Ok so 4*5=20
so the area is 20meters
now lets convert 200cm to m
= 200/100=2m
now 20m/2=10
so therefore, the gardener would need 10 bags of grass seeds
hope this helped :)
Answer:
35%
Step-by-step explanation:
See attached for visual
- 160= 8*20
- 8 = 1/20 = 5% of 160
- 56= 8*7
- 7*5% = 35%
56 is 35% of 160
Answer:
x = 4 and y = - 5
Step-by-step explanation:
note that the product of a complex number and it's conjugate is real
That is
(a + bi)(a - bi) where a, b are real
= a² - abi + abi - b²i²
= a² + b² ← a real number
For (4 + 5i)(x + yi) to be real
we require (x + yi) to be the conjugate of 4 + 5i , that is 4 - 5i
(4 + 5i)(4 - 5i) ⇒ x = 4 and y = - 5
