How does a sequence of translations, reflections, and rotations result in congruent figures?

Mathematics

Answer:

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

Step-by-step explanation:

It takes a person the same time to walk 10 miles as it takes a car to travel 15 miles in heavy traffic. If the car is traveling
storchak [24]

The person is traveling 30 mph.

The car is traveling 45 mph.

Just mulitply 15 x 3 and 10 x 3.

Let’s break the numbers down.

10 + 5 = 15. So we can break 15 down like how you add 15.

10 x 3 = 30.

5 x 3 = 15.

Let’s add 30 and 15 together.

30 + 15 = 45.

Let’s now multiply 10 and 3.

10 x 3 = 30.

Ratioz rate unit rate <br>I have a quiz tmr 7th grade I need to learn ratio, rate unit rates!!! ​
posledela

Alright! I'll help you. Let me tell you what's ratio, rate unit rates all about! :D

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the difference between a unit rate and a ratio?

Guide the discussion so that students understand that a ratio is simply the quotient of two numbers, while a rate is the ratio of two measurements that have different units (like miles and hours, or dollars and ounces). Reinforce the fact that a rate is usually expressed in per unit form, where the denominator is 1.

What are some examples of ratios?

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

Is a rate always a ratio?

Rates and ratios. ... A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.

How do I find the unit rate?

To get the unit to equal 1, divide both numbers by the denominator; your answer is the number you get by dividing the numerator by the denominator. Use this method to calculate unit cost, too—you're calculating how much 1 item is worth, after you're given the amount that multiple items cost.

Here are some questions and how to answer them to help you! I hope this helps you! c:
