VAn item costs $310 before tax, and the sales tax is $6.20.Find the sales tax rate. Write your answer as a percentage.0%X5?

we have the following:

Therefore, the answer is 121.7 yards

Answer: 8 inches

Step-by-step explanation:

1) Set up the equation

If you know both sides of the triangle are 6 inches you can set a Pythagorean equation. C is the hypotenuse

[tex]6^2+6^2=c^2\\36+36=c^2\\72=c^2\\\sqrt{72} = \sqrt{c^2} \\8.485 = c[/tex]

2) Rounding

After you found 8.485, the tenth place is less the 5, so it will round down to 8 inches.

The answer is 8 inches

4.6

1) Since 3/4x = 3.45, then we can solve it for x

3/4x = 3.45 Multiply both sides by 4 to eliminate the fraction

3x =13.80 Divide both sides by 3

x= 4.6

2) So x is equal to 4.6, and that is the answer

Answer:

Explanation: We have to find the mean of the total scores shown, the formula for the mean is as follows:

Using the formula (1) the mean of the score is calculated as follows:

Therefore the answer is Option(D).

Notice that for every 6 units increment in the x-values in the table, there is a 2 units increment in the y-values.

Therefore, the constant of proportions is:

To find the equation, we'll use this constant as the slope. Using this, point

This way the equation is:

There are 7 % of Americans over age 100 who were there in 2000 and the number of Americans growing by 54% over age 100 changed in 2000.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

The number of Americans over age 100 can be approximated by

[tex]P(t) = 0.07e^{0.54t}[/tex]

where is P(t) measured in millions and t is measured in decades.

Also, t = 0 corresponds to 2000.

⇒ [tex]P(t) = 0.07e^{0.54t}[/tex]

Substitute the t = 0 in the above function, and we get

⇒ [tex]P(t) = 0.07e^{0.54\times0}[/tex]

⇒ P(t) = 0.07 e°

⇒ P(t) = 0.07

Convert decimals into fractions, and we get

⇒ P(t) = 7 / 100

This represents 7 out of 100 which is 7 % of Americans over age 100 who were there in 2000.

Thus, the number of Americans growing by 54% over age 100 changed in 2000.

The time it would take Mowgli from the home to the beach and from the beach to the home on foot is 48 minutes.

Based on the assumption that the average speed that Mowgli travels from the home to the beach and from the beach to the home is constant, the time it takes from the home to the beach and from the beach to the home should be equal.

Time from the home to the beach = 32 /2 = 16 minutes

The time it took Mowgli to walk from the home to the beach = 40 - 16 = 24 minutes

The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;

⇒ P (C ∪ S) = 0.76

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

48% of people in a certain country like to cook.

And, 54% of people in the country like to shop, while 26% enjoy both activities.

Now,

Probability to like the cook P (C) = 48%

Probability to like the shop P (S) = 54%

Probability to like the both activity P (C∩S) = 26%

So, Probability to like the both activity P (C ∪ S) is calculated as;

P (C ∪ S) = P (C) + P (S) - P (C ∩ S)

P (C ∪ S) = 48% + 54% - 26%

P (C ∪ S) = 102% - 26%

P (C ∪ S) = 76%

P (C ∪ S) = 0.76

Thus, The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;

⇒ P (C ∪ S) = 0.76

If  the weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. The gaskets  that should be thrown out is 0.53  and the inequality is: 0.54 ≤ w ≤ 0.66.

Using this formula to determine the mean

Mean = ∑x/n

Mean = 0.58 + 0.63 + 0.65 + 0.53 + 0.61 /5

Mean = 3/6

Mean = 0.6

Answer

The temperature at an altitude of 8,000 feet is 44° F

SOLUTION

Problem Statement

The question tells us that air temperature drops by 4 degrees Fahrenheit for every 1,000 feet above sea level. We are asked to calculate the temperature at 8,000 feet, close to the summit of Guadalupe Peak.

Solution

To solve this question, we simply compute the temperature changes for each 1,000 increase in height and then generalize. With the generalization, we can find the temperature at any height.

The temperature at 0 feet is 76°F (At sea level)

The temperature at 1,000 feet is 76°F - 4°F = 72° F

The temperature at 2,000 feet (2 x 1,000 feet) is 76°F - 4°F - 4°F (76°F - 2 x 4°F)

The temperature at 3,000 feet (3 x 1,000 feet) is 76°F - 4° F - 4° F - 4° F (76° F - 3 x 4° F)

And so on.

We can see a pattern developing and with this pattern, we can make a generalization about the temperature decrease for every increase in altitude.

Thus, we can solve the question by substituting n = 8 for an altitude of 8,000 feet. This is done below:

8 x 1000 feet = 8,000 feet is:

Final Answer

The temperature at an altitude of 8,000 feet is 44° F

To complete the missing values, we have to evaluate the function at the x-values given.

For example, to find the number below x = -1, we will put in x = -1 into y = (1/6)^x.

Putting in x = - 1 in y = (1/6)^x gives

which simplifies to give

Similarly, for the missing value below x = -2, we put in x = - 2 into y = (1/6)^x to get

which simplifies to give

Similarly, for the missing value below x = 2, we put in x = 2 in y = (1/6)^x to get

which simplifies to give

Hence, the missing value to be put in is 36.

Given the sequence:

C. 3, 12, 27, 48, 75

First, we need to calculate the difference between terms:

12-3 = 9 27-12 = 15 48-27 = 21 75 - 28 = 27

Arithmetic relationship: 9, 15 , 21, 27

To obtain the sequence we use the following formula:

Now, we need to calculate the appropriate difference between terms:

15-9 = 6 21-25 = 6 27 - 21 = 6

So the constant difference is 6 and the nth term will be:

nth = 6n + 3
