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:

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.

Add the lengths of the three sides.

P = 2x + 1 + x + 2 + 3x

P = 2x + x + 3x + 1 + 2

P = 6x + 3

The quantity which is unknown can be represented as a variable such as x or any other letter. The plus 6 can be represented by +6. So the final answer is x+6. Hope this helps!

Remember this: 4 or below let it go (round down) 5 or above give it a shove (round up)

remember your only rounding 100,000 place so leave the digit behind that

answer: 8,000,000 since it is 4 or below.

8,500,00 is the answer to the nearest 100,000 because 473 is the hundreds place and since 7 is above 5 you round up

The function is y=450-50x.

Answer: 126

Step-by-step explanation: You would just find the LCM (2, 3, 7) and get 42. But since you need a 3-digit number, list the multiples of 42, like so: 42, 84, 126, 168, 210...

As you can see, 126 is the smallest 3-digit number that has 2, 3, and 7 among its prime factors.

The smallest 3-digit number that has 2, 3, and 7 among its prime factors is 126.

The smallest 3-digit number that has 2, 3, and 7 as its prime factors can be calculated by multiplying the prime factors together. In this case, it's 2 x 3 x 7, which equals 42. This is a 2-digit number, but we're looking for

3-digit

number. The next multiple of 42 (42 x 3) gives us 126, which is a 3-digit number. So, the

smallest 3-digit

number that has 2, 3, and 7 as its prime factors is

126

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

Step-by-step explanation:

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.

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.

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.

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.

5b+4+10=-2

5b+14=-2

5b+14-14=-2-14          1)  subtract 14 from both sides

5b=-16

5b/5=-16/5                 2) divide by 5 on both sides

b=3 & 1/5

The answer is b = -3.2.

First, you have to add 4 and 10 together to get 14. Then, you subtract 14 from 14 and negative 2. You will get negative 16 because since the 2 is already a negative, you would just be adding two negatives. Next, the equation should look like this: 5b = -16. Now, you would divide by 5 on each side and your answer should be b = -3.2. Hope this helps!

32.48 and 32.50 is the numbers which are more than 32.46 and less than 32.56 and there difference is 0.02

Step-by-step explanation:

We have given two numbers 32.46 and 32.56

We have to find two numbers which are greater than 32.46 but less than 32.56

The number 32.48 is greater than 32.46 and less than 32.56

And other number 32.50 is greater than 32.46 and less than 32.56

Now we have to find the difference of these two numbers

So difference = 32.50 - 32.48 = 0.02

The two numbers that are greater than 32.46 and less than 32.56 are 32.48 and 32.54.

a flat figure with 4 equal straight sides and four right angles

Answer: Hello there!

We want to find a counterexample to: "a square has four right angles" then we need to find a figure that has four right angles and is not a square.

A first example can be a cross (two segments that cut each other and are perpendicular), but let's think in a geometric shape.

Think on a square that in the middle of each side has a small semicircle; this shape still has four right angles but is not more a square.

There you have two counterexamples of the definition given.

Formula d = vt

1 3/4= 1.75

1/4=0.25

So now plug into equation

To find v first to find per hr.

v = (1.75 miles) / (0.25 hrs) =

7 miles per hr

Distance per hr

d = (7 miles/hr)(1 hr) = 7 miles

In 3 hrs ?

d = (7 miles/hr)(3hr) = 21 miles

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
