Answer:
12.808 meter is the length should Rickey use for the mural.
Step-by-step explanation:
Area of the mural = A = 
Length of the mural = l
Width of the mural = w
l = 5 + 2w
Area of the rectangle = l × w



Solving above equation with the help of Completing squares method:






w = 3.904 m (accept)
w = -6.404 m (reject)
l = (5 + 2w)m = 5 + 2 × (3.904) m= 12.808 m
12.808 meter is the length should Rickey use for the mural.
Answer:
Step-by-step explanation:
y - 11 = 6(x - 3)
y - 11 = 6x - 18
y = 6x - 7
Hi there
The formula of compounded continuously is
A=pe^rt
A future value?
P present value 1300
E constant
R interest rate 0.042
T time 5years+9/12=5+9/12=5.75years
So
A=1,300×e^(0.042×5.75)
A=1,655.10 round your answer to get
A=1655
Good luck!
This is a distance problem so we can use distance = rate x time.
Given: the distance to the telephone is the same as the distance back from the telephone. We also know the two speeds and the total time for the trip.
But first let's convert 15 minutes into seconds: 15*60 = 900 seconds.
So: d = 5(t1) (t1 is the time he took to run to the telephone)
d = 4(t2) (t2 is the time he took to come back from the telephone
t1 + t2 = 900 or t1 = 900 - t2
Now use substitution:
5t1 = 4t2
5*(900 - t2) = 4t2
4500 - 5t2 = 4t2
4500 = 9t2
500 = t2
So therefore t1 = 400
So the distance to the telephone is 5*400 = 2000 meters
The angle x and the angle 18 degrees combine to form a right angle. The two angles add to 90 degrees
<h3>x+18 = 90</h3>
If you want to solve for x, then subtract 18 from both sides
x+18 = 90
x+18-18 = 90-18
<h3>x = 72</h3>
