If we divide the area we have to cover by the area of a piece, we will get the number of pieces needed:
Answer:
the answer is the 3rd option
range = { 33, 54, 75 }
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Y= -x^2. That’s the answer
Hello! Your answer would be -10 degrees.
The temperature starts out eight degrees below zero. 0 - 8 = -8. Therefore, it starts off at -8 degrees.
Then, it increases by 5 degrees. Therefore, add 5 to -8. -8 + 5 = -3. Therefore, the next day has a temperature of -3 degrees.
Finally, it decreases by 7 degrees. -3 - 7 = -10. This shows us our final result - -10 degrees.
Hope this helps!
