Answer:

1/16

Step-by-step explanation:

1L = 1000 ml

2L = 2000mL

The ratio is 125/2000

Check to see if 2000 / 125 is a whole number

2000

125

And it is. The answer is 16

125/2000 = 1/16

Find the rectangular coordinates of the point with the polar coordinates (1, 1 divided by 2 pi )

Drupady [299]

Answer:

(x, y) = (0, 1)

Step-by-step explanation:

For polar coordinates (r, θ), the corresponding rectangular coordinates are ...

(x, y) = (r·cos(θ), r·sin(θ))

For r=1 and θ=π/2, the rectangular coordinates are ...

(x, y) = (1·cos(π/2), 1·sin(π/2))

(x, y) = (0, 1)

Which ordered pair is not a solution of y = -3x + 4

lakkis [162]

Test
remember, (x,y)

A.
10=-3(-2)+4
10=6+4
10=10
yep, this is a soltuion

B.
5=-3(3)+4
5=-9+4
5=-5
false, not a solution

C.
4=-3(-2)+4
4=6+4
4=10
nope, not a solution

D.
1=-3(1)+4
1=-3+4
1=1
true

hmm, I think if B was (3,-5) then C is the only one

C is the answer

Please explain the steps to answer this<br> 2|6y-4|-3=7

dem82 [27]

First you need to do the distributive property
2|6y-4|-3=7
12y +8 -3 =7 then you combine like terms
12y + 5 =7 then you subtract 5 from 7
12y=2 then divide by 12
y=0.17 or 1/6 <--- that's your answer

The sum of one half and four times a number is equal to five sixths subtracted from five times the number. Find the number.

MakcuM [25]

The sum (addition) of one-half ( $\frac{1}{2}$ ) and four (4) times (multiplication) a number (n) is equal to (=) five-sixths ( $\frac{5}{6}$ ) subtracted from (subtraction) five (5) times (multiplication) the same number (n).

$\frac{1}{2}$ + 4n = 5n - <span> $\frac{5}{6}$ Multiply both sides by 6
</span> $\frac{6}{2}$ + 4n = 5n - 5 Simplify the fraction
3 + 4n = 5n - 5 Subtract 5n from both sides
3 - n = -5 Subtract 3 from both sides
-n = -8 Divide both sides by -1
n = 8
