Let n be the number of lbs of nuts.
Let r be the number of lbs of raisins.
9n + 3r = 60 * 5 = 300 .............(1)
n + r = 60
n = 60 - r ...............(2)
Plugging the expression for n in (2) into (1) we get:
9(60 - r) + 3r = 300
which expands to:
540 - 9r + 3r = 300 .............(3)
Simplifying and rearranging (3) we get:
-6r = -240
Therefore r, the weight of raisins = 40 lbs
and the weight of nuts is 60 - 40 = 20 lbs
x = -2
function value at x = -2 is intersection of the x value and graph
which is, 3
Hope it is clear:)
Diameter= 18cm
Radius is half of diameter
Radius=9cm
Answer: 1620
Step-by-step explanation: This is for a parallelogram you would multiple 6 base x's 4.5 height= 27 area for each diamond.
He's using 60 tiles. Multiple the area of 1 tile which is 27 by 60 wooden tiles to find the area of the parallelogram. 27 multipled by 60 tiles= 1620 inches squared
What we have here is called INTERSECTING CHORDS IN A CIRCLE.
The equation is:
10 times x = 7 times 7
10x = 49
x = 49/10
x = 4.9
