How many times larger is 3 x 1015 than 6 x 1010?
Final answer:
To find how many times larger 3 x [tex]10^{15}[/tex] is than 6 x [tex]10^{10}[/tex], divide the first by the second resulting in 5 x [tex]10^{4}[/tex]. This means 3 x [tex]10^{15}[/tex] is fifty thousand times larger than 6 x [tex]10^{10}[/tex].
Explanation:
To find out how many times larger 3 x [tex]10^{15}[/tex] is than 6 x [tex]10^{10}[/tex], you can divide the first number by the second number:
Write the division of the two numbers using scientific notation: (3 x [tex]10^{15}[/tex] ) / (6 x [tex]10^{10}[/tex]).Divide the coefficients (3 / 6) which equals 0.5.Simplify the powers of ten by subtracting the exponents ([tex]10^{15} / 10^{10}[/tex] becomes [tex]10^5[/tex]) because when you divide powers of ten, you subtract the exponents.Multiply the results of steps 2 and 3 together - [tex]0.5 * 10^5[/tex].Since 0.5 x 105 is equal to 5 x 104, 3 x [tex]10^{15}[/tex] is 5 x [tex]10^{4}[/tex] times larger than 6 x [tex]10^{10}[/tex].This means that 3 x [tex]10^{15}[/tex] is fifty thousand times larger than 6 x [tex]10^{10}[/tex].

John played a note on his tuba that vibrated the air 120 times per second. If you play the note for 4 seconds, how many times in the air vibrate?
480
This is this awnser because its 120 a second, for 4 seconds so 4 times 120 = 480.
Well the equation is rate*time=work/distance(in this case total vibrations)
Now we plug in the numbers:
(we know that 120 times per second is the rate because it uses the word per)
(4 seconds is the time because the unit is just seconds)
12*4=48*10=480
120*4=480
The answer is 480 vibrations

1. Tom and his best friend Edward are seeking to join a gym. Tom saw on television that Platinum Gym was having a grand opening in a few months. Tom is considering a membership at Platinum Gym. Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month. Tom's best friend Edward says he plans to join Super Fit because Super Fit only charges $10 a month but has a one-time registration fee of $150.
(a) Write an expression to represent the membership cost of Platinum Gym for x months.
(b) Write an expression to represent the membership cost of Super Fit for x months.
(c) If Tom decides to join Platinum Gym and Edward joins Super Fit, who would pay less during the first month of membership? Who would pay less after a year of membership? Show your work.
(d) Is there a membership period for which Tom and Edward would pay the same amount? If so, how long would this membership be and how much would it cost? Show your work.
(e) Which gym membership is a better deal? Explain why.
1.
Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month.
Super Fit charges a one-time registration fee of $150, and membership is $10 a month.
(a) Write a expression to represent the membership cost of Platinum Gym for x months.
Let x = months
20x + 60 is your expression
(b) Write an expression to represent the membership cost of Super Fit for x months
Let x = months
10x + 150 is your expression
(c) You are solving for both one month and twelve months of membership.
One month: Plug in 1 for x.
20(1) + 60 = 20 + 60 = 80
10(1) + 150 = 10 + 150 = 160
Platinum Gym is cheaper overall for one month by $80
One year: There are twelve months in a year. Plug in 12 for x.
20(12) + 60 = 240 + 60 = 300
10(12) + 150 = 120 + 150 = 270
Super Fit is cheaper than Platinum Gym overall for one year by $30
(d) Set the two expression equal to each other.
20x + 60 = 10x + 150
Isolate the x. Subtract 10x and 60 from both sides
20x (-10x) + 60 (-60) = 10x (-10x) + 150 (-60)
20x - 10x = 150 - 60
Simplify
20x - 10x = 150 - 60
10x = 90
Isolate the x. Divide 10 from both sides
10x/10 = 90/10
x = 9
It takes 9 months for the cost to be the same.
(e) It really depends on how long you want to work out at a gym. If you are working out for less than a year, than Platinum Gym is the better choice. If more than a year, then Super Fit is the better choice.

Which of the following is an example of a chemical change?
Select one:
a. The shell of an egg breaks when it is struck against a hard surface.
b. A mixture of flour, sugar, eggs, and butter is baked to become a cake.
c. Flour and sugar are sifted together into a measuring cup.
d. Chocolate squares are melted to make cake icing.
The answer is B.
To find the answer you can immediately cross out A and C. You're left with a mixture of ingredients that turn into a cake or choclate melting. Chocolate melting is a physical change so by using the process of elimination you can conclude that B is the correct answer.
Answer:
The correct answer is option B.
Step-by-step explanation:
We call chemical change to the process where two or more substances are transformed into other substances.
During this change, the substances will have a modification in the structure of their molecules and their bonds.
In the case of the example we can see how different substances (flour, sugar, eggs and butter) will change the shape of their structure to form another substance: the cake. This cake will receive the name of product.
Given this information, we can say that the correct answer is option B.
If 13% of the 250 million adult Americans live in poverty, how many adult Americans live in poverty?
If 13% of 100 is 13, than 13% of 100 million is 13 million. And multiplying two on both sides, we get that 13% of 200 million is 26 million. If we take it the other way, we get that 13% of 50 million is 6.5 million. As 6.5 million + 25 million is 31.5 million, this is our answer.
your answer is 32,500,000

Find a number whose product with six is the same as its sum with 45
1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.
identify the slope and y-intercept of this equation and then show the steps to convert to standard form
y=9x+7
The slope is the factor in front of x, so slope is 9.
The y intercept is 7 (that's the point of cross the y axis, where x=0)
There are multiple definitions of "standard form" for lines, so here are the two i can think of:
9x - y = -7 (the implicit function form)
or
y-7 = 9*(x-0) (the point-slope form)

The sum of two numbers is 12 the difference of the same is -4 formulate a system of equation and find the number
Answer:
The numbers are a= 4 and b= 8.
Step-by-step explanation:
Let the unknowns number be a and b.
assume a>b.
As per the given condition: The sum of two number is 12 and the difference of the same is -4.
from the above conditions we have:
[tex]a+b =12[/tex] ......[1]
[tex]a-b=-4[/tex] ......[2]
Now, adding equations, we will eliminate b leaving an equation in a that we can solve:
⇒ [1]+[2] gives;
[tex](a+b)+(a-b)=12+(-4)[/tex] or
[tex]a+b+a-b=12-4[/tex]
Simplify:
[tex]2a=8[/tex]
Divide by 2 on both sides, we get
[tex]\frac{2a}{2}= \frac{8}{2}[/tex]
Simplify:
a=4
Substitute the value of a= 4 in equation [1] . to solve for b;
[tex]4+b=12[/tex] or
b= 12-4 =8
Therefore, the numbers a and b are 4 and 8

What is 2.26 (26 repeating)as a fraction
The repeating decimal 2.26 (with 26 repeating) is converted to a fraction by setting it as 'x', scaling by 100, subtracting the original x, and then simplifying to get the fraction 224/99.
To convert the repeating decimal 2.26 (with 26 repeating) to a fraction, we use the following steps:
Let x = 2.262626..., which is the number we want to express as a fraction.Multiply x by 100 (since the repeating part is two digits long), so 100x = 226.262626....Subtract the original number x from this new number, so 100x - x = 226.262626... - 2.262626..., which gives us 99x = 224.Now, divide both sides by 99 to solve for x. Therefore, x = 224 / 99.We now have our fraction, which is 224/99.

(a) 2x + 3x - 6 = 10 + 4x ---> Answer: x = 16, it has one solution, it is an identity.
Adding the like terms on the same side of the equation to solve for x:
2x + 3x - 4x = 10 + 6
x = 16
(b) 17 + 5x = 23 + 4x - 6 + x ---> Answer: it has infinite number of solutions, it is a contradiction
Adding the like terms on the same side of the equation to solve for x:
5x - 4x - x = 23 - 17 - 6
5x - 5x = 6 - 6 (this equation is cancelling everything on each side so it can not be true no matter what value we assign, therefore it has infinite number of solution)
(c) 7x + 4 = 5x + 8 + 2x - 10 ---> Answer: no solution, its a contradiction.
Adding the like terms on the same side of the equation to solve for x:
7x - 5x - 2x = -10 + 8 - 4
7x - 7x = -6 (the terms of x are cancelled by each other, therefore no solution.
