The answer is D. (2.9,-22.8)
Answer: 240
Step-by-step explanation:
As per given ,
Number of choices for Receiver = 5
Number of choices for CD Player= 4
Number of choices for Speakers = 3
Number of choices for Cassette Deck =4
If a switch board display in the store allows a customer to hook together any selection of components , then by product rule
The number of ways one component of each type be selected = (Number of choices for Receiver) x (Number of choices for CD Player) x (Number of choices for Speakers )x (Number of choices for Cassette Deck)
= 5 x 4 x 3 x 4 = 240
Hence, the answer is 240.
Answer:
Positive.
Step-by-step explanation:
Any number greater than 0 is positive. Based on the question, we cannot assume that it is an integer or rational, but since x > 0, we can say with absolute certainty that the number is positive.
Answer:
745.44 mm² (nearest hundredth)
Step-by-step explanation:
Section the shape into a semicircle, a rectangle and a triangle by drawing a line vertically through the point, and a vertical line upwards from the corner of the 12.5 mm and 32.5 mm corner.
area of semicircle = (1/2) 
r² = 78.125 mm²
area of the rectangle = 12.5 x 25 = 312.5 mm²
area of triangle = 1/2 x (55 - 25) x 12.5 = 187.5 mm²
total area = 312.5 + 78.125 + 187.5 = 745.44 mm² (nearest hundredth)
