Review the table.
A 2-column table with 4 rows. Column 1 is labeled x with entries pi, StartFraction 7 pi Over 6 EndFraction, StartFraction 5 pi Over 4 EndFraction, StartFraction 4 pi Over 3 EndFraction. Column 2 is labeled y = sine (x) with entries 0, blank, blank, blank.
Which values, in order, will complete the table?
Answer:
I think that the answer is A.
Step-by-step explanation:
The values that complete the table are -1/2, -√2/2 and -√3/2
How to complete the table of values?The function is given as:
[tex]y = sin(x)[/tex]
From the table, we have:
sin(π) = 0
Next, we calculate the value of y for other values of x
When x = 7π/6, we have:
sin(7π/6) = -1/2
When x = 5π/4, we have:
sin(7π/6) = -√2/2
When x = 4π/3, we have:
sin(4π/3) = -√3/2
Hence, the values that complete the table are -1/2, -√2/2 and -√3/2

1. (02.01 MC) Celine has a bottle that contains 20% milk and the rest water. The bottle has 1 liter of water. Part A: Write an equation using one variable that can be used to find the total number of liters of milk and water in the bottle. Define the variable used in the equation. (5 points) Part B: How many liters of milk are present in the bottle? Show your work. (5 points) (10 points)
Answer:
A. Total number of liters = 1.25 liters
B. Milk = 0.25 liters
Step-by-step explanation:
Let
x = total number of liters ( milk + water )
Milk = 20% of x
= 0.2x
Water = 1 liter
Total number of liters = milk + water
x = 0.2x + 1
x - 0.2x = 1
0.8x = 1
Divide both sides by 0.8
x = 1 / 0.8
= 1.25
x = 1.25 liters
Total number of liters = 1.25 liters
B.
Liters of milk in the bottle = Total number of liters - liters of water
= 1.25 liters - 1 liter
= 0.25 liter
Milk = 0.25 liters

EMERGENCY! Please give me the correct answer!
Answer:
The answer is yes!
Step-by-step explanation:
I'm 100% sure, put it into a calculator and it'll give you 1 as the answer.
Answer:
Yes
Step-by-step explanation:
The answer is yes because:
1) As you can see, in standard form the pattern is x * 3 = y
2) If x = 1 it would match the pattern because the next number will be 1 x 3 which is 3, and then the the third number would be 3 x 3 = 9, and then the fourth number would be 9 x 3 = 27 and so on.

The entry ticket to a local football game costs $12 for an adult and $8 for a child. A group of 100 people paid an entry fee of $1,056. How many adults and how many children were there in this group? Drag the correct value to the appropriate box.
Step-by-step explanation:
let x be the number of adults and y number of childrens
so we have. x+y=100 people
and. 12*x+8*y=1056 dollars
x=100-y
replace 100-y to the second equation
12*(100-y)+8y=1056
1200-12y+8y=1056
1200-4y=1055
1200-1056=4y
144=4y
y=144/4=36
so x=100-y=100-36=64
so in this group were 64 adults and 36 childrens
In this group were 64 adults and 36 children.
What is system of equation ?In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.
let x be the number of adults and y number of children
so we have. x + y = 100 people
and. 12 × x + 8 × y = 1056 dollars
x=100 - y
replace 100 - y to the second equation
12 × (100 - y) + 8y = 1056
1200 - 12y + 8y = 1056
1200 - 4y = 1055
1200 - 1056 = 4y
144 = 4y
y = 144/4 = 36
so x = 100 - y = 100 - 36 = 64
Hence, in this group were 64 adults and 36 children.
