120 miles = 3 hours
1mile = 3/120 = 1/40
200 miles = 1/40 times 200
= 5 hours
Answer:
Surface area = 90 cm²
Step-by-step explanation:
Given net of the rectangular prism shows the dimensions as,
Length = 5 cm
Width = 5 cm
Height = 2 cm
`Expression for the surface area of a rectangular prism = 2(lb + bh + hl)
Here, l = length
w = width
h = height
By substituting the values in the expression,
Surface area = 2(5×2 + 5×2 + 5×5)
= 2(10 + 10 + 25)
= 90 cm²
one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
