The answer is 56%
You first divide 28 by 50=.56, then since it's a decimal, you move the decimal twice to the right to make a percentage=56%
Answer:

Step-by-step explanation:
3 gallons of blue paint and 5 gallons of yellow paint and this answer is a fraction so
is the answer.
Answer:
Multiply both sides by -2 and reverse the inequality symbol
Step-by-step explanation:
since it is division you want to make it multiplication so that you can get the answer easier
-1/2w<12
it cancels out the -1/2 than just multiply 12 and -2 you get -24
w > -24
Answer:
x5=y
Step-by-step explanation:
Let's say 3y=15
3 x 5 = 15, so y=5.
Answer:
Given A triangle ABC in which
∠C =90°,∠A=20° and CD ⊥ AB.
In Δ ABC
⇒∠A + ∠B +∠C=180° [ Angle sum property of triangle]
⇒20° + ∠B + 90°=180°
⇒∠B+110° =180°
∠B =180° -110°
∠B = 70°
In Δ B DC
∠BDC =90°,∠B =70°,∠BC D=?
∠BDC +,∠B+∠BC D=180°[ angle sum property of triangle]
90° + 70°+∠BC D =180°
∠BC D=180°- 160°
∠BC D = 20°
In Δ AC D
∠A=20°, ∠ADC=90°,∠AC D=?
∠A + ∠ADC +∠AC D=180° [angle sum property of triangle]
20°+90°+∠AC D=180°
110° +∠AC D=180°
∠AC D=180°-110°
∠AC D=70°
So solution are, ∠AC D=70°,∠ BC D=20°,∠DB C=70°
