Let Rs.x and Rs.y be the cost of a knife and a spoon respectively.
From question,
x = 2y --- (1)
and,
12x + 8y = 46.08
=> 12×2y + 8y = 46.08
=> 24y + 8y = 46.08
=> 32y = 46.08
=> y = 46.08/32
=> y = 1.44
putting y = 1.44 in (1)
=> x = 2×1.44
=> x = 2.88
Therefore, cost of a knife is Rs 2.88
Hi there!
The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. (two times pi times radius times height) Using this formula, we can plug in the values and solve for the lateral area.
Plugging in the values: LA = 2 x pi x 7 x 9
Simplifying: LA = 2pi x 63
LA = 126pi yd^2
ANSWER:
The 4th option - 126pi yd^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Answer:
-12
Step-by-step explanation:
The average rate of change of a function f(x) on an interval [a, b] is defined as ...
average rate of change = ((f(b) -f(a))/(b -a)
For the given function and interval, this is ...
average rate of change = (f(1.25) -f(0.75))/(1.25 -0.75)
= (4 -10)/(0.5) = -12
The average rate of change is -12 on the interval.
__
The calculator results for f(1.25) and f(0.75) are shown in the attachment, along with the computation of the average rate of change.
Answer:
y=-4/5x-1 3/5
or you can write as
y=-4/5x-8/5
Step-by-step explanation:
m=y1-y2/x1-x2
m=0-(-4)/-2-3 input
m=4/-5 solve
m=-4/5
we will find y-intercept now
we will input the points and the slope into the equation to find b
y=-4/5x+b
0=-4/5(-2)+b input
0=8/5+b multiply
-8/5=b isolate b
-1 3/5=b make improper fraction mixed number
so the y-intercept is -1 3/5
if we plug everything in we have equation
y=-4/5x - 1 3/5
or write y-intercept as improper fraction like
y=-4/5x - 8/5
