Beth will pay $ 405.45 for washing machine
<em><u>Solution:</u></em>
Given that, Beth is buying a new washing machine that costs $450
Cost price = $ 450
She has a 15% off coupon
So, she has a discount of 15 % of 450
<em><u>Let us find the discount rate</u></em>
Discount rate = 15 % of 450
Thus discount rate is $ 67.5
<em><u>Therefore, sales price is given as:</u></em>
sales price = cost price - discount rate
sales price = 450 - 67.5 = 382.5
Thus she pays $ 382.5
Now she must pay 6 % sales tax
Let us find the sales tax rate
Sales tax rate = 6 % of 382.5
Thus sales tax rate = $ 22.95
<em><u>How much will Beth pay for the washing machine?</u></em>
Total amount paid by Beth = sales price + sales tax rate
Total amount paid by Beth = 382.5 + 22.95 = 405.45
Thus Beth will pay $ 405.45 for washing machine
The front of the base is 1.25 ft and the total base is 14.05 ft.
<h3>How to find the side of a right triangle?</h3>A right triangle has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.
The sides CD and BD can be found using similar triangle principle.
In similar triangles, corresponding sides are always in the same ratio.
Therefore, the following proportion can be established as follows;
Hence,
cross multiply
4 × 4 = 12.8 CD
16 = 12.8CD
divide both sides by 12.8
CD = 16 / 12.8
CD = 1.25 ft
BD = 1.25 + 12.8 = 14.05 ft
Therefore, the front of the base is 1.25 ft and the total base is 14.05 ft.
