Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
You can identify in the figure that:

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

Now you must simplify and solve for "z"

Finally, substituting the value of "z" into
, you get:

Answer:
A) m∠3 + m∠4 = 180
Step-by-step explanation:
Both angles make a straight line which has an angle of 180.
Take the root of both sides of the equation.
y = ^3 √64
Calculate the root.
y = 4
In the end, when you substitute y for 4,
4^3 will get you 64.
Base 10 blocks are used to perform arithmetic operations.
To model the product of 3 and 0.51, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>
The expression can be represented as:

Express 0.51 as 0.5 + 0.01

- 0.5 means 5 tenths
- 0.01 means 1 hundredths
- 3 means that, the above blocks are needed in three places.
Hence, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>

Answer:
Average grade for this test = 1.85
Step-by-step explanation:
Given that number of students receiving respective grade scores are : 11, 18, 52, 13, 6
Then total number of students = 11 + 18 + 52 + 13 + 6 = 100
Sum score obtained by total students
= 11F + 18D + 52C + 13B + 6A
= 11(0) + 18(1) + 52(2) + 13(3) + 6(4)
= 0 + 18 + 104 + 39 + 24
= 185
Now average grade for this test is given by 185/100 = 1.85
Hence final answer is 1.85.
