Suppose there's 0.01895 ml of propellant in one milliliter of spray paint. What's the amount of propellant rounded to the neares
ololo11 [35]

Answer:

The amount of propellant  is 52.770 ml of spray paint

Step-by-step explanation:

We are given

0.01895 ml of propellant in one milliliter of spray paint

so,

0.01895 ml of propellant = 1 milliliter of spray paint

We can divide both sides by 0.01895

\frac{0.01895}{0.01895} ml of propellant = \frac{1}{0.01895} ml of spray paint

1 ml of propellant = \frac{1}{0.01895} ml of spray paint

now, we can divide right side

and we get

1 ml of propellant = 52.770 ml of spray paint

The amount of propellant  is 52.770 ml of spray paint

Tara is graphing the equation 4x + 2y = 10. Which of these shows the correct equation in slope-intercept form, slope, and y-inte
Nesterboy [21]

Answer:

y = -2x + 5

slope = -2

y intercept = 5

Step-by-step explanation:

Slope intercept form of equation of line is given by y = mx + c

where m is the slope of line

c is the y intercept i.e point where given line intersect y axis.

________________________________________________

given equation 4x + 2y = 10

we have to re-write this equation in form y = mx + c

4x + 2y = 10

subtraction 4x from LHS and RHS

4x + 2y - 4x= 10 - 4x

2y = 10- 4x

we have to eliminate 2 from y for that we

divide  LHS and RHS by 2 we

2y /2 = 10/2- 4x/2

y = 5 - 2x

rearranging it in y = mx+c form

y = -2x + 5

thus, m = -2 , c = 5

URGENT please help<br><br> Find part B
lyudmila [28]

Answer:

b = 45 / 4 = 11 1 /4.

Step-by-step explanation:

We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
