First, we're going to add the species of angiosperms and gymnosperms together.
300,000 + 840 = 300,840

Then we're going to multiply 300,840 by 300,000.
300,840 x 300,000 = 9.0252E10

We're going to round the hundredth to the tenth now.
9.0252E10 = 9.0

This is how we know 9% is angiosperms and 91% is gymnosperms.

Your answer to this question is 91%.

Hope this helps!~

The location of the y value of R' after using the translation rule is -10

<h3>What will be the location of the y value of R' after using the translation rule? </h3>

The translation rule is given as:

(x + 4, y - 7)

The pre-image of R is located at (-17, -3)

Rewrite as

R = (-17, -3)

When the translation rule is applied, we have:

R' = (-17 + 4, -3 - 7)

Evaluate

R' = (-13, -10)

Remove the x coordinate

R'y = -10

Hence, the location of the y value of R' after using the translation rule is -10

Length of line RS is probably 20 because it’s not smaller than the line it’s parallel to but it’s not equal either so the answer has to be c unless there’s a d that’s between 10-20
