What is the value of the expression? 3(6/8−1/2)+0.25

Answers

Answer 1

If I am correct the answer is 1.
You can do multiply 3 by 6/8 which will give you 2 1/4 or if in a decimal 2.25.
Then do 3 by -1/2 which will give you -1 1/2 and in decimal its -1.5.
You continue with the equation, 2.25 -1.5 = 0.75 + 0.25 = 1
Add them all together and you get 1...!

Hope this Helps :)

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.

16 - 2t = 5t + 9

What number does t represent? I'm bored

Answers

Try not to be bored. You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.

t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.

To find this value, do the following: Add 2t to both sides, and then subtract 9 from both sides. You'll end up with 7t = 7, which yields t = 1.

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.

The answer is D = 8 . You have to subtract 4d from one side and what you do to one side you must do to the other. Then you end up with 5d-5=35. You would add 5 to both sides and get 5d=40. then you divide 5 into both sides and you would get 8 :D

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

what is the square root of negative 100

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).

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.
