Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
Hi!
The correct answer to this <span>expression is y=9 if the equation is y-8+2=3 or y=19 if the equation is y-8</span>×2=3.
To get y=9 you need to add 2 to -8 to get -6, then you need to find the number that when subtracted by 6 equals 3 and that number is 9.
To get y=19 you need to multiply -8 by 2 to get -16, then you need to find the number that when subtracted by 16 equals 3 and that number is 19.
If it is neither of these answers then it is y-8 because you are replacing 2 with 3 in the expression.
Answer:
71
Step-by-step explanation:
(73)-2 is equivalent to 71
Nope! If they were proportional, one would be able to be reduced to the other.
It's like the (however clichéd) example of pie slices! If you cut two pies into 8 and 20 pieces, three pieces of the pie sliced into eight pieces will not be the same as seven pieces of the pie sliced into twenty!
