Answer:
FE = 30°
Step-by-step explanation:
arc FGC = arc FG + arc GB + arc BC
220° = 90° + arc GB + 70° . . substitute known values
60° = arc GB . . . . . . . . . . . . . subtract 160°
__
External angle A is half the difference of arcs EG and GB:
30° = (1/2)(arc FE +90° -60°) . . . substitute known values
60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify
30° = arc FE . . . . . . subtract 30°
_____
The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.
Answer:
$1.22 per pair
The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.
Step-by-step explanation:
1 dozen = 12
5 dozen = 12 * 5 = 60
Therefore, you have 60 pairs of gloves.
He purchased all 60 pairs of gloves for $73.20.
73.20/60 = $1.22
This is how much one pair of gloves cost.
Answer:
The slope is 9, and the y-intercept is –2
Step-by-step explanation:
y = 9x - 2
y = 9x + (-2)
This is in the form of y = mx + c ,where m is slope and c is y-intercept.
So, The slope is 9, and the y-intercept is –2.
In y-intercept, intercept means to cut. So,
y-intercept means where the equation cuts the y-axis. We know that in y-axis, the value of x is 0. So, we put x = 0 in the equation to find y-intercept.
y = 9x + (-2)
y = 9×0 - 2
y = -2
Hence, y-intercept is -2.
