Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)

In 2014, the population of China was 1.39 billion. Compare China’s 2014 population to the world population with a ratio. Write your answer as a fraction, and as a percent rounded to 1 decimal place
Fraction ?
percent?
Answer:
Percentage of china's population to world = 19.85 % (Approx.)
Step-by-step explanation:
Given:
Population of China shows in 2014 = 1.39 billion
Find:
Fraction of china's population to world
Percentage of china's population to world
Computation:
Approximately population of world = 7 billion
Fraction of china's population to world = 1.39 / 7
Percentage of china's population to world = [1.39 / 7]100
Percentage of china's population to world = [0.1985]100
Percentage of china's population to world = 19.85 % (Approx.)

The first student opened every locker. The second student went to every second locker and closed it. The third student went to every third locker and changed it (i.e. if the locker was open, the student closed it; if the locker was closed, the student opened it). In a similar manner, the fourth, fifth, sixth, . . . student changed every fourth, fifth, sixth, . . . locker. After all 50 students had passed by the lockers, which lockers were left open?

A helicopter is told taht there is another helicopter 300 feet below at 76°angle of depression. Approximately how far apart are the helicopters? Round to the nearest foot
Answer: [tex]309\ ft[/tex]
Step-by-step explanation:
Given
Vertical distance between two helicopters is 300 ft
angle of depression is [tex]76^{\circ}[/tex]
Suppose the distance between the helicopters is d
from the figure, we can write
[tex]\Rightarrow \sin 76^{\circ}=\dfrac{300}{d}\\\\\Rightarrow d=\dfrac{300}{\sin 76^{\circ}}\\\\\Rightarrow d=309.18\approx 309\ ft[/tex]
The distance from the helicopter from the another helicopter which is 300 feet below is 309 ft.
What is angle of depression?The angle of depression is the angle made between the straight line and the line of observer seeing the object, which is below that straight line.
A helicopter is told that there is another helicopter 300 feet. Hence the vertical distance between two helicopters is 300 ft.
The angle of depression from the helicopter which is a height below to the another helicopter is 76°.
The image of the given situation is attached below. Let suppose the distance between them is x meter. Then from the trigonometry the sine angle can be given as,
[tex]\sin(76)=\dfrac{300}{x}\\x\approx 309\rm\; ft[/tex]
Hence, the distance from the helicopter from the another helicopter which is 300 feet below is 309 ft.

The characteristic or value of a population that is under consideration is
called a(n)_____
parameter.
Answer: Population Parameter
The characteristic or value of a population that is under consideration is called a parameter, which represents a numerical summary of the population's attributes or features.
The characteristic or value of a population that is under consideration is called a parameter.
In statistics, a parameter refers to a numerical value that describes a specific characteristic of a population.
It is often used to make inferences or draw conclusions about the entire population based on a sample.
Parameters can include measures such as the population mean, population standard deviation, population proportion, or any other characteristic that helps describe the population of interest.
It is important to distinguish parameters from statistics, which are the corresponding values calculated from a sample and used to estimate or infer the population parameters.

Math help please show work
Answer:
Step-by-step explanation:
To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.
To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.
solve the equation algebraically please help i don’t understand!!
Hi there!
[tex]\large\boxed{(0, -1)}[/tex]
-2x + 8y = -8
2x - 3y = 3
We must eliminate a variable to solve. We can add the two equations to eliminate x because -2 + 2 = 0:
-2x + 8y = -8
2x - 3y = 3
-----------------
0x + 5y = -5
5y = -5
y = -1
Substitute this value of y into an equation to solve for x:
-2x + 8(-1) = -8
-2x -8 = -8
x = 0
Thus, the solution of this system is:
(0, -1)
Answer:
(0,-1)
Step-by-step explanation:
Hi there!
We are given the system:
-2x+8y=-8
2x-3y=3
there are 3 ways to solve systems of equations: graphing, substitution, and elimination
let's solve this system by elimination, which we will add the 2 equations together to clear one variable, solve for the other variable, and plug the value of that variable to solve for the variable that was cleared earlier.
add the two equations together (-2x and 2x clear out to equal 0 and we'll have only y left.)
-2x+8y=-8
+
2x - 3y= 3
_________
5y=-5
divide by 5 on both sides
y=-1
now substitute y as -1 into one of the equations to solve for x
for example, we can do the second equation
2x-3(-1)=3
multiply
2x+3=3
subtract 3 from both sides
2x=0
divide by 2
x=0
therefore the answer is x=0, y=-1. If you need it as a point, it's (0,-1)

please help asap I will give you 15 points. no links or ill report you
Answer:
Step-by-step explanation:
Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is
R = (-∞, 3] or another way to state this is
R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".

Answer:
The reasoning here is that the price should be based on the volume.
for a cylinder it's pi * r² * height
for a cone it's 1/3 * pi * r² * height
you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.
so a fair price should be 70ct, ignoring packaging of course.

At a track and field event, a thrower releases the hammer using one full rotation that takes 2.5 seconds. What is the angular velocity in units of radians per second?
Enter your answer as a value rounded to the nearest hundredth, like this: 0.35
Answer:
[tex]2.51\:\mathrm{rad/s}[/tex]
Step-by-step explanation:
Angular speed is given by [tex]\omega=\frac{\Delta \theta}{\Delta t}[/tex], where [tex]\Delta \theta[/tex] is angle change in radians and [tex]\Delta t[/tex] is elapsed time.
Since the hammer makes one full rotation in 2.5 seconds, it is travelling 360 degrees or [tex]2\pi[/tex] radians every 2.5 seconds.
Thus, we have:
[tex]\omega=\frac{2\pi}{2.5}\approx \boxed{2.51\:\mathrm{rad/s}}[/tex]
. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

A carpenter has two pieces of wood. He wants to find the density of each piece.
The first piece came from a birch tree. The piece of birch wood measures 2 meters by 4 meters by 3 meters and weighs (mass) 16 kilograms.
The second piece came from a cypress tree. The piece of cypress wood measures 3 meters by 5 meters by 2 meters and weighs (mass) 15.3 kilograms.
Which piece of wood has a greater density?
Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.
