Answer: 44%
Step-by-step explanation:
There are 25 squares in the rectangle. This means that the percentage of each square is:
= 1/25 * 100
= 4%
There are 11 shaded squares so the percentage represented is:
= 11 * 4%
= 44%
Answer:
The required probability is 4/7.
Step-by-step explanation:
The sample space for the experiment is: { BB, BR, RB, RR }
The outcome of the event we require is: { BR, RB }
The probabilities for each outcome is given as:
BB: 3/7 x 2/6 = 1/7
BR: 3/7 x 4/6 = 2/7
RB: 4/7 x 3/6 = 2/7
RR: 4/7 x 3/6 = 2/7
Adding the probabilities we have:
{ BR, RB} = 2/7 + 2/7 = 4/7
That's it!
Answer:
$36.80
Step-by-step explanation:
15% of 32 = 0.15x32 = $4.80
32+4.80 because it was a tip being added to the bill
=36.80
Answer:
a. Scale Perimeter : 2.5 centimeters
Actual Perimeter : 13 centimeters
Actual Area : 10.5 square centimeters
b. Actual Perimeter : 130 mm
Actual Area : 1,050 mm
Step-by-step explanation:
a. 2.5 mm = 0.25 cm
2 (1 + 0.25) = 2.5
2 (3.5 + 3) = 13
3.5 x 3 = 10.5
b. 3.5 cm = 35 mm 3 cm = 30 mm
2 (35 + 30) = 130
35 x 30 = 1050
