Answer: The height of street would be 3.26 feet.
Step-by-step explanation:
Since we have given that
Angle of elevation = 71°
Distance traveled = 12 feet
Angle of elevation becomes 46°.
So, the height of the street lamp post would be
Hence, the height of street would be 3.26 feet.
Answer:
Just about 3.6
Step-by-step explanation:
a² + b² = c²
√(a² + b²) = c
√(2² + 3²) = c
√(4 + 9) = c
√(13) = c
3.605551275 = c
c ≈ 3.6
Answer:
7pi/9
Step-by-step explanation:
140 degrees * (pi/180 degrees) = 7pi/9
I believe it would be C) 7 1/q
Let the number of quarter be x and that of nickels be y
total number of coins will be:
x+y=85
thus
x=85-y.........i
total amount of money will be:
0.25x+0.05y=14.25....ii
substituting i in ii we get:
0.25(85-y)+0.05y=14.25
21.25-0.25y+0.05y=14.25
7=0.2y
y=7/0.02
y=35
thus
x=85-35=50
the number of quarters was 50 and that of nickels was 35
