Answer:
23.9
Step-by-step explanation:
His route from school to Rhianna's house to his house forms a triangle in which the sides are 7 miles and the hypotenuse is unknown. Solving using the Pythagorean theorem, we find the route from Rhianna's house back home is 7^2+7^2=x^2.
Rounding to the nearest tenth, we now know this route is 9.9 miles. Adding the total distances from each location, we get an answer of 7 + 7 + 9.9 = 23.9.
The equivalent is 60 over a hundred
Answer:
H
Step-by-step explanation:
Its H because a square has 4 sides and 58 divided by 4 is 14.5
The computation shows that the placw on the hill where the cannonball land is 3.75m.
<h3>How to illustrate the information?</h3>
To find where on the hill the cannonball lands
So 0.15x = 2 + 0.12x - 0.002x²
Taking the LHS expression to the right and rearranging we have:
-0.002x² + 0.12x -.0.15x + 2 = 0.
So we have -0.002x²- 0.03x + 2 = 0
I'll multiply through by -1 so we have
0.002x² + 0.03x -2 = 0.
This is a quadratic equation with two solutions x1 = 25 and x2 = -40 since x cannot be negative x = 25.
The second solution y = 0.15 * 25 = 3.75
