Answer:

This problem requires us to calculate, the value of investment after 10 and 25 years, and also tell the time after which intial investment amount will double. Investment rate and initial investment amount is given in the question.

Value of investment after 10 year = 2000(1+7%)^10 = $ 3,934

Value of investment after 25 year = 2000(1+7%)^25 = $ 10,855

Time after which investment amount double (n)

4000 = 2000 (1.07)^n

Log 2 = n log 1.07

n = 10.2 years

What is the surface area of the figure?<br> 240<br> 48<br> 192
Ulleksa [173]

Answer:

240 cm²

Step-by-step explanation:

We are required to determine the surface area of the figure;

To get the area we add the are of all the surfaces;

Area of triangle;

Area = 0.5 × b × h

There are two triangles;

Therefore;

Area of the two triangles;

Area = 0.5 × 6 × 8 × 2

        = 48 cm²

Area of the rectangles;

Area of a rectangle = Length × width

Area of the first rectangle;

 = 6 cm × 8 cm

 = 48 cm²

Area of the second rectangle

  = 8 cm × 8 cm

  = 64 cm²

Area of the third rectangle

 = 10 cm × 8 cm

 = 80 cm²

The total surface area will be;

 Area = 48 cm² + 48 cm² + 64 cm² + 80 cm²

          = 240 cm²

30% = 0.3

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Solution:

To write percent to decimal, divide the number by 100.

$30\%=\frac{30}{100}

       $=\frac{30\div10}{100\div 10}

       $=\frac{3}{10}

       = 0.3

30% = 0.3

Average use of water each day = 90 gallons

30\%  \ \text{of} \ 90=0.3 \times 90

                = 27

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
