7100000 grams. 1 kilogram is equal to 1000 grams
She is incorrect
the GCF of 2, 4 and 8 is 2 (not 8 has she has written)
the GCF of x2, xy and xy4 is x not x2y4
Correct GCF of the 3 terms is 2x
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
<h3>Equation for
speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent Karen speed and b represent Melinda speed, hence:
a = b + 10
a - b = 10 (1)
Also:
a = d₁ / 1
d₁ = a
b = d₂/ 1 hour
d₂ = b
Since they are 108 miles apart, using Pythagoras:
108² = d₁² + d₂²
a² + b² = 11664
(b + 10)² + b² = 11664
b = 71.2 mph, a = 81.2 mph
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

a line is 180º total
180-70-30=80
Answer:
see explanation
Step-by-step explanation:
since the triangles are congruent, then corresponding angles are congruent.
∠ B = ∠ F
∠ FCE ≅ ∠ BDA
∠ EFC ≅ ∠ ABD
∠ FEC ≅ ∠ BAD
note that the order of letters in Δ ABD follows the same order as those in Δ BDA
