Tree has a shadow that is 9 feet long what us is 4 feet tall and a standing next to the tree that is has a shadow that is 4.5 feet long how tall is the tree

Step-by-step explanation:

We are given the shadow of the tree = 9 feet long.

The height of the tree is = 4 feet.

Let us assume the tree with shadow 4.5 feet is h feet high.

Setting proportion now,

.

Plugging values, we get

On cross multiplication, we get

4×4.5=h×9

18=9h

Dividing both sides by 9, we get

h=2.

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
