Saul makes green paint by mixing blue paint and yellow paint.

Mamont248 [21]

Answer:

12 gallons of yellow paint

4 gallons of blue paint

Step-by-step explanation:

saul’s paint ratio is 3b to 1y which makes 4ounces of paint total (3b+1y=4)

So if you want 16 gallons of paint total using the same ratio of colors then you need to figure out how many of the recipe you will need to put in by dividing

16/4=4 so 4 times the original recipe

Now multiply the original paint numbers by 4 since you will do the ratio 4 times

3y*4= 12 gallons of yellow paint and

1b*4= 4 gallons of blue paint

Hope this helps! :)

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate

Veronika [31]

It takes 8.35 hours for the size of the sample to double

Step-by-step explanation:

The form of the continuous exponential growth model is

$A=Pe^{rt}$ , where

A is the new value
P is the initial value
r is the rate of growth or decay in decimal
t is the time

∵ The growth rate is 8.3%

∴ r = 8.3 ÷ 100 = 0.083

∵ The size of the sample will doubled in t hours

∴ A = 2 P

Use the formula of the contentious exponential growth above

∵ $2P=Pe^{0.083t}$

- Divide both sides by P

∴ $2=e^{0.083t}$

- Insert ㏑ in both sides

∴ $ln(2)=ln(e^{0.083t})$

- Remember $ln(e^{n})=n$ because ㏑(e) = 1

∴ $ln(2)=0.083t$

- Divide both sides by 0.083

∴ $\frac{ln(2)}{0.083}=t$

∴ t = 8.35 hours to the nearest hundredth

It takes 8.35 hours for the size of the sample to double

Name the intersection of planes RTW and RQW. I have no idea how to do this.. help please???

Helga [31]

In general, the intersection of two planes is the line passing through the points shared by the plane.

In this case, it would be line RW.
