Answer:
1/5
Step-by-step explanation:
5/5 - 4/5 = 1/5
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of GF is 254 units.
<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
Since a centroid of a triangle divides the median into a ratio of 2:1. Therefore, the ratio of AG: DG is,
AG / DG = 2/1
(19x+14)/(9x+20) = 2/1
19x + 14 = 18x + 40
19x - 18x = 40 - 14
x = 26
Assuming the triangle is an equilateral triangle, therefore, the length of GF will be,
GF = DG = 9x+20
GF = DG = 9(26) + 20
GF = 254 units
Hence, the length of GF is 254 units.

Answer: $76 will be the total for one and a half ours for a repair.
Step-by-step explanation:
28 + 16hh
hh = half hour
1 and a half hours = 3 half hours
28 + 16(3)
28 + 48 = 76
Answer:
We can expect $1.7 off
Step-by-step explanation:
We are given 10 fortune cookies out of which
$1 off = 7 cookies
$2 off = 2 cookies
$6 off = 1 cookie
Probability
A = drawing $1 off cookies P(A) = 7/10
B= drawing $2 off cookies P(B) = 2/10
C= drawing $6 off cookie P(B) = 1/10
Expectation = 1*7/10 + 2*2/10+ 6*1/10
= 7/10 + 4/10 + 6/10
= 17/10 = $1.7 off
