Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
Answer:
96
Step-by-step explanation:
if u times 24x4=96
Percentage increase/decrease is given by (the difference ÷ original value) × 100
The decrease in value is 16500 - 14000 = 2500
The percentage decrease = (2500÷16500) × 100 = 15.2%
It’s 100°! I cause 75+75 = 150 and if the circle is 350 then 150-350 = 200 and 200÷2 is 100
Answer:
It means that the both sides of the expression in the given equation must be/are congruent.
Hope this helps!
