Step-by-step explanation:
Soln
From the above diagram
Height = h = 4cm
Let a&b = upward and downward lengths respectively.
That is:
a = 13cm
b = 16cm
recall that the formula used mathematically in solving/calculating the area of a trapezium is
Area = 1/2×(a+b)×h
Area = 1/2×(13+16)×4
Area = 1/2×(29)×4
Area = (29)×2
Area = 58cm²
Answer:
2 3/8
Step-by-step explanation:
You add 2 1/8 and 3 3/4 together= 5 7/8
Then subtract 5 7/8 from 8 1/4= 2 3/8
Answer:
2.5
Step-by-step explanation:
X= adult tickets
Y= Children tickets
You need two equations one is number of people
Second formula is the money
X+y= 429
1x+ .75Y= 372.50
You can use the substitution or elimination method
I will use substitution make X = 429-y using the 1st equation then put it in the 2nd
429-1y+.75y= 372.50
429 -.25y= 372.50
-429. -429
-.25y=. -56.5
Divide both side by -.25
y= 226
So 429-226= 203 for X
203 adult tickets and 226 children tickets
