vredina [299]

Answer:

$11500

Step-by-step explanation:

Given

Tax amount=$1437.50

Tax percentaege=12.5%

So, we have to find the price of motorcycle whose 12.5% is 1437.50

Mathematically writing,

Let

x be the price of motorcycle without tax

then, the equation will be written as:

x*0.125=1437.50

x= 1437.50/0.125

x=11500

So the price of motorcycle without tax was $11500..

"a man drove 10 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place o

Mariulka [41]

Answer:

11.2 miles

Step-by-step explanation:

We can create a triangle from the information given.

We can call the starting point (0,0) in the coordinate system.

10 mi east - 10 miles to the right. then,
5 mi north - 5 miles above

See the attached picture. The direct distance is labeled as x.

Now we need to find x using pythagorean theorem.

Pythagorean Theorem = leg²+leg²=hypotenuse²

Solving for x:

$10^2+5^2=x^2\\100+25=x^2\\125=x^2\\x=\sqrt{125}\\x=11.18$

Rounding to nearest tenth, we have 11.2 miles
