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

Answer:

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.

What is the difference of your two numbers?

32.46 and 32.56

The numbers greater than 32.46 and less than 32.56 are:

32.47, 32.48, 32.49, 32.50, 32.51, 32.52, 32.53, 32.54, 32.55

We can choose any two numbers from the listed

32.48 and 32.54

Hence,

The difference between the two numbers is

= 32.54 - 32.48

= 0.06

the answer is 300 because 55+45=100   and 100*3 is 300

What is triple the sum of 45 and 55

First, add 45 and 55

45 + 55 = 100

Next, triple the sum. Multiply 3 with the number gotten

3(100) = 300

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!

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.

y is the total number of votes, which is given as 125,000

Add 62500 to both sides:

X = 31250 + 62500

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

Answer:

Step-by-step explanation:

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:

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

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.

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.

The largest alligator ever recorded and taken in the state of Mississippi weighed 727 pounds. This is an exceptional case, as alligators usually weigh less.

Yes, the largest alligator ever recorded and caught in the state of Mississippi weighed 727 pounds. This monumental creature stands as a testament to the potential size that members of the alligator species can achieve under optimal conditions. It's always imperative to understand that different species have varied weight standards, and this is no exception when it comes to alligators.

Without more information or a diagram showing the arrangement of the angles, we can't accurately determine if angles 2 and 5 are vertical angles, linear pairs, or neither. Vertical angles are those opposite each other when lines intersect and are always equals, while a linear pair of angles add up to 180 degrees and share a vertex and a side.

To determine if angles 2 and 5 are vertical angles, linear pairs, or neither, we need to know the positional arrangement of these angles.

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in degree.

A linear pair of angles is formed when two angles add up to 180 degrees and they share a vertex and a side.

Without a diagram or more context, it's impossible to determine the relationship between angles 2 and 5. Please provide more information or a diagram to help identify the relationship between these angles.
