80% of 90 is 72 and half of 140 equals 70. So 80% of 90 is bigger
<span>Total Distance = x
Luis walked one-eighth of x = x(1/8) = x/8
He still need to walk = Total Distance - Distance covered
He still need to walk = x-x/8
He still need to walk = (8x-x)/8
He still need to walk = 7x/8
He still need to walk = x(7/8)
He still need to walk seven-eighth of the total distance.

Answer:
A.) -0.015x² + 0.365x + 1.116
Step-by-step explanation:
Using a graphing calculator, the quadratic regression equation obtained for the data in the table is :
General form of a quadratic regression equation :
A + Bx + Cx²
A = 1.115714
Bx = 0.3647x
Cx² = - 0.015x²
Hence, rounding to the appropriate number of decimal places, the quadratic regression equation becomes ;
-0.015x² + 0.365x + 1.116
Answer:
The answer to your question is given below.
Step-by-step explanation:
Let the total number be U.
From the question given above, we were told that any number of B is 50% of the total number (i.e U).
Now, we shall determine the the total number (U) in terms of B.
50% of U = B
50/100 × U = B
50U / 100 = B
Cross multiply
50U = 100B
Divide both side by 50
U = 100B/50
U = 2B
Thus, the total number is 2B
Finally, we shall determine the answer to the question:
111 is 50% of ___
B = 111
Total number (U) = 2B
Total number (U) = 2 × 111
Total number (U) = 222
Therefore,
111 is 50% of 222
