Ratios Help easyyy plzz help me !!!!!
schepotkina [342]

The first one states that there are 6 cups of orange juice for every _ cups of punch

There are 6 cups of orange juice and 4 cups of cranberry in 10 cups of juice because 6 c orange + 4 c cranberry = 10 cups total punch

So for 6 cups of orange juice there would be 10 cups of punch.

The 3rd one states that the ratio of cranberry juice to punch is _:_

Punch is cranberry and orange combined- at the ratio of 4:6

So for 4 cups of cranberry, there would be 10 cups punch (4 c cranberry + 6 c orange = 10 c punch)

So the ratio would be 4:10, it can be simplified like fractions as 2:5

I don't know is you have to but if you do, don't forget to simplify the ratios.

Good luck!

Given that Ray B A bisects ∠DBC, which statement must be true? m∠ABD = m∠ABC AB ≅ BC B is the midpoint of DC. m∠DBC = 90°
nadya68 [22]

Answer:

A.m\angle ABD=m\angle ABC

Step-by-step explanation:

We are given that a  ray BA bisects angle DBC.

We have to find true statement .

Angle bisector property:When a ray bisect any angle then the angles  made by bisection of angle are equal.

When ray BA bisects angle DBC

Then, m\angle ABD=m\angle ABC

By angle bisector property.

Therefore, option A is true.

Answer:A.m\angle ABD=m\angle ABC
