A 16-inch cheese pizza at Fine Dough Pizza costs $10.00 and each additional topping is $1.50. The same size pizza at Johnson's Pizza costs $8.00 and each additional topping is $2.00. After how many toppings do the pizzas cost the same? Which pizza costs more with additional toppings?
To find the number of toppings at which the pizzas cost the same, we can set the total cost expressions for both pizzas equal to each other and solve for 'x'. After 4 additional toppings, the pizzas will cost the same. With 5 additional toppings, Johnson's Pizza costs more.
Explanation:To find the point at which the pizzas cost the same, we need to determine the number of toppings that will make the total cost equal for both pizzas. Let's denote the number of additional toppings as 'x', and the cost of each additional topping at Fine Dough Pizza as $1.50, and at Johnson's Pizza as $2.00. The total cost for Fine Dough Pizza will be $10.00 + $1.50x, and the total cost for Johnson's Pizza will be $8.00 + $2.00x. To find the number of toppings at which the pizzas cost the same, we can set the two total cost expressions equal to each other and solve for 'x':
$10.00 + $1.50x = $8.00 + $2.00x
To solve the equation, we can subtract $1.50x from both sides:
$10.00 = $8.00 + $0.50x
Next, we subtract $8.00 from both sides:
$2.00 = $0.50x
To isolate 'x', we divide both sides by $0.50:
x = 4
Therefore, after 4 additional toppings, the pizzas will cost the same.
To determine which pizza costs more with additional toppings, we can compare the total cost expressions for both pizzas for a specific number of toppings. For example, let's consider 5 additional toppings:
Total cost at Fine Dough Pizza = $10.00 + $1.50(5) = $10.00 + $7.50 = $17.50
Total cost at Johnson's Pizza = $8.00 + $2.00(5) = $8.00 + $10.00 = $18.00
Therefore, with 5 additional toppings, Johnson's Pizza costs more.

Find the circumference of the circle if the square has an area of 144 m2. Give your answer to the nearest tenth. Use 3.14 form
The circumference of the circle is found by first determining the side length of the square, then using that to calculate the diameter and radius of the circle. Using 3.14 as an approximation for pi, the circumference is calculated to be 37.7 meters when rounded to the nearest tenth.
To find the circumference of the circle when the square has an area of 144 m², we first determine the side length of the square using the formula for the area of a square, A = a², where A is the area and a is the side length.
A = 144m²
a = 12m
Since the area is 144 m², the side length of the square is "12 m (since 12 x 12 = 144).
Since the circle fits perfectly within the square, the diameter D of the circle is equal to the side length of the square. Therefore, D = 12 m. The radius r is half the diameter, so in this case, r = 6 m.
The formula for the circumference C of a circle is C = 2πr.
C = 2 x 3.14 x 6 m = 37.68 m
The circumference is 37.7 m.

a.
Essential (flexible) expense
b.
Emergency fund
c.
Essential (fixed) expense
d.
Non-essential expense
Answer:
a. Essential (flexible) expense
Step-by-step explanation:
Most people consider a cell phone an essential expense, since they are used in power outages or emergencies while traveling.
This is a flexible expense, since there are extra fees for extra usage.
The phone bill expense is an Essential (flexible) expense so option (A) will be correct.
What is the reasoning?The procedure of utilizing logical reasoning to analyze a condition to determine the best problem-solving approach for a particular issue, then using this approach to create and explain a resolution.
In another word, reasoning is a tricky but interesting problem in mathematics that required relations of variables to solve.
The mobile cost is an essential cost because it is can be used in an emergency situation or it is very useful for calling massaging or video calling.
Since the plan for mobile recharge varies higher or lower according to benefits so it will be a flexible expense.
Hence "The phone bill expense is an Essential (flexible) expense".

P is the midpoint of QN, MP is perpendicular to to QN prove rectangle MRQ is congruent to rectangle MRN
By using the rules of geometry, we can determine that if P is the midpoint of QN and MP is perpendicular to QN, then rectangles MRQ and MRN are congruent. The congruency is due to the properties of rectangles, triangles, midpoints, and the Hypotenuse-Leg Theorem.
Explanation:The proof of the congruence of rectangles MRQ and MRN involves geometry rules, particularly the properties of rectangles, triangles, and midpoints. Let's consider rectangle MRQ and MRN. We know that in a rectangle, diagonals are congruent. If P is the midpoint of QN, that means QP = PN. Additionally, if MP is perpendicular to QN, PMQR and PMNR are right triangles with the same hypotenuse.
Using the properties of triangles, we can say that if two right triangles have a congruent hypotenuse and one leg (which is MP in both cases), then these triangles are congruent. Therefore, ∆PMQR is congruent to ∆ PMNR by the Hypotenuse-Leg (HL) Theorem.
Considering that ∆ PMQR ≅ ∆ PMNR and QP = PN, we can say that quadrilaterals MRQN and MRNP are each a parallelogram. Additionally, since MP is perpendicular to QN, quadrilaterals MRQN and MRNP are actually rectangles based on the definition of a rectangle (a parallelogram with a right angle). Therefore, rectangle MRQ is congruent to rectangle MRN.

2n^2+3n-9 factoring trinomials
The trinomial [tex]2n^2[/tex]+3n-9 cannot be factored using integers as no two numbers exist that multiply to give -18 (the product of the leading coefficient and the constant term) and add up to 3 (the middle coefficient).
To factor the quadratic trinomial [tex]2n^2[/tex]+3n-9, one must find two binomials that, when multiplied together, give the original trinomial. Factoring complex trinomials can sometimes be achieved by finding two numbers that multiply to give the product of the leading coefficient (2 in this case) and the constant term (-9 in this case), and add to give the middle coefficient (3 in this case). However, for this particular trinomial, such numbers do not exist, and it cannot be factored using integers. This means that either the trinomial is prime (cannot be factored), or it would require the quadratic formula to solve for factors involving irrational or complex numbers.
In 2000 Michigan had a population of 9,938,444. The number of people living in Michigan decreased by 0.6% in 2010. What was Michigan’s approximate population in 2010?
Answer:
9,878,813
Step-by-step explanation:
First, make 0.6% into a decimal
0.6 / 100 = 0.006
Then, multiply the number of people living in Michigan in 2000 by the number of people decreased (the percentage decrease) in 2010
9,938,444 x 0.006 = 59630.664
Last, subtract the percentage decrease by the original population in 2000
9,938,444 – 59630.664 = 9,878,813
In 2010 the approximate population in Michigan was about 9,878,813 (to the nearest whole person)
