Answer: 10
Step-by-step explanation: We can just count the number of vertices in the star and each vertex makes an angle. There are ten vertices in a star and thus ten angles.
First, find the decreased price by multiplying 100 by 8% and subtracting:
100 x 0.08 = 8
100-8 = 92 ( reduced price )
now multiply reduced price by 8% and add:
92 x 0.08 = 7.36
92 + 7.36 = $99.36
2,800-3,200
Explanation: multiply 35 and 40 by 80 since those are the variables
Rearrange the formula so that its in the form of y=mx+b
so it would be:
8y= -4x + 4
then divide by 8:
y= -4/8 x + 4/8:
Simplify:
y= -1/2x + 1/2
the slope is -1/2
Answer:
78.26
Step-by-step explanation:
130+50= 180
.45-.15+2=2.3
180/2.3=78.26
