At a sports camp, there is one counselor for every 12 campers. If there are 156 campers attending the camp, which equivalent ratios could be used to find the number of counselors?

Answer:

They sold 513 turkey sandwiches.

Step-by-step explanation:

Let t be the number of turkey sandwiches and s be the number of steak sandwiches.

With these variables, we can create equations for the totals they've given us:

Total sandwiches = [tex]t+s=925[/tex]

Total income = [tex]4t+6s=4524[/tex]

Now we can solve the system for the number of turkey sandwiches and steak sandwiches

[tex]4\left(925-s\right)+6s=4524[/tex]

[tex]3700-4s+6s=4524\\3700+2s=4524\\3700+2s-3700=4524-3700\\2s=824\\\frac{2s}{2}=\frac{824}{2}\\s=412[/tex]

[tex]t=925-412\\t=513[/tex]

They sold 513 turkey sandwiches and 412 steak sandwiches.

You are required to sell a minimum of 180,001 of jewelry each year.

Given that,

Based on the above information, the following expression should be made:

16,000 + 0.07x > 25,000 + 0.02x

0.07x - 0.02x > 25,000 - 16,000

0.05x > 9000

x > 9000 ÷ 0.05

x > 180,000

Therefore we can conclude that you are required to sell a minimum of 180,001 of jewelry each year.

Final answer:

Mr. Smith should deposit $119,631.97 now to have $500,000 in his bank account after 16 years, assuming a 10% annual compound interest rate.

Explanation:

To calculate how much Mr. Smith should deposit now to attain his retirement goal of $500,000 in 16 years with an annual compound interest rate of 10%, we use the formula for the present value of a future sum, which is:

PV = FV / (1 + r)^n

Where:

PV is the present value (the amount to deposit now)

FV is the future value (the desired amount in the account)

r is the annual interest rate (as a decimal)

n is the number of years

Plugging in Mr. Smith's values, we have:

PV = $500,000 / (1 + 0.10)^16

Calculating the denominator first:

(1 + 0.10)^16 = 1.10^16 = 4.1772

Now, divide the future value by this amount:

PV = $500,000 / 4.1772
= $119,631.97

Therefore, Mr. Smith should deposit $119,631.97 now to reach his goal of $500,000 in 16 years with a 10% annual compound interest rate.

Answer:

The interest paid will be $9.946 ≈ $9.95.

Step-by-step explanation:

p = 1256.34

r = [tex]9.5/12/100=0.007917[/tex] (monthly)

Now, given is :

A late payment fee of $29.00 is added to the principal if you pay after 5/28. You make a payment for $200.00 on 5/28.

As the payment is made on the last date, so no extra charge will be paid. So, it is simple interest of [tex]1256.34\times0.007917=9.946[/tex]

Hence, the interest paid will be $9.946 ≈ $9.95.

Statements I and III are true as per the defined function y=x^2+2. The graph of this function would have all points above the origin and all points would have positive y-values. Statement II is incorrect as x can take both negative and positive values.

Considering the three statements given, only the statements I and III are true. This is because for the function y = x^2 + 2, all points on the graph are above the origin and all points on the graph have positive y-values.

Statement I is true because the function x^2 is non-negative for all values of x, which means that the minimum value of x^2 is 0. As a result, the minimum y−value for the function is 2 when x=0 and the lowest point on the graph is (0, 2), which is indeed above the origin.

Statement III is true because the lowest point on the graph is (0, 2) and since 2 is positive all other points have a y−value that is greater than 2 and therefore must be positive. Statement II is not true as x can take both negative and positive values in the function y=x^2+2.

To solve this problem, we have to make use of the z statistic. The formula for z score is:

z = (x – u) / s

where x is the sample value = 18,000 to 30,000, u is the sample mean = 30,000, and s is the standard deviation = 10,000

at x = 18,000

z = (18,000 – 30,000) / 10,000 = - 1.2

at x = 30,000

z = (30,000 – 30,000) / 10,000 = 0

So find for the P at values of z = -1,2 and z = 0.

P (z = - 1.2) = 0.1151

P (z = 0) = 0.5000

The proportion in between is the difference:

P (18,000 < x < 30,000) = 0.5000 – 0.1151 = 0.3849

So about 38.49% can be expected to travel 18,000 to 30,000 miles in a year

Using z-scores and the normal distribution, we can calculate that approximately 38.49% of trucks can be expected to travel between 18 and 30 thousand miles in a year.

This problem involves the normal distribution in mathematics, particularly statistics. Given that the distance travelled per truck per year is normally distributed, we can calculate the proportion of trucks that may be expected to travel between 18 and 30 thousand miles in a year using z-scores.

The first step is to calculate the z-scores for the two distances we are concerned with. The z-score is a measure of how many standard deviations an element is from the mean. Given a mean of 30 thousand miles and a standard deviation of 10 thousand miles, the z-score for 18 thousand miles is (18 - 30) / 10 = -1.2, and the z-score for 30 thousand miles is (30 - 30) / 10 = 0.

You then need to find the area between these two scores on a standard normal distribution table, which gives you the proportion of trucks likely to travel this distance. Looking up -1.2 and 0 in a standard normal table gives us values of 0.1151 and 0.5000 respectively. The difference between these two areas (0.5000 - 0.1151) is 0.3849, or 38.49% when expressed as a percentage. Thus, we can expect approximately 38.49% of trucks to travel between 18 and 30 thousand miles in a year.

Answer:

11.33%

Step-by-step explanation:

Amount of salt which Larry has to mix= 15 grams

In 210 gm of salt solution, content of salt= 5%

Amount of salt in salt solution= 5 % of 210 grams

Amount of salt in salt solution= [tex]\frac{5}{100}[/tex] of 210 grams

Amount of salt in salt solution= [tex]\frac{21}{2}[/tex]

Amount of salt in salt solution= 10.5 grams

Now the 15 grams of salt have to mix with 5% of salt solution

Total amount of salt= 15+ 10.5

Total amount of salt = 25.5 gram

Total amount of salt solution=15+ 210= 225 grams

Percentage of salt in new solution=[tex]\frac{amount of new salt}{ amount of new solution}[/tex] ×100

Percentage of salt in new solution=[tex]\frac{25.5}{ 225}[/tex] ×100

Percentage of salt in new solution= 0.13333×100

Percentage of salt in new solution= 11.33%  (approx)

Hence, the correct answer is 11.33%

Answer:

The next town is 62.5 miles away.

Step-by-step explanation:

Scale problems can be solved by a simple rule of three.

The scale on a map is 2 cm=25 miles

This means that for each 2cm we measure on the map, the real distance is 25 miles.

Dave measured the distance to the next town at 5cm. Hoiw many miles away is the next town?

How many miles are 5 cm. So

2cm - 25 miles

5cm - x miles

[tex]2x = 25*5[/tex]

[tex]x = 62.5[/tex]

The next town is 62.5 miles away.

The equation of the parabola with vertex (5, -3) and passing through (6, 1) in vertex form is y = [tex]4(x - 5)^2 - 3.[/tex]

To write the equation of a parabola in vertex form, we use the formula:

y = [tex]a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola. Given the vertex (5, -3) and a point (6, 1) the parabola passes through, we can plug these values into the equation to find a.

For the point (6, 1):

[tex]1 = a(6 - 5)^2 - 3[/tex]

[tex]1 = a(1)^2 - 3[/tex]

4 = a

So, the equation of the parabola in vertex form is:

y = [tex]4(x - 5)^2 - 3[/tex]

A logarithmic equation involving natural logarithms can be solve by taking the exponent of both sides

How to solve a natural logarithmic equation for x

To solve an equation involving the natural logarithm of x, you generally follow these steps:

Take for instance, the equation is of the form

2 + ln(x) = 7

Isolate the natural logarithm

ln(x) = 5

Take the exponent of both sides

So, we have

[tex]x = e^5[/tex]

Evaluate the exponent

x = 148.41

Hence, the logarithmic equation solved for x is x = 148.41
