There are white, blue, and red boats in a marina. Two-thirds of the boats in the marina are white, five-eighths of the remaining
sammy [17]
X = total boats
2/3x are white....so the remaining boats = 1/3x
5/8 of the remaining boats are blue.....5/8 * 1/3 = 5/24x are blue

2/3 + 5/24 = 16/24 + 5/24 = 21/24 are blue and white......so 3/24 are red
3/24x = 6
x = 6 * 24/3
x = 144/3
x = 48 total boats in the marina <==

2/3(48) = 32 white
5/24(48) = 10 blue
3/24(48) = 6 red

BigorU [14]

Answer:

9

Step-by-step explanation:

Given: Subtract 9 from 10. Multiply this difference by 3, square this product.

Now, lets simplify it.

[(10-9)\times 3]^{2}

Using PEDMAS rule to solve it

First working on Parenthesis

= [(1)\times 3]^{2}

Opening the parenthesis

= [1\times 3]^{2}

= [3]^{2}

= 9

∴ Answer is 9.

Select all of the ratios that are equivalent to 1:5. 6:30 5 to 20 8 to 40
nadya68 [22]

Answer:

6:30 and 8 to 40 are equivalent to 1:5

Step-by-step explanation:

Ratios can be rewritten to fractions where you can do the butterfly method.

1/5 and 6/30 would be equivalent because 30 x 1 is 30 and 5 x 6 is 30

1/5 and 8/40 would be 40 x 1 and 5 x 8
