Answer: C = 43.96
Step-by-step explanation: The equation to calculate the circumference of a circle is
C = 2 π r
Using the information from the diagram,
C = 2 x 3.14 x 7
Now, solve the equation,
C = 43.96
Answer:
C.
Step-by-step explanation:
Part À: x=0 because anything to the zeroth power is one, so the only answer would be 0.
Part B: x=1 OR 0 because we know 5^0 is one, and one to the first power is just one too. One to the zeroth power is also one.
Answer:
x = 15
Step-by-step explanation:
Because PQ is parallel to JL,
Substituting, we have
5(x-6) = 3x
5x - 30 = 3x
2x = 30
x = 15
Answer:
see below
Step-by-step explanation:
Angle ACE = DCE since they are vertical angles
Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles
Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles
When all three angles are equal, the triangles are similar.
We can use ratios to find DE
DE CE
------- = ----------
AB AC
DE 8
------- = ----------
12 10
Using cross products
10 DE = 8*12
10 DE = 96
Divide by 10
DE = 9.6
