A farmer plants corn in of his field. He plants white corn in of the corn section of his field. This situation is shown in the model. What fraction of the

whole field is planted with white corn?

3/20

Question:

A farmer plants corn in 1/4 of his field. He plants white corn in 3/5 of the corn

section of his field. This situation is shown in the model. What fraction of the whole field is planted with white corn

Step-by-step explanation:

Portion of the field planted with corn = 1/4

Total corn planted = 1/4 of field

Portion of the corn section planted with white corn = 3/5

Total white corn planted = 3/5 of corn section

We need to find the portion of the total field planted with white corn

The fraction of the whole field planted with white corn would be the product of the fraction of Total corn planted and fraction of Total white corn planted

= 1/4 × 3/5

= 3/20

The fraction of the whole field planted with white corn = 3/20

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
