1 yard^2 = 0.8361m^2.?
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>So he spent (.625 x 400) = $250.00 per m^2. </span>
<span>He paid out (500 x 250) = $125,000 on the deal. </span>
<span>He received (500 / 0.8361) = 598.014592 yard^2 of fabric. </span>
<span>That would have cost (598.014592 x 120) = $71,761.75 locally. </span>
<span>He lost (125,000 - 71,761.75) = $53,238.25 on the deal. </span>
You can rework with the incorrect conversion factor.

I believe, dont quote me on it
Answer:
123 km/h
Explanation:
The distance between the Jeep Wrangler and the Ford Taurus is increasing.
Let us consider the north direction as positive when observing from the ground
So, the south direction will be negative
But when the observer is one of the cars the direction will be the same i.e., moving away from each other, so the velocity will be added.
Hence velocity of the Jeep relative to the Ford will be
Velocity of the Jeep + Velocity of the Ford
= 74+49 = 123 km/h
∴ Velocity of the Jeep relative to an observer in the Ford is 123 km/h
Walking at a speed of 2.1 m/s, in the first 2 s John would have walked
(2.1 m/s) (2 s) = 4.2 m
Take this point in time to be the starting point. Then John's distance from the starting line at time <em>t</em> after the first 2 s is
<em>J(t)</em> = 4.2 m + (2.1 m/s) <em>t</em>
while Ryan's position is
<em>R(t)</em> = 100 m - (1.8 m/s) <em>t</em>
where Ryan's velocity is negative because he is moving in the opposite direction.
(b) Solve for the time when they meet. This happens when <em>J(t)</em> = <em>R(t)</em> :
4.2 m + (2.1 m/s) <em>t</em> = 100 m - (1.8 m/s) <em>t</em>
(2.1 m/s) <em>t</em> + (1.8 m/s) <em>t</em> = 100 m - 4.2 m
(3.9 m/s) <em>t</em> = 95.8 m
<em>t</em> = (95.8 m) / (3.9 m/s) ≈ 24.6 s
(a) Evaluate either <em>J(t)</em> or <em>R(t)</em> at the time from part (b).
<em>J</em> (24.6 s) = 4.2 m + (2.1 m/s) (24.6 s) ≈ 55.8 m
Answer:
Explanation:
mass of displaced oil = 11 x .9
= 9.9 gm
9.9 x 10⁻³ kg
weight of displaced oil = 9.9 x 9.81 x 10⁻³ N
= .097 N .
buoyant force by oil = .097 N
weight of unknown metal = .1 x 9.8
= .98 N .
weight of metal in oil = .98 - .097
= .883 N .
