Orders are a, b, c, lets write equations to represent the problem's info:
a + b = 150
b + c = 100
a + c = 150
so we have 3 unknowns and 3 equations, so we can solve.
<span>Use the first equation:
a + b = 150
</span>a = 150 - b
and substitute in the 3rd:
<span>a + c = 150
</span>150 - b + c = 150
then
b = c
and we can substitute that in the original equation:
<span>b + c = 100
</span>2b = 100
b = 50
c = 50
and substitute in the first equation:
<span>a + b = 150
</span>a = 150 - b = 150 - 50
a = 100
then a = 100, b = c = 50
Answer:
1-(r÷7) or r÷7-1
Step-by-step explanation: Quotient is the result of a division problem.
Answer:
Step-by-step explanation:
The formula to use for this is
For us,
A(t) = 4300
P = 3800
n = 4
t = 2
r = ?
Let's fill in what we have then:
which simplifies a tiny bit to
The first thing to do is to divide both sides by 3800 to get
Now take the 8th root of both sides (on your calculator, of course!) to get
Now subtract 1 from both sides to get
And multiply both sides by 4 to get
.0622869598 = r
Multiply by 100 to get the rate as a percentage. It rounds to
r = 6.23%
The correct answer for the completion exercise shown above is: "Rectangle".
Then, the complete sentece is: <span>The only way to circumscribe a circle around a parallelogram is to make the parallelogram a rectangle.
The explanation is shown below:
By definition, a parallelogram is a four sided polygon (or a quadrilateral). Therefore, to circumsbribe a circle around this figure, all the vertexes must lie on the circle and it must have four angles of 90 degrees. So, it must be a rectangle. </span>
