What is the length of arc S shown below?
2 answers:
Answer:
s = 2
Step-by-step explanation:
The length of the arc s is calculated using
s = circumference × fraction of circle
= 2πr × ( cancel 2π )
= 5 × 0.4 = 2
Answer:
Length of arc S = 2 units
Step-by-step explanation:
Circumference of the circle = 2πr
Here r = radius of the circle
Now length of the intercepted arc by the sector will be
S = Length of Circumference ×
S = [Angle inscribed by the sector is 0.4 radians]
= 0.4r
= 5 × 0.4
= 2.0 units
Therefore, length of arc S is 2 units.

Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
Given:
2x + 6y = 12
where
x = number of pounds of granola y = number of pounds of walnuts
The correct solution to the problem
x = 3 pounds
2x + 6y = 12
2(3) + 6y = 12
6 + 6y = 12
Subtract 6 from both sides
6 + 6y - 6 = 12 - 6
6y = 6
Divide both sides by 6
y = 6/6
= 1
y = 1 pound
Tomas added 6 to both sides of the equation instead of subtracting 6.
