A sample of grape juice has a hydroxide ion concentration of 1.4 × 10-10 M. Is the grape juice more or less acidic than a sample of orange juice that has a hydronium ion concentration of 1.8 × 10-4 M? To compare the acidity of the orange juice and grape juice, compare the hydronium ion concentrations and/or pH values of the two solutions. How does the acidity of a solution vary with hydronium ion concentration and pH?
2.) lee has seven 5-dollar bills and le quarters in his pocket. How much money would he have left in his pocket if he buyes a leather jacket worth $35.20.
Triangle ABC is a right triangle. Point D is the midpoint of side AB, and point E is the midpoint of side AC. The measure of ∠ADE is 68°. Triangle ABC with segment DE. Angle ADE measures 68 degrees. The proof, with a missing reason, proves that the measure of ∠ECB is 22°. Statement Reason m∠ADE = 68° Given m∠DAE = 90° Definition of a right angle m∠AED = 22° Triangle Sum Theorem segment DE joins the midpoints of segment AB and segment AC Given segment DE is parallel to segment BC ? ∠ECB ≅ ∠AED Corresponding angles are congruent m∠ECB = 22° Substitution property Which of the following can be used to fill in the missing reason? Triangle Inequality Theorem Midsegment of a Triangle Theorem Concurrency of Medians Theorem Isosceles Triangle Theorem

The data to the right represent the cost of living for 20 states. The cost of living is a measure of the average price paid for housing, utilities, groceries, healthcare, transportation, and miscellaneous expenses. The national average cost of living is 100. The data can be used to compare a state to the national average and to other states. T Use these data to construct a frequency distribution with a first class of 85.0-94.9. Fill in the missing classes and the frequency for each class belo Cost of living Number of states 9 85.0-94.9 125.0134.9 8-8 20 (Type integers or decimals.

Evaluate the extent of the similarities between the policies of President George Washington and those of President Thomas Jefferson.
In your lab, a substance's temperature has been observed to follow the function T(x) = (x − 5)3 + 9. The turning point of the graph is where the substance changes from a liquid to a gas. Using complete sentences in your written answer, explain to your fellow scientists how to find the turning point of this function. Hint: The turning point of the graph is similar to the vertex of a quadratic function.
Sulfur compounds cause "off‑odors" in wine, so winemakers want to know the odor threshold, the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine ( g/L ). The untrained noses of consumers may be less sensitive, however. The DMS odor thresholds for 10 untrained students are given
