Answer:
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
The formula for a two-dimensional
vector field will be:
F = F(x,y) = <u(x,y), v(x,y)> = u i + v j;
Where (i,j) are unit vectors in
the coordinate directions
To make all vectors parallel to the x-axis
v(x,y)=0
F(x,y) = <u(x,y),0>
To make all vectors on a horizontal line having the
same magnitude.
u(x,y) = u(y)
so
F(x,y) = <u(y),0> = u(y) i
Let's break it down quick
since (8*5) is in parenthesis, you have to do it first which would equal 40. 10*2=20*8 is 160. Since there is a negative in between that and 3*40 you must solve 3*40 first, which equals 120. Now,
160-120= 40
The answer to the question is 40.
Converting from meters to centimeters uses a negative exponent because a centimeter is a smaller unit of measurement than a meter. A centimeter is one hundredth of a meter.
Converting from meters to millimeters uses a positive exponent because a meter is bigger than a millimeter. One meter is equal to one thousand millimeters.
<h3>Further Explanation</h3>
Negative Exponents
Negative exponents are used to show division. A number with a negative exponent should be divided by itself for the amount of times the exponent indicates. For example is 10 / 10 / 10 which equals .001.
Another example = 0.125
Positive Exponents
Positive exponents are used to show multiplication. A number with a positive exponent should be multiplied by itself for the amount of times the exponent indicates. For example is 10 x 10 x 10 which equals 1,000.
Another example = 8
Meters
A meter is a metric unit of measurement.
1 m = 100 cm
1 m = 1,000 mm
