Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
Answer:
Min 80, Q1 82, Med. 85.5, Q3 93, Max 100.
90%.
Step-by-step explanation:
Percentage at least 82 = 100 *(100 - 82) / (100-80)
= 90%.
Answer:
A.
Step-by-step explanation:
Distributive property means (in this case) to multiply what's inside the () by what's outside the (). Therefore, I believe A is the only one that makes sense.

The area base when the trapezoid-based right prism has a volume of, 6cm,5 cm, and 1 cm should be 6.
Calculation of the area
Here we assume
a = 6
b = 5
c = 1
Now we know that
<h3>What is the area of the trapezoid-based right prism?</h3>
= 6
Hence, The area base when the trapezoid-based right prism has a volume of, 6cm,5 cm, and 1 cm should be 6.

Answer:
Step-by-step explanation:
2+9-18/3x2-10
Lets follow order of ops.
/, x, +, -
Divide first.
2 + 9 - (18/3) x 2 - 10
2+9-6x2-10
Now we multiply.
2+9-(6x2)-10
2+9-12-10
Add.
11-22
Now subtract.
11-22=-11
