Answer:
60 degrees
Step-by-step explanation:
The wheel is a circunference, so it has a total of 360 degrees. As we have 12 chairs evenly spaced, this 360 degrees will also be divided evenly, so the angle between each pair of chairs is equal to 360 / 12 = 30 degrees.
As we want the angle between chairs B and D, we have two spaces between chairs (the space between B and C and the space between C and D), so the angle is 2 * 30 = 60 degrees
Okay. What I know so far is that the integers will all be negative. We don't have to count too high to do this. So for this, it's like pick any four numbers. Or you could divide 18 by half and find the addition problems that you know would equal 9. What I see is that -3 + -4 + -5 + -6 = -18. There are all four consecutive integers. The trend is that you can draw a line tracing to the number of the opposite side of the question and you can see they each equal nine. Most people would be tricked and say 6, because they ignore the negative symbol, but here's the catch. The lower the number in front of the negative sign, the greater it is. So in this case, the lowest number in front of the negative symbol is 3, which would also mean that -3 is the highest when it comes to all of these numbers. So -3 is the greatest out of the four consecutive integers.
Answer:
212 children, and 265 adults
Step-by-step explanation:
To find the number of children and adults, we can set up a systems of equations.
x= number of children
y= number of adults
Equation 1: Price
1.50x+2.25y=914.25
Equation 2: Total number of people
x+y=477
Now, let's solve the equation using substitution.
Rearrange the second equation to solve for one variable.
x+y=477
x=477-y
Now plug x equals into the first equation, and solve for y.
1.50x+2.25y=914.25
1.50(477-y)+2.25y=914.25
715.5-1.50y+2.25y=914.25
715.5+0.75y=914.25
0.75y=198.75
y=265
We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.
x+y=477
x+265=477
x=212
Lana = x
Pam = 0.5x - 0.05
Cheryl = 0.5x - 0.05 + 3.10
Total 89$ = Lana + Pam + Cheryl
89 = x + 0.5x - 0.05 + 0.5x - 0.05 + 3.10
89 = 2x + 3
89 - 3 = 2x
86 = 2x
86/2 = x
43 = x
then Pam = 0.5(43) - 0.05
= 21.50 - 0.05
= 21.45
Cheryl = 21.45 + 3.10
= 24.55
