Answer:
OB. the assets used to secure a loan
Step-by-step explanation:
You use collateral to decrease the risk for the bank. It can be like a car, or house. If you don't pay them back, they take the car or house.
Can:
The formula for the volume of a cylinder is V = πr²h. So h = 3d = 3(2.5)
V = π1.25²(3(2.5)) = π1.25²(7.5) = 36.816 in.³
Tennis balls:
The formula for the volume of a sphere is V = (4/3)πr³.
V(3 tennis balls) = (4/3)πr³(3) = (4/3)π1.25³(3) = 8.181(3) = 24.544 in.³

Air inside the can:
V (can) - V (3 tennis balls) = </span>36.816 - 24.544 = 12.272 in.³ of air<span>

Answer:
Step-by-step explanation:
First, you need to get one like term in each equation the same in order to eliminate. To do less damage to the equation, we'll use the x terms.
To get the x terms the same, multiply both <em>equations</em> by the opposite x term:
Simplify by multiplying. Use the distributive property for the left side (remember, two negatives make a positive and a negative multiplied by a positive will always be negative):
Now subtract all like terms. The x terms cancel out:
Now solve the new equation for y. Isolate the variable by using inverse operations. The term can be seen as -29×y. In order to isolate the variable, use division (opposite of multiplication). Divide both sides by 29:
Make the variable positive. Multiply both sides by -1:
The value of y is -2. Insert this value into either original equation:
Solve for x. Simplify multiplication:
Use inverse operations to get like terms on the same side of the equation. Add 10 to both sides (addition is the opposite of subtraction) to cancel out the -10 on the left:
Isolate the variable using inverse operations. The x term can be seen as 2×<em>x</em>. Division is the opposite of multiplication, so divide both sides by 2:
The value of x is -3. Therefore, the solution to the system is:

Answer:
40 cm²
Step-by-step explanation:
A = 2(lw + lh + wh)
= 2(4×2 + 4×2 + 2×2)
= 2(8 + 8 + 4)
= 2×20
= 40 cm²
