At a construction job for a theater, there are 30 painters. Of these painters, 24 of them are painting the interior of the theater. What percent of these painters are painting the interior?
Answer:
80 percent of the workers are painting the interior
Step-by-step explanation:
24 of 30 is 80 percent
Answer:
80%
Step-by-step explanation:
Let's do this
So they are asking "What percent of these painters are painting the interior?"
So use this formula-
Second number mentioned/First number mentioned*100
As it says "What percent of these painters are painting the interior?" , the interior number is the second number and the total painters is the first number mentioned.
So let's put the values-
24/30*100=80%
The answer is 80%.
Melanie was mixing red and white paint to make pink paint. The tables below show the ratios of three different shades of pink she made. Which one is the lightest shade of pink?
Answer:
B
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
For what value of b, would the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions?
b = ____
When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.
When does a system of linear equation have no solution?When both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.
If they are coincident, then there will have infinite solution since in that case, they will have infinite points in common.
Thus, if two lines are not in any of above case, they intersect at single point and in that case, the considered system of equation has unique single solution.
The equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.
When b = 23 ,
3/4(12x−9)+b/4=5−3(2−3x)
When the value of b is 23 then the equation 3/4(12x−9)+b/4=5−3(2−3x) have infinitely many solutions.

A pipe is draining water from a tank. The table below shows the time in minutes and the number of gallons remaining in the tank. 5 mins drained 300 gallons, 10 mins drained 260 gallons, 15 mins drained 220 gallons, 20 mins drained 180 gallons, and 25 mins drained 140 gallons. Based off the pattern/rate, how much water would be drained in a half an hour?
Answer: 3,600 gallons in an hour and a half
Step-by-step explanation:
Because every 5 minutes it drained 40 gallons so you’d have to do 40 times 90 because there is 90 minutes in a half an hour and that gives u 3,600 gallons
