Solve for N.

-7 + N = 20

N = 13
N = -13
N = 27
N = -27

Answers

find at least 3 numbers that are palindromes and have square roots that are palindromes

Answers

Hey there!

Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.

Alright, I'll give you four of those:

121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 48410201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 1020112321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321

Hope this helps!

Answer:

1, 4, and 9

Step-by-step explanation:

Since one-digit are palindromes, just take 1, 4, and 9 because they're perfect. In math, you have to be efficient. Don't think too long about higher numbers. Think about the easier cases first.


heba ate 1/12 of a box of cereal now the box is 3/4 full what fraction of a full box was there before heba ate it

Answers

Now box is 3/4 full


3/4 = 3/4*1


3/4 = 3/4 * 3/3 = 9/12


Box is 9/12 full after heba ate 1/12 of a box of cereal


Initial fraction will be 9/12+1/12


=10/12= 5/6

Answer:

5/6.

Step-by-step explanation:

If Heba ate 1/12 of a box of cereal and the box is now 3/4 full, then before she ate the box is 3/4 plus the 1/12 (because, in the "before" situation she hasn't eaten yet). So, we need to add the "now" quantity and the quantity eaten:

[tex]\frac{3}{4}+\frac{1}{12} = \frac{10}{12} = \frac{5}{6}.[/tex]

Then, before she ate the cereal, the box is 5/6 full.

the volume of a cube is 64 cubic inches. what is the length of one side?

Answers

To solve for the volume of the cube, you must use the formula:

Volume = a³

"a" being an edge.

Plug in 64 for Volume

64 = a³

Note the equal sign. What you do to one side, you do to the other. Cube root both sides

∛64 = ∛a³

a = ∛64 = 4

4 inches is your answer

hope this helps

To find the length of one side of a cube with a volume of 64 cubic inches, take the cube root of the volume, which results in a side length of 4 inches.

The volume of a cube is found by cubing the length of one of its sides since a cube's sides are all equal in length. For a cube with a volume of 64 cubic inches, you can find the length of one side by taking the cube root of 64.

Steps to determine the length of one side of the cube:

Understand that the volume of a cube (V) is equal to the side length (s) cubed: V = s³.Since the volume is 64 cubic inches, set up the equation 64 = s³.Take the cube root of both sides of the equation to find s:
s = ³√64 = 4 inches

What is the measure of each exterior angle for a regular nonagon

Answers

The sum of the exterior angles of any polygon is 360 degrees. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees. its my best guess

In a regular nonagon, each exterior angle measures 40 degrees.

A regular nonagon is a polygon that has nine sides of equal length and nine interior angles of equal measure.

To determine the measure of each exterior angle for a regular nonagon, you can follow these steps. Recall that a nonagon is a polygon with nine sides. The sum of the exterior angles of any polygon is always 360 degrees.

Divide the sum of the exterior angles (360 degrees) by the number of sides in the nonagon (9) to find the measure of each exterior angle.

Calculate: 360 degrees ÷ 9 = 40 degrees.

Therefore, each exterior angle in a regular nonagon measures 40 degrees. This means that if you were to extend one side of a regular nonagon outward, the angle formed between that extended side and the adjacent side would measure 40 degrees.

Rafael is taking a test that contains a section of 12 true-false questions. How many of the possible groups of answers to these questions have exactly 8 correct answers of false? a. 425 c. 500 b. 495 d. 515

Answers

Answer: 495

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

We want exactly 8 correct answers of false, so we want exactly 4 correct answers of true.  In short, we want something like FFFF FFFF TTTT. Because the sequence of T values is shorter than the F values, this means it's a lot easier to count out the number of ways to pick the true responses, rather than the false responses.

Consider we have 4 slots: A, B, C, D

In slot A, we can pick the number 1 through 12 to represent getting a T

For slot B, we have 11 choices because we can't reuse whatever we picked for slot A

Then for slot C we have 10 choices

Finally, slot D has 9 choices

Multiply those values out: 12*11*10*9 = 11,880

If order mattered, then we'd be done with the problem. However, order does not matter. This is because a sequence like {1, 2, 3, 4} is the same as {1,2,4,3}. The only thing that matters is that we have the numbers in the same group. We can rearrange any given group however we want.

Note that there are 4! = 4*3*2*1 = 24 ways to arrange any individual group of four items. So we have to divide the previous result 11,880 by 24 and we get: 11880/24 = 495 which is the answer

If you wanted, you can use the nCr combination formula to get this same answer. You would use n = 12 and r = 4

The expression −7x + x³ −6 + x² written in standard form is x³ + x² −7x −6.

Standard form for polynomials is written from the highest degree to the lowest degree of the variables. So, the given expression −7x + x³ −6 + x² should be rearranged as follows:

Identify the term with the highest exponent, which is x³.

Then order the remaining terms by decreasing powers of x: x² comes next, followed by −7x.

Finally, position the constant term at the end, which is −6.

Putting it all together, the polynomial in standard form is x³ + x² −7x −6.

Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.

So instead it should be 0÷(-7)=0

Helen's assertion that division by 0 results in 0 is incorrect. Her error lies in a fundamental mathematical principle: division by zero is undefined in arithmetic.

How to determine Helen error

Dividing any number by 0 is mathematically impossible and not meaningful. It does not yield a value of 0 or any other number because the concept is not valid in standard arithmetic. When you attempt to divide by 0, you encounter mathematical inconsistency and contradiction.

In mathematics, there are well-defined rules and operations for manipulating numbers, and division by zero does not adhere to these rules. It is considered undefined, and no meaningful result can be assigned to it. Therefore, Helen's statement is not accurate, and division by zero is not equivalent to 0 in mathematics.

A trampoline has a rectangular jumping surface that is 10.3 feet long and 9.2 feet wide. What is the area of the jumping surface?

Answers

the area of the trampoline is 94.76 because if you multiply 10.3 and 9.2 you will get the answer

Sure, to find the area of a rectangle, we simply multiply its length by its width. Here, the length of the trampoline's jumping surface is given as 10.3 feet, and the width is given as 9.2 feet.

Step 1: Write down the length and width.
Length = 10.3 feet
Width = 9.2 feet

Step 2: Multiply the length by the width.
Area = Length × Width = 10.3 feet × 9.2 feet

Perform this multiplication to get the area.

Result: The area of the jumping surface of the trampoline is 94.76 square feet.

This means that the total surface area upon which someone can jump on the trampoline is 94.76 square feet.

Adrian earns $3600 per month. he spends 1/4 of his income on rent, 2/5 on food, 1/9 on activities, and he saves the rest. how much does he save each month?

Answers

he saves $860 per month

calculate each of his outgoings

rent = [tex]\frac{1}{4}[/tex] × $3600 = [tex]\frac{3600}{4}[/tex] = $900

food = [tex]\frac{2}{5}[/tex] × $3600 = [tex]\frac{2(3600)}{5}[/tex] = $1440

activities = [tex]\frac{1}{9}[/tex] × $3600 = [tex]\frac{3600}{9}[/tex] = $400

savings = $3600 - ( 900 + 1440 + 400 ) = $860


To add the fractions we must make the denominators = 180.

45/180 + 72/180 + 20/180 = 137/180

Expense Total = (137/180) * 3,600 = $2,740

Savings Total = (180 - 137) / 180

Savings = (43/180) * 3,600

Savings = $860

Your answer is D.


Final answer:

The first step in finding f(x) · g(x) involves multiplying the two functions together, following the distributive property, resulting in terms like 3x³ and 12x².

Explanation:

When finding f(x) · g(x), the first step would involve multiplying the two functions together. This means multiplying each term of f(x) by each term of g(x) using the distributive property.

For f(x) = 3x² - 2x and g(x) = x + 4, the first step would look like:
f(x) · g(x) = (3x² - 2x) · (x + 4) = 3x² · x + 3x² · 4 - 2x · x - 2x · 4 = 3x³ + 12x² - 2x² - 8x

So, the correct option in this case is A) 3x³ + 12x² - 2x² - 8x.
