Answer:

For #1, 8.9.

Step-by-step explanation:

I can attempt to answer it, but I can't promise anything.

Alright, so, the equation for this should be A²+B²=C²

C is usually the longer side, which for you is the side that is missing.

Let's try the first one. If what I see is right, the 2 sides are 4 and 8. A is 8 and B is 4.

That means that the equation would be 8²+4²=C²

That would be 64+16=80

The equation is now 80= c²

The opposite of "to the power of 2" is a square root. So, now you're going to find the square root of 80, which is 8.9 to the nearest tenth.

So, for the first question, the answer should be 8.9

I hope this helps you solve the rest.

The 31.31% of the $54.6 Billion was spent.

for the percentage solution

x%=(amount spent on veterinary/ total amount) *100

Calculation:

let "x" be the percent of $54.6 billion spent on veterinary and total amount spent is $17.1 billion.

putting values in above formula

x%=(17.1/54.6)*100

x%=(0.3131)*100

Greetings!

"Heather measured a swimming pool and made a scale drawing. In real life, the pool is 45 meters long. It is 65 millimeters long in the drawing. What scale did Heather use for the drawing?"...

65mm=45m
Reduce to Simpliest Form.
65/5=45/5
13mm=9m

As a Representative Fraction (scale), it would look like: (in regards to mm)
13:9000

Hope this helps.
