This is the way we are going to solve it.

1h = 60m ----------Steps

1. 7/8w=(1+1/6)h

2. 7/8w=(6/6+1/6)h

3. 7/8w=7/6*60m

4. 7/8w=(7*6*10*m)/6

5. 7/8w=70m

6. m=(7/8w)/70

<span>7. m=1/80w

Answer: Melinda paints 1/80 of the wall in 1 minute.

Happy studying ^-^

1 1/6 hour = 70min
7/8 of wall in 70min
x wall in 1min

Proportion:
7/8 - 70
x - 1
Cross multiplication:

7/8 = 70x divide by 70

x = 1/80

In 1 min Melinda will paint 1/80 of a wall.

For the given table of values for a polynomial function, where must the zeros of the function lie?

Jet001 [13]

Answer:

A. Between 3.0 and 3.5 and between 4.0 and 4.5

Step-by-step explanation:

The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either $f(x)$ goes from a negative value to a positive value or vice versa.

From $x=3.0$ and $x=3.5$ , the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.

From $x=4.0$ and $x=4.5$ , the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
