The answer is actually D because 7 and 35 divided by 7 are 1 and 5.

Answer:

$\frac{1}{5} ;\frac{2}{10} ;\frac{3}{15}$

Step-by-step explanation:

To find the three ratios we only have to find the most simple ratio of $\frac{7}{35}$ , and then find the other ratios that are equal to it.

So, $\frac{7}{35} = \frac{1}{5}$

Also, $\frac{1}{5} =\frac{2}{10}$ , by multiplying by two each part of the fraction.

Similarly, $\frac{3}{15} = \frac{1}{5}$ , by multiplying by three.

Therefore, comparing all these ratios, all are the same, they are equal to $\frac{1}{5}$ . So, the option that correctly has these choices is D.

Answer:

Ф = ------------ = 7/5 radians

Step-by-step explanation:

"e" is inappropriate format here. Use Ф or α or similiar character for central angle.

Here, (arc length) = (radius)(central angle), or s = rФ, and so:

(central angle) = Ф = (arc length) / (radius)

7 ft

Here, Ф = ------------ = 7/5 radians

5 ft

48p=1200

p=25%

Please help I am very confused on what to do.

The question is asking to make facts about the graph. Do you see any domain,range, maximum or minimum, etc. you didn’t add the graph. So remember that
Domain is all possible input (x) values
Range is all possible output (y) values
Function is the x-values can NOT repeat.
