<h3>
Answer: C) 25%</h3>
Explanation:
There are 7 blue out of 5+7+6+10 = 28 chips total.
7/28 = 1/4 = 25/100 = 25% is the probability of pulling out a blue chip.

Answer:
not a function
Step-by-step explanation:
When a left-side point originates more than 1 arrow, the relation is not a function. There are two such points here, so this relation is not a function.
Answer:
0.324m^2 ; 18 ft
Step-by-step explanation:
Given the triangle :
Base (b) of triangle = 54cm
Height (h) of triangle = 1.2m
Area(A) of a triangle is given by:
0.5 * base * height
Base = 54cm = 54/100 = 0.54 m
Therefore,
A = 0.5 * 0.54m * 1.2m
A = 0.324m^2
2.) Average of the two bases in the trapezoid :
From the trapezium Given :
Base 1 = 15 feets
Base 2 = 7 yards
1 yard = 3 Feets
Therefore, base 2 in Feets = 7 * 3 = 21 Feets
Average of the two bases :
(21 Feets + 15 Feets) / 2
= 36 Feets / 2
= 18 Feets
N+d=21
5n+10d=170
so
multiply first equation by -5 and add to other one
-5n-5d=-105
<u>5n+10d=170 +</u>
0n+5d=65
5d=65
divide both sides by 5
d=13
sub back
n+d=21
n+13=21
minus 13 both sides
n=8

Answer: an adult ticket cost $8 and a student ticket cost $4
Step-by-step explanation:
Let x represent the cost of one student ticket.
Let y represent the cost of one adult ticket.
A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. It means that
132x + 64y = 1040 - - - - - - - - - -1
An adult ticket costs twice as much as a student ticket. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
132x + 64 × 2x = 1040
132x + 128x = 1040
260x = 1040
x = 1040/260 = 4
y = 2x = 2 × 4
y = 8
