Solve the proportion: Men 45 : ? Women 50 : 10​

The average speed of Usain Bolt in meters per second is given as 10.42 meters

The formula for speed is given as distance / time

the distance is said to be 100m

the time as it is written here is said to be 9 3/5

this is written as an improper fraction = 48 / 5

We are to find the average speed in meter per second

speed = 100 / (48/5)

speed = 500 / 48

speed = 125 / 12

write this as a mixed fraction or in decimal

speed = [tex]10\frac{5}{12}[/tex] or 10.42

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.

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

         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.

Answer:

<2 is 50º

Step-by-step explanation:

you first want to find what x is, so you would put the two equations in an (equation)=(equation) and get x and the number across from each other, that would be x=15º. you then plug in the 15 to the equation, and solve that, resulting in 130º. The angle is going to be 180 in total, so subtract the 130º from 180º and you would get 50º

Therefore , the solution of the given problem of NP-complete problem comes out to be that every NP problem is decidable.

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.

Answer:

i have that too bro but i need help with it

Step-by-step explanation:

The equation 2x + 2y = -6 in the form of y = mx + b is y = -x - 3.

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.

Here we have to know that the power of 3 equation is known as cubic equation.

in other terms the polynomial equation which has a degree of three is called a cubic polynomial equation or trinomial polynomial equation.

As we all know that the power of the variable is the maximum up to 3, therefore, we get three values for a variable, say x.

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

From figure A to figure B, the scale factors are 1/8 and 1/2. To scale shapes in various dimensions, utilize the scale factor.

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: 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
