All 4 stages span a total of 4 weeks or 28 days.

Egg - 2 days
Larva - 7 days
Pupa - 5 days
Adult - 14 days

This means that the larva exists for 7/28 = 25% of the time.

So, 25% of the randomly selected developing bees would be larva.

25% of 200 is 50. So, the answer is A.

Edit: The question is ambiguous. If by developing bees they exclude all the adult bees, then larva exist for 50% of the time and the answer would be 100.

the cost per year to lease a coffee shop in downtown austin varies directly with the size of the shop if a 1425 square foot shop

Ivahew [28]

Answer: $582,400

Step-by-step explanation:

Hi, to answer this question we have to write a proportion.

Proportion = square feet/ cost

Since a 1425 square feet shop cost 45600 to lease, the proportion is equal to: 1425/45600

For a 1820 square feet shop: 1820/x

Where x is the cost per year for leasing a 1820 square feet shop

1425ft/$456000= 1820ft/$x

1425/456000=1820/x

Solving for x:

x = 1820/(1425/456000)

x = $582,400

(4u^3+6u^2+7)+(6u^3-2u+7)<br> Simplify the sum'

Pie

Hi Nova

(4u³+6u²+7)+(6u³-2u+7)

= 4u³+6u²+7+6u³-2u+7

Combine like terms

( 4u³+6u³)+(6u²)+(-2u)+(7+7)

= 10u³+6u² -2u+14

There no like terms so you can not simplify the sum

I hope that's help and if you have questions please ask !
