Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
The final answer i got was D
In each arrangement, there are 10 flowers. The daisies are 2/10. multiplying 2/10 to 10, we get 2. So there are 2 daisies.
If Morita makes 4 arrangements, then the number of daisies she needs is
= 4 * 2
= 8
So she need 8 daises for here 4 arrangements.
