Step-by-step explanation:
Let's say x = number of customers, and y = number of tanks of gas.
The revenue is 10x.
The cost is 45y.
The profit is the revenue minus the cost. We want the profit to be at least $6000.
10x − 45y ≥ 6000

What is the value of x?
Answer:
x=12
Step-by-step explanation:
Intersecting Chords Formula:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
10 * x = ( 3+x) *8
10x = 24+8x
Subtract 8x
10x-8x = 24+8x-8x
2x= 24
Divide by 2
2x/2 =24/2
x = 12
An observer (O) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 ft., what is the distance (x) from the plane (P) to the observer (O)? (4 points)
If the plane is flying at an altitude of 21,000 feet, it is perpendicular to the observer's horizontal line of sight. Thus, I concluded that the given information be assigned to the attachment below.
Given -
( Observer at point O, plane flying at point P
( Plane at 55° angle to horizontal line of sight, altitude of 21,000 feet
The distance ( x ), is represented by the line segment OP, with which we have to determine the length of. Therefore we can conclude the following -
[tex]Sin( 55 ) = Altitude / Distance,\\Sin( 55 ) = 21,000 / x,\\----------------\\x = \frac{21,000}{Sin( 55 )},\\x = 21,000 / 0.81915204428\\\\x = ( About ) 25636 feet\\[/tex]
As you can see, the distance from the plane to the observer is about 25,636 ft!
Answer:
25,636 feet

The number of kilometers traveled by a bus is represented by x. If a train traveled 200 kilometers farther than the bus, represent the number of kilometers traveled by the train.
Answer:
The train travelled x + 200 km
Answer:
The number of kilometres traveled by the bus is x kilometres. The train travels 200 kilometres farther than the bus, meaning that the train traveled x kilometres, and an additional 200 kilometres.
So, the number of kilometres traveled by the train would be the x km traveled by bus, plus 200 km; or x + 200 km.

What does the graph of f(x)=3x^2-2x+1 look like
Answer:
Below.
Step-by-step explanation:
This is a parabola.
As the coefficient of x^2 is positive it will open upwards ( shaped like a 'U').
If we convert to vertex form we can find the line of symmetry and the coordinates of the vertex:
f(x) = 3x^2 - 2x + 1
f(x) = 3(x^2 - 2/3 x) + 1
f(x) = 3[(x - 1/3)^2 - (1/3)^2] + 1
f(x) = 3(x - 1/3)^2 - 1/3 + 1
f(x) = 3(x - 1/3)^2 + 2/3
So the line of symmetry is x = 1/3 and
the vertex ( the minimum of the curve) is at (1/3, 2/3).
Jayden measured a community college and made a scale drawing. He used the scale 22 millimeters : 9 meters. The actual length of a building at the college is 99 meters. How long is the building in the drawing?
Hey there! :)
Answer:
x = 242 mm.
Step-by-step explanation:
Begin by setting up a proportion between the actual college building and the drawing.
[tex]\frac{22mm}{9m} = \frac{x}{99m}[/tex]
Cross multiply:
99 × 22 = 9 × x
2178 = 9x
Divide both sides by 9:
2178/9 = 9x/9
x = 242 mm.

Answer:
x = 76 roses
Step-by-step explanation:
Step 1: Define variables
x = # of roses
y = # of tulips
Step 2: Write systems of equations
x = 4y + 8
5x + 2y = 414
Step 3: Use Substitution
5(4y + 8) + 2y = 414
20y + 40 + 2y = 414
22y = 374
y = 17
Step 4: Plug in y to find x
x = 4(17) + 8
x = 68 + 8
x = 76
Answer:
x = 76
Step-by-step explanation:
x = Roses
y = Tulips
x = 4y + 8
5x + 2y = 414
5(4y + 8) + 2y = 414
20y + 40 + 2y = 414
22y = 374
y = 17
x = 4(17) + 8
x = 68 + 8
x = 76

Solve the triangle. Round your answers to the nearest tenth.
Answer:
m∠A ≈ 43°
m∠B ≈ 55°
mBC ≈ 20
Step-by-step explanation:
Law of Sines: [tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]
Step 1: Find m∠B
[tex]\frac{29}{sin82} =\frac{24}{sinB}[/tex]
Step 2: Solve for ∠B
29sinB = 24sin82°
sinB = 24sin82°/29
B = sin⁻¹(24sin82°/29)
B = 55.038°
Step 3: Find m∠A
180 - (55.038 + 82)
180 - 137.038
m∠A = 42.962°
Step 4: Find BC
[tex]\frac{29}{sin82} =\frac{BC}{sin42.962}[/tex]
Step 5: Solve for BC
29sin42.962° = BCsin82°
BC = 29sin42.962°/sin82°
BC = 19.9581
Consider the function. f(x)= -2/3x-24 Which conclusions can be drawn about f–1(x)? Select two options. f–1(x) has a slope of -2/3 . f–1(x) has a restricted domain. f–1(x) has a y-intercept of (0, –36). f–1(x) has an x-intercept of (–36, 0). f–1(x) has a range of all real numbers.
Answer:
(D) [tex]f^{-1}{(x$) has an x-intercept of (-36, 0).[/tex]
(E)[tex]f^{-1}{(x)[/tex] has a range of all real numbers.
Step-by-step explanation:
Given the function: [tex]f(x)= -\dfrac23x-24[/tex]
[tex]f(x)+24= -\dfrac23x\\$Multiply both sides by $ -\dfrac32\\x=-\dfrac32(f(x)+24)\\f^{-1}(x)=-\dfrac32f(x)-36[/tex]
When y=f(x)=0
[tex]f^{-1}(x)=-\dfrac32(0)-36\\f^{-1}(x)=-36[/tex]
Therefore, [tex]f^{-1}(x)$ has a x-intercept of -36[/tex]
Also, [tex]f^{-1}(x)[/tex] has a range of all real numbers.
Therefore, Options D and E are correct.

Answer:
$110
Step-by-step explanation:
we know
selling price = cost price + profit.
given
selling price of TV = $121
profit = 10%of cost
selling price of TV = cost of TV + 10%cost of TV
121 = cost of TV + 10/100 cost of TV
=> 121 = (100 cost of TV + 10 cost of TV)/100
=> 121*100 = 110 cost of TV
=> cost of TV = 121*100/110 = 110
Thus, cost price of TV is $110(option A)

Answer:
2. -3, 1.
3. -2, 0.
4. 6, 8.
5. 20.
Step-by-step explanation:
2. x - 3y + 6 = 0
-3y = -x -6
y = 1/3x + 2
y + 4 = -5/4(x - 1)
y + 4 = -5/4x + 5/4
y = -5/4x + 5/4 - 16/4
y = -5/4x - 11/4
If you sketch these two lines on paper (or draw them on a graphing calculator), you will find that they intersect at (-3, 1).
So, the values you enter on the response would be -3, 1.
3. x + 3y = -2
x = -3y - 2
-3x + 5y = 6
-3(-3y - 2) + 5y = 6
9y + 6 + 5y = 6
14y + 6 = 6
14y = 0
y = 0
x + 3 * 0 = -2
x + 0 = -2
x = -2
-3 * -2 + 5 * 0 = 6
Since everything works out, the solution to the two equations is (-2, 0).
So, the values you enter on the response would be -2, 0.
4. 3x - 4y = -14
2x + 5y = 52
2(3x - 4y = -14)
3(2x + 5y = 52)
6x - 8y = -28
6x + 15y = 156
6x + 15y = 156
-6x + 8y = 28
23y = 184
y = 8
3x - 4 * 8 = -14
3x - 32 = -14
3x = 18
x = 6
2 * 6 + 5 * 8 = 12 + 40 = 52
Everything works out, so your solution is (6, 8).
Your answer will be (6, 8).
5. For a system of equations to have no solution, the y's and the x's must have the same coefficients.
5x - Ky - 10 = 0
y = 1/4x + 6
-Ky = -5x + 10
Ky = 5x - 10
1/5Ky = x - 2
1/20Ky = 1/4x - 1/2
1/20K = 1
K = 20
y = 1/4x - 1/2
y = 1/4x + 6
1/4x - 1/2 = 1/4x + 6
1/4x - 1/4x = 6 + 1/2
0 = 6.5
There is no solution, so K = 20.

A person is selected at random. What is the probability that the person uses exactly one of the facilities? There are 125 people in a sport centre. 59 people use the gym. 70 people use the swimming pool. 55 people use the track. 25 people use the gym and the pool. 30 people use the pool and the track. 17 people use the gym and the track. 6 people use all three facilities. A person is selected at random. What is the probability that the person uses exactly one of the facilities?
Answer:
Step-by-step explanation:
No of people using both gym and pool that is N( gup ) = 25
No of people using both track and pool that is N( tup ) = 30
No of people using both track and gym that is N( tug ) = 17
No of people using all that is N( gutup) = 6
No of people using two or three facilities
= 25+30+17- 2 x 6
= 60
Total no of people = 125
No of people using only one facility
= 125 - 60
= 65 .
Ratio of people using only one facility
= 65 / 125
.52
Required probability
= .52 .
probability that the person uses exactly one of the facilities
= .52
Jessica can paint 12 rocks in 8 minutes. How many rocks can she paint in 48 minutes
Answer:
72 rocks.
Step-by-step explanation:
A "easier" way to find out the answer, is to find how much rocks Jessica paints in 1 minute.
Divide 12 with 8:
12/8 = 1.5
Next, multiply the number you got (1.5) with 48:
48 x 1.5 = 72
Jessica can paint 72 rocks in 48 minutes.
~
Answer:
72 rocks
Step-by-step explanation:
So let’s create the following ratio 12:8
The 12 is the amount of rocks and the 8 is the time in minutes.
So we have to find how many rocks she can paint in 48 minutes.
So we make the following ratio x:48.
So we need to find x the amount of rocks she can paint in 48 minutes.
So to find x we have to divide 48 by 8 = 6.
So if the ratio is x6 we can just do 12 * 6 which is 72.
So she can paint 72 rocks in48 minutes.

Answer:
Step-by-step explanation:
Q1: <B = 150 °
If two parallel lines are cut by a transversal, then alternate interior angles are congruent.
8x-10 = 3x+90
5x=100 (subtract 3 from both sides)
x=20 (divide both sides by 5)
x = 20
<B= 3x +90
<B = 3 (20) +90
<B = 60 + 90
<B = 150
Q2: 62
An angles complement (not compliment, haha) is what the number that added to the angle equals 90°.
An angle is 34 more than its complement.
Let x represent the angle.
Let y represent its complement.
x= 34 +(90-x)
y= (90-x)
x + y = 90
34 + (90-x) + (90-x) =90
x= 62
Check the answer.
x= 34 more than complement.
62-34=28
62+28=90
Checked!
