Let's find the total cost before the tax and tip.
14+16+2*1.25+2*4.25 = $41
The tip is added before the tax so let's calculate it first.
1.15 * 41 = $47.15
Now add the 7% tax.
1.07 * 47.15 = $50.45
We have that
<span>6x^2 +12x+5=0
to find the x intercepts resolve the second order equation
x=[-b(+-)</span>√(b²-4ac)]/2a
x1=[-12(+)√(12²-4*6*5)]/12---> [-12(+)√(144-120)]/12
=[-12(+)√(24)]/12--------> -1+√24/12-----> -1+√6/6
x1=-1+√6/6
so
x2=-1-√6/6
see the graph in the attached figure
<span>
the answer is
</span>the x-intercepts for the graph of the quadratic function in <span>exact form are
</span>x1=-1+√6/6
x2=-1-√6/6
Answer:
4+5+.8+.00+.003 if I remember correctly
the answer i got was 5% , because all you have to do is perform a proportion . you put $400 which is what avery made over the total money of the sale which is $8,000 . then you put n the variable over 100 so you can find the percentage of her commission . now you have to cross multiply , so you would multiply $400 and 100 . & $8,000 with the variable n . in the end you'll get 400*100= 40,000 and 8,000n= 8,000n . now you would divide 40,000 by 8,000 to get rid of the 8,000 off the variable . so 40,000/8,000= 5 . so the percentage of her sale is actually hers is only 5% .
Answer:
12 meters far.
Step-by-step explanation:
The question translates to 10+2. The word problem states that the height of the platform is 10 meters. That means we can say that he'd have already traveled 10 meters down when he dived. And the problem also states that the diver goes two meters under the water, meaning that he had traveled 2 meters, in addition to the 10 meters. And so, we add the 10 and 2 to get 12 meters in total.
