, which can be represented as 2^1, 2^2, 2^3, and so on. By substituting the value of d into the equation, we can find the number of lily pads after d days.
For example, if d = 5, then the number of lily pads after 5 days would be 2^5 = 32. This means that there would be 32 lily pads in the pond after 5 days.

13. Calculate the compound interest of an annuity due of BD400 paid each 4 months for 6.2 years if the nominal rate is 3% thirdly? (3 Points)
Therefore, the compound interest of the annuity due of BD 400 paid each 4 months for 6.2 years at a nominal rate of 3% per annum is BD 40,652.17.
Compound interest of an annuity due can be calculated using the formula:A = R * [(1 + i)ⁿ - 1] / i * (1 + i)
whereA = future value of the annuity dueR = regular paymenti = interest raten = number of payments First, we need to calculate the effective rate of interest per period since the nominal rate is given per annum. The effective rate of interest per period is calculated as
:(1 + i/n)^n - 1 = 3/1003/100 = (1 + i/4)^4 - 1
(1 + i/4)^4 = 1.0075i/4 = (1.0075)^(1/4) - 1i = 0.0303So,
the effective rate of interest per 4 months is 3.03%.Next, we can substitute the given values in the formula:
A = BD 400 * [(1 + 0.0303)^(6.2 * 3) - 1] / 0.0303 * (1 + 0.0303)A = BD 400 * [4.227 - 1] / 0.0303 * 1.0303A = BD 400 * 101.63A = BD 40,652.17

I just need some help with the math for this 3-part problem.
Data for this question. A 180-cm3 soil sample was collected three days after a drenching rain when
the soil was assumed to be at field capacity (Not Saturated!). The wet weight of the sample was 274.1 g
and after drying overnight in an oven the sample weighed 214.7 g.
1. What was the gravimetric moisture content of this soil at field capacity?
1a. What is the dry bulk density of this sample?
1b. What is the porosity of this sample as a percent of the total volume?
1) The gravimetric moisture content of the soil at field capacity is approx 27.62%.
2) The dry bulk density of the sample is approximately 1.193 g/cm^3.
3) The porosity of the sample, as a percentage of the total volume, is approximately 54.96%.
1) The gravimetric moisture content of the soil at field capacity can be calculated using the following formula:
Gravimetric Moisture Content = ((Wet Weight - Dry Weight) / Dry Weight) * 100
Given:
Wet Weight = 274.1 g
Dry Weight = 214.7 g
Using the formula, we can substitute the values:
Gravimetric Moisture Content = ((274.1 - 214.7) / 214.7) * 100
Gravimetric Moisture Content = (59.4 / 214.7) * 100
Gravimetric Moisture Content ≈ 27.62%
The gravimetric moisture content of the soil at field capacity is approximately 27.62%.
The gravimetric moisture content represents the amount of water present in a given mass of soil. By subtracting the dry weight of the soil from the wet weight and dividing by the dry weight, we can determine the proportion of water in the sample. Multiplying by 100 gives the moisture content as a percentage.
1a. The dry bulk density of the sample can be calculated using the following formula:
Dry Bulk Density = Dry Weight / Sample Volume
Given:
Dry Weight = 214.7 g
Sample Volume = 180 cm^3
Substituting the values into the formula:
Dry Bulk Density = 214.7 g / 180 cm^3
Dry Bulk Density ≈ 1.193 g/cm^3
The dry bulk density of the sample is approximately 1.193 g/cm^3.
Dry bulk density refers to the mass of dry soil per unit volume. To calculate it, we divide the dry weight of the soil by the sample volume.
1b. The porosity of the sample can be calculated using the following formula:
Porosity = (1 - (Dry Bulk Density / Particle Density)) * 100
The particle density for soil is usually around 2.65 g/cm^3.
Given:
Dry Bulk Density = 1.193 g/cm^3
Particle Density = 2.65 g/cm^3
Substituting the values into the formula:
Porosity = (1 - (1.193 / 2.65)) * 100
Porosity ≈ 54.96%
The porosity of the sample, as a percentage of the total volume, is approximately 54.96%.
Porosity represents the void space within a soil sample. It is calculated by subtracting the ratio of the dry bulk density to the particle density from 1 and multiplying by 100 to get the percentage. In this case, the particle density of 2.65 g/cm^3 is a typical value for soil.

Refer to the graphic novel frame below. The brochure says that the rope is 500 feet long. Jacob drew a triangle in the sand that is similar to the actual triangle formed by a parasailer and the boat. Use the properties of similar triangles to determine the parasailer's height above
To solve this problem use the property of similar triangles,
"Corresponding sides of the similar triangles are proportional"
By using this property, height of the parasailer is 160 feet.
From the figure attached,
In ΔPQR, a parasailer is a at point P and a boat is at R.Actual length of the rope PR = 500 ftJacob drew a similar triangle ABC in which parasailer is at A and the boat is at C.Let the height (PQ) of the parasailer = x ft
Height of the parasailer AB = 25 ft.
And the length of the rope AC = 2.5 ft.
Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.
\(\frac{AB}{PQ}=\frac{AC}{PR}\)
\(\frac{2}{x} =\frac{2.5}{200}\)
\(x=\frac{200\times 2}{2.5}\)
\(x=160\) ft
