Answer:
Cost = cost of first painter + cost of second painter
= $12/hr * hours worked + $11 * hours worked
where x is the hours the first painter works
C(x) = 12 x + 11 ( 15 - x)
= 12 x + 165 - 11x
= x + 165
C(x,y) = 12 x + 11 y
where y = 15 - x because the total hours is 15

Answer:
231.00
Step-by-step explanation:
Carol earns 16 for 30 minutes, so $32 an hour, 32 * 3 = 96.
Peter earns 15 every 20 minutes, so 20 * 3 = 60 minutes, and 15 * 3 = 45,
so he earns 45 dollars an hour. 45 * 3 = 135
135+96 = 231.00

A)
12 units
B)
64 units
C)
32 units
D)
24 units
Answer:
D. 24 Units
Step-by-step explanation:
tracing the points given we get a rectangle
the perimeter of a rectangle = 2a+2b
a=length
b= width
in this case a= 8
b= 4
the perimeter of a rectangle = (2*8)+(2*4)
the perimeter of a rectangle = 16+8
the perimeter of a rectangle = 24

does anyone understand slope intercept form? ugh
Answer:
Yes I do the formula is y=mx+b This means the answer is B
Step-by-step explanation:
You can ignore this if you already know the parts of the equation but here is it broken down. the X and Y in the slope intercept equation are left blank if you are given the slope and y-intercept like you were in this problem. The M in th equation stands for the slope which is 1/2 in this problem. B stands for the Y-intercept which just means where is the line crossing the y-axis when x is zero. I hope this helps you.

Make r the subject of the formula t=r/r-3
Answer:
[tex]r = \frac{3t}{t-1}[/tex]
Step-by-step explanation:
[tex]t = \frac{r}{r - 3}[/tex]
Cross multiply,
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t -1) = 3t
[tex]r = \frac{3t}{t-1}[/tex]
Answer:
r = 3t/(t - 1)
Step-by-step explanation:
t = r/(r - 3)
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t - 1) = 3t
r = 3t/(t - 1)

The value of the variable 'x' is 30°. Then the measure of the angle ∠C will be 60°.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
A triangle labeled A B C. Side BC is the base, side AB is perpendicular, and side AC is the hypotenuse. Angle A is labeled x degrees, angle B is labeled 3x degrees, and angle C is labeled 2x degrees.
Then the equation is given as,
x + 2x + 3x = 180°
6x = 180°
x = 30°
Then the measure of the angle ∠C is calculated as,
∠C = 2 × 30°
∠C = 60°
The value of the variable 'x' is 30°. Then the measure of the angle ∠C will be 60°.

There are three clubs at Redwood High School: Debate, Student council, and Key club. There are 1000 students in the school. And everyone is in at least one club.
• The total number of students in the debate club is 310
• The total number of students in the Student council is 650
• The total number who are in debate and student council is 170
• The total number of students who are in both debate and the key club are 150
• The total number of students who are in both student council and the key club is 180
• There are 50 students who are in all three clubs How many students are in the key club?
Answer:
The number of students in the key club is 490
Step-by-step explanation:
The given parameters are;
The number of student in the school = 1000
The total number of student in the debate club = 310
The total number of student in the student council = 650
The total number of student who are in debate and student council = 170
The total number of student who are in both debate and the key club = 150
The total number of student who are in both student council and the key club = 180
The number of students who are in all three clubs = 50
Therefore, we have;
Let A represent the number of students in the debate club
Let B represent the number of students in the student council
Let C represent the number of students in the key club
We have;
n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(C∩A) + n(A∩B∩C)
Where;
n(A∪B∪C) = 1000
n(A) = 310
n(B) = 650
n(A∩B) = 170
n(B∩C) = 180
n(C∩A) = 150
n(A∩B∩C) = 50
Therefore;
n(C) = n(A∪B∪C) - (n(A) + n(B) - n(A∩B) - n(B∩C) - n(C∩A) + n(A∩B∩C))
Substituting the values gives;
n(C) = 1000 - (310 + 650 - 170 - 180 - 150 + 50) = 490
The number of students in the key club, n(C) = 490.

Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1

The applicable rule of exponents is ...

Of course, it can be useful to understand how moving the decimal point changes the exponent:

A vegetable garden is in the shape of a parallelogram with the dimensions shown.Parallelogram A B C D is shown. The length of A B is (4 r minus 2) feet, the length of B C is (2 r + 12) feet, and the length of A D is (3 r + 8) feet.
How many feet of fencing are needed to enclose the garden?
54 feet
68 feet
108 feet
140 feet
Answer:
t needs 68 feet to enclose the garden.
Step-by-step explanation:
In this problem, we are to solve the sides of a parallelogram ABCD to know the measurement to enclose a garden.
Take note that a parallelogram has two equal lengths and two equal widths. Let us assume that the parallelogram AB = CD is the length and AD = BC is the width.
Solving the problem
First, let us solve for r using the condition AD = BC
AD = BC
3r + 8 = 2r + 12
Simplify the equation
3r - 2r = 12 - 8
r = 4
Next, let us substitute the value of r to AB, BC, CD, and AD.
For AB:
AB = 4r - 2
AB = 4(4) - 2
AB = 16 - 2 = 14
For BC:
BC = 2r + 12
BC = 2(4) + 12
BC = 8 + 12 = 20
For AD:
AD = 3r + 8
AD = 3(4) + 8
AD = 12 + 8 = 20
For CD:
But AB = CD Therefore, CD = 14
Finally, let us solve the perimeter of the parallelogram
Perimeter = AB + BC + CD + AD
Perimeter = 14 + 20 + 20 + 14
Perimeter = 68 feet
Therefore, the fencing needed to enclose the garden is 68 feet.
