1 2/8 OR 1 1/4
Step-by-step explanation:
4/8 + 2/8 + 4/8 =
6/8 + 4/8 =
10/8 =

Answer:
The correct option is C
Step-by-step explanation:
The organizers of a fair projected a 25 percent increase in attendance this year over that of last year
Let x = the attendance for last year
The projected attendance for this year would be last year's attendance + 25% of last year's attendance. This means
Projected attendance for this year
= x + 25/100 × x
= x + 0.25x = 1.25x
But attendance for this year actually decreased by 20 percent.
This means the actual attendance for this year would be
attendance for last year - 20% of attendance for last year. This means
Actual attendance for this year is
x - 20/100 × x
= x - 0.2x = 0.8x
percentage of the projected attendance that was the actual attendance would be
0.8x / 1.25x × 100 = 0.64 × 100
= 64%
The correct option is C
To find the equation for the line in slope-intercept form y= mx + b, perpendicular to the line shown and passing through (6, -6):
The slope of the blue line is the rise (change in y) divided by run (change in x)
Choosing two points on the line (0, -6) and (2,0)
Slope = (0 - (-6)) / (2 - 0) = 6 / 2 = 3
The slope of our perpendicular line will be the opposite inverse, so:
m = -1/3
We have the point (6, -6) so we can solve for b
y = mx + b
-6 = (-1/3)*6 + b
-6 = -2 + b
b = -4
We know that m= (-1/3) and b= -4, so:
y = (-1/3)x - 4
This is definitely the correct answer. None of the above answers describe the line that is perpendicular to the blue line and passes through (6, -6). Make sure you wrote the options down correctly.
Answer:
12-157.5 13-6ft
Step-by-step explanation:
the first one just look up 65% of 450 and minus the number you get by 450
the second one do the butterfly method
the heights on top and shadows on bottom
12x=72
x=6
