The major and minor axes of an ellipse are 25 inches and 4 inches in length, respectively. What is the area of the ellipse? Round to the nearest tenth

The answer to your question is Area = 78.5 in²  

Step-by-step explanation:

Data

Major axes = 25 in

Minor axes = 4 in

Area = ?

Formula

Area = a  x b x π

Process

1.- Calculate a

a = Major axes / 2

  = 25 / 2

  = 12.5 in

2.- Calculate b

b = Minor axes / 2

   = 4 /2

   = 2 in

3.- Substitution

Area = 12.5 x 2 x 3.14

4.- Result

Area = 78.5 in²        

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
