For a road trip a car of travelers can take the direct route or the scenic route. The scenic route takes 25% longer than the dir
MariettaO [177]

Answer:

the scenic route take 6h 40m

Step-by-step explanation:

first we have to make an equation that represents the relationship of each route

x = scenic route

y = direct route

x = y + y * 25/100

now we have to make an equation that represents the routes over time

x + y = 12

we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation

x + y = 12

(y + y * 25/100) + y = 12

2 y + 0.25 y = 12

2.25y = 12

y = 12/2.25

if we spend this in minutes multiplying it by 60

y = 12/2.25 * 60 = 320 m = 5h 20m

x + y = 12

x + (5h 20m) = 12h

x = 12h - 5h 20m

x = 6h 40m

Solve the following quadratic by<br> completing the square.<br> y = x2 + 10x + 10
IgorC [24]

Answer:

<h2>         x = -5 - √15    or   x = -5 + √15</h2>

Step-by-step explanation:

y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}

<span>If the base rate of Taxation percentage is only 8%, and the item in question that is being taxed costs $30, then the answer of how much the tax will cost ends up being 8% of 30. 8% of 30 is 2.4 so 8% of $30 is $2.40. So the cost of the $30 item, including tax, is $32.40.</span>
