Σελίδα 321 - The slant height of a cone is the distance between the vertex and any point in the circumference of the base. A globe or sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within, called the center.
Σελίδα 25 - Multiplying or dividing both terms of a fraction by the same number does not change its value. Changing a fraction to higher terms. 1. Explain why a fraction is expressed in smaller fractional units when it is changed to higher terms. 2. Explain why changing a fraction to higher terms does not change the value of the fraction. Change:
Σελίδα 12 - MULTIPLICATION AND DIVISION Multiplication is the process of taking one number as many times as there are units in another. The multiplicand is the number multiplied. The multiplier is the number by which we multiply. The product is the result of multiplication. The sign x indicates multiplication.
Σελίδα 321 - The slant height of a pyramid is the altitude of the triangles that bound it. A cone is a solid whose base is a circle, and whose convex surface tapers uniformly to a point called the vertex. The altitude of a pyramid, or of a cone, is the perpendicular distance from the vertex to the base.
Σελίδα 290 - Observe how the product of the extremes in each proportion compares with the product of the means. In every proportion the product of the means is equal to the product of the extremes. 1.
Σελίδα 289 - denominator Since the antecedent of a ratio may be regarded as the numerator, and the consequent as the denominator of a fraction, both terms of a ratio may be multiplied or divided by the same number without changing the value of the ratio. Find the ratio of : 3. 4. 5. 6. 10 to 5 5 to 15 8 to 2
