Kathy uses 8.6 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

Kathy uses 1.72 pint of white paint

Step-by-step explanation:

Total amount of paint ( Blue and white paint)= 8.6 pints

Amount of  blue paint=4/5 x 8.6 = 6.88 Pints

amount of white paint = Total amount of paint - amount of blue  paint

= 8.6 pints - 6.88 pints

=1.72 pint of white paint

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
