Answer:
There are 24 green marbles.
Step-by-step explanation:
Let x be the number of green marbles, then:
3/2 = 36/x
3x = 2*36
3x = 72
x = 24.
Answer:
y = 20*4^x
Step-by-step explanation:
to find the value of the constants a and b, we just need to use the points given in the equation and solve the system of equations:
point (0,20): x = 0 and y = 20:
20 = a*b^0 = a*1 = a
a = 20
point (2,320): x = 2 and y = 320
320 = 20 * b^2
b^2 = 16
|b| = 4
b = 4 or b = -4
So we have two exponencial equations that pass through these points:
y = 20*4^x and y = 20*(-4)^x
As the questions asks for just one equation, we can answer y = 20*4^x
Answer:
[4, positive infinity)
Step-by-step explanation:
since there is a closed circle on 4, we include 4 in the continuous interval, and we assume that the arrow represents continuity after the graph ends, so the interval of continuity is from 4 to positive infinity.
You have to line them up for example 1 is in a straight line and so is 3 and 5 you can choose between 3 and five but what about the middle 4.
Answer: 127 cookies
Step-by-step explanation:
1. If you look back to the text you will see that 12 is 1 in 1:3:4 and you multiply that by 2. 12 * 2 = 24.
2. Divide 24 by 3 and that gives you 8 than times it by 5 for it to give you 40
3. Divide 36 by 4 and that equals to 9 than multiply it by 7 which that gives you 63
4. Add 24, 40, and 63 for it to give you 127
Thank you for following these steps if it is correct and this is my first time so if I am incorrect I will look upon my mistake and correct and help many of you people who need help
