An athlete jumps these four distances In the long jump competition which jump does not run to 4.7 m²
egoroff_w [7]

Answer:

3rd jump

Step-by-step explanation:

The distance jumped is given in the table attached. to get the jump that do not round up to 4.7 meters, we round each of the jump to one decimal place and then select the jump that does not round up to 4.7 meters.

Therefore rounding off gives:

1st jump: 4.746 meters = 4.7 meters to one decimal place

2nd jump: 4.680 meters = 4.7 meters to one decimal place

3rd jump: 4.647 meters = 4.6 meters to one decimal place (does not round to 4.7 meters)

4th jump = 4.733 meters = 4.7 meters to one decimal place

Please i don't understand set theory in mathematics
nordsb [41]

Set theory is the mathematical theory of well-determined collections, called sets, of objects that are called members, or elements, of the set. ... The axioms of set theory imply the existence of a set-theoretic universe so rich that all mathematical objects can be construed as sets

For example, if A = {1, 2, 3} and B = {1, 2, 3, 4, 5} then A Í B (Í means is a subset of). If A = {1, 2, 4, 8}, then n(A) = 4. This is because n(A) means the number of members in set A. The universal set is the set of all sets.

a box of powdered laundry detergent contains 5.2 ounces of detergent. It takes 0.7 ounce of detergent to clean a load of laundry
ollegr [7]
So a box has 5.2 oz
it takes 0.7 oz to clean one load

with 3 boxes (3 times 5.2) how many can be cleaned

3 times 5.2=15.6
15.6/0.7=156/7 how many loads=22 and 2/7 =22.285 loads or less than 22 loads (since you can't clean a decimal of a load)

22 Loads is the answer
