If this is using transversals, and they are in fact a linear pair, then the answer would be 180-113= 67

If its not a transversal, let me know!

The goals against average (A) for a professional hockey goalie is determined using the formula A = 60 a equals 60 left-parenthes

Marina CMI [18]

Answer:

Option 1 - $\frac{At}{60}=g$

Step-by-step explanation:

Given : The goals against average (A) for a professional hockey goalie is determined using the formula $A=60(\frac{g}{t} )$ . In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.

To find : Which is an equivalent equation solved for g?

Solution :

Solve the formula in terms of g,

$A=60(\frac{g}{t})$

Multiply both side by t,

$At=60g$

Divide both side by 60,

$\frac{At}{60}=\frac{60g}{60}$

$\frac{At}{60}=g$

Therefore, option 1 is correct.

If the sum of the first 12 terms of a geometric series is 8190 and the common ratio is 2. Find the first term and the 20th term.

Reil [10]

The first term is 2 and the 20th term is 1048576 .

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

Here we have , If the sum of the first 12 terms of a geometric series is 8190 and the common ratio is 2. We need to Find the first term and the 20th term. Let's find out:

We know that Sum of a GP is :

⇒ $S_n = \frac{a(r^n-1)}{r-1}$

So ,Sum of first 12 terms is :

⇒ $S_1_2 = \frac{a(2^{12}-1)}{2-1}$

⇒ $8190=a(2^{12}-1)$

⇒ $\frac{8190}{4095}=a$

⇒ $a=2$

Now , nth term of a GP is

⇒ $a_n = ar^{n-1}$

So , 20th term is :

⇒ $a_2_0 = 2(2)^{20-1}$

⇒ $a_2_0 = (2)^{20}$

⇒ $a_2_0 = 1048576$

Therefore , the first term is 2 and the 20th term is 1048576 .
