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.
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%

Answer:
(T + S) (x)
Step-by-step explanation:
Cost of manufacturing x T-shirts is T(x) = 4x + 10
Cost of manufacturing x sweatshirts is S(x) = 14x + 19
Total cost of manufacturing x T-shirts and x sweatshirts
= T(x) + S(x])
= (T + S) (x)

Step-by-step explanation:
yes i'm correct
A circus juggler on the highwire gives a bowling pin a final toss into the air with an initial velocity of 9 meters per second from a height of 11 meters. The time taken by the object to hit the ground is 2.7 seconds.
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.

The total length of a road trip was 19.6 hours. If highway signs are posted every 0.07 hours, including one at the end of the road trip, how many highway signs will there be on the road trip?
Answer:
280 highway signs
Step-by-step explanation:
The total length of a road trip was 19.6 hours
Highway signs are posted every 0.07 hours
To find: Number of highway signs
The number of highway signs = total length of a road trip/highway signs
Substituting the values we get,
number of highway signs = 19.6/0.07 = 280
Thus there are 280 highway signs

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?
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.
