The highest price per pizza in a profit of $100 is approximately $15.48
The profit equation is given by:
p = -5 [tex]x^2[/tex] + 100x - 250
Substitute p = 100 and solve for "x":
100 = -5 [tex]x^2[/tex]+ 100x - 250
To solve this quadratic equation, it can be rearranged it to standard form [tex](ax^2 + bx + c = 0)[/tex]
[tex]5x^2- 100x + 350 = 0[/tex]
Now, we can solve the quadratic equation using the quadratic formula:
[tex]x = \dfrac{(-b\pm \sqrt ({b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 5, b = -100, and c = 350. Substitute these values into the formula:
x =[tex]\frac{(\sqrt{(-100)^2 - 4 \times 5 \times 350}}{2\times5}[/tex]
x= [tex]\dfrac{{100 \pm\sqrt{3000}}}{10}[/tex]
Thus, the two possible solutions for "x":
[tex]x_1[/tex] =[tex]\dfrac{100 + \sqrt{3000}}{10}[/tex]
[tex]x_2[/tex] =[tex]\dfrac{100 - \sqrt{3000}}{10}[/tex]
Calculating the values:
[tex]x_1[/tex]≈ 15.48
[tex]x_2[/tex] ≈ 4.23
The highest price per pizza that results in a profit of $100 is approximately $15.48 (rounded to two decimal places).

Ratnam hired a car from a car renting agency which charges a flat amount of Rs x for travelling up to 40 kilometres and Rs. y per km for every kilometre travelled thereafter. How much should Ratnam pay the agency for a journey of 50 kilometres in Rs. ?
Answer:
Rs. X + Rs. 10y
Step-by-step explanation:
Charge for 40 km travel = Rs. x per km
Charge for every additional km traveled = Rs. y
Amount paid for 50 km
Fixed charge for 40km = Rs. X
Additional km = 50 - 40 = 10 kilometer
Total charge :

Step-by-step explanation:
We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6

Step-by-step explanation:
since these triangles are similar, we can use the triangle similitary theorem. This means that the sides are proportional to each other.
ef/bc = 5/45 (1/9) = ed/ba = 2/18 (1/9)
we can see the sides are in a ratio of 1:9, and plug it in the proportion
df/ac = 1/9

Answer:
B. ∠EAB and ∠CAD;
D. ∠CAB and ∠DAE
Step-by-step explanation:
Vertical angles are two angles formed directly opposite each other when two straight lines crosses or intercepts each other. Vertical angles are of equal measure to each other.
Thus, from the diagram given,
<CAD is vertically opposite to <EAB, also,
<CAB is vertically opposite to <DAE.
Thus, the vertical angles are:
∠EAB and ∠CAD;
∠CAB and ∠DAE

B.- 11.42 - 22.84 - 45.68 - 53.68
Answer:
Step-by-step explanation:
Part A: 24.50 feet, Part B: 46.68 square feet, I just took the test and got this right!
The perimeter of the figure is [tex]24.50[/tex] and area of the figure is [tex]45.68[/tex] square feet.
What is Area of Circle?
In geometry, the area enclosed by a circle of radius r is πr². Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159
According to question, the radius of the partial circle with center A is 4 feet.
We have to find the perimeter and area of the figure.
Perimeter of the figure=2πr×[tex]\frac{3}{4}[/tex] +[tex]4\sqrt{2}[/tex]
=2×[tex]3.14[/tex]×[tex]4[/tex]×[tex]0.75+4[/tex]×[tex]1.414[/tex]
[tex]=24.50[/tex]
Area of figure=[tex]\frac{3}{4}[/tex] πr²+[tex]r^{2}[/tex]×[tex]\frac{1}{2}[/tex]
=[tex]0.75[/tex]×[tex]3.14[/tex]×[tex]16[/tex][tex]+16[/tex]×[tex]0.5[/tex]
[tex]=37.68+8[/tex]
[tex]=45.68[/tex]
Hence, we can conclude that the perimeter of the figure is [tex]24.50[/tex] and area of the figure is [tex]45.68[/tex] square feet.

Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?
Answer:
65% of the orginal fee or $130.
Step-by-step explanation:
You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:
1: 100% = 10% + 25% + 65%
2: 200 = 20 + 50 + 130
3: 200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)
All of them basically mean the same thing it is just a matter of how you need it written.
Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.
Rodney has to pay $200 in three installments.
The third installment will be:
= Percentage in total - Percentages paid already
= 100% - 10% - 25%
= 65%
The third installment is therefore:
= Percentage to be paid x Amount
= 65% x 200
