Working together they would fill two pools in 120 minutes so therefore they would fill one pool in 60 minutes

Answer:

It will take 22.5 minutes the pool with the two hoses.

Step-by-step explanation:

In this case we have to propose equations that could describe the filling of pool by the small and large hose, then sum them and find the time of fill with both:

Small hose: Volume=\frac{Volume}{90} *Time

Large hose: Volume=\frac{Volume}{30} *Time

Where Volumen is the total volume of the pool and Time is the total time of fill using the two hoses, now adding them:

Volume=\frac{Volume}{90} *Time+\frac{Volume}{30} *Time

We can clear the time:

Volume=\frac{3*Volume*Time+Volume*Time}{90}

Volume=\frac{4*Volume*Time}{90}

Time=\frac{90}{4}

Time=22.5

It will take 22.5 minutes the pool with the two hoses.

A spinner is evenly divided into eight sections: three are red, three are white and two are green. If the spinner is spun twice,
Stolb23 [73]

Answer:

11/32

Step-by-step explanation:

Given that:

Red section (R) = 3 ; white section (W) = 3 ; green section (G) = 2

Total Number of sections = 8

Probability of getting the same color on two spins :

Probability = (required outcome / Total possible outcomes)

Either P(RR) or P(WW) or P(GG)

(3/8 * 3/8) + (3/8 * 3/8) + (2/8 * 2/8)

9/64 + 9/64 + 4/64

(9 + 9 + 4) / 64

22 / 64

= 11/32
