Evan volunteers on the weekend at the Central Library. As a school project, he decides to record how many people visit the library, and where they go. On Saturday, 433 people went to The Youth Wing, 335 people went to Social Issues, and 367 went to Fiction and Literature.
On Sunday, the library had 600 total visitors. Based on what Evan had recorded on Saturday, about how many people should be expected to go to Fiction and Literature? Round your answer to the nearest whole number.
Answer: Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.
Step-by-step explanation:
To estimate how many people to expect in the Fiction and Literature section on Sunday, we can assume that the proportion of visitors to each section remains the same as it was on Saturday.
First, we need to calculate the total number of visitors on Saturday:
433 (Youth Wing) + 335 (Social Issues) + 367 (Fiction and Literature) = 1135
Next, we can find the proportion of visitors to the Fiction and Literature section:
367 (Fiction and Literature) / 1135 (total visitors on Saturday) ≈ 0.323
We can use this proportion to estimate the number of visitors to the Fiction and Literature section on Sunday:
0.323 (proportion of visitors to Fiction and Literature) x 600 (total visitors on Sunday) ≈ 194
Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.
Q3. Find the surface area of this cuboid 5 cm 6 cm 10 cm
Answer:
The total surface area of the cuboid is 280.
Length: 5 cm

Total Surface Area of Cuboid = 2*((Length of Cuboid*Height of Cuboid)+(Height of Cuboid*Width of Cuboid)+(Length of Cuboid*Width of Cuboid))
SATotal = 2*((l*h)+(h*w)+(l*w)) --> 2*((5*6)+(6*10)+(5*10))
SATotal = 280
A system of equations is shown below.
y=2/3x−5
y=1/2x+3
How many solutions does the system have?
A.2 solutions
B.no solutions
C.infinite solutions
D.1 solution
The solution to the system is (x,y) = (48,19).
To find the solutions to the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the two expressions for y equal to each other and solve for x:
2/3x−5 = 1/2x+3
Multiplying both sides by 6 (the least common multiple of 3 and 2) to clear the fractions, we get:
4x - 30 = 3x + 18
Simplifying, we get:
x = 48
Now that we know x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:
y = 2/3(48) - 5 = 19
So the solution to the system is (x,y) = (48,19).
Since there is exactly one solution, the answer is (D) 1 solution.

Given: cos(theta) = 0,6 ; 270° < theta < 360°
Find: 1) sin2(theta)
2) cos2(theta)
3) tan4(theta)
Additional tools usage solving this question is prohibited
Step-by-step explanation:
[tex] \sin(2 \alpha ) = 2 \sin( \alpha ) \cos( \alpha ) [/tex]
To find sin(a),
[tex] \sin( \alpha ) = \sqrt{1 - \cos {}^{2} ( \alpha ) } [/tex]
[tex] \sin( \alpha ) = \sqrt{1 - (0.6) {}^{2} } [/tex]
[tex] \sin( \alpha ) = \sqrt{0.64} [/tex]
Since sin is negative in the interval (270,360)
[tex] \sin( \alpha ) = - 0.8[/tex]
Now we can find sin(2a)
[tex]2( - 0.8)(0.6) = - 0.96[/tex]
2. The identity for cos(2x) is
[tex]2 \cos {}^{2} (x) - 1[/tex]
We know cos x is 0.6 so we get
[tex]2(0.6) {}^{2} - 1 = - 0.28[/tex]
part 3:
[tex] \tan(4x) = \frac{2 \tan(2x) }{1 - \tan {}^{2} (2x) } [/tex]
[tex] \tan(2x) = \frac{ \sin( 2x) ) }{ \cos(2x) } = \frac{ - 0.96}{ - 0.28} = 24[/tex]
So we end up getting,
[tex] \tan(4x) = \frac{2(24)}{1 - (24) {}^{2} } [/tex]
[tex] \tan(4x) = \frac{48}{1 - 576} [/tex]
[tex] \tan(4x) = - \frac{48}{575} [/tex]

Find the numbers of bags of potting soil that a company can produce for seedlings, general potting, and hardwood plants with the given amounts of raw materials. The raw materials used in one bag of each type of potting soil are shown below.
Sand Loam Peat Moss
Seedlings 2 units 1 unit 1 unit
General 1 unit 2 units 1 unit
Hardwoods 2 units 2 units 2 units
450 units of sand
450 units of loam
360 units of peat moss
Company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants. The solution has been obtained by using linear equation.
What is a linear equation?
The degree of the linear equation is 1. It is very clear that linear equations with exponents greater than one lack variables. The equation for this graph yields a straight line.
Let S be the bags of seedlings, G be for general potting, and H be for hardwood plants.
It is given that each bag of seedling soil needs 2 units of sand, each bag of general soil needs 1 unit of sand, and each bag of hardwood soil needs 2 units of sand. We have 450 units of sand.
So, from this we get
2S + G + 2H = 450 ...(1)
Similarly, for units of loam and peat moss, we get the equations as
S + 2G + 2H = 450 ...(2)
S + G + 2H = 360 ...(3)
Now, on subtracting (3) from (2), we get
G = 110
On substituting this, we get
2S + 2H = 360 ...(4)
S + 2H = 230 ...(5)
S + 2H = 250 ...(6)
Now, we subtract (2) from (1), we get
S = 130
On substituting this in equation (5), we get
130 + 2H = 230
2H = 100
H = 50
Hence, company can produce 130 bags of seedlings, 110 bags of general plotting and 50 bags of hardwood plants.

What is the binary conversion of 2?
The binary conversion of 2 is 10.
In binary, there are only two possible digits, 0 and 1. Each digit in a binary number represents a power of 2, with the rightmost digit representing 2^0 (which is 1), the second digit representing 2^1 (which is 2), the third digit representing 2^2 (which is 4), and so on.
So in the binary number 10, the rightmost digit represents 2^0, which is 1, and the second digit represents 2^1, which is 2. Adding these two powers of 2 together gives a total value of 2 in binary.
To convert a decimal number to binary, you can divide the number by 2 and record the remainder at each step until the quotient is 0. Then, the binary number is simply the remainders read in reverse order. In this case, 2 divided by 2 is 1 with a remainder of 0, so the first digit of the binary number is 0. 1 divided by 2 is 0 with a remainder of 1, so the second digit of the binary number is 1. Therefore, the binary conversion of 2 is 10.

Anita bought her phone one year ago for $400, and she wants to eventually sell it to help pay for an upgrade. She checked the manufacturer's website and found that her phone is currently valued at $308, and it will continue to depreciate each year.
Write an exponential equation in the form y - a(b)* that can model the value of Anita's phone, y, × years after purchase.
Use whole numbers, decimals, or simplified fractions for the values of a and b.
Answer:
y= 400(0.77)^x
Step-by-step explanation:
The value decreases by 23% from,400 to 308 in 1 year. so if this continues then the equation would be y=400(0.77)^x.
The 0.77 comes from decaying 23%, meaning 1-0.23 = 0.77

The correct answer as per the video that demonstrates the Monty Hall Problem is option C. 20. That is how many times the men perform each strategy A and B.
Goats can be found behind two curtains and one behind each door.
Anytime a contestant selects a curtain, one of the certain to curtains informs the contestant that a goat was hiding behind all of this.
The contestant must choose one of two curtains, one of which has a car in it and the other of which has a goat on it. Therefore, there is an equal chance of. choosing either a goat or a car.
Similar to that, provided.
Probability A for strategies and tactics is 10%, or 2 out of every 20 trials.
80% of Strategy B's chance is equal to 16 accomplishments spread across 20 directions.
Thus,
16 success = 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success
Taking the common factor,
16 success = 8 (2 success)

Jade was 416 meters above the ground when she deployed her canopy.
What is kinematics?
kinematics, specifically the equation of motion for constant velocity, to solve the problem of finding the height above the ground when a person deploys their canopy while descending.
We can use the formula:
height = rate x time
To determine how high Jade was above the ground when she deployed her canopy. Let's denote the height she was at when she deployed her canopy as "h".
From the given information, we know that Jade descended at a constant rate of 40 meters every 5 seconds, so her rate of descent is 40/5 = 8 meters per second.
We also know that it took her exactly 57 seconds to reach the ground. Therefore, the time she spent descending with her canopy deployed is 57 - 5 = 52 seconds.
Using the formula, we can write:
h = 8 x 52
Simplifying this equation gives us:
h = 416
Hence, Jade was 416 meters above the ground when she deployed her canopy.

30°
Write your answer in simplest radical form.
kilometers
Answer:
4√3 or 6.9282Km
Step-by-step explanation:
Let the triangle be ABC, right angled at B
Angle A = 60 degrees
Angle C = 30 degrees
BC = 6 km
To find AB,
Tan30°=AB/BC
Now we know that tan30° is 1/√3 so,
1/√3 = AB / 6
6/√3 = AB
6√3/3 =AB
2√3 = AB
Now we have the value of two sides so we can use the Pythagoras Theorem to find the hypotenuse, which is g
AB² + BC² = AC²
(2√3)² + 6² = g²
12 + 36 = g²
48 = g²
Therefore g = √48km or 4√3km or 6.9282Km
