1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded

2) c, e, and f

Olve for x. 3(3x - 1) + 2(3 - x) = 0 x = 3/7 x = -3/7 x = 1/3 x = -1/3

zloy xaker [14]

<u>Answer:</u>

x = -3/7

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

We are given the following equation for which we have to solve for x:

$3(3x - 1) + 2(3 - x) = 0$

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

$9x-3+6-2x=0$

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

$9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}$

Therefore, x = -3/7.

Which expression is equivalent to (One-sixteenth) Superscript negative 4?

Bumek [7]

Answer:

65,536

Step-by-step explanation:

Since there are no options, I would simply simplify the expression given.

One-sixteenth= $\frac{1}{16}$

We want to determine an equivalent expression to $(\frac{1}{16})^{-4}$

Now, from laws of indices (i) $a^{-1}=\frac{1}{a}$ (ii) $a^{mn}=(a^m)^n$

Therefore applying Rule (ii) above: $(\frac{1}{16})^{-4}$ = $(\dfrac{1}{16})^{-1X4}=[(\dfrac{1}{16})^{-1}]^4$

Using Rile (i),

$(\dfrac{1}{16})^{-1}=\dfrac{1}{\dfrac{1}{16}}=16$

Therefore $[(\dfrac{1}{16})^{-1}]^4 =16^4=65536$
