The mechanical advantage is the ratio of the radii: 5/0.5=10.
Answer:
x = 72
Step-by-step explanation:
By exterior angle theorem:
x° + (x + 10)° = 154°
(x + 10 + x) ° = 154°
(2x + 10)° = 154°
2x + 10 = 154
2x = 154 - 10
2x = 144
x = 144/2
x = 72
Answer:
Farmer Janet can plant carrots more quickly.
Step-by-step explanation:
If we added 15 more minutes to Farmer Janet's time to equal the same amount as her daughter. We would also have to double the amount of carrots she can plant which totals out to 18 carrots which is 1 more carrot more than her daughter. I hope this helps:)
Answer:
X = 13/2 or X =7/2
Step-by-step explanation:
x^2-5x+4
Where a =1, b= -5, c= 4
X = -b( +,-) √b^2-4ac/ 2a
X = -(-5)( +,-)√(-5)^2-4(1)(4)
/ 2(1)
X= 5 ( +,-)√25-16
/2
X= 5 ( +,-)√9/2
X = 5+3/2 or X =5 -3/2
X = 13/2 or X =7/2
It has got two solutions
