The formula for the circumference of a circle = 2 x radius x pi
The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
Answer:
Since them taken same time so the fraction is 1/1
180^2 + 235^2 = (cliff base to point on bridge)^2
32400 + 55225 = 87625
so cliff base to point on bridge = sqrt of 87625.
Then notice 87625 + d^2 = (x+180)^2
since x^2 +235^2 = d^2,
substitute (x^2 + 235^2) for d^2, like this:
87625 + x^2 + 235^2 = (x+180)^2
87625 + x^2 + 55225 = x^2 + 360x + 32400
87625 + 55225 - 32400 = x^2 - x^2 +360x
360x = 110450
x = about 306.8 feet
h = x+180, so h = 486.8 feet
Remember d^2 = x^2 + 235^2, so
d^2 = 306.8^2 + 235^2
d^2 = 149354.6489
d = about 386.46 feet
Let
x-------> the number of fiction books
y-------> the number of nonfiction books.
we know that
-----> equation 
-----> equation 
Add equation and equation
<u>find the value of y</u>
therefore
<u>the answer is</u>
Part a) the number of fiction books is 
Part b) the number of nonfiction books is 
Answer:
option c
Step-by-step explanation:
first, find the y-intercept:
the y-intercept is the point where the line intersects at the y-axis, in this case, at 3.
therefore, we can rule out all options except c, sincee the y-intercept is 3
hope this helps :)
