Answer:
x = 5 units.
Step-by-step explanation:
In a parallelogram. diagonals bisect each other.
This means 
.
.
Therefore, the length of x = 5 units.
Set variables for the quantities we want to find. Let x = number of applesLet y = number of oranges Next, we use these variables to write equations that describes the whole story. Since the total price is $7.75 and each type of fruit has their own price, we can say 0.40x + 0.35y = 7.55 The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
1) 180 square cm
Answer:
2) 41 cubic cm
Step-by-step explanation:
1)
Area of pool = 12 * 15 = 180 square cm
2) Volume of water = 1/3 * Volume of pool
= 1/3 *123
= 41 cubic cm
Answer: divide 150-0.20=149.8
Step-by-step explanation:
Given
centre of circle O(3,2)=O(x0,y0)
point on circle P(6,-2)
Standard equation of circle:
(x-x0)^2+(y-y0)^2=r^2
r=radius of circle
= (distance OP)
= sqrt((6-3)^2+(-2-2)^2)
=sqrt(3^2+(-4)^2)
=sqrt(25)
=>
r^2=(sqrt(25))^2=25
Equation of circle
(x-x0)^2+(y-y0)^2=r^2
(x-3)^2+(y-2)^2=25 ............... standard equation of circle
