Can anyone help with these? Don't understand how to do it

Mathematics
1 answer:
amid [387]3 years ago
6 0

Answer:

1) EA= 50 (because is a vertical angle with CB and vertical angles are congruent)

3) DEB = 210 ( to find AB subtract EA from 180, so 180-50 = 130. Then add together arcs DE, EA and AB to find the total measurement of DEB)

5) AB = 130 (I explain how to find it in question #3)

6) CDA = 180 ( To find CDA just add the measurements of CD, DE and EA together)

(sorry don't know the rest, hope this helps)

When Elena makes bird food, she usually mixes 9 cups of seeds with 6 tablespoons of maple syrup. However, today she is short on
svetlana [45]

Answer:3 cups of seeds and 2 tablespoons of maple syrup

-OR-

6 cups of seeds and 4 tablespoons of maple syrup

Step-by-step explanation:

As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"

The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"

Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.
