Perimeter = 2(length + width)
59 = 2(14+x)
59 = 28 + 2x
31 = 2x
15.5 = x
Width = 15.5
Answer:
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Step-by-step explanation:
f(x) = -3x² +30x - 71
f(x) = -3(x² +-10x) - 71
f(x) = -3(x² +-10x+5^2-5^2) - 71
f(x) = -3(x² +-10x+5^2) -3(-5^2) - 71
f(x) = -3(x² +-10x+5^2) + 4
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
The question is asking us to find the decimal equivalent of
%
Percent means out of 100.
=6.77777.
6.777%= 6.777÷100
=0.068.(Rounded to nearest thousandths)
Option B is the right answer.
Angle n and angle l have the same degree so set them equal to eachother
7x+8=9x-8
-7x both sides
8=2x-8
+8 both sides
16=2x
÷2 both sides
x=8
solve for angle l
9 (8)-8
72-8=64°
solve for angle OML
90+64+OML=180
154+OML=180
-154 BOTH SIDES
OML=26°
If 3 people take the day off, they will need (9 + 3/5) hours to mow the lawn. The correct option is B.
<h3>
How many hours will it take to mow the lawn?</h3>
Let's say that each person works at a rate R.
8 people can mow the lawn in 6 hours, then we can write:
(8*R)*6 hours = 1 lawn.
Solving for R:
R = (1/48 lawns per hour).
If 3 people take the day off, then the lawn is mowed by 5 people in a time T, then we need to solve:
(5*R)*T = 1 lawn.
Replacing the value of R:
(5/48 lawns per hour)*T = 1 lawn.
Then we have:
T = (48/5) hours.
We can rewrite that as:
T = (45/5 + 3/5) hours
T = 9 + 3/5 hours.
Then we conclude that the correct option is B.
