Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.
Anton [14]

Option C:

Area of the wall =94\frac{15}{16} square feet

Solution:

Length of the wall = 12 \frac{1}{4} feet

Width of the wall = 7 \frac{3}{4} feet

Area of the wall = length × width

                          $=12 \frac{1}{4}\times 7 \frac{3}{4}  

Convert mixed fraction into improper fraction.

                          $=\frac{12 \times 4+1}{4}\times  \frac{7\times 4+3}{4}

                          $=\frac{49}{4}\times  \frac{31}{4}

                          $=\frac{1519}{16}

Convert improper fraction into mixed fraction.

                          $=94\frac{15}{16}

Area of the wall =94\frac{15}{16} square feet

Option C is the correct answer.

Help please it would help my grade alot
Alexxandr [17]

Answer:

It cooled 58.4 degrees

Step-by-step explanation:

T(t) = 68 + 144e ^(-.052t)

We want to find the value when t= 10

T(10) = 68 + 144e ^(-.052*10)

        = 68 +85.611

 T(10)         =153.611

We also need to know

T(0)= 68 + 144e ^(-.052*0)

       =68+144

        =212

We want to know how much it cools

That would be the temperature at  time 0 minus the temperature at  time 10


T(0) - T (10)

212-153.611

58.389

To the nearest tenth

58.4 degrees
