28! hope this helps, you just plug in 4 for x, and then multiply by two.
Answer:
20 is the longer piece, and 9 is the shorter piece
Step-by-step explanation:
9*2=18
18+2=20
20+9
2.75 x + 3.55 y ≤ 2,479
x + y = 820
( x - number of units produced during the regular hours, y - number of units produced in overtime )
y = 820 - x
2.75 x + 3.55 · ( 820 - x ) ≤ 2.749
2.75 x + 2,911 - 3.55 x ≤ 2,749
- 0.8 x ≤ 2,749 - 2,911
- 0.8 x ≤ - 432 / · ( - 1 )
x ≥ 432 : 0.8
x ≥ 540
Answer:
The smallest number of units that must be assembled during the regular hours is 540.
Answer:
<u>161.5 cm²</u>
Step-by-step explanation:
Finding the remaining area :
- Area (rectangle) - Area (2 equal semicircles)
- Area (rectangle) - Area (circle) [Because 2 equal semicircles form a circle of the same radius]
- 24 × 10 - 3.14 x 25
- 240 - 78.5
- <u>161.5 cm²</u>
