Answer:

Step-by-step explanation:
Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make
flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make
flowers in an hour.
The groups decided to work together. They can make
together in an hour and it takes them
hours. Group B took a break for 1 hour and 40 minutes (
hour), then Group B works
hours.
Thus,

Volume units quarts to gallons (fluid and dry) conversion factor is 0.25 (quart is 1/4 of an gallon). To find out how many gallons in quarts, multiply by the factor, or simply use the converter below.
1 Quart = 0.25 (1/4) Gallon [US, UK, Fluid or Dry]
Quart and gallon are imperial and US customary volume measurement units. In US customary system, both units have different volume capacity for dry and fluid measurements but in imperial (UK), the volume is the same for both fluid and dry measurement.
Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
V=2*pi*r*2*h
V=(4*pi*r)*h
V/(4*pi*r)=h
so h=V/(4*pi*r)
