So it only took halley a half an hour (30 minutes) to do her chores.
Answer:
Option A, 5/8 - 6/8
Step-by-step explanation:
<u>Step 1: Find a common denominator</u>
5/8 is good
3/4 -> 3*2 / 4*2 -> 6/8
<u>Step 2: Combine</u>
5/8 - 3/4 is now 5/8 - 6/8
Answer: Option A, 5/8 - 6/8
The correct answer is A. 10 bracelets
Set f(b) = b^2 - 75 = to 0 and solve for b:
b^2 = 75
b^2 = 25(3)
b = plus or minus sqrt(25[3]) = plus or minus sqrt(25)*sqrt(3) = plus or minus 5 sqrt(3).
Answer:
k=6
Step-by-step explanation:
Line partition formula
1/b(x2-x1)+x1, 1/b(y2-y1)+y1
Where b is the number partitions.
We know the x values so Subsitue 17 for x2 and 2 for x1. and we know this value must equal 7.
1/b(17-2)+2=7
1/b(15)=5
1/b=1/3
b=3
so the partition is 1/3

So let find the y coordinate

So our y coordinate is 6.
