Answer:
Total Cost, C=$(16S +56)
Step-by-step explanation:
Chris buys 8 more Ninja Turtles than Star Wars action figures.
Cost of each Ninja Turtle = $7
Cost of each Star Wars = $9
Let number of Star Wars bought = S
As per question statement, number of Ninja Turtles bought = S+8
Cost of 'S' number of Star Wars = Number of Star Wars bought 
cost of each Star Wars
Total cost of Star Wars bought = S 9 or $9S
Similarly, Cost of 'S+8' number of Ninja Turtles = Number of Ninja Turtles bought cost of each Ninja Turtles
Total cost of Ninja Turtles bought = (S+8) 7 or $(7S +56)
Total Cost of the purchase = Total cost of Star Wars Bought + Total cost of Ninja Turtles bought
Total Cost of the purchase, C = 9S + (7S +56)
Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.
The ratio is 7:5 so we would have:
7x + 5x = 180
Simplify:
12x = 180
Divide both sides by 12:
X = 15
So one angle is 7 x 15 = 105 degrees
The other angle is 5 x 15 = 75 degrees
An obtuse angle is an angle greater than 90 degrees.
The obtuse angle would be 105 degrees.
Answer:

Step-by-step explanation:
Answer:
603.40
Step-by-step explanation:
Minimum required score = Mean + ( Z-score * Standard deviation )
Given:
Mean = 500
Z score of 3 (0.03%) = 1.88
Standard deviation = 55
therefore
Minimum required score = 500 + (1.88)(55)
Minimum required score = 603.40
