Answers

Answer:

62.000124 in. cubed

Step-by-step explanation:

cm to inches: 0.3937007874 to 1

the side edges are 3.937007874

Since it's a square pryramid, all of the side lengths are equal. 3.937007874^2 is 15.500031.

The formula for a pyramid: base*height/3

15.500031*12/3 = 62.000124 in. cubed

Un metro cúbico equivale a 1000 litros de capacidad y un decímetro cúbico a un litro ¿Cuántos litros cabrán en una piscina de 12,5 metros cúbicos?

Answers

Answer:

12,500 liters

Step-by-step explanation:

Given that

One cubic meter = 1000 liters

One cubic decimeter = 1 liter

We need to find out the number of liters fit in a 12.5 cubic meter

So

As it is mentioned that

One cubic meter = 1000 liters

So for 12.5 cubic meter

The number of liters would be

= 1000 × 12.5

= 12,500 liters

What are the opposites of 5, −3.4, 3.35, and 9 1 3 ? Enter the answers in respective order, each separated by comma.

Answers

Answer:

-5, +3.4, -3.35, and- 9 1 3

Step-by-step explanation:

To find the opposite of any number we multiply it with -1 or divide it with -1

The opposite of 5 is given by  5 (-1)= -5

The opposite of -3.4 is given by  -3.4 (-1)= 3.4

The opposite of 3.35 is given by  3.35 (-1)= -3.35

The opposite of 913 is given by  913 (-1)= -913

This property is called the additive inverse. The additive inverse is that property which on addition of the numbers gives the answer = zero.

5-5= 0

-3.4+3.4= 0

3.35-3.35=0

913-913=0

Answers

Answer: The answer is -22.

Answer:

-22

Step-by-step explanation:

PEMDAS

P - Parentheses/Brackets -> -6+[-2(6+2)] = -6+[-2(8)]

E - Exponents -> None

M - Multiplication left to right -> -6+[-2(8)] = -6+[-16]

D - Division left to right -> None

A - Addition left to right -> -6+[-16] = -6-16 = -22

S - Subtraction left to right -> See addition

Therefore, your answer is -22.

What is the probability of flipping a coin 7 times and getting heads 5 times? Round your answer to the nearest tenth of a percent.

Answers

For a fair coin,
Probability of a head, P(H) = 1/2 = 0.5
Probability of a tail , P(T) = 1/2 = 0.5
The number of possible outcomes is small enough to simply list the outcome:
The possible outcomes of flipping a coin 7 times and getting heads 6 times are these 7 possibilities:
THHHHHH
HTHHHHH
HHTHHHH
HHHTHHH
HHHHTHH
HHHHHTH
HHHHHHT
The probability of EACH of the above outcomes is
= (0.5)(0.5)(0.5)(0.5)(0.5)(0.5)(0.5)
= (0.5)⁷
Since there are 7 possibilities and since the probabilities of every outcome is identical, the probability of rolling the 7 outcomes is,
= 7 x probability of each outcome
= 7 x (0.5)⁷
= 0.5468
= 5.468%
= 5.5% (nearest tenth)

How many four-letter codes can be made if no letter can be used twice?

Answers

There are 26 letters in the alphabet.

1st letter can be 1 of 26

2nd letter can be 1 of 25

3rd letter can be 1 of 24

4th letter can be 1 of 23

Total combinations = 26 x 25 x 24 x 23 = 358,800

Answer:

solution given:

total alphabet =26

The first letter can be any one of the 26 letters in the alphabet.

so

1st word =26letter

since no word is repeated

2nd word =25letter

3rd word=24letter

4th word=23letter

so

four-letter code =26×25×25×23=358800codes

so

358800codes of four-letter codes can be made if no letter can be used twice.

Question 5: The missing term her is r²

Question 6: The missing term here is 3.

Step-by-step explanation:

Question 5:

Let's write the equation and then solve it for the missing term. We will call this term x.

[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]

First, we simplify the letf term adding the similar terms.

[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]

Now, we substract 4r⁴ and 7r in both sides.

[tex]x=r^{2}[/tex]

Therefore, the missing term her is r²

Question 6:

Here, we will call the missing term y. Now, let's solve it for y.

[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]

Let's first distribute the minus sign into the parentehsis.

[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]

Now simplify the left side by adding similar terms.

[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]

Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.

[tex]y=10-7[/tex]

[tex]y=3[/tex]

Therefore, the missing term here is 3.

the radius is 2.5 all you had to do was divide 5 by 2 lol

Answer:

2.5

Step-by-step explanation:

The radius is any line from the middle of the circle to the end of the circle. The diameter is a chord which is a line going from any end of the circle to the other end but the diameter crosses though the point which is in the middle.

So, you split the diameter in half. 5/2 = 2.5

Is water wet?? Explain

Answers

Answer:

WATER IS not wet

Step-by-step explanation:

Water is NOT wet by itself, however it makes other materials wet when it sticks to the surface of them.

Answer:

Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

Evaluate the expression for a = 3, b = 4, and c = 6
a^3 - b + c

Answers

Answer:

3^3 - 4+6 = 17

Step-by-step explanation:

First you would do the exponents. 3 to the power of 3 (3^3) is 27.

Then you would add 4 and 6 (4+6) which will give you 10.

Finally, you would need to subract 10 from 27 (27-10) and you would get 17.

Hope this helps! :)

Answer:

29

Step-by-step explanation:

The expression is

a^3 - b + c

You just have to plug in the numbers, then evaluate,,

(3)³ - (4) + (6)

Let's start off with the exponent, so (3)³ = 3×3×3

3×3=9

9×3=27

Now, we have 27 - (4) + (6)

We have to get rid of the parenthesis so multiply the symbol next to it, - × 4 = -4, and + × 6 = +6. Now rewrite the equation.

27 - 4 + 6

27 - 4 = 23

23 + 6 = 29

Therefore, the answer its 29.

Hope this helps,

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5

Answers

Answer:

1/18

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Multiples of 3 between 1 - 9 = 3,6,9

Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag

3/9

To transform to the simplest form. divide both the numerator and the denominator by 3

1/3

After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6

Probability of picking 5 = 1/6

1/6 x 1/3 = 1/18
