How would you calculate the area and perimeter of 3yd 6yd 5yd 10yds
spayn [35]
Okay, start with the smaller square, you know the side length is 3 and that the width is 5, multiply this together:
3 * 5 = 15

That's the smaller left side of this shape, now the bigger side, divide the 10 yards at the bottom by 2 to properly represent the other side then multiply this by the 6 over there.
5 * 6 = 30

Conclusion for Area: After adding the results the answer should be 45.

The perimeter is solely adding all the sides together. You have a 10, two 5's, one 6, and two 3's. Add this together:

10 + 5 + 5 + 6 + 3 + 3 = 32

Conclusion for Perimeter: So the perimeter would be 32.

I hope this helps in someway, have a great rest of your day! ^ ^

Area of a right triangle is equal to (the length times the height) divided by 2

So the area of each tile is (3 x 3) / 2 = 4.5 square centimeters

200 tiles equal 200 x 4.5 = 900 sq cm

A scientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time.
irina1246 [14]

Answer:

C

Step-by-step explanation:

The easiest way to determine this is to realize that time is the independent variable (n) and temperature is the dependent variable (a).

From the table, we can plug in the two points (n) into n of each equation and see if that equals the temperature values (a).

<em>A little thinking would get us to plug the numbers in C first.</em>

<em>a(n)=46-(n-1)*4\\46-(5-1)*4=30</em>

<em>Works!!</em>

<em>Now, second number:</em>

<em>a(n)=46-(n-1)*4\\46-(6-1)*4=26</em>

<em>Works!!</em>

<em />

<em>Hence, C is the correct answer.</em>
