We have a total of 178 6th and 7th graders. And we are informed that there are 12 more 6th graders the 7th graders. Let x = the number of 7th graders
x + (x + 12) = 178
Subtract 12 from both sides
x + x = 166
Add like terms
2x = 166
x = 83
So, there are 83 7th graders. And add 12 to find the number of 6th graders.
12 + 83 = 95
The formula is y=mx+b.
m-slope
b-the point where the line crosses the y-axis.
6.051 ×
=
605,100
So, your answer would have to be
605,100
Since the exponent of the scientific notation is a positive five ((5)), move the decimal point to the right
Sin(angle) = opposite/hypotenuse
sin(H) = GF/HF
sin(H) = 5/13
arcsin(sin(H)) = arcsin(5/13)
H = 22.61986 ... which is approximate
H = 23 degrees ... round to the nearest whole number
Answer is choice A
