Mathematics

5 0

Answer:

201.06 or 200.96

Step-by-step explanation:

Use the first answer if you were asked to answer with π and use the second one if you were asked to use 3.14 if your teacher didn't specify use the first one.

To find the area of a circle you use π r² or π multiplied by the radius squared the diameter (which is what we are given) in this case is 16" so you would divide it by two giving you 8 then square 8 giving you 64 and then do π64 or π(8²). A way my teacher helped us learn these equations is with a really cool song, its called The Circle Song look it up online, I hope it helps!

Which statement describes the relationships between x and y in these two equations?
Maru [420]
B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.

Out of all the answer choices, b makes the most sense.

25x can be translated as 25 times x.

x + 25 can be translated as 25 more than a number.



Hope this helps!

How do i solve this?
vovikov84 [41]

Answer:

x = 4

y = 9

Step-by-step explanation:

It is given that figure (NPQR) is a square. One property of a square is that all sides of a square are congruent. This property also applies to the given square, thus one can make the following statement;

PQ = NR

Substitute,

10y - 29 = 5y + 16

Inverse operations,

10y - 29 = 5y + 16

-5y           -5y

5y - 29 = 16

    +29   +29

5y = 45

/5     /5

y = 9

Another property of a square is that all of the interior angles of a square have a measure of (90) degrees. Moreover, the diagonals (segment connect non-adjacent vertices) bisect these angles. Thus, twice the measure of an angle formed between a side and a diagonal forms a (90) degree angle. Therefore, one can draw the following conclusion;

2(m<QPR) = 90

Substitute,

2(6x + 21) = 90

Simplify,

12x + 42 = 90

Inverse operations,

12x + 42 = 90

        -42  -42

12x = 48

/12     /12

x = 4
