Shane has $15,000 property damage insurance and $4,000 comprehensive and collision insurance with a $500 deductible. He slides on ice and hits a parked car, causing $8,500 worth of damage. The accident causes $6,750 of damage to his own car. How much will the insurance pay to fix both cars?
If the accident causes $6,750 of damage to his own car. The amount that the insurance company will pay to fix both cars is $14,750.
Insurance coverageUsing this formula
Insurance coverage=Total cost of damages-Deductible
Where:
Total cost of damages=($8,500+$6,750)
Deductible=$500
Let plug in the formula
Insurance coverage=($8,500+$6,750)-$500
Insurance coverage=$15,250-$500
Insurance coverage=$14,750
Therefore the amount that the insurance company will pay to fix both cars is $14,750.

Evan drops a ball vertically from a height of 150 ft. The peak height after each bounce is half the previous height. How many feet does the ball travel from the time he drops the ball until it reaches the peak height after the 6th bounce? Show all steps used to find the solution.
Answer:
442.96875 ft.
Step-by-step explanation:
Original Height (h) : 150 ft
Bounce 1 (h₁) : h/2 = 150/2 = 75 ft
Bounce 2 (h₂) : h₁/2 = 75/2 = 37.5 ft
Bounce 3 (h₃) : h₂/2 = 37.5/2 = 18.75 ft
Bounce 4 (h₄) : h₃/2 = 18.75/2 = 9.375 ft
Bounce 5 (h₅) : h₄/2 = 9.375/2 = 4.6875 ft
Bounce 6 (h₆) : h₅/2 = 4.6875/2 = 2.34375 ft
Finding the sum of bounces 1 - 5 :
75 + 37.5 + 18.75 + 9.375 + 4.6875 112.5 + 18.75 + 9.375 + 4.6875131.25 + 9.375 + 4.6875140.625 + 4.6875145.3125 ftDistance traveled :
Original Height + 2 x Sum of Bounces (1 - 5) + Height of 6th bounce150 + 2 x 145.3125 + 2.34375150 + 290.625 + 2.34375440.625 + 2.34375442.96875 ft.
Answer:
442.96875 ft
Step-by-step explanation:
We can model the height of each bounce as a geometric series.
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)
If we let n be the number of bounces, then the initial term has to be:
[tex]a_1=\dfrac12(150)=75[/tex]
since this is the height of the ball after the first bounce.
The common ratio r has already been given to us, as we have been told that the height of the bounce halves after each bounce.
[tex]\implies r=\dfrac12=0.5[/tex]
Therefore, the geometric series to model the peak height of each bounce is:
[tex]a_n=75(0.5)^{n-1}[/tex]
(where [tex]a_n[/tex] is the height and n is the number of bounces)
Therefore, to calculate the total number of feet the ball travels until it reaches the peak height of the 6th bounce:
Total = 150 + (2 × sum of 1, 2, 3, 4 & 5th bounces) + 6th bounce
To find the sum, use the geometric sum formula:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Therefore, the sum of the bounces 1 through 5 is:
[tex]\implies S_5=\dfrac{75(1-0.5^5)}{1-0.5}=145.3125[/tex]
Height of the 6th bounce:
[tex]\implies a_6=75(0.5)^{6-1}=2.34375[/tex]
[tex]\begin{aligned}\textsf{Total distance} & =150+2\left(\dfrac{75(1-0.5^5)}{1-0.5}\right)+75(0.5)^{6-1}\\ & = 150 + 2(145.3125)+2.34375\\ & = 150 + 290.625+2.34375\\ & =442.96875\: \sf ft \end{aligned}[/tex]
A search plane carries radar equipment that can detect metal objects (like submarine periscopes or plane wreckage) on the ocean surface up to 15.5 miles away. If the plane completes a circular flight pattern of 471 miles in circumference, how much area will it search?
The area that the considered search plane searches with the given figures is 16957.42 miles² approximately.
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex] sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex] sq. units
How are radius and circumference of a circle related?Suppose that a considered circle has:
Circumference = C unitsRadius = r unitsThen, we get:
[tex]C = 2\pi r \: \rm units[/tex]
So, the radar scans the surface of ocean in a circular area with radius of 15.5 miles.
That circular area is itself moved in a circular path (due to circular motion of the plane with 471 miles circumference of the circular path).
The graph given describes the region of scan.
The blue region's area = Outer circle's area - Internal circle's area
The Internal circle has circumference 471 miles, let its radius be 'r' miles, then:
[tex]471 = 2\pi r\\\\r = \dfrac{471}{2\pi} \: \rm miles[/tex]
The outer circle has the radius = internal circle's radius + diameter of the radar circle = [tex]\dfrac{471}{2\pi} + 2(15.5) =\dfrac{471}{2\pi} + 30 \: \rm miles[/tex]
Thus, we get:
Area of internal circle = [tex]\pi r^2 = \pi \times \left( \dfrac{471}{2\pi} \right)^2 \approx 17,653.56 \: \rm miles ^2[/tex]Area of outer circle = [tex]\pi \times \left( \dfrac{471}{2\pi} + 30 \right )^2 \approx 34610.98 \: \rm miles ^2[/tex]Net area which is searched by the search plane ≈ 34610.98 - 17653.56 miles²
Net area which is searched by the search plane ≈ 16957.42 miles²
Thus, the area that the considered search plane searches with the given figures is 16957.42 miles² approximately.

Question no.1:
Debbie bought 8 oranges and 7 apples for $10.20. Katrina bought 5 oranges and 14 apples for $12.15. How much did one apple and one orange cost?
Solution:
Let the cost of one apple be "y" and the cost of one orange be "x".
Here,
According to question,
8x + 7y = $10.20 5x + 14y = $12.15
=> 5(8x + 7y) = 10.20 × 5 => 8(5x + 14y) = 12.15*8
=> 40x + 35y = 51 -->(i) => 40x + 112y = 97.2-->(ii)
By Elimination method,
Equation (i) - (ii)
(40x + 35y) - (40x + 112y) = 51 - 97.2
=> 40x + 35y - 40x - 112y = - 46.2
=> - 77y = - 46.2
=> y = 46.2/77
=> y = 0.6
Putting the value of "y" in equation (i) we get,
40x + 35y = 51
=> 40x + 35 × 0.6 = 51
=> 40x + 21 = 51
=> 40x = 51 - 21
=> 40x = 30
=> x = 0.75
Therefore the cost of one orange is $0.75 and the cost of one apple is $ 0.6.Question no.2:
Joel and Janie are selling fruit. Joel sold 2 small boxes of fruit and 5 large boxes for $31. Janie sold 4 small boxes of fruit and 7 large boxes for $47. How much does one small box of fruit and one large box of fruit cost?
Solution:
Let the cost of a small box be "x" and the cost of a large box be "y".
Here,
According to question,
2x + 5y = $31 4x + 7y = $47
4(2x + 5y) = 31 × 4 2(4x + 7y) = 47 × 2
=> 8x + 20y = 124 ->(i) => 8x + 14y = 94 ->(ii)
By Elimination method,
Equation (i) - (ii)
(8x + 20y) - (8x + 14y) = 124 - 94
=> 8x + 20y - 8x - 14y = 30
=> 6y = 30
=> y = 30/6
=> y = 5
Putting the value of "y" in Equation (ii) we get,
8x + 14y = 94
=> 8x + 14 × 5 = 94
=> 8x + 70 = 94
=> 8x = 94 - 70
=> 8x = 24
=> x = 24/8
=> x = 3
Therefore, the cost of a small box is $3 and the cost of a large box is $5.Please help me :) :)))))))

Angle 1 and angle 2 are supplementary. Angle 2 is 2 times the measurement of angle 1. What is the measurement of the larger angle?
Answer: The larger angle (Angle 2) is 120 degrees
Step-by-step explanation:
Let's call Angle 1 x and call Angle 2 y.
Two angles being supplementary means that they add to 180.
This means x+y=180
Angle 2 is twice the measurement of angle 1.
This means 2x=y and that we can sub 2x in for y
x+2x=180
3x=180
Now solve for x
[tex]3x=180\\\frac{3x}{3} =\frac{180}{3} \\x=60[/tex]
We know the value of x, so now let's sub in to find the value of y
[tex]2x=y\\2(60)=y\\120=y[/tex]

From the question, it tells us that each angle was congruent to its opposite angle, since in a rectangle all angles are 90 degrees, rectangles won’t be correct. Parallelograms is self explanatory. Rhombuses have 2 pairs of same angles, which only leads to a trapezoid with 2 different bases, leading to different angles in it’s opposite corner.

how do you convert a quadratic equation from standard form into factored form?
Step-by-step explanation:
I’m assuming that you’re asking about quadratic equations, but suffice it to say that the method may even work for polynomials of higher degrees.
Let’s take an example. You have x^2+6x+8.
First, multiply the term in x^2 with the constant; in this case we get 8x^2.Next, break the value in x into two numbers, such that when you add them, the value becomes that of the middle term and when you multiply them, the value becomes that which you have just calculated.
Step 1:
x^2 * 8= 8x^2
Step 2:
(break the middle term)
x^2+4x+2x+8 (notice how 4x when added to 2x gives 6x but when multiplied, gives 8x^2)
Step 3:
(separate the common terms)
x(x+4)+2(x+4)
(x+2)(x+4)
