When you find a diameter of a circle, you probably used this formula:
C = $\pi$ d

If we algebraically manipulate the formula, we get it to find the diameter with a circumference.

Divide both sides by $\pi$ .

C / $\pi$ = $\pi$ d / $\pi$ .
$\frac{C}{ \pi }$ = d
d = $\frac{C}{ \pi }$

We know the circumference is 654 and we will use 3.14 for $\pi$ .

Plug in the values.

d = $\frac{654}{3.14}$
d ≈ <span>208.3

So, the diameter of the circle is about 208.3 units.</span>

Abby wants to use her savings of 1,325 to learn yoga. The total charges to learn yoga include a fixed registration fee of $35 an

NISA [10]

Answer:

Maximum number of months Abby can learn yoga is 25 months.

Step-by-step explanation:

We have given,

Total savings of Abby = $1325

Total charges to learn yoga is given as:

A fixed registration fee = $35

And a monthly fee = $50

Since the registration Abby pays only once. So we can calculate the remaining saving amount for Abby.

i.e Remaining saving amount after registration fee = $ (1325 - 35) = $1290

Now, from the remaining amount after paying registration fee , let the Abby learn yoga for x months.

To find maximum number of months we need to satisfy a equation given as:

$x*50 \leq 1290$

or $x\leq \frac{1290}{50} \\x\leq 25.8$

Since we got x ≤ 25.8 months ≈ 25 months (in integer form)

So maximum number of months Abby can learn yoga is 25 months.

What is the theoretical probability that you will get a sum of 7? P(sum of 7)=

hammer [34]

Answer:

$\frac{12}{36} or \frac{1}{3}$

Step-by-step explanation:

Notice that there are 6 sums of 7 on the table provided. For example rolling a 1 and then a 6 would produce a sum of 7.

The reason the answer is 12 and not 6 is that you need to double it for the two dice. Let's say one die was green and the other was blue. The green die could be the 1 and the blue die could be the 6. That is one favorable outcome, but it could be switched. Maybe the green die was 6 and the blue die was 1.
