Answer:
meters per minute
Step-by-step explanation:
<u>Given:</u>
<u>Substitute r=5:</u>
<u>Differentiate both sides:</u>
<u>Solve for dh/dt:</u>
Therefore, the height of the water is increasing at a rate of meters per minute.
Answer:
<h2> <em><u>180</u></em><em><u>0</u></em><em><u>0</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em>
Back of lot of the trapezoid = 175
Front of lot of the trapezoid = 185
Length of lot of the trapezoid = 100
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
Area of the given trapezoid
- <em>[</em><em>On</em><em> </em><em>putting</em><em> </em><em>values</em><em>]</em>
- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>
= 360 × 50
- <em>[</em><em>On</em><em> </em><em>multiplying</em><em>]</em>
= 18000
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em>
<em><u>The</u></em><em><u> </u></em><em><u>required</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>given</u></em><em><u> </u></em><em><u>trapezoid</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>180</u></em><em><u>0</u></em><em><u>0</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
All Teachers are picky ,anyways here is the answer A = bh
Plug in what we know:
18 1/3 = 3 1/3b
Divide 3 1/3 to both sides:
(18 1/3) / (3 1/3) = b
Convert both of them into improper fractions:
55/3 / 10/3 = b
Flip the 2nd fraction and multiply:
55/3 * 3/10 = b
Multiply the numerators and denominators together:
165/30 = b
Convert to a mixed number:
b = 5 1/2
The segments AE, EC, AD and DB are in proportion.
Therefore we have the equation:
AE = 4ft, AD = 8ft and BD = 2ft. Substitute:
<em>multiply both sides by 2</em>
Answer:
1. cm
2. 318.198 ft^2.
Step-by-step explanation:
Hmm. Very stuck. We'll just take it slow. :)
For the first one, we'll just square the bottom of the parallelogram, because
it's a square. The answer is above.
The second is a bit more complicated. The formula for the area of a parallelogram is (base) x (height)= A(area), but that will be of no use until we know the height (the dashed line on the left).
So, do let's go about finding the height with a 45-45-90 triangle.
The way these work is that the two short sides are equal to x, and the longer one is . So, in essence, .
15/=10.61
Both of the other two sides (one being the height) are 10.61 ft long.
Multiply that by 30:
30 x 10.61= and you get 318.198 ft^2.
