Answer:

Their atomic theory of the elements

Step-by-step explanation:

The ancient Greeks believed that all matter consisted of four elements — earth, air, fire, and water

Everything on Earth consisted of these elements in different combinations.

Robert Boyle is best known for his famous Law — p₁V₁ = p₂V₂.

However, he was also an excellent chemist who did many experiments.

He found it was impossible to combine the four Greek elements into any substance.

Boyle found he could decompose many substances into simpler substances, but none of them was a Greek element.

He therefore rejected the Greek theory.

Almost 150 years before Dalton's atomic theory, Boyle proposed a new definition of an element:

An element is any substance that cannot be broken into a simpler substance.

Which expression is equivalent to r^m ÷ r^n?

Andre45 [30]

R^m ÷ r^n is equal to r^(m-n).

For example, 2^5 <span>÷ 2^3 = 2^2.

Is that what you mean?

5.35*2+x=16

10.70+x=16

-10.70 -10.70

x=5.30

Ted is making a bread recipe that uses three 1/4 cups of flour and a muffin recipe that uses 2 3/4 cups of flour eggs. How much

wlad13 [49]

Amount of flour used in bread recipe = $3 \frac{1}{4}$ cups

Amount of flour used in muffin recipe = $2 \frac{3}{4}$ cups

We have to determine how much more flour is in the recipe.

Since, more amount of flour is used in bread recipe than in muffin recipe.

Total amount of more flour = $3 \frac{1}{4} - 2 \frac{3}{4}$

= $\frac{13}{4} - \frac{11}{4}$

= $\frac{2}{4}$

= $\frac{1}{2}$

Therefore, $\frac{1}{2}$ more cup of flour is used in bread recipe than in muffin recipe.

Now, we will determine the total amount of flour used in both recipe.

Total amount of flour used in bread and muffin recipe

= $3 \frac{1}{4} + 2 \frac{3}{4}$

= $\frac{13}{4} + \frac{11}{4}$

= $\frac{24}{4}$

= 6 cups

Therefore, total 6 cups of flour are used in both the recipes.
