your answer.

Answers

Answer 1

Matter is anything that takes up space. All matter (aka everything) is made up of atoms. The air that we breathe is matter because it is made up of mainly oxygen atoms, but also other atoms as well. The air also takes up what we would call free space. A wooden desk is matter because it takes up space and is made of oxygen, carbon, nitrogen, calcium, and several other elements and atoms.

Answer 2
matter is anything that takes up space for example water (hydrogen2oxygen) takes up space in our bodies and air(oxygen) takes up space in our lungs

An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__

Answers

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

Answers

Answer:

A rotation or a reflection and a translation

Step-by-step explanation:

Ik I'm 2 years late but still.

The required angle of rotation is 180° and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

Given that,
To describe a sequence of translations, rotations, and reflections that take the lower left triangle to the upper right triangle.

What is congruent geometry?

Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.

Here,
To shift the lower left triangle to the upper right,
First It must rotate by an angle of rotation of 180° around the center of the geometry, Or it must reflect to the left diagonal.

Thus, the required angle of rotation is 180°, and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

–7.5 • (–2¾) and explain how you got the answer

Answers

Answer:

20.625

Step-by-step explanation:

I turned 3/4 into a decimal which would be .75 and then multiplyed -7.5 times -2.75 and then when you multiply 2 negatives you get a positive and then 2.75 times 7.5 is 20.625

1. Negative • Negative = Positive

-7.5 • (-2 3/4) = Positive


2. Turn (-2 3/4) into an improper fraction: (- 11/4) to multiply:

-7.5 • (- 11/4) = 20.625

EXTRA: “If you want, you can turn -7.5 into a fraction too if it helps you better!”
