Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

\frac{InitialValue}{100} = \frac{x}{TaxPercentage}

Substitute in our values, using No.1 as our example.

\frac{123.01}{100}  = \frac{x}{7.5}

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24

What is the most precise classification of the quadrilateral formed by connecting in order the midpoints of the figure below? Sh
AlekseyPX

Answer:

Rhombus

Step-by-step explanation:

The given trapezoid has vertices at M(-4,0), J(-2,4), K(2,4), and L(4,0).

Use the midpoint formula: (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

To obtain the midpoint of MJ:

A=(\frac{-4+-2}{2},\frac{0+4}{2})=(-3,2)

Similarly, the midpoint of of JK is B=(0,4), the midpoint of  KL is C=(3,2), and the midpoint of LM is D=(0,0).

Now use the slope formula;

m=\frac{y_2-y_1}{x_2-x_1}

To find the slope of AB = \frac{4-2}{0--3}=\frac{2}{3}

The slope of BC =\frac{2-4}{3-0} =-\frac{2}{3}

The slope of CD= \frac{0-2}{0-3}=\frac{2}{3}

The slope of AD=\frac{0-2}{0--3}=-\frac{2}{3}

We can see that the slope of the opposites sides are parallel, CD is parallel to AB and AD is parallel to BC.

The product of the slopes of the adjacent sides is not -1.

Hence the shape formed by connecting the midpoint of the isosceles trapezoid is a parallelogram.

Obviously the side lengths are equal since we connected all midpoints.

The parallelogram is a rhombus.

4 hundred-dollar bills 23 ten-dollar bills, 17 one-Dollar bills 46 Dimes And 19 pennies How much? Please help
Darina [25.2K]
Hundred dollar bills is 100 dollars so if you have four of them you get 400
ten dollar bills is 10 dollars so if you have 23 of them you have 230 
one dollar bills is 1 dollar so if you have 17 of them you 17 dollars 
400+230+17= 647
One dime is equal to 10 cents so if you have 46 of them you have $4.60 
One penny equals 1 cent so 19 pennies equal 19 cents  
$4.60+.19= $4.79 
$647+$4.79= $651.79<---- that's your answer
