Answer:
Total cost= $141.75
Step-by-step explanation:
Giving the following information:
Bernie's Bargains 6 DVDs for $56.70
Greg's Giveaways 10 DVDs for $99.70
Stan's Steals 8 DVDs for $79.68
<u>First, we need to determine the unitary price of each and choose the lowest one:</u>
Bernie= 56.7/6= $9.45
Greg= 99.7/10= $9.7
Stan= 79.68/8= $9.96
The lowest price is $9.45.
<u>Now, the total cost of 15 DVDs:</u>
Total cost= 9.45*15
Total cost= $141.75
Answer: nevermind makes sense now
1 and 1/6
Answer:

Step-by-step explanation:
is in the third quadrant
To find the reference angle subtract π from it, that is
reference angle =
- π = 
Answer: a = 1 b = 7
Step-by-step explanation:
x^2(y^3)^4/x.y^5 = x^a.y^b
x^2(y^12) = x^a.y^b
(x^2).(y^12)/x^y^5 = x.y^7
x.y^7= x^a . y^b -> <u>x^1.y^7</u>
Substitute the given number into the equation
Sum = 180(15-2)
Solve brackets
180(13)
Which is equal to 2340
So, the sum of interior angles is 2340 degrees
