Answer:
The length of hypotenuse is 12.5
Step-by-step explanation:
First 7.5 x 7.5 = 56.25
Then 10 x 10 = 100
Add them together 56.25 + 100 = 156.25
Then square root 156.25 and you get 12.5
We need to move the decimal so that there is only one whole number.
375,000.
To do that, we move to the left 5 spaces
3.75000
Now since we moved 5 spaces to the left it would be 3.75 * 10^5
Answer:
2) 2x = y + 13
Step-by-step explanation:
We have to translate the given information into an equation. We don't know what the numbers are yet, so let the first number be represented by the variable x and the second number be represented by the variable y.
Start by breaking the sentence apart. "2 times the first number" gives us 
. The "is" in the sentence means that equals something, bringing us to 
. Finally, it says "13 more than the second number." 13 more would mean you have to add to the second number, represented by y, so this gives us 
. Put it all together and it is 
.
