If the height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°, then the length of the base of the <span>pyramid is
2(71) tan 42 = 127.86
The closes answer is 127 feet</span>
The ratio of growth is 26.1/25.9 = 261/259
in x years the median age = 25.9 * (261/259)^x
in 2019 (after 10 years) = 25.9 * (261/259)^10 = 27.97
Here's our data:
15 questions total
Total number of points: 100
Spelling questions are worth 5 and represented by x
Vocab questions are worth 10 and represented by y
Therefore:
x+y=15
5x + 10y= 100
So:
x+y=15
x= 15-y
5x +10y =100
5(15 -y) +10y =100
75 -5y +10y =100
75 +5y = 100
5y=25
y=5
x +y=15
x+5=15
x=10
There are 10 spelling questions and 5 vocab questions
