Answer:
0.66
Step-by-step explanation:
Note: ALWAYS divide the percentage by 100.
Answer:
375000 ft^2
Step-by-step explanation:
From the statement that we have that it would be 1 time the length and 2 times the width because one side is not necessary and also we must take into account that it would be divided by 3 equal enclosures therefore we will use 1000 feet (3000/3) so Therefore, the perimeter would be equal to:
1000 = l + 2 * w
we solve for w:
l = 1000 - 2 * w
Also the area is equal to:
A = w * l
replacing:
A = w * (1000 - 2 * w)
A = 1000 * w - 2 * w ^ 2
We derive:
A '= 1000 - 4 * w
Let's equal 0:
1000 - 4 * w = 0
w = 1000/4
w = 250
replacing and we calculate l:
l = 1000 - 2 * 250
l = 500
A = 250 * 500
A = 15,000 ft ^ 2
Which means that for each subdivision the maximum area would be 125000 square feet and the total would be:
125000 * 3 = 375000 ft ^ 2
Answer:
4. 118 kg
w = 450 j , d = 3.8 m
w = mgh ⇒mg = w / h ⇒m = 450/3.8 = 118 kg
5. 9806.65 Joules
6. 25 J
Multiplying the number by 1,000
so what they mean by "similar" is just that the shapes are the same but different sizes. since we have the measurement for sides PM, MN and TQ, we can figure it out. we have to think of it as a ratio. so PM/TQ = MN/QR. if we plug the amounts in its 57/23 = 40.3/QR. then we cross multiply. so thats 23 x 40.3 which is 926.9. then we divide 926.9 by 57 which is 16.2614035. rounding to the nearest tenth is 16.3
