Why kilogram is more appropriate unit than milligram?

Step-by-step explanation:

that question is fundamentally wrong.

"appropriate" completely depends on the situation and circumstances.

if we are dealing with a weight that a human can feel, lift and distinguish from other weights without any special tool, then we are usually using kg. because then we humans can "connect" with the case, and deal with every day numbers.

if we are dealing with tiny little quantities like dosages of substances in a pill or other medication, then milligram is more than "appropriate".

because then, as humans, we are still dealing with numbers we can understand. like tens or hundreds.

if we kept kg in such situations, we would have to deal with numbers like 0.000008 kg vs. 0.000021 kg, where we could not see the magnitude of difference right away.

a display at an aquarium has sea stars to wolf eels in a ratio 4 : 5. It also has 5/8 as many rockfish as sea stars. there are 4

The number of sea stars is 64.

What is a ratio?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other.

In general, a: b, which can be interpreted as "a is to b," is used to denote a ratio between two quantities, let's say "a" and "b."

This ratio is expressed in fraction form as a/b. We utilize the same method for further simplifying a ratio as we use for further simplifying a fraction.

According to the question,

Ratio of sea stars to wolf eels = 4:5

Number of rock fish= 5/8 (Number of sea stars)

Number of wolf eels - Number of rock fish = 40

Using the given information, we get,

Number of sea stars = 8/5 (Number of rock fish)

On simplification,

Number of wolf eels = 80

So, number of sea stars = (4/5)*80

= 64

Answer:

64 degrees

Step-by-step explanation:

Since the triangles are similar they have the same angle measures

$\frac{PR}{PQ} =\frac{SU}{ST}$ $\frac{21}{14}= \frac{6}{4}$

∠P = ∠S ∠R =∠U ∠Q=∠T

We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U

In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula

$A+B+C=180$

$46+70+C+180$

$116+C=180$

subtract 116 from both sides

$C=64$

Therefore ∠Q is equal to 64 degrees

10 times as many as 1 hundred is hundreds or thousand

Paladinen [302]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

<h3>Further explanation</h3>

Consider the following sentence:

X times as many as Y refer to X multiplied by Y

Therefore, the phrase 10 times as many as 1 hundred is - can be rewritten to 10 multiplied by 100 is

We can say this is a simple multiplication operation, which is one of four basic operations, i.e.,

addition,
subtraction,
multiplication, and
division.

However, the case we face is only a multiplication, not accompanied by another operation.

Let's go back to our problem. We think naturally about this multiplication. 10 times 100 means there are two options like the following:

Addition of 10 as many as 100 times (there are 100 terms, this is too much written).
Addition of 100 as many as 10 times (there are 10 terms, still enough to be written).

Actually both are the same.

10 x 1 hundred = 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100 + 100

We state it quickly.

10 times as many as 1 hundred thousand is

10 x 1 hundred = 1 thousand, or

$\boxed{ \ 10 \times 100 = 1,000 \ }$

Based on present sources, the proper questions are as follows:

10 times as many as 1 hundred is __? __ hundreds or __? __ thousand.

Therefore, we rewrite the results in the unit form as requested.

10 times as many as 1 hundred is 10 hundred or 1 thousand.

Note:

The commutative property of multiplication: $\boxed{a \times b = b \times a}$
