Answer:
$5.10
Step-by-step explanation:
The owner buys 5 panes of glass for $12.75. So to find the cost of 1, we need to divide the total cost by the amount of planes. In this case, 12.75 divided by 5. This gives you $2.55 per plane. And since he is buying 2 more, we would multiply the cost of the plane (2.55) by the amount we are buying (2). So we do 2.55 X 2 and we get $5.10
Answer:
5.) b = -2/5 (or -0.4 in decimal form)
6.) 20.5
To solve for the volume of a spherical ball, we use the formula,
V = (4<span>πr^3)/3
The given radius of 3x10^2 centimeters converts to 3 meters. Solving for the volume,
V = (4</span>π)x(3^3)/3 = 36<span>π m^3
</span>Thus, Sara is trapped in a spherical ball with a volume of 36<span>π m^3.

Mike has 10 and a half cookies (10.5). Mike wants to share these cookies with 5 friends. How many cookies does each friend get. The answer is 2.1 one (Or 2 and 1 crumb I guess lol). You place the decimal point where ever it was originally so you would place it after the 2 and before the one. It's been a while since I've done one of these problems so sorry if I'm a little rusty.
