Students put the same amount of water into four beakers and heat them to 60 °C. They then place each beaker in different locations in the classroom. After 5 min, the students measure the temperature of each beaker of water. The results are shown in the bar graph to the right. Based on the graph, describe what the temperature of the air in the back corner.

x + 4/7

step-by-step explanation:

use cymath

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
