Let's solve for r.
E=IR
Step 1: Flip the equation.
IR=E
Step 2: Divide both sides by i.
IR/I=E/I
R=E/I
Answer:
R=E/I
d =st
distance = speed * time
10 = 4.5 * t
divide each side by 4.5
10/4.5 = t
100/45 = t (can't have a decimal in a fraction so I multiply by 10/10)
divide top and bottom by 5
20/9
2 and 2/9 hours
to get minutes multiply 2/9 by 60
2/9 * 60
120/9
13 3/9
13 1/3 minutes
2 hours 13 1/3 minutes
to the nearest minutes
2 hours 13 minutes
Answer:
congruent angles are angles that have the same degree so for example a 45° angle and another 45° angle are congruent
supplementary angles are two angles that add up to 180° or in other words a straight line so an angle that is 100° along with an angle that is 80° would be supplementary
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
I think a partial variation
