Answer: 9 meters
To answer this question you need to know the formula to calculate the area of a square. Square has same side length so the area is: length x length.
Then the calculation would be:
Area= length x length
81m2= length x length
Length ^2= 81 m2
Lengtj= <span>√81 m2</span>
Length= 9 meters
Answer:
If your saying that 15 is m (or the slope) I can help you there to find the equation (y=mx+b form), but i will need more detail, type more details in the comments below and ill help you from there.
Amount of decreased water = 3/10
Then, it would be 3/10 * 100 = 30%
So, your answer is 30%
The lateral area of the prism is given by:
LA=[area of the two triangles]+[area of the lateral rectangles]
hypotenuse of the triangle will be given by Pythagorean:
c^2=a^2+b^2
c^2=6^2+4^2
c^2=52
c=sqrt52
c=7.211'
thus the lateral area will be:
L.A=2[1/2*4*6]+[6*8]+[8*7.211]
L.A=24+48+57.69
L.A=129.69 in^2
The total are will be given by:
T.A=L.A+base area
base area=length*width
=4*8
=32 in^2
thus;
T.A=32+129.69
T.A=161.69 in^2
10m/s
32m/s
83m/s
None of these
Answer :
C
Solution :
At any instant x2+y2=52
Differentiating w.r.t. time 2xxdt+2ydydt=0
Here dxdt=2,dydt=u⇒u=83m/s
