Answer:
5.5, 7, 8.5
Step-by-step explanation:
Find the mean of 4 and 10, that is
= 
= 7
Now repeat with 4 and 7 and 7 and 10
= 
= 5.5
= 
= 8.5
Hence
4, 5.5, 7, 8.5, 10 ← is an arithmetic sequence with d = 1.5
Answer:
4. No
5. No
6. No
7. No
8. No
9a. 2 : 3 = 8 : 12 Extremes: 2, 12. Means: 3, 8
9b. 90 : 36 = 135 : 54 Extremes: 90, 54. Means: 36, 135
Step-by-step explanation:
4. 12 : 25 and 6 : 13 are NOT equal. NO.
5. 64 : 120 = 8 : 15 and 60 : 100 = 3 : 5. NOT equal. NO
6. 37 : 115 and 296 : 966 = 148 : 483. NOT equal. NO
7. 300 : 200 = 3 : 2 and 6 : 5 are NOT equal. NO.
8. 8 : 10 = 4 : 5 and 11 : 14 are NOT equal. NO.
9a. 2 : 3 = 8 : 12 Extremes: 2, 12. Means: 3, 8
9b. 90 : 36 = 135 : 54 Extremes: 90, 54. Means: 36, 1135
Answer:
A:
The perimeter of the parking lot is 302 yards.
The area of the parking lot is 5,544 yards squared.
B: Perimeter
C: Area
Step-by-step explanation:
A:
To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.
2(63) + 2 (88) = 302
To find the area, we multiply the length by the width. 63 × 88 = 5,544.
B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.
C: We would be paving the entire area of the parking lot.

Answer:
3.14
Step-by-step explanation:
Answer:
x = 19
Step-by-step explanation:
The two angles with measures are supplementary.
6x + 9 + 4x - 19 = 180
10x - 10 = 180
10x = 190
x = 19
