Dawn and emily each had the same length of ribbon
Dawn and Emily have equal lengths of ribbon. Explanation Since the problem states that Dawn and Emily each had the same length of ribbon, their ribbon lengths are equal. If we denote the common length as L, then Dawn’s length = L and Emily’s length = L. Without a numeric value for L, we cannot […]
Identify the equivalent expression for each of the expressions below
Please provide the expressions to identify their equivalent expressions. Explanation Equivalence means two expressions simplify to the same value for all values of the variables within their domain. To identify an equivalent form, you transform one expression using algebraic rules, factoring, expanding, combining like terms, and applying identities (e.g., trigonometric or logarithmic identities) until it […]
Dawn and emily each had the same length of ribbon
They had the same length of ribbon, but the exact length cannot be determined from the information given. Explanation Let L denote the length of ribbon each person has. The statement “Dawn and Emily each had the same length of ribbon” implies Dawn’s length equals Emily’s length, so Dawn’s length = Emily’s length = L. […]

You roll an even number on a number cube.
The probability of rolling an even number on a standard six-sided die is 1/2 (50%). Explanation On a standard number cube (die), the even faces are 2, 4, and 6. There are 3 favorable outcomes out of 6 total possible outcomes, so the probability is P(even) = 3/6 = 1/2 = 50%. This means that, […]
Zinc nitrate crystals are strongly heated
Strong heating of zinc nitrate crystals causes dehydration followed by decomposition to zinc oxide with release of nitrogen dioxide and oxygen. Explanation Zinc nitrate commonly exists as hydrates such as Zn(NO3)2·6H2O. When heated, the water of crystallization is driven off first, yielding anhydrous Zn(NO3)2. With further heating, the nitrate decomposes to zinc oxide and gaseous […]
