Belinda bought a car for 10% off the $21,957.68 sticker price. The sales tax was 6.5% of the sale price. She had to pay a $528.0
babymother [125]

Answer:

$21,574.43

Step-by-step explanation:

To start off, we need to take 10% off of the starting price of $21,957.68. We can do that by multiplying that number by 0.10. The work is shown below...

(21,957.68) x (0.10) = 2,195.77

Now we can take the number 2,195.77 and subtract that from our starting price.

21,957.68 - 2,195.77 = 19,761.91 (this is our price after the 10% sale)

Next, we need to add on the sales tax. We simply multiply 19,761.91 by the decimal version of 6.5% which is 0.065.

(19,761.91) x (0.065) = 1,284.52

Now we add that number to 19,761.91

19,761.91 + 1,284.52 = 21,046.43

Since we have our current cost after sales tax, we now just need to add the $528 license fee...

21,046.43 + 528 = $21,574.43

on a coordinate grid, her house is located at (1,2) and the park at (5,5) what is the shortest distance from her house to the pa
nadya68 [22]
To solve, use the distance formula: d= \sqrt{(x_1+x_2)^2+(y_1+y_2)^2}. Using your values of x and y, you get d= \sqrt{(1+5)^2+(2+5)^2} = \sqrt{6^2+7^2} = \sqrt{36+49} = \sqrt{85}, which is approximately 9.22. This means your shortest distance is √85≈9.22

Solve the following equations <br> 5^2x-2(5^x)-15=0
castortr0y [4]

Answer:

x = 1

Step-by-step explanation:

{5}^{2x}  - 2( {5}^{x} ) - 15 = 0

( {5}^{x}  {)}^{2}  - 2 \times  {5}^{x}  - 15 = 0

{t}^{2}  - 2t - 15 = 0

{5}^{x} t =  - 3 \:  \: .5

{5}^{x}  = 5

x = 1
