The amount of energy needed is 110 calories. We know this by dong the following:
<span>Q=20×0.11×<span>(75−25)</span></span>
<span>⇒Q=20×0.11×50</span>
<span>⇒Q=110<span> cal
Bu doing this you have the required heat represented as Q that is supposed to raise the temperature of fork that will be equivalent to the mass multiplied by the specific heat and also by the change in temperature</span></span>
There will be 6 bands competing in the finals.
To find 15% for the finals, you need to multiply the total number of bands by 0.15. There are 41 total bands.
41 x 0.15 = 6.15 or about 6 bands
Probability is the study of determining the chances of an event being successful or not. To determine the probability of, say, 5 events happening, you would have to add their individual probabilities. For the probability of household having less than 3 televisions, you add the data for 2, 1 and 0 televisions.
Total Probability = 3% + 11% + 28% = 42% (or 0.42 if in decimal form)
Is there supposed to be a picture or a multi choice answer because there is none.Sorry
I just solved it and I'm pretty sure its only one solution, I took the bottom equation multiplied it by -3 then i canceled out the equations and got 9. So that would make it C.
