1/2r + 2 (3/4r - 1) = 1/4r + 6
Answers
Answer:
r=32/7
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
1/2r+(2)(3/4r)+(2)(-1)=1/4r+6(Distribute)
1/2r+3/2r+-2=1/4r+6
(1/2r+3/2r)+(-2)=1/4r+6(Combine Like Terms)
2r+-2=1/4r+6
2r-2=1/4r+6
Step 2: Subtract 1/4r from both sides.
2r-2-1/4r=14r+6-14r
7/4r-2=6
Step 3: Add 2 to both sides.
7/4r-2+2=6+2
7/4r=8
Step 4: Multiply both sides by 4/7.
(4/7)*(7/4r)=(4/7)*(8)

7w+7=-4+4w+23 what is this?
Answers
Answer: 7w+7=-4+4w+23 = W = 4
First you have to simplify the equations
7w+7= (4w) + (-4+23) 7w+7= 4w+19
Than you have to subtract the 4w (both equation)
7w+7-4w =4w = 4w + 19 - 4w = 3w+7= 19
And than you have to subtract the sevens
3w+7-7=19-7=3w=12
than divide by 3
3w/3 equals 12/3w=4

Answer:
∠H = 122°
Step-by-step explanation:
This is a 5-sided polygon. That means the sum of all the angles must equal 540°.
∠H + 107° + 97° + 130° + 84° = 540°
∠H = 540° - (107° + 97° + 130° + 84°)
∠H = 540° - 418°
∠H = 122°

The function below was generated using an equation of the form f(x) = asin(bx – c). On a coordinate plane, a function has a maximum of 3 and minimum of negative 3. It completes one period at pi. It increases through the y-axis at (0, 0). Find a, b, and c for the function such that the graph of f matches the figure. a = 3, b = –2, c = π a = 2, b = 3, c = –π a = 3, b = 2, c = –π a = 2, b = -3, c = π
Answers
Answer: A
a = 3, b = –2, c = π
Step-by-step explanation:
The values of a, b and c for the function such that the graph of f matches the figure are;
a = 3, b = -2, c = π
We are given the equation as;
f(x) = a sin(bx - c)
Now, the general form of equation of a sinusoidal wave is;
y = Asin(ωt + ϕ)
Where;
A is the amplitude of the wave
ω is the wave's angular frequency,
ϕ is the phase of the sine wave in radians.
Comparing that general equation to the one we are given, we have;
a as the amplitude
c as the phase
Now, from the attached image of the graph, the amplitude it the peak of the wave which is 3.
Thus; a = 3
Now, the phase angle from the graph which is the interval for each period of motion of the wave is seen to be π. Thus, c = π
Looking at the options, the only one that has the correct value of a and c is option A.

Regal Cinemas sold a total of 8500 movie tickets. Proceeds totaled $64,600. Tickets can be bought in one of 3 ways: a matinee admission cost $5, student's admission is $6 all day, and regular admission are $8.50. How many matinee tickets were sold if twice as many student tickets were sold as matinee tickets? * Only type the number of matinee tickets that were sold
Answers
Answer:
900
Step-by-step explanation:
From the information given you can write the following equations:
x+y+z=8500 (1)
5x+6y+8.50z=64600 (2)
y=2x (3)
First, you can replace (3) in (2) and (1):
x+2x+z=8500
3x+z= 8500 (4)
5x+6(2x)+8.50z=64600
5x+12x+8.50z=64600
17x+8.50z=64600 (5)
Now, you have two equations:
3x+z= 8500 (4)
17x+8.50z=64600 (5)
Then, you can isolate z in (4):
z=8500-3x (6)
Next, you can replace (6) in (5):
17x+8.50(8500-3x)=64600
17x+72250-25.5x=64600
7650=8.5x
x=7650/8.5
x=900
You can replace the value of x in (3) to find y:
y=2x
y=2*900
y=1800
Finally, you can replace the value of x in (6) to find z:
z=8500-3(900)
z=8500-2700
z=5800
According to this, the answer is that 900 matinee tickets were sold.

The hourly wage increases each employee receives each year depends on the number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00 per hour. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00 per hour. Choose a function to represent this scenario
Answers
Answer:
________{0.50 if x < 3
________{1.00 if 3 ≤ x < 6
f(x) = ____{1.50 if 6 ≤ x < 9
________{2.00 if 9 ≤ x < 12
Step-by-step explanation:
Given the information above :
Less than Employees = $0.5 increase per hour
Atleast 3 but less than 6 years employees = $1.00 increase per hour
Atleast 6 but less than 9 years employees = $1.50 increase per hour
Atleast 9 but less than 12 years employees = $2.00 increase per hour
The information above can be written as a piecewise function :
________{0.50 if x < 3
________{1.00 if 3 ≤ x < 6
f(x) = ____{1.50 if 6 ≤ x < 9
________{2.00 if 9 ≤ x < 12
The constraints is represented in the piecewise function above with x being the number of years since employee has been in service.
