What is a unit rate?

1 answer:

3 0

A unit rate can be represented as"The number of x's per 1." They are often given in scenarios of several days, and you need to calculate what happened in 1 day.

For example:
John sells 60 watermelons in 30 day. What is the unit rate of his sells?

If he sells 60 in 30 days, that means he sells 2 watermelons per day. Therefore, the unit rate is 2.

Which term is correct when simplifying √128? A.) 16 B.) 12 C.) 10 D.) 8√2

alina1380 [7]

When dealing with roots, we want to factor to see if it's possible

$128 = 2 \times 64$
$= 2 \times 2 \times 32$
$= 2 \times 2 \times 2 \times 16$
$= 2 \times 2 \times 2 \times 2 \times 8$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 4$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$

now since we're dealing with square roots, we circle every pair of numbers we see in the final factoring
so..
$= (2 \times 2) \times (2 \times 2) \times (2 \times 2) \times 2$

now for every circled pair, we take only 1 of the 2 circled and bring it outside
anything left uncircled stays inside the root
so..
$= 2 \times 2 \times 2 \times \sqrt{2}$

now simply multiply
$8 \sqrt{2}$

Describe what happens when two intersecting lines form a linear pair of congruent angles. Explain how you can get eight congruen

Charra [1.4K]

The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.
