B- $3.00
19/1.14 = .06
.06 x 50 = $3.00
Since it is about only the outer part of the aquarium which is made of glasses we need to calculate the total surface area.
Surface area of the base = 4*3 = 12 square feet
Surface area of the shorter length of wall = 3*2 = 6 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
6*2 = 12 square feet
Surface area of the longer length of wall = 4*2 = 8 square feet
since it has another wall in opposite side. It has to be multiplied with 2.
8*2 = 16 square feet
Therefore the total surface area that need to be covered with glasses
12+12+16 = 40 square feet
Answer:
The answer is 1122.
Step-by-step explanation:
First, multiply 34 by 3. That gives you 102.
Then multiply 34 by 3 again. But when you're writing this down in calculations, put a zero in the ones column then write your answer. (I'll show an example of what this looks like at the bottom.
Then, add your answers and you'll have your answer...

x - 10 + x - 11 + 3x + 6 = 180
5x -15 = 180
5x = 195
x = 39
7b)
y = 3x + 6
y = 3(39) +6
y = 117 + 6
y = 123
1.5 as a mixed muber is 1 and 1/2, as an improper fraction it could be 3/2
