The resulting figure is a right angled triangle shown below

$Apply the Pythagorean theorem to find out the magnitude of the resultant vector $A B$ in the triangle $A B C$ as follows -$$\begin{aligned}&A B^{2}=B C^{2}+C A^{2} \text { (Hypotenuse }{ }^{2}=\text { Base }^{2}+\text { Adjacent }^{2} \text { ) } \\&=7.4^{2}+9.2^{2} \\&=139.4 \\&A B=11.806777 \\&\quad A B \approx 11.8 \mathrm{~km} \text { (Rounded off to the nearest tenth) }\end{aligned}$

Pizzazz pizza sells a small pizza for 10.99. it has a diameter of 10 in. what is the pric per sqaure inch

Nookie1986 [14]

Area of a circle = pi * r^2

Radius (r) = ½ * diameter

½ * 10 = 5

A= pi * 5^2

25 * pi = 78.54 sq inches

10.99 / 78.54 = about 14 cents per sq in (13.99)

Eleven is 20% of ____

ollegr [7]

Convert to a decimal which would be 0.55 (11/20).

Then you want to multiply 0.55 by 100 (which is a whole number, all % is going to come from 100) to convert to a full % -> 0.55*100

Then you will simplify 0.55*100

You answer will be 55%.
