Step-by-step explanation:
These are similar triangle
We can use ratios to solve
12 12+4
------ = ----------
9 9+DC
Using cross products
12( 9+DC) = 9*(12+4)
12 (9+DC) = 9*16
Divide each side by 12
12/12 (9+DC) = 9*16/12
9+DC = 12
Subtract 9 from each side
9+DC-9 =12-9
DC =3
<u><em>Answer:</em></u>
Savanna had 6 more iris blooms this year
<u><em>Explanation:</em></u>
<u>We are given that:</u>
Last year, she had 40 iris blooms
This year, she has 15% more iris blooms than last year
<u>This means that:</u>
This year she has = (40 + 15% of 40) iris blooms
This year she has = 40 + 0.15(40)
This year she has = 40 + 6 = 46 iris blooms
<u>Now, we get the increase in the number of blooms:</u>
Increase = amount she has this year - amount she had last year
Increase = 46 - 40 = 6 iris blooms
Hope this helps :)
