Step-by-step explanation:
Answer:
length of a rectangle = l = 7 in
Step-by-step explanation:
Let,
width of a rectangle = w
length of a rectangle = l
Area = A = 77 in
A = w×l ------> (equation 1)
According to given condition:
w = l + 4 put in (equation 1)
equation 1 ⇒ A = (l + 4)×l
77 = (l + 4)×l
77 = l² + 4l
l² + 4l -77 = 0
l² + 11l - 7l -77 = 0
(l² + 11l) - (7l + 77) = 0
l(l + 11) - 7(l + 11) = 0
(l + 11) (l - 7) = 0
(l + 11) = 0 or (l - 7) =0
l = -11 or l =7
as length is always positive, therefore
length of a rectangle = l = 7 in
w = l + 4
w = 7 + 4
width of a rectangle = w = 11 in
It's annuity problem
To solve your question use the formula of the present value of annuity ordinary which is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value?
PMT yearly payments 18000
R interest rate 0.09
N time 20 years
So
Pv=18,000×((1−(1+0.09)^(−20))÷(0.09))
pv=164,313.82
Y = $0.07x+$4.95
Also, is that an umbrella academy pfp?
Hey there! I'm happy to help!
If angles are complementary, they add up to 90 degrees.
This gives us this system of equations.
J=K-18
J+K=90
We plug the value of J into the second equation to solve for K.
K-18+K=90
We combine like terms.
2K-18=90
Add 18 to both sides.
2K=108
Divide both sides by 2.
K=54
J is 18 less than K.
54-18=36
Therefore, angle J is 36 degrees and angle K is 54 degrees.
Have a wonderful day! :D
