Without a specific question or context, it is difficult to provide a meaningful response or analysis. Please provide more information or clarify the question.

To find the measurement of an angle whose tangent is 2/7, you can use the inverse tangent function (also known as arctan or tan^-1).

The inverse tangent of 2/7 is denoted as arctan(2/7) or tan^-1(2/7). Using a calculator or mathematical software, you can determine the value of this expression.

Approximately, arctan(2/7) is equal to 0.2856 radians or 16.26 degrees.

Therefore, the measurement of the angle whose tangent is 2/7 is approximately 16.26 degrees or 0.2856 radians.

Answer:

The value of the expression is 7.5

Step-by-step explanation:

To calculate the value of the expression -4 + (4.5 + 7), we first need to simplify the inner parentheses:

-4 + (4.5 + 7)

-4 + 11.5

Next, we can perform the addition:

-4 + 11.5 = 7.5

Therefore, the value of the expression -4 + (4.5 + 7) is 7.5.

The percent change is 20%.The correct answer is option C.

To calculate the percent change, we can use the following formula:

Percent Change = (New Value - Old Value) / Old Value * 100

In this case, the old value is $25 (the previous cost to fill the gas tank), and the new value is $30 (the current cost to fill the gas tank).

Percent Change = ($30 - $25) / $25 * 100

Percent Change = $5 / $25 * 100

Percent Change = 0.2 * 100

Percent Change = 20%

Therefore, the percent change is 20%. So the correct answer is C. 20%.

The value of x for the chord is:

x = 12

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc.

Recall that: If two chords intersect inside the circle, then they cut each other in such a way that the product of the lengths of the parts is the same for the two chords.

Using the above principle, we can say:

3 * x = 4 * 9

3x = 36

x = 36/3

x = 12

Thus, the value of x for the chord is 12.

Mr. Burst needs to eat more than 8 minutes to beat Mr. Bean's record.

Let's define the variables:

x - the number of minutes Mr. Burst has been eating spring rolls

y - the total number of spring rolls Mr. Burst has eaten

Based on the given information, we can set up the following inequality:

y = 8 + 4.5x (equation representing the number of spring rolls Mr. Burst has eaten)

We want Mr. Burst to eat more than 44 spring rolls to beat Mr. Bean's record. Therefore, we can set up the inequality:

y > 44

Substituting the equation for y, we have:

8 + 4.5x > 44

To solve for x, we can isolate the variable:

4.5x > 44 - 8

4.5x > 36

x > 36 / 4.5

x > 8

Mr. Burst needs to eat more than 8 minutes to beat Mr. Bean's record.

To graph the solution, we plot the inequality on a number line, shading the region to the right of x = 8. This shows all the possible values of x that satisfy the inequality. The y-axis represents the number of minutes, and the x-axis represents the number of spring rolls.

Answer:

Cost of Washer = $696

Cost of Dryer = $232

Step-by-step explanation:

Start by making and equation, put a variable for the missing prices, let's say the cost of the dryer is 'x' and since the cost of the washer is three times, it will be '3x'.

Put the equation together, so we can add the x variables together.

3x + x = 4x

The total cost will be what the '4x' is equal to.

4x = 928

Going back to algebra, we solve the equation by dividing both sides by 4.

x = 232

Remember x is the variable we gave to the dryer, so now we must find the cost of the washer. In order to do this, we will have to multiply it by 3.

3x

3(232) = 696.

To check the answer, we can add them together to make sure we get the total cost.

696 + 232 = 928

Answer:

a) -4653.
b) -9180.
c) -2700.

Step-by-step explanation:

a) To evaluate using the distributive property, we can break down the multiplication as follows:

-99 x 47 = (-100 + 1) x 47 [Using the fact that -99 can be expressed as -100 + 1]

= (-100 x 47) + (1 x 47) [Distributive property]

= -4700 + 47

= -4653

Therefore, -99 x 47 = -4653.

b) Similarly, we can break down the multiplication using the distributive property:

-85 x 108 = (-100 + 15) x 108 [Using the fact that -85 can be expressed as -100 + 15]

= (-100 x 108) + (15 x 108) [Distributive property]

= -10800 + 1620

= -9180

Therefore, -85 x 108 = -9180.

c) Using the distributive property:

(-54) x 12 + (-38) x 54 = (-54 x 12) + (-38 x 54)

= -648 + (-2052)

= -648 - 2052

= -2700

Therefore, (-54) × 12 + (-38) × 54​ = -2700.

Answer:

Hence, n 3 −n=n(n+1)(n−1) is divisible by 6.

Step-by-step explanation:

The condition for any number to be divisible by 6 is that the number must be individually divisible by 3 and 2.

Check whether n 3−n is divisible by 3.

n3−n=n(n+1)(n−1)

When a number is divided by 3 then by the remainder theorem, the remainder obtained is either 0 or 1 or 2.

n=3p or n=3p+1 or n=3p+2, where p is some integer.

If n=3p, then the number is divisible by 3.

If n=3p+1, then n−1=3p+1−1=3p. The number is divisible by 3.

If n=3p+2, then n+1=3p+2+1=3(p+1). The number is divisible by 3.

So, any number in the form of n

When a number is divided by 2, the remainder obtained is either 0 or 1 by the remainder theorem.

n=2p or n=2p+1, where p  is some integer.

If n=2p, then the number is divisible by 2.

If n=2p+1 then n−1=2p+1−1=2p. The number is divisible by 2.

So, any number in the form of n
