Answer:
p = 2
Step-by-step explanation:
Step 1: Write equation
-5 + -2p = -9
Step 2: Solve for <em>p</em>
<u>Simplify:</u> -5 - 2p = -9
<u>Add 5 to both sides:</u> -2p = -4
<u>Divide both sides by -2:</u> p = 2
Step 3: Check
<em>Plug in p to verify it's a solution.</em>
-5 - 2(2) = -9
-5 - 4 = -9
-9 = -9
Just add up how much Luna practiced which is 20+30+20 to get 70 and then add another 30 to get 100. So Elsa practiced for 100 minutes or 1hour 40 minutes.
The area of any circle is (pi) · (radius)² .
The radius is 1/2 of the diameter.
For your circle, the radius is 1/2 of 14 inches = 7 inches,
and the area is
(pi) · (7 inches)²
= (pi) · (49 square inches)
= 153.9 square inches (rounded)
Answer:
I believe this is how you do it
Step-by-step explanation:
csc∅tan∅
(1/sin∅)(sin∅/cos∅)
(sin∅)/(sin∅cos∅)
1/(cos∅)
