10ⁿ = 1
a) n=1
b) n=0
c) n=2

Answers

Step-by-step explanation:

n = 0

because,

p^0 = 1

10000000^0 = 1

B) n = 0

Anything to the power of 0 not matter the number is always equal to 1.

For ex:

1^0 = 1
100^0 = 1
10000000000^0 = 1

Even 0^0 = 1

Evaluate the expression below
if a = -8, b = 17, and c = 21
a2 –(b+c)

Answers

Answer:

-54

Step-by-step explanation:

first fill in the numbers

next do the parentheses 17 + 21=38

then find -8×2 which equals -16

then subtract -16 from 38 and get -54

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

⇒ a² - (b + c)

The value of the expression at a = -8, b = 17, and c = 21 will be

⇒ a² - (b + c)

⇒ (-8)² - (17 + 21)

⇒ 64 - 38

⇒ 26

The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

question:: 81% of 49 is what?

Answers

Answer:

39.69

Step-by-step explanation:

Make the following equation: 81/100 = x/49. Then, multiple 81 and x by 49. Divide the answer, 3969, by 100, which gives you the answer.

39.69. because percentages are parts of 100, you can change the form of 81% to .81. the ‘of’ in ‘81% of 49 indicates multiplication, so to solve this you do .81 x 49, which equals to 39.69

Don has two jobs. For Job 1, he earns $7.55 an hour. For Job 2, he earns $8.45 an hour. Last week he worked at the first job for 10 hours and at the second job for 15 hours. What were his average earnings per hour? a $8.15 b $8.13 c $8.00 d $8.09

Answers

Answer:

D. $8.09

Step-by-step explanation:

Get the total amount for Job 1 & Job 2 he worked for x amount of hours. The x amount of hours and the amount of earnings he get per hour is given to us:

Job 1: $7.55 x 10 = $75.50

Job 2: $8.45 x 15 = $126.75

Add two total costs from work:

$75.50 + $126.75 = $202.25

You add 10 + 15 to get 25 and we need this number for the average as he worked 25 hours in total:

$202.25 / 25 = $8.09 per hour

Don's average earnings per hour is $8.09 per hour.

solve for x

Answers

Answer:

The length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]

Option A is correct.

Step-by-step explanation:

We are given: [tex]Area\:of\:rectangle=Length\times Width[/tex]

if [tex]Area = 24x^6y^{15}[/tex]we need to find the length and width of rectangle from options given.

Looking at the options, Option B,C and D are incorrect because multiplying the given lengths and widths, the area is not equal to [tex]24x^6y^{15}[/tex]

Only Option A gives us the result i,e

[tex]Area=2x^5y^8\times 12xy^7\\Area=24x^6y^{15}[/tex]

So, the length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]

Option A is correct.
