Answer:
You need 3/10 buckets of nuts to fill the barrel.
Step-by-step explanation:
We know that 1/5 of a bucket of nuts, fills 2/3 of the barrel.
Then how much we need to fill the other 1/3 of the barrel?
1/3 = (2/3)/2
Then we need half of 1/5 buckets of nuts, this is:
(1/5)/2 = 1/10 buckets of nuts.
Then we need in total:
1/5 + 1/10 buckets of nuts.
we can multiply and divide the left fraction by 2, to get:
(2/2)*(1/5) + 1/10 = 2/10 + 1/10 = 3/10
You need 3/10 buckets of nuts to fill the barrel.
Answer: If the line in the circle goes halfway through it is the radius but, if it goes all the way it is the diameter.
Step-by-step explanation:
B.
1. The line goes through halfway = radius(r)
2. Take (r)= 3mm and use the formula C= 2 x Pie x r (3)
Type into calculator
It is the same for b, d, and e
C.
1. the line goes all the way through = diameter (d)
2. Take (d)= 15mm and use in the diameter formula C= Pie x d (15mm)
Note you do not times the diameter x2 because it goes ALL the way through the circle.
Unlike the radius that goes halfway through so you need to x2 or double it to get the full circumference
Hope This Helps ( also make sure to put the units in your answer mm,cc,etc)
Answer: (C) 7x + 11x =90
Step-by-step explanation: The angle is a right angle which means that it equals 90 degrees so both angles in the right angle will add up to 90 degrees.
Her first step should be to factor the equation by splitting down the middle
Hope this helps!
Sorry this took a while but it should be the last option for it to be correct.
