That is a description of the formula for the rectangle rule using left endpoints.
Answer:
14.6
Step-by-step explanation:
Make 2 equations one for the total downloads and the other for total size
Let x = number of standard downloads and y = number of quality downloads.
x + y = 840
2.7x + 4.4y = 2846
from first equation y = 840 -x Now plug this into the second equation:_
2.7x + 4.4(840 - x) = 2846
-1.7x = -850
x = 500 Number of standard versions downloaded = 500 Answer
Answer: The size of the TV along it's diagonal is 47 inches
Step-by-step explanation: The rectangle shaped Television has it's dimensions given as,
Length = 41 in
Width = 23 in
The length of the diagonal is also the Hypotenuse, since the the diagonal line divides the rectangle into two right angled triangles. With that bit of information, we can calculate the hypotenuse by using the Pythagoras theorem which states that
AC² = AB² + BC²
Where AC is the hypotenuse (or diagonal) and AB and BC are the other two sides.
Therefore, AC² = 23² + 41²
AC² = 529 + 1681
AC² = 2210
Add the square root sign to both sides of the equation
AC = √2210
AC = 47.0106
(The approximate value is 47)
Therefore the size of the TV to the nearest inch equals 47 inches
157.5 square feet.
you multiply the base which is 9 by the height which is 17.5
