Answer:

approx 1/4 inch of snow in 1 hour

Step-by-step explanation:

Janine wants a necklace 45 beads long 
seraphim [82]
If there are 45 beads, with a ratio of 1:4
Then,
\frac{45}{5}=9
Then if \frac{1}{4}=\frac{9}{x}
Then x=9*4
Therefore, x=36
Meaning, there would be a ratio of 36 beads to 9 beads

What are the x and y-intercepts of the line described by the equation?<br> -6x + 3y = 18.9
-BARSIC- [3]

Answer:

x-intercept - x = 1/2y - 3.15

y-intercept - y = 2x + 6.3

Step-by-step explanation:

For x,

-6x + 3y = 18.9

-6x = -3y + 18.9

x = -3y/-6 + 18.9/-6

x = 1/2y - 3.15

For y,

-6x + 3y = 18.9

3y = 6x + 18.9

y = 6x/3 + 18.9/3

y = 2x + 6.3

If LW = 5x + 2 and LJ = 11x + 2 in the parallelogram below. Find LW.
WITCHER [35]

Answer:

A. 12

Step-by-step explanation:

Recall: one of the properties of a parallelogram is that the diagonals bisect each other. This means that:

LJ = 2(LW)

11x + 2 = 2(5x + 2)

11x + 2 = 10x + 4

11x + 2 - 2 = 10x + 4 - 2

11x = 10x + 2

11x - 10x = 10x + 2 - 10x

x = 2

✅LW = 5x + 2

Plug in the value of x

LW = 5(2) + 2

LW = 10 + 2 = 12
