Answer:
The cost of Daffodil bulb is $ 3.5 And
The cost of Tulip bulbs is $ 5
Step-by-step explanation:
Given as :
The total number of tulip bulbs (T) for front yard = 30
The total number of tulip bulbs for back yard = 16
The total number of daffodil bulbs (D) for front yard = 32
The total number of daffodil bulbs for back yard = 40
The amount spend on front yard = $262.00
The amount spend on back yard = $220.00
so, according to question
30 T + 32 D = $ 262
16 T + 40 D = $ 220
Or, 480 T + 512 D = 4192 ...... 1
And 480 T + 1200 D = 6600 ....... 2
Solving eq 1 and 2
Or, ( 480 T + 1200 D ) - ( 480 T + 512 D ) = 6600 - 4192
Or, 688 D = 2408
∴ D = = $ 3.5
Put The value of D in above eq
480 T + 1200 × (3.5) = 6600
Or, 480 T = 6600 - 4200 = 2400
∴ T = = $ 5
Hence The cost of Daffodil bulb is $ 3.5 And
The cost of Tulip bulbs is $ 5 Answer
Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) =
OP.Cosθ = 1×Cosθ =
Cosθ =
θ = ,
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = ,
where n = integer
Common value of θ will be, θ =
Option B will be the answer.
