Answer:

A) A unit rate relates a quantity to 1 : TRUE

B) unit rates can be used to compare two rates : TRUE

C) any rate is equivalent to its unit rate

. FALSE

D) a unit rate always relates quantities with the same units. FALSE

Step-by-step explanation:

The ratio that which is used to compare quantities of different kinds is known as the rate of that quantity.

A unit rate is the ratio.

Number of units of the first type of quantity : Number of units of the second type of quantity.

Now,

A) a unit rate relates a quantity to 1.

TRUE, as a UNIT is equivalent to one.

Hence, unit rate unit rate relates a quantity to 1.

B) unit rates can be used to compare two rates

TRUE, unit rate compares two rates.

C) any rate is equivalent to its unit rate

FALSE, only the rate of one single unit is equivalent to its Unit Rate.

D) a unit rate always relates quantities with the same units

FALSE, rate compares the two terms which are in different units.

#1

That is false..one could have side lengths of 9 and 1, and the other could have side lengths of 3. Both the areas would be 9, but the figures would not be congruent.

#2

That is true, they must both have the same side length to have the same perimeter, therefore they will also have the same area.

What is the Lcm of 2 and 7

wel

Answer:

Step-by-step explanation:

The least common multiple is a number that both numbers can multiply something to get to, and the smallest possible common one.

Let's try listing out the multiples of 2:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

And the multiples of 7:

7, 14, 21, 28, 35, 42, 49, 56, 63, 70

Notice that both have the number 14 in common, and it is the first number that they do so. There are lots of other multiples that they have in common too, but 14 is the least.

Please help which should I choose

Aleksandr [31]

<h3>Answer: Choice A. Graph (1)</h3>

Reasoning:

If it is at all possible to draw a single vertical line through more than one point on the curve, then the graph is not a function. With graphs (2), (3) and (4), we can draw a vertical line through more than one point on those curves, so they aren't functions. Graph (1) is the only thing left. This graph is a function because it is not possible to draw a single vertical line through more than one point. It passes the vertical line test. Any input (x) leads to exactly one and only one y output.

Nice work on getting the correct answer when you chose "graph (1)".

How do I find the answer?

First simplify the number part, 14/2 = 7/1
then the x part, $\frac{x}{x^ \frac{3}{4} } = x^ \frac{1}{4} 
$
y doesn't need to be simplified
then simplify the z part, z^-6 = z^6

put it all together...
$7x^ \frac{1}{4}y^ \frac{1}{3} z^6$
