The average speed of blood in the aorta is 0.2833 m/s
Speed is the ratio of distance travelled to time taken. It is given by:
Speed = distance / time
From the question, to calculate the average speed:
Average speed = Volume rate / cross sectional area
Average speed = 8.5 * 10⁻⁵ / (3 * 10⁻⁴) = 0.2833 m/s
The average speed of blood in the aorta is 0.2833 m/s

Answer:
29.2
Step-by-step explanation:
Mean = 21.4
Standard deviation = 5.9%
The minimum score required for the scholarship which is the scores of the top 9% is calculated using the Z - Score Formula.
The Z- score formula is given as:
z = x - μ /σ
Z score ( z) is determined by checking the z score percentile of the normal distribution
In the question we are told that it is the students who scores are in the top 9%
The top 9% is determined by finding the z score of the 91st percentile on the normal distribution
z score of the 91st percentile = 1.341
Using the formula
z = x - μ /σ
Where
z = z score of the 91st percentile = 1.341
μ = mean = 21.4
σ = Standard deviation = 5.9
1.341= x - 21.4 / 5.9
Cross multiply
1.341 × 5.9 = x - 21.4
7.7526 = x -21.4
x = 7.7526 + 21.4
x = 29.1526
The 91st percentile is at the score of 29.1526.
We were asked in the question to round up to the nearest tenth.
Approximately, = 29.2

Answer:
x=½
Step-by-step explanation:
<em>3</em><em>x</em><em>-</em><em>9</em><em>=</em><em>x-8</em><em>(</em><em>Group</em><em> </em><em>like</em><em> </em><em>terms</em><em>)</em>
<em>3</em><em>x</em><em>-</em><em>x</em><em>=</em><em>-</em><em>8</em><em>+</em><em>9</em><em>(</em><em>You </em><em>will </em><em>subtract</em><em> </em><em>x</em><em> </em><em>which</em><em> </em><em>is </em><em>also</em><em> </em><em>1</em><em>x</em><em> </em><em>from </em><em>3</em><em>x</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>going</em><em> </em><em>to</em><em> </em><em>be </em><em>2</em><em>x</em><em> </em><em>Then </em><em>you </em><em>will</em><em> </em><em>add</em><em> </em><em>-</em><em>8</em><em> </em><em>to</em><em> </em><em>9</em><em> </em><em>making </em><em>it</em><em> </em><em>1</em><em>(</em><em>positive</em><em>)</em><em>)</em><em>.</em>
