Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx
The heart beat rate is 70beats/minute with 80ml of blood pumped every beat. Then, the <span>volume of blood your heart pumps in one minute would be:
volume of blood per minute= volume per beat * beat per minute
</span>volume of blood per minute= 80ml/beat * 70beat/minute= 560ml/ minute<span>
</span>volume of blood per hour would be: 560ml/minute * 60 minute/hour= 33.600 ml/hour

Step-by-step explanation:
Answer:
It's not a right angle.
Step-by-step explanation:
Remark
There's a second restriction on the problem. The Perimeter is 22 cm.
AB = 8
BC = 5
AC = 9.4
When you add these up, you get 8 + 5 + 9.4 which is 22.4
You may think this is close enough. In this case it is not. Either the perimeter has to 22.4 or the hypotenuse has to be reduced. Let us say it is close, but not close enough.
When you use other methods, you find out that the right angle is actually 90.4 degrees
