Answer:
The number of red circles to be added would be equal to 8 times the original amount of red circles
Step-by-step explanation:
Let
x ----> the number of red circles
y ----> the number of blue circles
Originally

----> equation A
How many more circles would need to be added to make the ratio of red to blue 3:1
Let
n ----> the number of additional red circles
----> equation B
substitute equation A in equation B

solve for n

therefore
The number of red circles to be added would be equal to 8 times the original amount of red circles
Answer:
The answer is B) y = Sin(3x)
Step-by-step explanation:
In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2
/3. Since Sin2
= 0, we need what is inside of the parenthesis to equal 2
.
The only thing that you could multiply 2
/3 by to get 2
m is 3. Therefore, we must have 3x in the original equation.
Answer:
$189.75
Step-by-step explanation:
Whenever you want to find the percent of something, you need to turn the percent into a decimal. In this case, we need to find 115% of the wholesale price because there is a markup, so the cost will be higher.
115% as a decimal is 1.15. Here is how the equation will be set up:
$165 • 1.15 = $189.75
No rounding is necessary for this problem because it is already to the nearest cent.
Answer:
Y=697
Step-by-step explanation:
Substitute the x with 225.
Y=3(225)+22
Therefore x equals 697
