Answer:
C 12/48
Step-by-step explanation:
Original fraction:
x/y
The ratio of the numerator to the denominator is 1:4, so
x/y = 1/4
Cross multiply:
y = 4x
If three is added to the numerator and subtracted from the denominator, the new fraction reduces to one-third.
(x + 3)/(y - 3) = 1/3
Cross multiply:
3(x + 3) = 1(y - 3)
3x + 9 = y - 3
Above, we have y = 4x, so substitute 4x for y in the equation just above and solve for x.
3x + 9 = 4x - 3
12 = x
x = 12
y = 4(12) = 48
The original fraction is x/y = 12/48
Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero
only when the numerator equals 0 (the denominator cannot ever be zero):
and that happens only for x=4
Answer:
Circumference:
Area:
Step-by-step explanation:
Circumference formula: C = 2πr, where;
C = Circumference
π = (pi) 3.1416
r = radius
Replace the variables in the formula:
C =
Area formula: A = π, where;
A = Area
π = (pi) 3.1416
r = radius
Replace the variables in the formula.
Answer:
I did a data processing and uploaded for you
The final step to calculate the correlation (refer the attached image for orange, blue and green):
C = orange/sqrt(blue x green) = 0/sqrt(88.4 x 40) = 0
Unluckily, the nominator is 0, then correlation is 0, which means there is no relation between apples eaten and times sick.
Hope this helps!

Answer:
<6 , <8 , <3 are congruent to <1
Step-by-step explanation:
<6 = <1 ( being opposite Angles of parallelogram )
<8 = <6 ( being corresponding angles)
<8 = <1
<3 = <8 ( being opposite angles of parallelogram)
<3 = <1
Hope it will help :)❤
