Alan is comparing the cost of a fresh lobster dinner at two different restaurants. The first
Pepsi [2]

Good evening ,

Answer:

The weight : 29 pound

Alan would pay for his dinner : $130

Step-by-step explanation:

Let x represent the weight of the lobster

the cost of the dinner at restaurant 1 is 4x + 14  

the cost of the dinner at restaurant 2 is 3x + 43

Now ,we have to solve the equation :  4x + 14 = 3x + 43

4x + 14 = 3x + 43

⇔ x = 43 - 14

⇔ x = 29

In this case Alan would pay the same amount for his dinner at any restaurant:

the price = 4×(29)+14 = 130

               = 3×(29)+43 = 130.

kobusy [5.1K]

Answer:

Option (b).

Step-by-step explanation:

It is given that Adrian built a structure out of 10 congruent cubes.  

Volume of each cube = 8 cubic centimetres.

We need to find the total volume of the structure.

V=10\times 8

V=80

Therefore, the total volume of the structure is 80 cubic centimetres.

Hence, option (b) is correct.

ANTONII [103]

Answer:

The mean growth annual rate over this period is 0.0036

Step-by-step explanation:

we know that

The mean growth annual rate is calculated as the sum of each year's growth rate divided by the number of years

\frac{5.5\%+1.1\%-3.5\%-1.1\%+1.8\%}{5}=0.36\%

Convert to decimal form

0.36\%=0.36/100=0.0036

therefore

The mean growth annual rate over this period is 0.0036
