Town Hall is located 4.3 miles directly east of the middle school. The fire station is located 1.7 miles directly north of Town

Maksim231197 [3]

Answer:

2.1 miles

Step-by-step explanation:

you can see a drawing of the situation in the attached picture (you need to draw all the places mentioned and the distance between them),

this way we can form a right triangle between the school and the hospital with measures of sides: 1.7 and 1.2 miles

and the green line is the straight line between the school and the hospital, so you need pythagoras to find the value:

$\sqrt{1.7^2+1.2^2}\\=\sqrt{2.89+1.44}\\=\sqrt{4.33} \\ =2.081$

rounding to the nearest tenth:

2.1 miles

Sergio [31]

Answer: The required expression would be $0.8p$ .

Step-by-step explanation:

Since we have given that

Let the regular price of an item be 'p' dollars.

Discount % = 20%

So, Amount of discount would be

$\dfrac{20}{100}\times p\\\\=0.2p$

So, the expression represents the sale price would be

$p-0.2p\\\\=0.8p$

Hence, the required expression would be $0.8p$ .
