Answer:
p= -80
Step-by-step explanation:
DON'T FORGET TO INCLUDE THE NEGATIVE
1. Isolate the p
2. Bring the .6 to the other side by doing the opposite. In this case adding.
3. You now should have -0.07=5.6
4. You are going to continue to isolate the variable.
5. You are going to do the opposite of multiplication to the -0.07. (Didn't know how to word this part)
6. You are going to divide both sides by -0.07. Which would give you -80.
DON'T FORGET TO INCLUDE THE NEGATIVE

If one gallon of gas costs $2.50, how many gallons of gas could you buy for $16.2
Answer:
The answer is
6 gallonsStep-by-step explanation:
In order to solve this question we use ratio and proportion.
From the question
$ 2.50 is the price of one gallon
To find the number of gallons that cost $16.2 , multiply $16.2 by one gallon and divide it by $ 2.50
That's
[tex] \frac{16.2 \times 1}{2.50} [/tex]
= 6.48
We have the final answer as
6 gallons
Hope this helps you
When the squares of two consecutive even integers are added, the sum is 244. Find
the integers.
A line segment starts at the point (2,3) and ends at the point (6,11). Find the equation of the perpendicular bisector of the segment. Demonstrate that your answer is correct. Your equation must be written in slope intercept form.
1). Slope = (-2)
2). Midpoint = (2, -2)
3). Slope of the perpendicular bisector = (1/2)
4). Equation of perpendicular bisector will be x - 2y = 6
Step-by-step explanation:
A line segment has the endpoints at (4, -6) and (0, 2).
1). Then the slope of the given line segment will be = (y - y')/(x - x') = (2 + 6)/(0 - 4) = 8/(-4) = (-2)
2). Mid point of the line segment is given by
Therefore midpoints of the line segment will be = (2, -2)
3). Slope of the perpendicular bisector is represented by
⇒ (-2)×m2 = (-1)
⇒
4). Now we have to find the equation of perpendicular bisector passing through (2, -2) and slope (1/2).
Since standard equation of the line will be given as y = mx + c
passes through (2, -2).
c = (-1) - 2 = -3
Finally the equation of perpendicular bisector will be
⇒ 2y = x - 6
⇒ 2y - x = -6
⇒ x - 2y = 6

If the one side of the rectangle is 8 ft and the other side is 3x-40, what is the area of
the rectangle?
Answer:
24x-320
Step-by-step explanation:
Area of a rectangle is length*width.
This basically means we have to multiply one of its sides with the other side.
Hence, our expression would be:
8(3x-40)
Simplify by distributing.
8*3x+8*-40
24x-320
The area of the rectangle is 24x-320.

Answer:
(a) Regression Equation : x = 6.33333y + 38.6875,
(b) Test Score will be about 89.4% if student sleeps 8 hours a night
Step-by-step explanation:
Using a regression calculator your equation should be as follows, where x = test scores, and y = average sleep.
(a) Solution : x = 6.33333y + 38.6875
We can check if this equation is ' suitable ' by plugging in the value 7 for y, and expecting an outcome of around 88 percent ...
x = 6.33333(7) + 38.6875 = 44.33331 + 38.6875
= 83.02061% - this may seem a bit too off, but it is predictable
Now let's plug in 8 for y, as to calculate the percent when a student sleeps for 8 hours ...
x = 6.33333(8) + 38.6875 = 50.66664 + 38.6875
= 89.35414% ≈ 89.4%
(b) Solution : Test Score will be about 89.4%
A shop buys a pair of shoes for $50. They sell them for $60. What is the mark–up on the shoes? in dollars
Answer:
the mark-up is $10 or 20% of the original price.
Step-by-step explanation:
This is because 60-50 is 10. And 20% or 1/5 of 50 is 10.
A ship leaves Coffs Harbour and sails 320 km east. It then changes direction and sails 240 km due
north to its destination. What will the ship's bearing be from Coffs Harbour when it reaches its
destination, correct to two decimal places?
Answer: Bearing = 41.41°
Step-by-step explanation:
[tex]\tan \theta=\dfrac{opposite}{adjacent}\\\\\\\tan \theta=\dfrac{240}{320}\\\\\\.\quad \theta=\tan^{-1}\bigg(\dfrac{240}{320}\bigg)\\\\\\.\quad \theta =48.59^o[/tex]
Bearing is measured clockwise from North (90° on a Unit Circle = bearing of 0°)
Bearing = 90° - Ф
= 90° - 48.59°
= 41.41°

x -3y -3 =0 3x-9y-2=0
Answer:
No solution.
Step-by-step explanation:
x - 3y - 3 = 0
3x - 9y - 2=0
Multiply the first equation by - 3:
-3x + 9y + 9 = 0
Add this to the second equation:
0 + 0 + 7 = 0
0 = -7 , which is absurd so there is no solution to this system.
Can you write a rule for finding the output (absolute guessing error) given the input (a guess)?
Answer:
The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]
Step-by-step explanation:
The coordinates when y = 0, x = 50
When y = 10, x = 60
Therefore, the slope = (10 - 0)/(60 - 50) = 1
The equation in slope and intercept form is y - 10 = 1 × (x - 60)
y = x -60 + 10 = x -50
y = x - 50
Also, we have
When y = 20, x = 30
y = 10, x = 40
Therefore, the slope = (10 - 20)/(40 - 30) = -1
The equation in slope and intercept form is y - 10 = -1 × (x - 40)
y = -x + 40 + 10
y = 50 - x
Therefore, when x < 50, y = 50 - x
When x > 50, y = x - 50
Which is equivalent to [tex]y = \left | x - 50 \right |[/tex]
The rule for the plotted line is [tex]y = \left | x - 50 \right |[/tex]

Find the value of 2.
A.126
B.121.5
C.117
D.63
Answer:
D
Step-by-step explanation:
The tangent- tangent angle x is half the difference of the intercepted arcs.
The sum of the 2 arcs on the circle = 360°, thus
lower arc = 360° - 243° = 117°, then
x = [tex]\frac{1}{2}[/tex] (243 - 117)° = 0.5 × 126° = 63°

Answer:
Area = (x² + 11x + 24)
Step-by-step explanation:
Area of the blue square with sides 'x' units = (Side)²
= x²
Area of the pink rectangle = Length × width
= 3 × (x)
= 3x
Area of the orange rectangle = Length × Width
= 8 × 3
= 24
Area of the green rectangle = Length × width
= (x) × 8
= 8x
Now total area of the entire rectangle = x² + 3x + 24 + 8x
= (x² + 11x + 24)
Therefore, area of the entire rectangle will be a polynomial (x² + 11x + 24)
