Answer:

24.5

Step-by-step explanation:

If you multiply 2 and 24.5 together you would get 49

The value of the solution to the given equation is 7, which is the correct answer that would be option (D).

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

The equation is given in the question following as:

x² = 49

We have to determine the value of the solution to the given equation

As per the given question, we have

⇒ x² = 49

⇒ x² - 49 = 0

⇒ x² - 7² = 0

We know that the formula as, a² - b² = (a + b)(a - b)

Here a = x and b = 7, and we get

⇒ (x + 7)(x - 7) = 0

⇒ x + 7 = 0 and x - 7 = 0

⇒ x = - 7 = 0 and x = 7

Thus, the value of the solution to the given equation is 7,

Hence, the correct answer would be an option (D).

Answer:

Option C.

The two sums are equal.

Step-by-step explanation:

In geometry, the sum of the exterior angles of any polygon will always give 360 degrees. This is regardless of the type of polygon, whether it is a triangle, quadrilateral, pentagon, or a decagon.

This means that the sum of the exterior angles of a square is equal to that of the pentagon.

As the number of sides that they have increases, the sizes of their internal angles get smaller, making the sum of their external angles remain at 360 degrees

Answer:

n = 0 or n = -9/16

Step-by-step explanation:

Solve for n:

2 (8 n^2 + 9 n) - 9 n = 0

Hint: | Write the quadratic polynomial on the left hand side in standard form.

Expand out terms of the left hand side:

16 n^2 + 9 n = 0

Hint: | Factor the left hand side.

Factor n from the left hand side:

n (16 n + 9) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

n = 0 or 16 n + 9 = 0

Hint: | Look at the second equation: Isolate terms with n to the left hand side.

Subtract 9 from both sides:

n = 0 or 16 n = -9

Hint: | Solve for n.

Divide both sides by 16:

Answer: n = 0 or n = -9/16

Answer:

1363.6

Step-by-step explanation:

let the basic salary be = x

10% of x = 10/100x

So the equation = x + 10/100x = 1500

                           = x + 0.1x = 1500

                           = 1.1x = 1500

                           =  x = 1500/1.1

                           =  x = 1363.6

Step-by-step explanation:

2 x (16 + (10 + 3) - 3) - 22

2 x (16 + 13 - 3) - 22

Answer:

DOMAIN: [tex](-\infty,1]\cup(2,\infty)[/tex]

RANGE: [tex](-\infty,\infty)[/tex]

Step-by-step explanation:

The domain of a graph is the span of x-values covered by the graph, while the range of a graph is the span of y-values covered by the graph.

DOMAIN:

From the graph, we can see that the x-values covers everything to the left of x=1. Then we stop and then continue beginning at x=2 all the way until positive infinity.

However, note that at x=1, the dot is a closed circle while at x=2, the dot is an open circle. Thus, we will include x=1 into our domain but not include x=2 into our domain.

So, our domain is all values greater than or less than 1, and all values greater than 2.

In interval notation, this is:

[tex](-\infty,1]\cup(2,\infty)[/tex]

We use brackets with the 1 because we include it in our domain and we use parentheses with the 2 since we do not.

RANGE:

Looking at the graph, it seems that all y-values are covered. The part of the graph on the left covers all y-values less than or equal to 3, while the part of the graph on the right covers all y-values greater than -1. Thus, all y-values are covered.

Our range is all real numbers.

In interval notation, this is:

[tex](-\infty,\infty)[/tex]

The resulting number is 72895.5.

To round the number given on statement we must truncate all digits that are less than a tenth and ascend the tenth digit to its next one. Please notice than tenth digits is the digit right after the separator.

Step 1 - Truncate digits less that a tenth:

[tex]x = 72895.4[/tex]

Step 2 - Ascend the tenth digit to its next one:

[tex]x = 72895.5[/tex]

Explanation:

Assume the gumball machine only has 5 gumballs, one of each color. The probability of getting yellow is 1/5 since there is one that is yellow out of 5 total.

The probability of getting a lion rubber band is 1/4 for similar reasoning as above.

Because the two events (getting yellow, getting a lion) are independent, this means we can multiply the two probabilities to get (1/5)*(1/4) = 1/20

Use your calculator to see that 1/20 = 0.05 which converts to 5% when you move the decimal point over 2 spots to the right.

Answer:

2167.2

Step-by-step explanation:

Answer:

2167.2

Step-by-step explanation:

For this problem, let's use the distributive property to make this multiplication easier.

4.2 can be redistributed into 4 & 1/5, as 0.2 == 1/5.

Now let's multiply these numbers with 516.

(516 * 4) + (516 * 1/5) == ?

(2064) + (103.2) == ?

2167.2 == ?

So the product of 516 and 4.2 is equal to 2167.2.

Answer:

x=2 is the answer.

Step-by-step explanation:

10+2x+6x=26

10+8x=26

Subtracting 10 on both sides to find out the value of x

8x=16

Dividing 8 on both sides

8x/8=16/8

x=2

===================================================

Explanation:

First focus on the fact that "the average of x and t is y". This means

(x+t)/2 = y

We basically add x and t, then divide by 2 to get the average y

--------

We are then told that s = 2y, so we double the average

s = 2y

s = 2(x+t)/2

s = x+t .... notice the 2's cancel each other out when dividing

s turns out to be the sum of x and t, which is fitting I think

---------

Now find the average of s, x, and t. You'll add the three values and divide by 3

(s+x+t)/3

(s + (x+t))/3

(s + s)/3 .... replace x+t with s

2s/3

2(2y)/3 ... plug in s = 2y

4y/3

The average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3

From the question, we are to determine the average of s, x, and t in terms of y

From the given information

The average of x and t is y

That is,

(x+t)/2 = y

∴ x + t = 2y

Also,

s = 2y

The average of s, x, and t is

(s + x + t) / 3

Putting the values of x + t and s into the above expression, we get

(2y + 2y)/3

This becomes

4y/3

Hence, the average of s, x, and t in terms of y is 4y/3. The correct option is D. 4y/3

==================================================

Explanation:

The coefficients of each term, from left to right are 1, 3, 3, 1

These coefficient values are found in Pascal's triangle in the third row.

The variable terms will have variable terms in the form a^m*b^n. To start off, m = 3 and n = 0 to get a^3*b^0 = a^3*1 = a^3. From there you will have m count down (3,2,1,0) and n will count up (0,1,2,3)

So for the second term we have m = 2 and n = 1 to get the variable term a^2*b^1 = a^2b

The third term has m = 1 and n = 2 to get the variable term a^1*b^2 = ab^2

Finally the last term has m = 0 and n = 3 to get a^0*b^3 = 1*b^3 = b^3

Those variable terms are them multiplied with the coefficients mentioned previously to get the final answer.

--------------------------

Another way you can do this problem is to use the distributive property and FOIL rule

(a+b)^3 = (a+b)(a+b)^2

(a+b)^3 = (a+b)(a^2+2ab+b^2) .... FOIL rule

(a+b)^3 = a(a^2+2ab+b^2) + b(a^2+2ab+b^2) ... distribute

(a+b)^3 = a*a^2+a*2ab+a*b^2 + b*a^2+b*2ab+b*b^2 ... distribute again

(a+b)^3 = a^3 + 2a^2b + ab^2 + a^2b + 2ab^2 + b^3

(a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3
