Answer:
159.25 ft²
I hope this helps! :)
Step-by-step explanation:
Formulas:
For the Rectangle... <em>bh = a</em>
For the Semicircle... 1/2 × πr²
Step 1:
Solve the area for the rectangle:
<em>bh = a</em>
10 × 12 = 120
a = 120 ft²
Step 2:
Solve the Area for the Semicircle:
1/2 × πr²
1/2 × 3.14 = 1.57
Radius = Diameter ÷ 2
10 ÷ 2 = 5
Radius = 5
1.57 × 5²
1.57 × 5 × 5
= 39.25 ft²
Step 3:
Add the two areas together:
120 + 39.25 = 159.25 ft²
3km =m 3 x 1000m = 3 x 10 ^3m
expansion = 3x 10^3m + 15 x 10 cm
Answer:
The second graph is the answer.
Answer: 10
Step-by-step explanation: if you multiply the 11 gallons of gasoline times 2 to get 22 gallons of gaso line then you have to multiply the 5 oz of oil times 2 to get 10 oz of oil
- Ana has the greater median
- Ana also has the greater mean.
Averagely, Ana practiced for a greater amount of time each day.
<h3>What is the Mean and Median of a Data Set?</h3>
- Mean = sum of data points / number of data points.
- Median = center/middle of the data distribution.
Mean for ana= (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6
Mean for tara= (20 + 20 + 30 + 30 + 45 + 45 + 45 + 70 + 70 + 70 + 75 + 90 + 90 + 120)/14 = 58.6
Median for ana= 70
Median for tara= (45 + 70)/2 = 57.5
Ana has the greater median and also has the greater mean.
Averagely, we can conclude that ana practiced for a greater amount of time each day.
