Option C:
We can find the value of PR using law of cosines.
Solution:
Given data:
∠Q = 18°, r = 9.5, p = 6.0
To find which length could be find in the triangle:
Law of cosines:
Substitute a = q, b = r, c = p and A = Q
If we substitute the values given, we can find q.
q = PR
Hence we can find the value of PR using law of cosines.
Option C is the correct answer.
Solve for w: by simplifying both sides of the equation, then isolating the variable.
w=-217
Work: 1. Subtract 13 from both sides (w/7 = -18 - 13), 2.Simplify -18-13 to -31 (w/7=-31), 3.Multiply both sides by 7 (w = -31 * 7), 4. Simplify 31*7 to 217 (w=-217)
Since it’s $80 for 5 tickets, we divide 80/5 to get the price of one ticket, giving us
C = 16*n.
Plug in 5 for n and you’ll get 80
<span>Juanita
is watering her lawn using the water that is stored by rainwater.
=> the water in the tank drops 1/3 inch in every 10 minutes she waters.
=> The tanks water level is 4 feet.
Question : Number of days can Juanita waters is she waters 15 minutes per day.
=> 4 feet is the total amount of water = 1 ft = 12 inches
=> 48 inches in total
=> 1/3 inch is used every 10 minutes = 0.33 inches
=> she waters 15 minutes per day = 0.495 inches in every 15 minutes
Solution
=> 48 inches / 0.495 inches per day
=> 96.97
So Juanita can use all the water in water tank for approximately 97 days.</span>
Answer:
18564
Step-by-step explanation:
In the problem Given, we just need to see t any 6, the order of selection does not matter, hence, this is a combination problem :
Using the combination relation :
nCr = 18C6
Recall ;
nCr = n! / (n-r)!r!
18C6 = 18! / (18-6)!6!
18C6 = 18! / 12!6! = (18*17*16*15*14*13) / (6*5*4*3*2*1)
18C6 = 13366080 / 6!
18C6 = 18564
