Answer:
l=15 m
Step-by-step explanation:
Given that a blueprint of a plot of land has a scale of cm to m.
i.e. if it measures 1 cm in blue print actual dimension is 1 m.
The length of land measures 15 cm on the blueprint.
For 1 cm actual length = 1 m
So for 15 cm actual length = 15 m
So we get
if l represents the length of the actual piece of land,
l=15 m
Answer:
Step-by-step explanation:
Hello, it means that the number is
57 * 37 + 29 = 2138
Thank you
If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
Answer:
<u><em>What is the importance of polynomial functions?</em></u>
<u><em>
</em></u>Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.

<u><em>How these real-life applications improve or contribute to the value of life?</em></u>
Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.
B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
