Answer:
%35 of them were in color
Step-by-step explanation:
Since 30 percent of the first 200 sold were in color, 200x30/100 = 60 of them were in color.
Since 20 percent of the next 300 sold were in color, 300x20/100 = 60 of them were in color.
Since 90 percent of the last 100 sold were in color, 100x90/100 = 90 of them were in color.
In total, 60 + 60 + 90 = 210 out of 600 were in color.
The percentage is: =
→ x =
= 35
Final answer:
To find the percentage of advertisements that were sold in color, divide the number of color ads by the total number of ads and multiply by 100. We get answer 35.
Explanation:
To find the percentage of advertisements that were sold in color, we need to find the number of color advertisements in each group and then calculate the percentage.
- For the first 200 ads, 30% were in color, so the number of color ads is 0.3 * 200 = 60.
- For the next 300 ads, 20% were in color, so the number of color ads is 0.2 * 300 = 60.
- For the last 100 ads, 90% were in color, so the number of color ads is 0.9 * 100 = 90.
The total number of color ads is 60 + 60 + 90 = 210. To find the percentage, we divide 210 by 600 and multiply by 100.
So, the percentage of advertisements that were in color is 35%.

Answer:
Initial temperature = 20° C
Temperature after 18 minutes = 4° C
Step-by-step explanation:
Function representing the relation in the temperature of the soda and time has been given as,
T(x) =
Here x = number of minutes since the can was placed in the cooler
For initial temperature of the soda,
x = 0,
T(0) =
= -8 + 28(1)
= 20° C
For the temperature after 18 minutes,
x = 18,
T(18) =
=
=
= 4.456 C
≈ 4° C

Answer:
208.02 m
Explanation:
When the model rocket lands, y = 0; therefore, the equation becomes
Using the quadratic formula we solve for x.
Which simplifies to give
Hence, we have the solutions
since lengths cannot be negative, we choose x = 208.02 as our answer.
Hence, the model rocket lands 208.02 m from the starting point.
