The perimeter is 20 feet, half the perimeter Would be 10 feet.
Need 2 numbers when added together equal 10 and when multiplied together equal the area of 21.
3 and 7 The pond is 3 feet by 7 feet.
Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
Answer:
a) y = 117
b) z = 27
Step-by-step explanation:
I haven't done these in a while, but here is my try...
a)
y + 63 = 180
y = 117
b)
( 5z - 18 ) + 63 = 180
5z - 18 + 63 = 180
5z - 18 = 117
5z = 135
z = 27
Hopefully this helps!

Answer:
1/2
Step-by-step explanation:
● 1/4 + 4(1/2 - 3/4 )^2
To make it easier convert the fractions to decimal numbers.
● 1/4 = 0.25
● 1/2 = 0.5
● 3/4 = 0.75
So the expression will be:
● 0.25 + 4(0.5 - 0.75)^2
Calculte first 0.5-0.75 (0.5-0.75= -0.25)
● 0.25 + 4 × (-0.25)^2
-0.25^2 is the same as 0.25^2
● 0.25 + 4 × (0.25)^2
0.25^2 is 0.0625
● 0.25 + 4×0.0625
Multiplication has the priority (4 ×0.0625) wich is 0.25
● 0.25 + 0.25
● 0.5
0.5 is 1/2
So the answer 1/2
Answer:
B. The approximate length of EF is 4.47 units, and the approximate perimeter of triangle EFG is 12.94 units.
Step-by-step explanation:
First step is to determine the length of EF, since that will give us 2 sides of the triangle (since EG = EF).
From the diagram, we can easily make a rectangle triangle by dropping a vertical line from vertex E, let's name Z the meeting point of that line with the segment GF. Then we have a rectangle triangle EZF with a height of 4 and a base of 2, of which EF is the hypotenuse. So...
EF² = 4² + 2² = 16 + 4 = 20
EF = √20 = 4.47
Now that we have EF, we also have EG:
EF = 4.47
EG = 4.47
GF = 4 (visible on the graph)
Perimeter = 4.47 + 4.47 + 4 = 12.94 units.
