i really thinks its 6.9*10 to the power of 2
Answer:
Step-by-step explanation:
P(x)=S(x)-C(x)
0.8=9-C(x)
C(x)=9 -0.08
C(x)=8.92
Answer:
150 feet
Step-by-step explanation:
There are 10 marks between the 1st and 11th mark.
Since each mark represents 5 yards, 10 * 5 = 50 yards
Since 1 yard = 3 feet
50 yards = 50 * 3 = 150 feet
Answer:
42°, 101°
Step-by-step explanation:
These answers come from the angle subtraction postulate.
To get the midsegment, namely HN, well, we need H and N
hmm so.... notice the picture you have there, is just an "isosceles trapezoid", namely, it has two equal sides, the left and right one, namely JL and KM
the midpoint of JL is H and the midpoint of KM is N
thus
