Hi there! Lily has $31.50 left.
To find our answer we first need to know the amount of money Lily spend.
Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.
Hence, Lily has $31.50 left.
Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
The correct answer is two or four
Answer:
Your answer is <em>8.06</em>.
Step-by-step explanation:
Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:
a² + b² = c²
Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.
a is going to be your smallest leg, so in this case a = 4.
b is going to be your longest leg, so it is b = 7.
Now, you don't know what c yet is so you simply write it as:
4² + 7² = c²
Do the exponents.
16 + 49 = c²
Add.
65 = c²
Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.
√65 = √c2
Once you do that, you have your answer!
<u>8.0622577483 = c</u>
Now just simplify and you're done :)
<u>8.06</u>

Might sound hard now but you'll get the hang of it.
Think about it. The area (the two dimensional version of volume) of a two dimensional shape, like a square, can be 2 feet by two feet. Multiply these together, and you get 4 feet^2, or four feet squared, This is because in order to get the volume, you multiply the base times the height, one side by the other. You make the feet "feet squared" because you are also multiplying the measurements together, too. In three dimensional shapes though, you have three different ways to go. You have the base, the height and the width beyond it. So you multiply them together and get 8 feet^3 or 8 feet cubed (you multiply three measurements together).
