Answer:

(x+16)^2=20^2+x^2

Step-by-step explanation:

Given there was no bending of the tree, the Pitagorean Theory would help finding the value of the trees hight.

x^2+32x+16^2=400+x^2

32x=(20-16)×(20+16)

x=144/32

x=4m and 50cm

A caterer prepares four times as many pizzas as she usually prepares for a large party. The caterer usually prepares 6 pizzas. T

lilavasa [31]

Let's take this problem step by step:

Step 1: First, the problem states that the caterer prepares four times as many pizzas as she usually prepares for a large party. It also states that she usually prepares six pizzas.

Step 2: 6 x 4 = 24

Step 3: The caterer estimates that each party guest will eat 1/4 of a pizza.

Step 4: 24 pizzas divided by 1/4 of a pizza is equivalent to 24/(1/4)

Step 5: You can take the reciprocal of 1/4 and multiply instead.

Step 6: 24 x 4 = 96

The answer is 96 party guests.
