The area of a shape is the amount of space it can occupy.
<em>The surface area of the larger prism is 4 times the surface area of the smaller prism.
</em>
<em />
<em />
<em>Let the dimension of one side of the smaller prism be: l and w</em>
<em>Let the dimension of one side of the bigger prism be: L and W</em>
<em />
So, we have:
The area of these corresponding sides are:
---- the first
While, the area of the second is:
The ratio of these two sides are:
<em>This gives</em>
Cancel out common terms
Express as fractions
Also, we have:
This gives
Cross multiply
Hence, option (c) is true

Answer:
x=14
Step-by-step explanation:
1 way
Step 1: Subtract 3/4x from both sides.
1/4x − 5 − 3/4x=3/4x−12−3/4x
−1/2x−5=−12
Step 2: Add 5 to both sides.
−1/2x−5+5=−12+5
−1/2x=−7
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−7)
2nd way
Add 5 to both sides
1/4x - 5+5 = 3/4x - 12+5
Simplify
1/4x = 3/4x -7
Subtract 3/4x from both sides
1/4x-3/4x= 3/4x-7-3/4x
Simplify
-1/2x=-7
Multiply both sides by -2
(-1/2x)(-2)=(-7)(-2)
x=14
sorry it to so long
the second picture is not acceptable
Answer:
48 people.
Step-by-step explanation:
The sequence is 3 5 7 ...
The common difference is 2 so by the 7th stop 6 lots of people have boarded and the total is:
3 + 5 + 7 + 9 + 11 + 13 = 48 people.

Hello!
You first have to find what percentage 1 question is
6 / 3 = 2
A question is 2% of the test
Divide this by 100 to get how many questions
100 / 2 = 50
There are 50 questions
The answer is 50
Hope this helps!
