Step-by-step explanation:
Monthly interest rate is %.
Each power of ten multiplies or divides the number by 10.
A number to the power of 10 multiplies the number by 10.
A number to the power of -10 divides the number by 10.
Multiplying by 10 (to the power of 10) moves the decimal point 1 place to the right.
Dividing by 10 (to the power of -10) moves the decimal point 1 place to the left.
Let's say you have
, you move the decimal place 3 places to the right.
For
move the decimal 3 places to the left.
Explanation:
ratio of two cubes: 2 : 5
Perimeter of one face of cube: 4 × side
For small cube: 4 × 2 = 8
For big cube: 4 × 5 = 20
Ratio of perimeter of one face: 8 : 20 = 2 : 5
Total surface area of cube: 6a²
For small cube: 6(2)² = 24
For big cube: 6(5)² = 150
Ratio of total surface area: 24 : 150 = 4 : 25
Volume of cube: a³
For small cube: (2)³ = 8
For big cube: (5)³ = 125
Ratio of volume: 8 : 125
ANSWER:
A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.
A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
