Since there only 3 colors you add 12/20(Red) + 6/12(Blue) and get 18/20(Combined Red and Blue)

Then you take out the Combined red and blue from the total percentage or 20/20(All 3 Combined/Full spinner)-18/20(Combined red+blue)=2/20

The answer is A.2/20

How to convert 264 yds/1 s to mi/day?
dusya [7]

Answer:

12,960\ \frac{miles}{day}

Step-by-step explanation:

we know that

1\ mile=1,760\ yards

To convert yards to miles multiply by 1/1,760

1\ hour=3,600\ seconds

1\ day=24\ hours

so

(24)3,600=86,400

1\ day=86,400\ seconds

To convert seconds to day multiply by 1/86,400

In this problem we have

264\ \frac{yd}{sec} =264\ \frac{(1/1,760)}{(1/86,400)}=264\ (\frac{86,400}{1,760})=12,960\ \frac{miles}{day}

Given p : q = 5 : 2 and q : r = 4 : 3, find the ratio of p : q : r​
yaroslaw [1]

Answer:

p : q : r = 10 : 4 : 3

Step-by-step explanation:

Expressing the ratio in fractional form

\frac{q}{r} = \frac{4}{3} ( cross- multiply )

4r = 3q ( divide both sides by 4 )

r = \frac{3}{4} q = \frac{3}{4} × 2 = \frac{3}{2}

Then

p : q : r

= 5 : 2 : \frac{3}{2} ( multiply all parts by 2 )

= 10 : 4 : 3
