Answer:
12. 10.5 cm
13. 16 m
14. 8 m
15. 50.24 m
16. 200.96 m2
17. (16+4 =20 ÷2 =10 ·10·π =314 ÷2 =157) + (16·4 =64) =221 in2
18. (1.1 · 1.2 =1.32) + (1.2 · 4 =4.8 ÷2 =2.4) =3.72 in2
19. 10·5=50
20. c.(1/2 d)^2·π
Answer:
3/10
Step-by-step explanation: you multiply 3 and 1/10
Answer:
- Infinitely many solutions
Step-by-step explanation:
- 2x + x + 4 = 3x + 4
- 3x + 4 = 3x + 4
Both sides of the equation are exactly same.
It means regardless the value of x the equation is true.
The equation has infinitely many solutions.
What order do they have to be in least to greatest or greatest to least
Answer:
a) 5 people
b) Yes.
Step-by-step explanation:
The best way to solve this problem is to use the amount of work needed each week and divide it by the amount worked by each person (150/32). This will give you 4.6875. However, you cannot have 6/10 of a person, so you must round up to the next whole number, 5. There are 5 people needed to fulfill the amount of hours posted. For Part B, you will be decreasing the hours worked by each person from 32 to 30. Use the same method you did above and divide the total amount of work needed by the amount worked by each person (150/30) to get 5 on the dot. Your answer is Yes.
I hope this helps! Good luck!
