A24000 gallon of pool is being filled at the rate of 40 gallons per minute at this rate how many minutes will it take to fill up this pool a.450 b.560 c.600 d.150

Option no C 600 minutes

Step-by-step explanation:

Given:

gallons of pool = 24000 gallon

Rate at which it is filled = 40 gallons per minute

To find :

Time taken to fill the pool=?

Solution:

We know that rate is the time in which a thing is being done at per minute or per hour or per second. In our question it is given that the rate is 40 gallons per minute which means that 40 gallons are filled in one minute

Now

In one minute = 40 gallons filled

Total pool size = 24000 gallons

Total time taken =

Putting in the values

Total time taken =

Total time taken = 600 minutes

So the answer is option c which is 600 minutes

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
