Intersection means common elements in both sets
Answer:
Step-by-step explanation:
If Daniel does 1/9 of the job in one hour
let x = Paul's rate
Paul does 1/x of the job in one hour
They both do the job in 4.95hrs
(1/9)(4.95) + (1/x)(4.95) = job completion
multiply both sides by 9x
(9x)(1/9)(4.95) + (9x)(1/x)(4.95) = 9x(1)
4.95x + 9*4.95 = 9x
4.95x + 44.55 = 9x
9x - 4.95x = 44.55
4.05x = 44.55
x = 44.55/4.05
x = 11 hours i.e time it takes for Paul to pick the 40 bushels alone
Answer:
0.12 cups
Step-by-step explanation:
What we need to get here is the proportion of cheese in each dish. This implies the ratio of cheese per dish.
Sarah used 2.5 cups for 10 people, which means 2.5/10 cups of cheese per dish. 2.5/10= 0.25
So, Sarah gave 0.25 cups of cheese to each dish.
If we make the same calculation for Aron, we have 1.6/12=0.13
Arun used 0.13 cups of cheese per dish.
For getting the difference we just need to subtract:
0.25-0.13=0.12
So, Sarah used approximately 0.12 cups of cheese per dish more then Arun.
Hello!
Looking at the image above, we can see that the two “legs” of the triangle both have a length of 7 units. Consequently, this triangle can be classified as an isosceles triangle. An isosceles triangle has two sides of equal length (in this case, KJ and KL) and two corresponding angles of equal measure (in this case, ∠J and ∠L).
∠J has a measure of 25 degrees. Consequently, with our knowledge of isosceles triangles, we can conclude that ∠L has a measure of 25 degrees as well.
I hope this helps!
