Suppose the population of a certain city is 4164 thousand. It is expected to decrease to 3460 thousand in 50 years. Find the percent decrease.
Answers
Answer:
16.9%
Step-by-step explanation:
Given data
Initial populatation= 4164
Final population= 3460
Percent decrease= initial-final/initial*100
Percent decrease= 4164-3460/4164*100
Percent decrease= 704/4164*100
Percent decrease= 0.1690*100
Percent decrease= 16.9%
Hence the decrease is 16.9%

Step-by-step explanation:
Let us use sine law to find the length of the yellow cable. Note that a cable of length 64 m is directly opposite the 112° angle and the 58° angle is directly opposite the unknown cable length. We can the set up our sine law as follows:
[tex] \frac{x}{ \sin(58) } = \frac{64 \: m}{ \sin(112) } [/tex]
Solving for x,
[tex]x = \frac{ \sin(58) }{ \sin(112) } \times (64 \: m) = 58.5 \: m[/tex]

sin 60 = √3/2
means perpendicular (p)= √3
and
base (h)=2
find base(b)
using pythagoras theorem
h²=p²+b²
than base (b) will be 1
now
cos 60 =b/h
=1/2
Answer:
cos 60° = 1/2
SohCahToa
Sin = opposite/hypotenuseCos = adjacent/hypotenuseTan = opposite/adjacentsin 60° = opposite / hypotenuse
sin 60° = √3 / 2
The bottom side = √3, the hypotenuse = 2
To find the right side's value, you use Pythagorean's Theorem
a² + b² = c²a² + (√3)² = 2²a² + 3 = 4a² = 4 - 3a² = 1a = 1cos 60° = adjacent/hypotenuse
cos 60° = 1 / 2
What is the diameter of a hemisphere with a volume of 4960\text{ m}^3,4960 m 3 , to the nearest tenth of a meter?
Answers
Answer:
26.6 m
Step-by-step explanation:
The formula for the volume of an hemisphere is given as:
The volume of a hemisphere = (2/3)πr³ cubic units.
Volume = 4960m³
Hence,
4960 = 2/3πr³
4960 = 2 × πr³/3
Cross Multiply
4960 × 3 = 2πr³
Divide both sides by 2π
4960 × 3/2π = 2 πr³/2π
r³ = 2368.2255532
We would cube root both sides.
cube root(r³) = cube root(2368.2255532)
r = 13.329310588 m
Approximately = 13.3m
The formula for diameter = 2 × r
Diameter of the hemisphere = 2 × 13.33m
= 26.6 m
Answer:
26.7 is the right answer.

D: The modal age is 30.
Step-by-step explanation:
A: 8+10+5+7 = 30.
B: 8 + 30 + 32 + 36 = 126
126/4 = 31.5
C: Lowest age is 28 and highest is 36, making that the range for students' ages.
D: The most frequently appearing age in the study is 30, which makes 30 the modal age.

Where,
a = 11

x = ___ units
Answers
Answer:
x = 16 units
Step-by-step explanation:
∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.
If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.
Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.
Since side BC is part of BCD.
Side opposite of 90° [∆BCD] = BC = 32.
Since x is opposite of 30° [∆BCD].
x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.

What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable.
The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
It is given that,
Initial velocity of an object, u = 9 m/s
Height, h = 11 m
The equation that models the height of the object in meters after t seconds is :
[tex]h(t)= -4.9t^2+9t+11[/tex]
We have to find the time it take for the bowling pin to hit the ground
i.e. [tex]-4.9t^2+9t+11=0[/tex]
On solving the above quadratic equation, we get the value of time t is :
t = 2.7 seconds
Hence, The time it takes to hit the ground would be 2.7 seconds.
