Answer:
Mean, since it represents the most frequent number
Answer:
x = 20°
Step-by-step explanation:
Since BD = CD then Δ BCD is isosceles and its base angles are congruent, so
∠ CBD = ∠ BCD = 80° , then
∠ BDC = 180° - (80 + 80)° = 180° - 160° = 20°
∠ ADC = 180° - (80 + 60)° ← sum of angles in triangle
∠ ADC = 180° - 140° = 40° , then
∠ BDC + x = 40°
20° + x = 40° ( subtract 20° from both sides )
x = 20°
The unit ratio is defined as the total cost divided by the number of oz.
So, the large popcorn has a unit cost of
meaning that 1oz of pop corn costs 7 cents.
Similarly, the small popcorn has a unit cost of
meaning that 1oz of pop corn costs 8 cents.
So, the large popcorn has a lower unit rate.
Set the two values equal to each other with 18x-2=12x+2 and then plug it in to the equation and solve
Since we know the polygons are similar, the side length ratio of each side must be equal.
13/5 = x/10
Multiply both sides by 10
x = 26
That's your answer. Have a nice day! :)
