Answer:
Step-by-step explanation:
item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm
You did not state the diameter or radius of the window
so, i will use 90cm as the diameter of the window
First, I'd calculate the half circumference of the window.
The formula for circumference is 
,
Half of it would just be 
Since our diameter is 90 cm, our radius is 45 cm.
Circumference =
circumference is also the same with perimeter
<h3>so, the answer is 141.37cm</h3><h3>to nearest tenth = 141.4cm</h3>
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point form:
(3,2), (3-2), (-3,2), (-3,-2)
Equation Form:
x = 3, y = 2.
x = 3, y = -2.
x = -3, y = 2.
x = -3, y = -2.

Answer:
70 m/s
Step-by-step explanation:
speed = √( g x depth ); where g = 9.8m/s²
given depth = 500m
equation becomes:
speed = √( g x depth )
= √( 9.8 x 500 )
= √( 9.8 x 500 )
=√4900
=70 m/s
Answer:
y+x=31, 150x+225y=5100.
y=-x+31
150x+225(-x+31)=5100
-75x=-1875
