Answer: he has read 15% and still needs to read 85%
Step-by-step explanation: 300/20 is 15 so that’s the percent he has read. 100-15=85 so that’s the percent he still has left to read

Answer: D) pairs 2 and 4</h3>
Pair 2 shows one figure rotated 180 degrees compared to the other, and translated as well. So they are congruent (ie the same).
Pair 4 shows one triangle reflected over the vertical line x = 22 to get the other triangle; which shows they are the same triangle.
The other pairs are not congruent. You can show that the areas of each figure being different is enough to prove they aren't the same figure.
the first question...the answer is 10
see;x is our unknown number
so;27-2=25
x + 15=25
x = 25-15
x =10
10 + 15 = 25
25 + 2 = 27
The mean is 85.2
Explanation:
Add all the numbers together
98+78+84+75+91=426
Divide the sum by the amount of numbers you added together
426/5= 85.2
