Answer:

Ellen have left 56 glasses to wash.

Step-by-step explanation:

Given that:

Number of glasses to be washed = 175

Percentage of glasses Ellen washed = 68%

Number of glasses Ellen washed = $\frac{68}{100}*175$

Number of glasses Ellen washed = 119

Number of glasses left = Total glasses - Number of glasses washed

Number of glasses left = 175 - 119 = 56

Hence,

Ellen have left 56 glasses to wash.

Arte-miy333 [17]

The amount of paint required by Madeline will be 0.8325 gallons

<h3>What amount of paint will be required by Madeline?</h3>

Given that

$1cm=1.5ft$

We will first find the area of the wall

Area of the wall = Area of trapezoidal shape+ Area of triangular shape

Area of trapezoid = $\dfrac{a+b}{2} \times h$

a= 4cm

b=14cm

h=10cm

putting this values

$A=\dfrac{4+14}{2} \times 10$

$A=90cm^{2}$

Area of triangular shape= $\dfrac{1}{2} \times width\times height$

width=14cm

height=8cm

putting the values

$A=\dfrac{1}{2} \times 14\times 8=58cm^{2}$

$Total area of the wall= 90+58=148cm^{2}$

since we have

$1cm=1.5ft$

$148cm^{2} = 148\times (1.5)^{2} =333 ft^{2}$

Now

$1gallon = 400ft^{2}$

so for $333 ft^{2}$ amount of paint in gallons required will be

$1ft^{2} =\dfrac{1}{400} gallons$

$333ft^{2} =\dfrac{333}{400} gallons=0.8325gallons$

Thus the amount of paint required by Madeline will be 0.8325 gallons

This table shows values represented by an exponential function.

Bad White [126]

Answer:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5

Step-by-step explanation:

For this cae we know that the average rate of change of a function is given by this general expresion:

$m = \frac{f(b) -f(a)}{b-a}$

For this special case from the info of the table we have:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5
