72-(63-8) and (72-63)-8

Answers

The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.

For the first one you get:
72 - (63-8)
72 - 55
17

For the second one you get:
(72-63)-8
9-8
1

Which mean that The 2 equations are not equal, because 17 \ \textgreater \ 1
Hope this Helps! :D
They are not equal because for each you get different answer.

72-(63-8) \n 72-55 \n 17

(72-63)-8 \n 9-8 \n 1

17 and 1 are not equal.

Therefore, the two expressions  72-(63-8) and (72-63)-8 are not equal .

U^-3=1/125
U=?

Answers

a^(-n)=(1)/(a^3)\n-----------------------\n\nU^(-3)=(1)/(U^3)\n\ntherefore\n\n(1)/(U^3)=(1)/(125)\ \ \ \ \ |inverse\ both\ sides\n\nU^3=125\n\nU=\sqrt[3]{125}\n\n\boxed{U=5}\ because\ 5^3=125
the answer is: U =5

first, you take the U^-3 and put it as 1/U^3, that is because you cannot have a negative exponent, you MUST turn the exponent into a positive....
now you have 1/U^3 = 1/125...     now you find the uncubed version of 125::::::

the cube root of 125 is 5

so, when you have U^-3, you are looking at 5^-3..   

How many diagonals does a triangular prism have?

Answers

The number of diagonals that the triangular prism will have is 6.

What is a triangular prism?

Suppose you've got a triangle. Now, stretch it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.

Usually, when we talk about a triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.

Since a triangularprism is made up of 2 triangles and 3 rectangles. Also, a triangle has no diagonals while a rectangle has 2 diagonals. Therefore, the number of diagonals, the triangular prism will have is,

Number of diagonal

= Number of diagonals on triangles + Number of diagonals on rectangles

= (2×0) + (3×2)

= 6

Hence, the number of diagonals that the triangular prism will have is 6.

Which expression is equivalent to |a| < 3?1. A ≥ -3 and a ≤ 3
2. A ≤ -3 and a ≥ 3
3. a ≥ -3 or a ≤ 3
4. A ≤ -3 or a ≥ 3

This question is worth 40 points. Please help im struggling with this answer!

Answers

Answer:

1. a ≥ -3 and a ≤ 3

I am assuming you mean to have an = sign as well

Step-by-step explanation:

|a| < =3

we get two solutions, one positive and one negative

remember to flip the inequality for the negative

a<=3 and a >= -3

Students in Miss Moseley's fourth grade class are learning multiplication, and they demonstrate mastery by passing assessments. Travis has passed 11 tests, and his classmate, Jenifer, has passed 2 tests. Going forward, Travis plans to pass 2 tests per week. Meanwhile, Jenifer plans to pass 5 tests per week. Eventually Jenifer will catch up to Travis. When the number of tests each student has passed are equal, how many tests will each student have passed and how many weeks will it take?
