the variable Z is invery proportional to X. when X is 3, Z has the value 6. what is the value of Z when X = 12

MrMuchimi

"inversely proportional," please.

z = k/x

When x is 3, z = 6; find k: 6 = k/3, or k = 18.

Then z = 18/x. When x = 12, z = 18/12 = 2/3 (answer)

Ian drinks 3 \text { pints}3 pints3, start text, space, p, i, n, t, s, end text of water during a long hike. He drinks 1\dfrac12

r-ruslan [8.4K]

Answer:

$Total = 7\frac{1}{2} cups$

Step-by-step explanation:

Given

Initially, he drank 3 pints of water

Then, $1\frac{1}{2}$ more cups

Required

How many cups did Ian drink altogether

This question can be solved by adding the size of water he drank during the hike and when he got home

i.e.

$Total = 3\ pints + 1\frac{1}{2} cups$

But the answer should be in cups;

So, number of pints has to be converted to number cups

Given that 1 pint = 2 cups;

3 pints will be 3 * 2 cups

3 pints = 6 cups;

So,

$Total = 3\ pints + 1\frac{1}{2} cups$

$Total = 6\ cups + 1\frac{1}{2} cups$

$Total = 7\frac{1}{2} cups$

Altogether, he drank $7\frac{1}{2} cups$ of water

A tree cast a shadow that is 20 feet long. Frank is 6 feet tall, and while standing next to the tree he cast a shadow that is 4

baherus [9]

A. So we know that a 6 foot figure casts a shadow 4 feet long. 4 foot shadow x 5 = a 20 foot shadow. So this means we take 6 x 5 = 30, and the tree is 30 feet tall.
B. 30 - 6 = 24 feet taller than Frank

I have a square graph, but I would like to make the graph larger.

fenix001 [56]

FORMULA:

Area of ⬜ = (side)²

ANSWER:

We are given new side of square i.e, 2s + 3.

So, Area = (2s + 3)²

(2s)² + (3)² + 2 × 2s × 3
4s² + 9 + 12s

Hence, The area of the new graph is a perfect square trinomial: __4__s² + __12__s +__9__.
