Answer:
21
Step-by-step explanation:
First, you put all of the possiblities for the kitchen.
K1
K2
K3
K4
K5
K6
K7
Then, you multiply 7 by each room which would be 3 so,
3 * 7 = 21
So, 21 is probably your answer.
Lastly, have a great day!
There are 210 color arrangements possible
The number of rooms (r) in the house is given as:
[tex]r = 3[/tex] ---- i.e. the kitchen, dining room, and living room
The number of available colors (n) to select from is also given as:
[tex]n = 7[/tex]
The possible color arrangement is calculated using the following permutation formula
[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]
So, we have:
[tex]^7P_3 = \frac{7!}{(7 - 3)!}[/tex]
Remove bracket
[tex]^7P_3 = \frac{7!}{4!}[/tex]
Expand the numerator
[tex]^7P_3 = \frac{7 \times 6 \times 5 \times 4!}{4!}[/tex]
[tex]^7P_3 = 7 \times 6 \times 5[/tex]
[tex]^7P_3 = 210[/tex]
Hence, there are 210 color arrangements possible

An angle measures 26° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
103 & 77 degrees
Step-by-step explanation:
Supplements add up to 180 degrees.
I started at 90 & did:
90 + 13 = 103
(Because 13 * 2 is 26, but if you subtract 26 then the supplement will be 52 away & not 26)
180 - 103 = 77
103 - 77 = 26

Below is a system of equations. Which method would you use to solve this? Why? Solve the problem, explaining each step.
x = y – 3
2x + y = 12
Answer:
(using substitution to solve the problem)
x=y-3
2x+y=12
2(y-3)+y=12
2y-6+y=12
3y=18
y=6
y=6
x=6-3
= (3, 6)
Step-by-step explanation:
using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.

please help me on this question
Answer:
y = 2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 3 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, so
y = 2x + c ← is the partial equation of the line
To find c substitute (3, 1) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of parallel line
Find the value of x.
129 students went on a field trip. Five buses
were filled and 9 students traveled in cars.
How many students were in each bus
Answer: 24 students
Step-by-step explanation:
We know that there were 129 students total. However, of those 129 students, 9 traveled in cars, which means that only 120 students took the bus. We know there were five buses, so if the students filled the buses up equally, we can divide the number of bus riders by the number of buses to find the number of students per bus.
With 120 students and 5 buses, we get 120 ÷ 5 = 24.
Find the volume of the cone. Round your answer to the nearest tenth if necessary. Use 3.14 for it.
8 ft
6 ft
Answer:
75.4 ft³
Step-by-step explanation:
Volume of a cone = πr²h/3
π = 3.14
radius, r = diameter / 2
= 6ft/2
= 3 ft
Height, h = 8 ft
Volume of a cone = πr²h/3
= (3.14 * (3)² * 8) / 3
= (3.14 * 9 * 8) / 3
= 226.08 / 3
= 75.36
Volume of a cone = 75.36 ft³
Approximately to the nearest tenth = 75.4 ft³

Answer:
60
Step-by-step explanation:
10×2=20÷2=10×2=20 goes for the two top ones
20×2=40÷2=20×2=40 goes for the two bottom ones
40+20=60 is the answer
Answer:
60ft^2
Step-by-step explanation:
Split the area into two large triangles, the right and the left.
The base for the triangle is 10ft+20ft =30ft and we know the height is 2.
Since A=bh*1/2, A = 30*2*1/2. This equals 30. since there are two of these large triangles and they are equal, just multiply the area by 30.

Given:
In circle D, the measure of angle ADC is 108 degrees.
To find:
The measure of angle ABC.
Solution:
Central angle theorem: According to this theorem, the measure of central angle of an arc is twice of the measure of inscribed angle on that arc.
Using the Central angle theorem, we get
[tex]m\angle ADC=2\times m\angle ABC[/tex]
[tex]108^\circ=2\times m\angle ABC[/tex]
[tex]\dfrac{108^\circ}{2}= m\angle ABC[/tex]
[tex]54^\circ= m\angle ABC[/tex]
Therefore, the measure of angle ABC is 54 degrees.
