Answer:
x=13
Step-by-step explanation:
14x-2=180
+2 +2
14x=182
/14 /14
x=13
Let <em>a</em> be the first term in the sequence. If <em>r</em> is the ratio between consecutive terms, then the second term is <em>ar</em>, the third term is <em>ar </em>^2, the fourth is <em>ar</em> ^3, and so on, up to the <em>n</em>-th term <em>ar</em> ^(<em>n</em> - 1).
So the third, fourth, and fifth terms are such that
<em>ar</em> ^2 = 18
<em>ar</em> ^3 = 27
<em>ar</em> ^4 = 81/2
Solve for <em>a</em> and <em>r</em> :
(<em>ar</em> ^3) / (<em>ar</em> ^2) = 27/18 => <em>r</em> = 3/2
<em>ar</em> ^2 = <em>a</em> (3/2)^2 = 9/4 <em>a</em> = 18 => <em>a</em> = 8
Then the <em>n</em>-th term in the sequence is
<em>ar</em> ^(<em>n</em> - 1) = 9 (3/2)^(<em>n</em> - 1)
You can rewrite this by first rewriting 9 = 3^2, then
9 (3/2)^(<em>n</em> - 1) = 3^2 * 3^(<em>n</em> - 1) / 2^(<em>n</em> - 1) = 3^(<em>n</em> + 1)/2^(<em>n</em> - 1)
If the turkey is stuffed so time it will be cook is:
T = 22 lb ( 20 min/ lb) = 440 min = 7 hrs and 20 min
If the turkey is unstuffed so the timme it will be cook is:
T = 22 lb (15 min / lb) = 330 min = 5 hrs and 30 min
If she wants dinner at 4:00 pm and it should 30 min berfore
it is served
If the turket is stuffed so ii should be placed in the oven
at 8:10 am
If the turkey is un stuffed it should be placed at the oven
at 10:00 am

Step-by-step explanation:
Answer:
139.5
Step-by-step explanation:
A= (a + b) /2 *h
A = ( 13 + 18) /2 *9
A = 31 / 2 * 9
A = 15.5 * 9
A = 139.5
