Angel ! You have a formula, and you have an example that's
completely worked out. The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.
I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.
Write the formula on the wall:
°F = (9/5) °C + 32°
A). Convert 35° C °F = (9/5)(35°) + 32°
(9/5)(35) = 63 °F = 63° + 32°
°F = 95°
____________________________________
B). Convert 80°F to °C
The formula: °F = (9/5) °C + 32°
°F = 80 80 = (9/5)°C + 32
Subtract 32 from each side: 48 = (9/5)°C
Multiply each side by 5 : 240 = (9) C
Now you take over:

C). Convert 15°C to °F.
The formula: °F = (9/5) °C + 32°
°C = 15 °F = (9/5) 15° + 32
(9/5) (15) = 27
Go ! °F =
Sanityzer, disnefeecting wipes, mops, disnifecting spray
Renewable resources:
A renewable resource is one that can be used repeatedly and does not run out because it is naturally replaced.
Nonrenewable resource:
A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
Thenks and pls mark me brainliestt :))
Answer:
Blue visible light
Explanation:
the distance between the crests of the waves is the shortest
<span>(cp of Copper = 387J / kg times degrees C; cp of Aluminum = 899 J / kg times degrees C; cp of Water = 4186J / kg times degrees C)
</span> Use the law of conservation of energy and assuming no heat loss to the surroundings, then
<span>Heat given up by copper = heat absorbed by water + heat absorbed by calorimeter
</span><span> Working formula is
</span> <span>Q = heat = MCp(delta T)
</span><span> where
</span><span> M = mass of the substance
</span><span> Cp = specific heat of the substance
</span><span> delta T = change in temperature
</span> Heat given up by copper = 0.10(387)(95 - T)
<span> Heat absorbed by water = 0.20(4186)(T - 15)
</span><span> Heat absorbed by calorimeter = 0.28(899)(T - 15)
</span> where
<span> T = final temperature of the system
</span><span> Substituting appropriate values,
</span> 0.10(387)(95 - T) = 0.20(4186)(T - 15) + 0.28(899)(T - 15)
<span> 38.7(95 - T) = 1088.92(T - 15)
</span><span> 3676.50 - 38.7T = 1088.92T - 16333.8
</span><span>1127.62T = 20010.3
