Answer:

75.7m^2

Step-by-step explanation:

\frac{30}{360}  \times \pi {r}^{2}  \\  \frac{30}{360}  \times  \frac{22}{7}  \times  {17}^{2}  \\  \frac{1}{12}  \times  \frac{22}{7}  \times 289 \\ 75.6904761905 = 75.7

Answer:

Hey there,

(It would be good to note that i just learned how to simplify/solve algebraic expretions)

P=21+2w

P/21=2w

then we flip it

2w=p/21 which could also be

w=2(p/21) i think

What is the decay factor of the exponential function<br> represented by the table?
bulgar [2K]

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

y=ab^x              ...(i)

Where, a is the initial value and 0 is the decay factor and b>1 is the growth factor.

The exponential function passes through the point (0,6). Substituting x=0,y=6 in (i), we get

6=ab^0

6=a(1)

6=a

The exponential function passes through the point (1,2). Substituting x=1,y=2,a=6 in (i), we get

2=6(b)^1

2=6b

\dfrac{2}{6}=b

\dfrac{1}{3}=b

Here, b=\dfrac{1}{3} lies between 0 and 1. Therefore, the decay factor of the given exponential function is \dfrac{1}{3}.

Hence, the correct option is A.

Three ounces of cinnamon cost 2.40. If there are 16 ounces in 1 pound, how much does cinnamon cost per pound?
BartSMP [9]
To find how much cinnamon per pound you first divide the $2.40 by the 3 oz to find how much per ounce...so $2.40/3 = 80 cents. Then u multiply that by the 16 oz to get the amount for 1 pound...so .80x16= $12.80 per pound.
Hope it helps!
