150 pounds divided into 4:1 ratio means that there are 4+1 = 5 portions.
one quantity is 4 times the amount of the other quantity.
150 can be divided into 5 portions,
therefore 1 portion is =150/5 = 30
First quantity is 4 times the amount of one portion = 4*30 = 120
and other portion is 30
therefore quantities are divided as 120:30
Answer:
(x + 1)² + (y - 4)² = 25
Step-by-step explanation:
The general equation for a circle is given by the formula;
x² + y² + 2hx + 2ky + c = 0 ......equation 1.
Where the center is C(-h, -k)
Also, the standard form of the equation of a circle is;
(x - h)² + (y - k)² = r² ......equation 2.
Where;
h and k represents the coordinates of the centre.
r represents the radius of the circle.
Given the following data;
h = -1
k = 4
r = 5
Substituting into eqn 2, we have;
(x - {-1})² + (y - 4)² = 5²
Simplifying further, we have;
(x + 1)² + (y - 4)² = 25
400+200 or add 368+231= 599 and you round your answer, woulb be 600
1.) Plug x and y to the formula:
4(2) + 1/3(3)^2
2.) Simplify
8 + 1/3(9)
= 8 + 3
= 11
Hope this helped!!!
