Answer:
0.08, or 8%
Step-by-step explanation:
The appropriate formula is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
We want to calculate r when i, p and t are known.
i
Solving i = p*r*t for r, we get r = ------------
p*t
The interest rate in this case is
$1600
r = ---------------- = 0.08, or 8%
$5000*4
Answer:
$435
Step-by-step explanation:
a. 40m+35
b. 40(10)+35
=400+35
= $435
hope it's correct
The measures of 2 vertical angles are always equal, so we have:
7x+182=9x+192.
Rearranging, we have 182-192=9x-7x, which simplifies to -12=2x.
Thus, x=-6.
This means that the angles are:
i) 7x+182=7(-6)+182=182-42= 140(degrees).
ii) <span>9x+194=9(-6)+194=194-54=140 (degrees, as expected.)
Answer: x=-6</span>
Answer:
Part 1) The diameter is
Part 2) The radius is
Part 3) The length of an arc is equal to
Step-by-step explanation:
Part 1) Find the diameter
we know that the circumference of a circle is equal to
where
D is the diameter
we have
assume
substitute and solve for D
Part 2) Find the radius
we know that
The radius is half the diameter
so
substitute
Part 3) Find the length of an arc of 190 degrees
we know that
The circumference of the circle subtends a central angle of 360 degrees
so
using proportion
