In a treasure chest, there are 20 gold pieces an 8 silver pieces. Which ratio accurately compares the number of gold pieces to the number of silver pieces?

5:2

Step-by-step explanation:

Ratio = Gold pieces : Silver pieces

We have 20 gold pieces

8 silver pieces

Ratio = 20 : 8

Dividing through by 4

= 5 : 2

Therefore, the correct ratio = 5:2

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

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.
