(B) The price is 150% of the price before
(C) The price was reduced by a quarter
(D) The price became a half of what it was before
(E) The price is now 1.5 of what it was before

(G) The price now is 200% of what it was before
(H) The price is 75% of what it was before
Plssss help me!!
Answers
(A) The price doubled
(G) The price now is 200% of what it was before
Explanation:
Assume that the original price of the product is x. Therefore, x represents 100% of the original price.
Now, we are given that:
The price increased by 100%
This means that:
new price = old price + 100% of old price
new price = x + 100% (x)
new price = 2x
Thus, we can note that the price is doubled
We know that x represents 100% of the price of the product.
Therefore:
new price = x + x = 100% + 100% = 200%
This means that the new price is 200% of the old price
Notes:
Options C,D, F and H are incorrect because they represent a decrease in the price while we know that the price increased
Options B and E are incorrect because they represent an increase of 50% in the price while we know that the increase is 100%
Hope this helps :)
Answer:
A G
Step-by-step explanation:
because when the price is doubled that means it increases by 100%
and when the price is 200% of what it was befor means it is also doubled

A spherical balloon is inflated until its diameter is 24 in. Air is then released from the balloon until its diameter is 18 in. Approximately many cubic inches of air were released from the balloon?
formula: V =4π(r^3)/3 **make sure you use the radius and not the diameter**
Answers
amount of air released = 4184.6 in³
Explanation:
We can get the volume of released air by calculating the difference between the volume of the balloon before and after the air was released. This difference will represent the amount of released air.
Initial volume of balloon:
V = [tex] \frac{4}{3} [/tex]πr³
We have diameter = 24 in
Therefore:
radius = 24/2 = 12 in
volume = [tex] \frac{4}{3} [/tex]π(12)³
initial volume = 2304π in³
Final volume of balloon:
V = [tex] \frac{4}{3} [/tex]πr³
We have diameter = 18 in
Therefore:
radius = 18/2 = 9 in
volume = [tex] \frac{4}{3} [/tex]π(9)³
final volume = 972π in³
Amount of air released:
amount of air released = initial volume - final volume
amount of air released = 2304π - 972π
amount of air released = 1332π = 4184.6 in³

What is Exponential Form?The exponential form is an easier way of writing repeated multiplication involving base and exponents. It has a base and a power
The exponential form of a number is a way of representing a number using exponents, where the base is typically a number greater than 1.
It is often used in mathematics and science to represent large or small numbers more efficiently. It can also be used to simplify certain mathematical operations, such as multiplication and division, by using the properties of exponents.
Given data ,
Let the exponential form of the number be A
Now , the value of A = 9.03×10²
To convert 9.03×10² to standard form, we need to multiply the number by the appropriate power of 10 so that it is expressed as a number between 1 and 10.
Starting with 9.03×10² , we can move the decimal point two places to the right to get:
9.03×10^2 = 903
So the standard form of 9.03×10² is simply 903

solve for K. I TRIED MANY TIMES TO GET IT RIGHT BUT I STILL GET STUCK WHEN I AM CLOSE TO FINDING THE ANSWER!!!!
m=1/k+n

This is how you would solve for k.
m(k + n) = 1
k + n =[tex] \frac{1}{m} [/tex]
k = [tex] \frac{1}{m} [/tex] - n
[tex]m=\frac{1}{k}+n[/tex]
We need to solve for k.
In order to solve for k, we need to isolate k, meaning
1. subtract n on both sides in order to isolate k, simplify
[tex]m=\frac{1}{k}+n[/tex]
[tex]m-n=\frac{1}{k}+n-n[/tex]
[tex]m-n=\frac{1}{k}[/tex]
2. multiply k on both sides, do not forget the parentheses,

How many liters of a 10% saline solution must be added to to 4 liters of a 40% saline solution to obtain a 15% saline solution? A)20 L B)4 L C)2 L D)48 L Plz explain the steps and how to get answer
Answers
We will let x be the amount of 10% solution in our problem. 10% saline in x liters is 0.1x. 4 liters of a 40% solution would be 4*0.4 = 1.6. We know that there are a total of x+4 liters in the final solution, and that it is 15% saline; that is 0.15(x+4). Our equation is then:
0.1x + 0.4(4) = 0.15(x+4)
0.1x+1.6 = 0.15*x + 0.15*4
0.1x+1.6 = 0.15x+0.6
We cannot have a variable on both sides; we will subtract 0.1x from both sides:
0.1x + 1.6 - 0.1x = 0.15x + 0.6 - 0.1x
1.6 = 0.05x + 0.6
Subtract 0.6 from both sides:
1.6 - 0.6 = 0.05x + 0.6 - 0.6
1 = 0.05x
Divide both sides by 0.05:
1/0.05 = 0.05x/0.05
20 = x
x was the 10% solution, so there are 20 liters of it.

In one city, 3,546 people attended a concert but in another city, 9,238 people attended the same band's concert. Estimate how many more people attended the concert in the second city by rounding to the nearest hundred and then subtracting.
Answers
Approximately 5,700 more people attended the concert in the second city.
To estimate how many more people attended the concert in the second city, we can round the attendance numbers to the nearest hundred and then subtract the smaller number from the larger one. For the first city, 3,546 people rounds off to 3,500 people, and for the second city, 9,238 people rounds off to 9,200 people. Now we subtract the rounded number of the first city from the rounded number of the second city.
So, 9,200 (rounded attendance in the second city) minus 3,500 (rounded attendance in the first city) equals 5,700.
Therefore, approximately 5,700 more people attended the concert in the second city.

emma drives 1/4 of the way to work and uses 1/9 gallon of gas what fraction of the distance can she drive to work which one gallon of gas?
Answers
Emma can drive 1/4 of the distance to work with one gallon of gas.
Explanation:To find out what fraction of the distance Emma can drive to work with one gallon of gas, we need to find the fraction of the distance she can drive with 1/9 gallon of gas and then multiply it by the number of gallons in one gallon.
Emma drives 1/4 of the way to work and uses 1/9 gallon of gas. So, she can drive 1/4 * 1/9 = 1/36 of the distance to work with 1/9 gallon of gas.
To find the fraction of the distance she can drive with one gallon of gas, we multiply 1/36 by the number of gallons in one gallon: 1/36 * 9/1 = 9/36 = 1/4.
Therefore, Emma can drive 1/4 of the distance to work with one gallon of gas.

If a term in the sequence is even, then the next term will be half the value of that term. If a term in the sequence is odd, then the next term in the sequence is one more than three times that term. By following these rules, the first three terms of this sequence are 26, 13 and 40. Is the twenty-sixth term of the sequence odd or even. Justify your answer.

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A line plot shows the frequency of data, in short it shows how many times something has occurred or the number of times data occurs in a group of data.
The number of data is represented by markers or in this case "x"s. The more x's along the column, the more times it occurred.
The bar graph there does not show the frequency of the different scores. This shows the relationship between the test number and the percentage of the scores obtained. It does not tell you the individual scores obtained.
The least common test score is 70

Answers
Answer:
A and C
Step-by-step explanation:
Two different ways of factoring -3x - 9 are:
A. -3(x + 3)
C. 3(-x - 3)
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.
To factor -3x - 9, we can rewrite it as -3(x + 3) or 3(-x - 3).
Both of these expressions are in the form of a product of a constant and a binomial (a polynomial with two terms).
Option A, -3(x + 3), can be obtained by applying the distributive property, which states that we can multiply a constant by each term in a binomial to obtain the product.
In this case, we have -3 × x + -3 × 3 = -3x - 9.
Option C, 3(-x - 3), can also be obtained using the distributive property. In this case, we have 3 × -x + 3 ×-3 = -3x - 9.
Option B, 3(x + 3), is incorrect because the coefficient of the x term is positive, whereas in the original expression it is negative.
Option D, -3(x - 3), is also incorrect because the coefficient of the x term is negative, whereas in the original expression it is positive.
