Peter paid $9.75 to go to the movies, which was $46.25 less than he paid to go to a concert. How much did he pay to go to the concert?
Answer:
$56
Step-by-step explanation:
Simply add the two values together, the algebraic equation would be:
9.75 + 46.25 = 56
So he paid $56 to go to the concert.

Isaac wants to play miniature golf. Go Golf charges $2.50 for ball and club rental and $4.25 per game. Golf Games charges $3.25 for ball and club rental and $8.50 for two games. For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.
The cost would be the same for 47 Go golf and 54 golf games.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
Given data as:
Charges for Go Golf -
Renting a ball and a club costs $2.50.
$4.25 for one game and
Charges for Golf Games -
3.25 for the rental of a ball and a club
$8.50 for two games
We have to determine the number of games would the cost be the same.
Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
For per game = $11.75 / 2 = $5.875
Let the game would be x for Go golf and
And let game would be y for the golf game
As per the given condition,
6.75 x = 5.875y
27/4 x = 47/8 y
Apply cross multiplication operation,
54x = 47y
x/y = 47 / 54
x = 47
So y = 54.
Hence, the cost would be the same for 47 Go golf and 54 golf games.

The cost would be the same for 47 games at Go Golf and 54 games at Golf Games.
Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
Cost per game at Golf Games
= Total charges for 2 games / 2
= $11.75 / 2
= $5.875
Let the number of games be x for Go Golf and y for Golf Games.
As per the given condition,
6.75x = 5.875y
To find the relation between x and y, cross-multiplication can be used:
27/4 x = 47/8 y
54x = 47y
x/y = 47/54
Comparing the value gives
x = 47 and y = 54.
Hence, the cost would be the same for 47 games at Go Golf and 54 games at Golf Games.

determine whether WX and YZ are perpendicular,or, neither W(-7,6),X(-6,9)Y(6,3),Z(3,-6)
Answer: The lines WX and YZ are parallel.
Step-by-step explanation: We are given to check whether the lines WX and YZ are parallel, perpendicular or neither if the co-ordinates of the endpoints of both the lines are
W(3,4), X(5,7), Y(8,2) and Z(6,-1).
We know that the slope of a straight line passing through the points (a, b) and (c, d) is given by
m = d-b/c-a
So, the slope of the line WX is
m1 = 7-4/5-3 = 3/2
and the slope of line YZ is
m2 = -1-2/6-8 = -3/-2 = 3/2
Since , we get m1 = m2, so the two lines WX and YZ are parallel.
Thus, the lines WX and YZ are parallel.
They are not perpendicular, so if you mistyped something and it was parallel that would be the answer, or the answer is neither the mysterious angle form or perpendicular. Hope this helps.

A research team conducted a study showing that approximately 20% of all businessmen who wear ties wear them so tightly that they actually reduce blood flow to the brain, diminishing cerebral functions. At a board meeting of 15 businessmen, all of whom wear ties, what are the following probabilities?
(a) at least one tie is too tight
(b) more than two ties are too tight
(c) no tie is too tight
(d) at least 13 ties are not too tight
Answer:
b) more than two ties are too tight
Step-by-step explanation:
20% of 15
15 = 100%
x = 20%
100x = 15 * 20
x = 300/100
x = 3
ps: I always wear my tie loose at any circumstance, guess I'll never be a good businessman with reduced blood flow to the brain =/

Given f ( x ) = x + 4 and g ( x ) = √ x + 5 , determine the following. Write each answer using interval notation. Domain of f ( g ( x ) ) : Domain of g ( f ( x ) ) :
Answer:
In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.
Step-by-step explanation:
Answer:
The answers are f(g(x))=x−7 and g(f(x))=√x2−7. Explanation: This is a composition of functions. f(x)=x2−4. g(x)=√x−3.

A city's population in the year x = 1990 was y = 2,201,900. In 1994 the population was 2,202,100. Compute the slope of the population growth (or decline)
Answer:
Slope is 50x (50/1)
Explanation:
let m = slope
m = (y2-y1)/(x2-x)
m = (2,202,100-2,201,900)/(1994-1990)
m = 50/1
m = 50

What is comparison of two numbers?
Comparison of two numbers, means to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity.
According to the given question
We have a data in which
Number of people who liked action movie = 78
Number of people who liked action movie = 60
Number of people who disliked the action movie = 22
And, number of people who disliked the drama movie = 40
From the given data we conclude, that action movie is liked by more people as compared to drama movie because 78 > 60.
Hence, the action movie is better received by the audience than the drama.

Find the perimeter of this figure to the nearest hundredth
Answer:
The perimeter of given figure = 56.56 ft
Step-by-step explanation:
Step(i):-
From diagram
The length of the rectangle = 10 ft
The width of the rectangle = 8 ft
Perimeter of the rectangle
= 2 ( l+w)
= 2 ( 10 + 8)
= 2 × 18
= 36
Step(ii):-
The semi circle is included in the given diagram
Now we will find the perimeter of semicircle
We know that
perimeter of the circle
p = 2πr + d
perimeter of the semicircle
P = πr + 2 r (∵ d = 2 r)
Step(iii):-
From diagram the diameter of semicircle is equal to the width of the rectangle
d = 8
d = 2 r = 8
The radius of the circle 'r' = 4
perimeter of the semicircle
P = πr + 2 r
P = 3.14 ( 4) + 8
P= 20.56
Conclusion:-
The perimeter of given figure
= perimeter of rectangle + perimeter of semicircle
= 36 + 20.56
=56.56 ft
