Mathematics
1 answer:
serg [7]3 years ago
3 0

Answer:

14. 1 inch = 96 miles (12 × 8)

1/2 inch = 48 miles (96 ÷ 2)

96 + 48 = 144 miles

3 3/4 = 3.75

144 ÷ 3.75 = 38.4

A. 38.4 mph

15. Adding a negative number is the same as just subtracting.

D. 35(2) - 1/2(15)

20. - = withdrew because you are subtracting

+ = deposited because you are adding

D. Peter withdrew $47.27 and deposited $598, increasing his bank account by $550.73

21. Yana: 7 - 3 + 6 - 1 + 8 - 2 = 15

15 ÷ 6 = 2.5 average

Amber: 1 + 5 - 2 + 4 - 2 + 6 = 12

12 ÷ 6 = 2 average

2.5 - 2 = 0.5

A. Yana's average number of points is 0.5 point greater than Amber's

Determine the length of the longest metal rod which could be stored in a rectangle box 20 cm by 50 cm by 30 cm.
navik [9.2K]

Answer:

61.64 cm

Step-by-step explanation:

The longest metal rod which could be stored in a rectangular box will be equal to its diagonal:

\therefore \: length \: of \:metal \: rod  \\  =  \sqrt{ {l}^{2} +  {b}^{2}   +  {h}^{2} }  \\  =  \sqrt{ {20}^{2} +  {50}^{2}  +  {30}^{2}  }  \\  =  \sqrt{400 + 2500 + 900}  \\  =  \sqrt{3800}  \\  = 61.64414 \\  = 61.64 \: cm
