Answer:
The answer to your question is:
1st Diego
2nd Diego and Elena ( both 15 days)
Step-by-step explanation:
Data
Lin 54 pages 270-page book 3 days
Diego 100 pages 320 page 4 days
Elena 160 pages 480 page 5 days
Process
Lin
54 pages ------------------- 3 days
270 page ----------------- x
x = (270 x 3) / 54
x = 15 days
Diego
100 pages ----------------- 4 days
320 -------------------- x
x = (320 x 4) / 100
x = 12.8 days
Elena
160 pages ------------------- 5 days
480 pages -------------------- x
x = (480 x 5) / 160
x = 15 days
Answer:
The allowable lengths of pipe is from 21.78 inch to 22.22 inch.
Step-by-step explanation:
The length of the each pipe in the shipment = 22 inch
The variation in the length of pipes = 1%
⇒The allowable length of pipe in the inspection = 22 inch ± 1%
Now, 1% of 22 = 
So, 22 inch + 1% = 22 inch + 0.22 = 22.22 inch
and 22 inch - 1% = 22 inch - 0.22 = 21.78 inch
⇒ 22 inch ± 1% = 22.22 inch and 21.78 inch
Hence, the allowable lengths of pipe is from 21.78 inch to 22.22 inch.
Answer:
10
Step-by-step explanation:
substitute the given values into the expression
2(x + z) - y
= 2(6 + 3) - 8
= 2(9) - 8
= 18 - 8
= 10
- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2
