There are 1500 bees in a colony. Each month, the number of bees decreases by 12%. There are 800 flowering plants in a garden. Ea

Shkiper50 [21]

Part A:Bees: f ( t ) = 1,500 * 0.88^tFlowering plants: g ( t ) = 800 - 25 tPart B :f ( 6 ) = 1,500 * 0.88^6 = 696.6 ≈ 697
g ( 6 ) = 800 - 25 * 6 = 800 - 150 = 650Part C :f ( 7 ) = 1,500 * 0.88^7 = 613g ( 7 ) = 800 - 7 * 25 = 625f ( 7 ) ≈ g ( 7 )After approximately 7 months.

Find the sum of all 11 terms of an AP whose middlemost terms is 30?

Bond [772]

Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.

Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.

Aldo’s coffee shop makes a blend that is a mixture of two types of coffee.Type A coffee costs 5.6 per pound. Type B costs 4.05 p

Pie

Answer: 93

Step-by-step explanation: $\\$ Since 160 cups of blend are sold , this means

$\\$ A + B = 160

$\\$ Since Type A is sold for 5.6 per pound , that means the total number of A sold = 5.6A

$\\$ Also , Type B is sold for 4.05 per pound , the total number of B sold = 4.05B

$\\$ And it was given that the total cost of blend = 751.85 , then

5.6A + 4.05B = 751.85

$\\$ A + B = 160 ............................. eqn 1

$\\$ 5.6A + 4.05B = 751.85 ..................... eqn II

$\\$ From eqn I , A = 160 - B ................ eqn III

$\\$ Substitute A = 160 - B into equation II , then we have:

$\\$ 5.6(160 - B) + 4.05B = 751.85

$\\$ Expanding , we have

$\\$ 896 - 5.6B + 4.05B = 751.85

$\\$ 896 - 1.55B = 751.85

$\\$ collecting the like terms

$\\$ 1.55B = 896 - 751.85

$\\$ 1.55B = 144.15

$\\$ Therefore B = 144.15/1.55

$\\$ B = 93
