Answer:
x + y = 87
1.5x + 0.5y = 78.50
Step-by-step explanation:
Let x be the number of nachos sold and y be the number of sodas sold
x nachos will cost 1.50x dollars
y sodas will cost 0.50y dollars
So total sales = 1.5x + 0.5y and we know he made $78.50
so one equation is
1.5x + 0.5y = 78.50
Total sold = x + y and we know that this number is 87
So the second equation is
x + y = 87

Express the following numbers in scientific notation
Answer:
To express a number in scientific notation, you need to write it as a number between 1 and 10, multiplied by a power of 10.
In this case, 367 can be written as 3.67 x 100, and 10-3 can be written as 0.001.
Therefore, 367 x 10-3 can be expressed in scientific notation as:
3.67 x 0.001 = 0.00367
This can also be written as 3.67 x 10^-3. The ^ symbol indicates an exponent, and in this case, it means that the base number (3.67) is multiplied by 10 to the power of -3.

The equation of the circle described in the problem is x² + (y - 8)² = 64.
What is the equation of a circle?
The general equation of any type of circle is represented by: x2 + y2 + 2gx + 2fy + c = 0, for all values of g, f, and c.
The general equation of a circle is (x – h)2 + (y – k)2 = r2, where (h, k) represents the location of the circle's center, and r represents the length of its radius.
The standard form equation of a circle with center at (h, k) and radius r is given by:
(x - h)² + (y - k)² = r²
Substituting the given values into this equation, we get:
(x - 0)² + (y - 8)² = (8)²
Simplifying this equation gives:
x² + (y - 8)² = 64

Consider the following general triangle.
C = 60.0°, c = 151 m, b = 181 m
(a)
Determine the number of solutions.
(b)
Solve the triangle, if possible, using the labels as shown in the figure below. (Round lengths in m to three significant digits and angles to the nearest tenth of a degree. If there is no solution, enter NO SOLUTION in all unused answer blanks. If there is more than one solution, enter your answers as a comma-separated list.)
A °=
B °=
a=
To solve this problem, we can use the Law of Cosines. The Law of Cosines states that for a triangle with sides a, b, and c and the angle C opposite side c, the following equation holds:
c^2 = a^2 + b^2 - 2abcos(C)
In this problem, we are given the measure of angle C and the lengths of sides b and c. We can use this information to find the length of side a and the measures of angles A and B.
First, we can use the Law of Cosines to find the length of side a. Plugging in the given values, we get:
a^2 = c^2 - b^2 + 2bc cos(C)
Substituting in the given values, we get:
a^2 = 151^2 - 181^2 + 2 * 151 * 181 * cos(60.0°)
Solving this equation gives us a = 143 m.
Now that we have the length of side a, we can use the Law of Sines to find the measures of angles A and B. The Law of Sines states that for a triangle with sides a, b, and c and angles A, B, and C opposite these sides, the following equation holds:
a/sin(A) = b/sin(B) = c/sin(C)
We are given the lengths of sides a and b and the measure of angle C. We can use this information to find the measures of angles A and B.
First, we can use the Law of Sines to find the measure of angle A. Plugging in the given values, we get:
a/sin(A) = b/sin(B)
Solving for sin(A), we get:
sin(A) = a * sin(B) / b
Substituting in the given values, we get:
sin(A) = 143 m * sin(B) / 181 m
To find the measure of angle A, we can use the inverse sine function (sin^-1). This gives us:
A = sin^-1(sin(A))
= sin^-1(143 m * sin(B) / 181 m)
Similarly, we can use the Law of Sines to find the measure of angle B:
B = sin^-1(143 m * sin(A) / 181 m)
Since we have two unknowns (A and B) and two equations, there is a unique solution for this triangle.
Therefore, the number of solutions is 1, and the measures of angles A and B are A = 38.5° and B = 101.5°. The length of side a is 143 m.

In 2012, the population of a city was 6.51 million. The exponential growth rate was 2.75% per year. a) Find the exponential growth function. b) Estimate the population of the city in 2018. c) When will the population of the city be 10 million? d) Find the doubling time.
The exponential growth function is P = 6.51 (1.0275)^t. The population of the city in 2018 will be 7.66 million. The population of the city will be 10 million in 15.82258467 years and the doubling time is 25.55035862 years
How to find the exponential growth function?The exponential growth function is of the form P = P₀(1+r)^t
where P₀ is the current population, r is the growth rate and t is the time
Given: P₀ = 6.51 million, r = 2.75% per year
a) The exponential growth function
P = 6.51 (1+0.0275)^t
P = 6.51 (1.0275)^t
b) The population of the city in 2018
t = 2018-2012 = 6 years
P = 6.51 (1.0275)^t
P = 6.51 (1.0275)⁶ = 7.66 million
c) When the population of the city will be 10 million
P = 6.51 (1.0275)^t
10 = 6.51 (1.0275)^t (Solve for t)
(1.0275)^t =10/6.51
log (1.0275)^t = log(10/6.51)
t × log (1.0275) = log(10/6.51)
t = [log(10/6.51)] / [log (1.0275)]
t = 15.82258467 years
d) The doubling time
P = 6.51 (1.0275)^t will become:
2 = 1 (1.0275)^t
1.0275^t = 2
log(1.0275)^t = log 2
t log(1.0275) = log 2
t = log 2 / log 1.0275
t = 25.55035862 years

How far does a wheel travel in 4 rotations with a radius of 36 inches?
Round to the nearest hundredths
The wheel will travel 904.32 inch when it take 4 rotation
How do you calculate distance using radius and revolutions?
Hint: To calculate the wheel's circumference, use the formula 2πr, where r is the radius and π=3.14 , to first determine the distance covered in one revolution. To determine the distance traveled, multiply the distance covered in one revolution by 200. In the end, multiply it by 100 to get the distance in meters.
In mathematics, what is the circumference?
The distance between the center of the sphere and any plane passing through it is known as the circumference. Any large circle that passes through a point known as a pole is called a meridian.
The circle's circumference must be known in order to compute the distance covered during one rotation. C=2πr is the formula for the circumference.
The radius, designated as r, is 36 inches. As a result, C=2π36 = 72π. The distance covered in one rotation is 226.08 inches because (pi) =3.14159, C=226.08 inches. So when we rotate this 4 times the it travels 226.08 * 4 = 904.32 inch

The monthly payment (R) needed to have a sinking fund accumulate the future value (A) is equal to $325.08
What is Future Value?
Future value (FV) is the value of an asset now based on an anticipated rate of increase in the future. Investors and financial planners use the future value to project how much an investment made now will be worth in the future.The formula for future value (A) is given as, [tex]A=\frac{R[(1+\frac{r}{n})^{nt}-1] }{\frac{r}{n}}[/tex], where R is the monthly payment, r is the yearly interest rate, t is the time (in years) and n is the number of compounding (monthly).Here, the given values are:
A=$4,000;
r=5.5%=0.055
t=1 year
And it is given that the interest is compounded monthly.
So, n=12
Using the formula for Future Value, [tex]A=\frac{R[(1+\frac{r}{n})^{nt}-1] }{\frac{r}{n}}[/tex]
Substituting the given values in the above equation, we get
[tex]4000=\frac{R[(1+\frac{0.055}{12})^{12 \times 1}-1] }{\frac{0.055}{12}}\\\implies 4000=\frac{R[(1+0.0046)^{12}-1] }{0.0046}\\\implies 4000=\frac{R \times 0.0566 }{0.0046}\\[/tex]
Rearranging the above expression in terms of the monthly payment, we get
[tex]R=\frac{4000 \times 0.0046}{0.0566} \\\implies R=325.08[/tex]
Therefore, the monthly payment (R) needed to have a sinking fund accumulate the future value (A) is $325.08

Consider a student loan of $25,000 at a fixed APR of 9% for 20 years.
a. Calculate the monthly payment.
b. Determine the total amount paid over the term of the loan.
c. Of the total amount paid, what percentage is paid toward the principal and what percentage is paid for interest.
The monthly payment will be $161.20.The total amount paid over the term of the loan is $38,688 and 58.2% is paid toward the principal while 41.8% is paid toward interest.
What is compound interest?Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.
As per the given,
Principle amount P = $25,000
APR = 9% = 0.09
Time period T = 20 years
a) Monthly payment will be given as,
⇒ P(r/12)/(1 -(1 +r/12)^(-12t))
⇒ 22500·(0.06/12)/(1 -(1 +0.06/12)^(-12·20))
⇒ $161.20
b) After 20 years the amount as,
$161.20 x 240 = $38,688
c) (22500/38688)·100% = 58.2% is paid toward principal
The remaining amount, 41.8% is paid toward interest.
Hence "The monthly payment will be $161.20.The total amount paid over the term of the loan is $38,688 and 58.2% is paid toward the principal while 41.8% is paid toward interest".
