To solve this problem, you will need to list several multiples of 3; these are the days that the whale show will be presented. Whale show: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 Now, list several multiples of 5; these are the days that the otter show will be offered. Otter show: 5, 10, 15, 20, 25, 30 Now, compare the two to find the LCM. Whale show: 3, 6, 9, 12, 15 , 18, 21, 24, 27, 30 Otter show: 5, 10, 15 , 20, 25, 30 The whale show and otter show will occur on the same day in 15 days.

answer: sine

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
