2 / 15 = 30 / x.....2 inches to 15 miles = 30 inches to x miles

could also be :

15 /2 = x/30...15 miles to 2 inches = x miles to 30 inches

either way, u will get the same answer

Hacksaw’s Boats of St. Lucia takes tourists on a daily whale/dolphinwatch cruise. Their brochure claims an 80% chance of siting
Fittoniya [83]

Answer:

The probability you see a dolphin or a whale on both days is 0.64

Step-by-step explanation:

Consider the provided information.

It is given that the brochure claims an 80% chance of siting a dolphin or a whale.

The provided claims can be written as: 80% or 0.80

Let say first day you see a dolphin or a whale and same happen on the next day.

Thus, the probability is:

0.80 × 0.80 = 0.64

Probability of see them on both days is 0.64

Hence, the probability you see a dolphin or a whale on both days is 0.64

Help I don’t get it..
yan [13]

Answer:

Step-by-step explanation:

the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.

we also know that the area of one side of the cube is  3 \frac{1}{4}

so multiply that  

W x L = area

 3 \frac{1}{4} * 3 \frac{1}{4} = area

10 \frac{9}{16}  = area

10.5625 = area

those two answer above are the same .. just one is in fractions and one is in decimals

there are 6 sides on a cube, so multiply the above answer by 6

6* answer = 63.375

63 \frac{3}{8}  ( this is your answer)

both of those are also identical , but look different for the reasons I mentioned above

use which ever from seems better to you.  :)
