Answer:

30

Step-by-step explanation:

Find the trapezoid area.

A=1/2h(b1+b2)

A=1/2(12)(6+15)

A=1/2(12)(21)

A=6(21)

A=126

Find the square

A=s²

A=15²

a=225

Add them.

126+225=351

Divide

351÷12=29.25

Round to 30 because 29 not enough.

The weather satellite shows that hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilome
jenyasd209 [6]

Answer:

1. 3 days.  

Step-by-step explanation:              

We have been given that the hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilometers per hour.

First of all we will find the number of hours it will take for George to reach Puerto Rico. We can find number of hours taken by hurricane George to reach Puerto Rico by dividing 1728 by 24.

\text{Time}=\frac{\text{ Distance}}{\text{ Speed}}

\text{Time taken by hurricane George to reach Puerto Rico}=\frac{1728}{24}

\text{Time taken by hurricane George to reach Puerto Rico}=72

We can see that George will reach Puerto Rico in 72 hours. Let us convert hours to days by dividing 72 by 24 (number of hours in a day).

\text{Days taken by hurricane George to reach Puerto Rico}=\frac{72}{24}=3

Therefore, the hurricane George will reach to Puerto Rico in 3 days, if the hurricane stays on its present course. Our first option is the correct choice.
