There are 7 roses in a vase of 16 flowers. The rest are daisies.
Greeley [361]

Answer:

(a) 7:9 or 7 to 9 or \frac{7}{9}

(b) 9:16 or 9 to 16 or \frac{9}{16}

Step-by-step explanation:

The first thing you need to figure out is how many daisies are in the vase. There are 9. So the answer to question a is 7 roses to 9 daisies. The answer to question b is 9 daisies to 26 total flowers in the vase.

I wrote #:# or # to # or \frac{#}{#}#/# because these are all of the ways you can write a ration. I wasn't sure which one you needed.

Hope it helps! :)

V = lhr

V ÷ lh = lhr ÷ lh

Can someone help me with the top 1-3. Using similar figures subject
katen-ka-za [31]
Answer: <M corresponds to <J
               <L corresponds to <O
               JL corresponds to MO 

To find the corresponding angles:
1. Look at the figures. 
<M is to <J, <N is to <K, and <O is to <L.

2. Look at the similarity statement. 
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.

Apply these two methods to find the corresponding sides.

If B is the midpoint of line AC, AC = CD, AB = 3x+4, AC=11x-17, and CE = 49, find DE. (Show work)
larisa [96]

Answer:

2(3x+4) = 11x-17

6x+8 = 11x-17

25=-5x

x=-5

11x-17

55-17

38

AC = 38

CD = 38

49-38 = 11

DE = 11

Let me know if this helps!
