Answer:

254/324 which is about 78.4%

Step-by-step explanation:

found area of entire square to be 18² or 324

found area of 4-quarter circles - which equals one circle with radius of 9

A = 81π which is about 70

subtracted 324 and 70 to get 254

ratio of shaded to unshaded is 254 : 324

Describe how you would find the third angle measure in a triangle knowing that one angle measures 63 degrees and the the other m
maxonik [38]

the missing angle is  c=69° .

<u>Step-by-step explanation:</u>

Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :

We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c  :

⇒ a+b+c=180

In question we have following parameters as :

a=63\\b=48\\c=?

Putting these value in  a+b+c=180 we get :

⇒  a+b+c=180

⇒  63+48+c=180

⇒  111+c=180

⇒  c=180-111

⇒  c=69°

Therefore , the missing angle is  c=69° .

Hey can you please help me posted picture of question
iragen [17]
We have the following function:
 C (t) = 6t - 180
 Clearing t we have:
 6t = c + 180
 t = c / 6 + 180/6
 Rewriting:
 t (c) = (c + 180) / 6
 Answer:
 
The inverse function for this case is given by:
 
t (c) = (c + 180) / 6

I need algebra help.....
Lubov Fominskaja [6]

Answer:

y=4(3)^x

Step-by-step explanation:

From the table given in the question,

x            y              Difference                  Ratio

1            12                     -                             -

2           36              36-12 = 24              \frac{36}{12}=3

3          108            108-36 = 72             \frac{108}{36}=3

4          324            324-108 = 216        \frac{324}{108}=3

5          972            972-324 = 648      \frac{648}{216}=3

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

y=a(b)^x

For a point (1, 12),

12=a(b)^1

ab=12 ------(1)

For another point of the table (2,36),

36=a(b)^2

ab^2=36 --------(2)

Equation (2) divided by equation (1)

\frac{ab^2}{ab}=\frac{36}{12}

b=3

From equation (1),

3a=12

a=4

Therefore, exponential function will be,

y=4(3)^x
