Do you understand?
1. how many zeros will there be in the
product of 39 x 1,000? how many
zeros will there be in the product of
50 x 1,000?
2. explain how to find the product of
90 x 104 what's the answer

1) There is three zeros for 39×1000.

There is four zeros for 50×1000.

2) 9,360

Step-by-step explanation:

1,000×39=39,000 which has three zeros

1,000×50=50,000 which has four zeros

104×90=9,360

all it means is function 3

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.
