<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

The total area of Ohio is 4.5 * 10^4 square miles.The total area of Ohio is about how many times the total area of Rhode Island?

Anon25 [30]

Answer:

The total area of Ohio is about 30 times the total area of Rhode Island

Step-by-step explanation:

Let

x -----> the total area of Ohio in square miles

y -----> the total area of Rhode Island in square miles

we know that

$x=4.5*10^{4}\ mi^{2}$

$y=1.5*10^{3}\ mi^{2}$ (searched in Google)

To find out approximately how many times the total area of Ohio is compared to the area of Rhode Island, divide the area of Ohio by the area of Rhode Island

$\frac{x}{y}$

substitute the values

$\frac{4.5*10^{4}}{1.5*10^{3}}=(\frac{4.5}{1.5})( 10^{4-3}) =3*10^{1}=30$

therefore

The total area of Ohio is about 30 times the total area of Rhode Island

Which value of k will make this relationship NOT a function? {(−7, 2), (−1, 0), (4, 8), (k, 0)}

ruslelena [56]

Answer:

In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.

Step-by-step explanation:

Requirement to be a function:

For a relationship to be a function, all values of x must have only one corresponding value of y.

In this question:

For x = -7, y = 2

For x = -1, y = 0

For x = 4, y = 0

For x = k, y = 0

A value of x must not have more than 1 value of y.

In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
