Answer:

top area = 10.125

Step-by-step explanation:

Formulas used

triangle: base × height / 2

rectangle: base × height

1.5×1.5=2.25

2.25 / 2 = triangle = 1.125

1.5×3=4.5

4.5 × 2 because we have two of the same rectangles.

4.5×2 = both rectangles = 9

add our triangle and rectangles gives our top.

9+1.125 = top = 10.125

explained in sentences:

I found the base and height of my formulas. then used a calculator to help me solve. Which got me the answer of 10.125 when I added area of two rectangles and one triangle.

Answer:

Solution is invalid

Step-by-step explanation:

Let the time when they will have the same water content be x hours

At x hours;

For the first tank, the content will be;

50 + 10x

For the second;

29 + 3x

Equating both, will give us x

29 + 3x = 50 + 10x

We will get x as a negative number here

Since number of hours can not be negative, the solution is invalid

Number 4 I have no idea how to do.

Volume is a three-dimensional scalar quantity. The cost of the glass is $1312.24.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the colony must be able to take a volume of 200,000 cubic meters, therefore, the diameter of the hemisphere will be,

The volume of Hemisphere = (2/3)πr³

200,000 = (2/3) × π × R³

R = 45.7

The area of the base of the hemisphere is,

Area of the base = πR² = π×(45.7)  = 6561.185 meters²

Given the cost of glass is $0.20 per square meter, therefore, the cost of the glass of the base will be,

Cost of glass = 6561.185 × 0.20 = $1312.24

Hence, the cost of the glass is $1312.24.
