What is the least common denominator of 1/3 and 3/5?

62 POINTS AND BRAINLIEST PLS HELP

Answers

Answer 1
Multiply the denominators 3 and 5 to get 3*5 = 15

Divide the result over 1 since 1 is the GCF of 3 and 5
15/1 = 15

Therefore the lowest common denominator (LCD) is 15

Answer: 15

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks:

Answers

Solve for x:2 (x + 3) - 8 = 0
2 (x + 3) = 2 x + 6:
2 x + 6 - 8 = 0
Grouping like terms, 2 x - 8 + 6 = 2 x + (6 - 8):
2 x + (6 - 8) = 0
6 - 8 = -2:
2 x + -2 = 0
Add 2 to both sides:
2 x + (2 - 2) = 2
2 - 2 = 0:
2 x = 2
Divide both sides of 2 x = 2 by 2:
(2 x)/2 = 2/2
2/2 = 1:
x = 2/2
2/2 = 1:
Answer: x = 1

Estimate to the new integer I don't understand help 23 and 25 I'm.not sure this is right

Answers

Integers is a number without a decimal point.

To do this we need to find the two perfect squares in between 23.5, which are 16 and 25. Since 23.5 is closest to 25, your answer is √25, or 5.

Doing this on the second one, We need to find the perfect cube roots that have 430 in between. It is 343 and 512. Since 430 is closer to 343, your answer is the cube root of 343, or 7.

Hope this helps!
Hello There!

An integer is a whole number.
√23.5 = 4.84767985742.
As an integer this would be 5 or √25.
The second one is ∛343 or 7.

Hope This Helps You!
Good Luck :)

36/8 as a mixed number, in simplified form

Answers

36/8 as a mixed number in simplest form is 4 4/8. To turn improper fractions into mixed numbers, divide the numerator by the denominator, (in this case it's 36 ÷ 8), then the answer will be the whole number part, and the remainder will be the numerator.

If 5/8 of the people in water aerobics class are over age 65 and 1/4 of the people in the class are under age 40,what fraction of the people in the class are either over 65 or under 40?

Answers

I think the answer's 7/8. If you convert 1/4 to 2/8 and add them together, you add 5/8 and 2/8 to get 7/8. 
Final answer:

To find the fraction of people in the class who are either over 65 or under 40, we add the fractions of people in each age group. The maximum fraction is 1.

Explanation:

To find the fraction of people in the class who are either over 65 or under 40, we need to add the fractions of people in each age group. First, we find the fraction of people over 65 by multiplying the total fraction by the fraction of people over 65: 5/8 * 1 = 5/8. Next, we find the fraction of people under 40 by multiplying the total fraction by the fraction of people under 40: 1/4 * 1 = 1/4. Finally, we add the two fractions together to find the total fraction of people who are either over 65 or under 40: 5/8 + 1/4 = 9/8. However, fractions cannot be greater than 1, so the maximum fraction is 1. Therefore, the fraction of people in the class who are either over 65 or under 40 is 1.

PLEASE HELP! there are multiple answers. Juan has a budge of $20.00 for lunch each week. Choose one of the meals from the part b for juan's lunch on monday ( I chose hamburger which is $2.50).

what is the square root of negative 100

Answers

What is the square root of negative 100
√-100 = 10i or -10i

Hello, let's say that a negative square root gives a result that is NOT a real number. A negative number is not a square (a negative number squared gives always a positive number).

Thus, they can be represented with an "i", the immaginary unit.

So, the solution would be -10i (because, as I said, there isn't a real negative number that squared gives -100).

Can someone please solve this:

(a+b)2 - (a-b)2= (they are in square)


note: I know the formula but I don't understand hownu factorize it like why that way, if u want please explain it

Answers

(a+b)^2 – (a-b)^2

Since both are squares you end up with

(a+b +a-b) * (a+b –(a-b))

 

First set of parenthesis add the 2 a’s together to get 2a and subtract b from b

 So you end you with 2a

 Now you have

2a(a+b –(a-b))

Second set of parenthesis you subtract a from a and then have b+b left which equals 2b

 So now you have 2a times 2b

 Which equals 4ab

Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay Francine got 34 multiple choice questions correct I received 14 points for her essay Cheryl got 30 multiple choice questions correct I received 22 point for her outside how many points with each multiple-choice?

Answers

the answer should be 2

You can solve this problem using this equation: 34x + 14 = 30x + 22. The x stands for how many points each multiple choice question is worth. 34x is the number of multiple choice questions Francine got correct multiplied by the currently unknown number each point is worth, while 14 represents the 14 points that Francine was given for her essay. 30x is the number of multiple choice questions Cheryl got correct multiplied by the currently unknown number each point is worth, while 22 represents the 22 points that Cheryl was given for her essay. To solve, we can subtract 30x from 34x on the left side of the equation, and subtract 14 from 22 on the right side of the equation. That leaves, 4x = 8. Next step would be dividing 4 from each side which gives us x = 2. In order for Francine and Cheryl to receive the same test score, each multiple choice questions would have to be worth 2 points.

The particle of dust has a mass of 7.53x10 to the-10 kilograms. Find the weight of 5 billion dust particles

Answers

It would be 3.765 pounds. You have to do 7.53 x 10 to the -10= 0.000000000753. Then do 0.000000000753 x 5 billion to get 3.765.

Final answer:

To find the weight of 5 billion dust particles, multiply the weight of one particle (determined by the mass of the particle times gravity) by 5 billion. The resulting weight of these dust particles is approximately 36.9 Newtons.

Explanation:

The weight of a particle can be determined using the formula weight = mass x gravity. Given that the mass of a dust particle is 7.53x10^-10 kilograms and assuming normal earth gravity which is approximately 9.8 meters per second squared, the weight of one dust particle is about 7.38x10^-9 Newtons. If we want to find the weight of 5 billion such particles, we'd multiply this single particle weight by 5 billion (5x10^9), resulting in a total weight of about 36.9 Newtons.

17.) Rachel is planning a wedding for 100 to 250 people, depending on costs. She has hired a caterer that charges $20 per person, plus a flat fee of $200.

a.) Write an inequality in terms of p people that describes how many people Rachel plans to invite.

b.) Adjust that inequality to show how much the caterer will charge in terms of p.

c.) What is the range of catering fees that Rachel is considering?

Answers

Part A:

Given that Rachel is planning a wedding for 100 to 250 people, the inequality in terms of p people that describes how many people Rachel plans to invite is given by:

100 ≤ p ≤ 250



Part B:

Given that the caterer charges $20 per person, plus a flat fee of $200, the inequality that shows how much the caterer will charge in terms of p is given by:

20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200



Part C:

The range of catering fees (C) that Rachel is considering is given by:

20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200

2000 + 200 ≤ C ≤ 5000 + 200

2200 ≤ C ≤ 5200

Therefore, the range of catering fees Racheal is considering is from $2,200 to $5,200
