Answer:
413 people should be expected to go to Fiction and Literature
Step-by-step explanation:
Proportion of people who went to Fictions and Literature on Saturday:
342 out of 467 + 433 + 343 = 1243
The proportion is:
342/1243 = 0.275
On Sunday:
Based on Saturday, so 0.275 out of 1500(number of visitors on Sunday).
0.275*1500 = 412.5
Rounding to the nearest whole number:
413 people should be expected to go to Fiction and Literature

Segment AB has endpoints at A ( -3 , 6) and B (7 , -3).
What is the Midpoint of segment AB?
Therefore, the midpoint of segment AB is M (2, 3/2).
The midpoint formula is a method to determine the midpoint of a line segment.
To find the midpoint of a line segment, use the midpoint formula. In this case, the endpoints of the segment are A (-3, 6) and B (7, -3), and we need to find the midpoint.Point M is the midpoint of the segment AB. Let's find the x-coordinate of M first by applying the midpoint formula:
midpoint x-coordinate = (x1 + x2)/2
midpoint x-coordinate = (-3 + 7)/2
midpoint x-coordinate = 4/2
midpoint x-coordinate = 2
Now, let's find the y-coordinate of M by applying the midpoint formula:
midpoint y-coordinate = (y1 + y2)/2
midpoint y-coordinate = (6 + (-3))/2
midpoint y-coordinate = 3/2

Given f(x) = 5^2x,evaluate f (-1), f (0),and f (2)
The values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively
How to evaluate the function?The function is given as:
f(x) = 5^2x
For f(-1), we have x = -1
This gives
f(-1) = 5^(2 * -1)
f(-1) = 0.04
For f(0), we have x = 0
This gives
f(0) = 5^(2 * 0)
f(0) = 1
For f(2), we have x = 2
This gives
f(2) = 5^(2 * 2)
f(2) = 625
Hence, the values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively

What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1
Answer:
x = 1/4
Step-by-step explanation:
-7x - (-5-x) = -9(2x-1) -1
-7x + 5 + x = -18x + 9 - 1
combine like terms:
-6x + 5 = -18x + 8
add 18x to each side of the equation:
12x + 5 = 8
subtract 5 from each side:
12x = 3
divide both sides by 12:
x = 3/12 = 1/4

Cara is flying a kite at the park using a string that is 42 meters long. She notices that the kite is directly above her friend Leah. If Cara and Leah are standing 36 meters apart, how high is the
kite ?
Answer:
21.63 m
Step-by-step explanation:
Given :
Hypotenus = 42 m
Base = 36 m
Hence, using Pythagoras rule :
Opposite = √hypotenus² - Adjacent²
Height = √42²-36²
Height = √1764 - 1296
Height = √468
= 21.63 m
Do the line segments with the given lengths form a right triangle? Drag each set of lengths into the correct box.
Answer:
1) Yes
2)No
3)Yes
Step-by-step explanation:
Use pythagoreans theorem for the first two side lengths and see if it's equal to the third!
Based on the Pythagorean Triple, "9, 40, 41", " will form a right triangle(YES), while "11, 60, 62" and "48, 55, 73" will not (NO).
To find given lengths form a right triangle or not.
What is the Pythagorean Triple?The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:
c² = a² + b².
c is the longest side of the right triangle or largest of the set of integers of the Pythagorean triple.
Thus, find out which set of lengths will form a right triangle:
9, 40, 41 will form a right triangle, because:
41² = 40² + 9²
1,681 = 1,681
Also, the rest set of lengths will not form a right triangle.
Thus, based on the Pythagorean Triple, "9, 40, 41", " will form a right triangle(YES), while "11, 60, 62" and "48, 55, 73" will not (NO).

Answer:
6.28 cm
Step-by-step explanation:
Given,

pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 2 / 2
= 1 cm
Formula : -
Circumference ( circle ) = 2 pi r
2 pi 4
= 2 × 3.14 × 1
= 6.28 cm
Answer:

Using the Addition Method, find the value of x in the
system of equations
3x + 2y = 2
-3x + 5y = 5
Step-by-step explanation:
3x+2y=2------------1
-3x+5y=5-----------2
adding 1 and 2 we get
7y=7
y=1
and from (1),we get
3x+2×1=2
3x=0
x=0 is the required value of x.
We want to solve the given system of equations by using the addition method.
The solution is x = 0.
So we start with the system of equations:
3x + 2y = 2
-3x + 5y = 5
We want to use the addition method, this means that we just add these two equations (left side with left side and right side with right side, in this case) we will get:
(3x + 2y) + (-3x + 5y) = 2 + 5
Now we simplify this to get:
7y = 7
Solving for y, we get:
y = 7/7 = 1
Now that we know the value of y, we can replace it on one of the equations and then find the value of x, let's use the first equation:
3x + 2*1 = 2
3*x = 2 - 2 = 0
x = 0
Then we can conclude that the value of x is 0.
