Answer:
The answer to the proportion is 45:25.
Step-by-step explanation:
To solve this proportion, we can use cross multiplication. That is, we can multiply the numerator of the first ratio (45) by the denominator of the second ratio (10) and the numerator of the second ratio (50) by the denominator of the first ratio (?). This will give us
45 x 10 = 500 and 50 x ? = 500.
If we divide both sides of the equation by 50, we get
? = 25.
Therefore, the answer to the proportion is 45:25.
The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pizza, p.
A graph titled Lunch Cost. The x-axis shows the number of slices purchased, numbered 1 to 8, and the y-axis shows the cost in dollars, numbered 5 to 40. Blue diamonds appear at points (0, 7.5), (1, 10), (2, 12.5), (3, 15), (4, 17.5), (5, 20), (6, 22.5), (7, 25), (8, 27.5).
For each additional slice of pizza that is purchased, by how much does the total cost of lunch increase?
$1.50
$2.00
$2.50
$3.00
Answer:
The correct option is $2.50.
Step-by-step explanation:
This can be determined by calculating the change in total cost of lunch using the data given in the question as follows:
Slice of pizza Total cost of lunch ($) Change in total cost of lunch ($)
0 7.5 -
1 10 2.5
2 12.5 2.5
3 15 2.5
4 17.5 2.5
5 20 2.5
6 22.5 2.5
7 25 2.5
8 27.5 2.5
Since the change in total cost of lunch in table abov is constant at $2.50, this implies that for each additional slice of pizza that is purchased, the total cost of lunch increases by $2.50.
Therefore, the correct option is $2.50.

What are the intervals of 5?
The set of numbers x such that 0 ≤ x ≤ 5 is an interval containing 0, 5, and all numbers between 0 and 5.
Interval notation is a way of representing intervals on the number line. That is, how to write a subset of the real number line. Intervals include numbers between two specific numbers.
In mathematics, a (real) interval is a set of real numbers containing all real numbers between any two numbers in the set. For example, the set of numbers x such that 0 ≤ x ≤ 1 is an interval containing 0, 1, and all numbers in between. Other examples of intervals are the set of numbers with 0 < x < 1, the set of all real numbers, the set of non-negative real numbers, the set of positive real numbers, the empty set, and any Singleton (a set of one element).
Real intervals play an important role in integral theory. This is because real intervals are the simplest set whose "length" (or "scale" or "magnitude") is easy to define. The notion of measure can be extended to more complex sets of real numbers, leading to the Boral measure and finally the Lebesgue measure.
Intervals are central to interval arithmetic, a general numerical technique that automatically provides guaranteed bounds for any mathematical expression, even in the presence of uncertainties, mathematical approximations, and arithmetic rounding.

what is polygon ?A polygon is a closed object in a two-dimensional plane comprised of line segments rather than curves. The word "polygon" is a combination of the words "poly" (which meaning many) and "gon" (means sides). A closed figure must include a minimum of three line segments that connect end to end. A polygon is any three or more-sided closed two-dimensional shape. In addition to more complex designs like a dodecagon with twelve sides, polygons include triangles and squares. Polygons include shapes like quadrilaterals, triangles, hexagons, and pentagons. The number of sides the form has is indicated by the name.

Answer: C = 12
Step-by-step explanation:
A = x
B = x[tex]\sqrt{3}[/tex]
C = 2x
So then to find A we divide B by [tex]\sqrt{3}[/tex], which makes A =6. But C = 2x, so then C = 2(6), which equals 12. Hope that helps :)

Is NP an undecidable problem?
Therefore , the solution of the given problem of NP-complete problem comes out to be that every NP problem is decidable.
Define NP-complete problem.Nondeterministic polynomial-time complete is referred to as "NP-complete" in short. In this nomenclature, the phrase "nondeterministic" refers to stochastic Turing machines, a technique of theoretically formalizing the concept of a brute-force search process.
Here,
Consider that each NP problem can be resolved.
This is a crucial idea.
Since P problems also fall under the concept of NP, it is possible that P vs. NP may not be dependent on established formal frameworks like ZF set theory (i.e., neither provable nor disprovable in them).
Certain NP-Hard issues can also be found in NP.
It follows that any NP problem is decidable as the answer to the given NP problem.
Therefore , the solution of the given problem of NP-complete problem comes out to be that every NP problem is decidable.

Joshua is going to invest $490 and leave it in an account for 5 years. Assuming the interest is compounded continuously, what interest rate, to the nearest tenth of a percent, would be required in order for Joshua to end up with $620?
Answer: 4.7%
Step-by-step explanation:
A=Pe^rt
A=620. P=490. t=5
620 = 490e^r(5)
620/490 = 490e^5r/490
1.2653061 = e^5r
In(1.2653061) = In(e^5r)
In (1.2653061)/5 = 5r/5
0.0470628 = r

Write 5 2/3+2 1/5 as a mixed number
Answer: 7 13/15
Step-by-step explanation:
First of, you have to get your common denominator, as it's impossible without one.
The closest common denominator is 15, and it will ask you for a simplified version.
Multiply the 2/3 in 5 2/3 by 5 on both sides to get 5 10/15
Multiply the 1/5 in 2 1/5 by 3 on both sides to get 2 3/15
Then add up your sum.
5 10/15+2 3/15=7 13/15
Answer:
7 13/15
Step-by-step explanation:
5 2/3+2 1/5
We need to get a common denominator for the fraction
3*5 = 15
2/3 *5/5 = 10/15
1/5 * 3/3 = 3/15
5 10/15 + 2 3/15 = 7 13/15
2x+2y=-6 what is it solved into a y=Mx+b
The equation 2x + 2y = -6 in the form of y = mx + b is y = -x - 3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
2x + 2y = -6
Subtract 2x on both sides.
2y = -6 - 2x
Divide both sides by 2.
y = -3 - x
y = -x - 3
This is in the form of y = mx + b
Now,
m = -1 and b = -3.
Thus,
y = -x - 3 is the equation.

A principal randomly chose 40 students from grade 7. Of these students, 9 were wearing watches. Based on this information, what is the most reasonable prediction of the number of students wearing watches in a group of 480 students from grade 7?
Answer:
108 students
Step-by-step explanation:
We can just multiply each value by a k value, or a constant of variation, since we would expect them to be proportional. To find it, we take our two known variables and divide them. 480/40 = 12. Now we multiply that number by 9 to find the projected amount of students wearing watches in the whole grade. 12*9 = 108.

A man bought an item for N5000.00 and sold it at a loss of 25%. How much did he sell it? A. N6250.00 B.N4750.00 C.N3750.00
D. N2250.00
Answer: B. 3750
Step-by-step explanation:
We start by converting the percentage 25% to the decimal 0.25.
Next, we multiply the original price by this decimal (5000*0.25=1250)
And Finally, Since it is a loss we subtract the 1250 from the original price.
5000 - 1250 = 3750
