Answer:

Phil has 24 more rocks than Peter

Step-by-step explanation:

Lets make Peter x

Then Phil = 3x because Phil has 3 times as many rocks as Peter.

If the sum of the rocks they both have is 48, add them together.

3x+x=48

Solve the equation.

4x=48

Divide by 4.

x=12

Peter has 12 rocks, Phil has 36 rocks

36-12=24

timama [110]

Answer:

10.7 feet

Step-by-step explanation:

The ladder, the ground and the wall form the shape of a right angled triangle as shown in the image below.

The hypotenuse of the triangle is 14 feet (length of ladder)

The base of the triangle is 9 feet long (the distance from the base of the ladder to the wall)

We need to find the height of the triangle. We can apply Pythagoras rule:

$hyp^2 = a^2 + b^2$
