There are 12 donuts in a box, and Claire at 2. Approximately what percent of the donuts remain in the box? (Round to the nearest
skelet666 [1.2K]

Answer:

83% remains in the box

Step-by-step explanation:

Here, we are interested in calculating the percentage of donuts remaining in the box.

From the question, we are told that 2 was eaten, the number of donuts left = 12-2 = 10 donuts

The percentage of donuts left would be;

Number of donuts left/Total no of donuts * 100%

= 10/12 * 100 = 83.33

Which is 83% to the nearest whole number percentage

5. find the total area of the figure below
jok3333 [9.3K]

Answer:

134 ft^2 the total area of the given figure.

Step-by-step explanation:

Length of the bigger rectangle = 13 ft

Breadth of the bigger rectangle = x

Area of the bigger rectangle = A = 13 ft × x

Length of the smaller rectangle = 5ft

Breadth of the smaller rectangle = y = 6 ft

Area of the smaller rectangle = a = 5ft × 6ft

from the figure :

x + y = 14

x = 14ft - 6 ft = 8 ft

Total area of the figure = A + a

=13 ft\times 8 ft+5ft\times 6ft=134 ft^2

134 ft^2 the total area of the given figure.
