Step-by-step explanation:
The answer is true
Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

Please help with this! I was having problems with the answer and I just wanted to know if I was right.
Answer:
108 degrees
Step-by-step explanation:
By the Exterior Angle Theorem:
(2x + 1) + 63 = 5x -2
2x + 64 = 5x - 2
66 = 3x
22 = x
Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:
5(22) - 2
110 - 2
108
The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)

x-2.5y=12.5
-x+2.3y=11.9
Answer: the answers are x = -292.5 and y = -122
Step-by-step explanation:
Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.
For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.
After that, we get the 2 equations as
2.3x-5.75y = 28.75
-2.5x+5.75y = 29.75
then by adding the 2 equations we get
-0.2x = 58.5
and by dividing 58.5 by -0.2 we get
x = -292.5
substituting the value of x in any equations above we get
y = -122

Answer:
x is 23
Step-by-step explanation:
cause it is an 180 angle so 180-93=87
87 -18 =69
3x=69
x=23
Answer:
x=23Step-by-step explanation:
in order to find x
(3x+18)° + 93°=180°
⇒3x+18=180-93
⇒3x=180-93-18
x=69/3
x=23
and there we go X = 23

Step-by-step explanation:
speed is determined by the gradient
car 1 gradient = change in y / change in x = [tex]\frac{85 - 75}{17 -15} = \frac{10}{2} = 5[/tex]
car 2 gradient = 10
so car 2 is travelling faster than car 1

Consider the table:

Which statements are true? Select all that apply.
The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.
Answer:
1st 2nd and 3rd box
Step-by-step explanation:
1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)
2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)
3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin
4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.

Answer:
3/5 1/10
Step-by-step explanation:
1/5 divided by 1/3 is 1/5 times 3 which is 3/5
1/2 divided by 5
= 1/2 divided by 5/1
=1/2 times 1/5
=1/10
Answer: 1) 3/5 2) 1/10
Step-by-step explanation:
1) 1/5 divided by 1/3
then you take the reciprocal so the equation is now 1/5 times 3/1
and you get an answer of 3/5
2) 1/2 divided 5/1 (you put the one under the 5 cuz it's a whole number)
Take the reciprocal of the second fraction and flip the numerator and denominator so you get 1/5.
Then, do 1/2 x 1/5 which equals 1/10.
Hope that helped! :)

Step-by-step explanation:
Answer:
66 2/3
Step-by-step explanation:
The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.
What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3
If i am wrong i'm sorry

when 2 pipes fill a pool together, they can finish in 5 hrs. if one of the pipes fills half the pool then the other takes over the finishes filling the pool, it will take them 18 hrs. how long will it take each pipe to fill the pool if it were working alone?
Answer:
about 10 hrs each id say
Step-by-step explanation:
I just did 5 times two
The time taken to fill the pool if it were working alone is 18 hours.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).
Given:
When 2 pipes fill a pool together, they can finish in 5 hrs,
One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs
1 / 2 of pool = 9 hrs as given
full pool = 9 × 2 = 18 hours
Therefore, The time taken to fill the pool if it were working alone is 18 hours.
