The population of a town is growing uninhibited at a rate of 1% per year. How long would it take the population to double? Round to the nearest tenth.
a. 30.1 years
b. 69.3 years
c. 54.6 years
d. 10.2 years
Answers
Answer:
69.3 years
Step-by-step explanation:
use the equation 2=e^0.01t, then solve for t.
The required time at which the population of the town gets doubled is 69.3 years.
Given that,
The population of a town is growing uninhibited at a rate of 1% per year. how long would it take the population to double is to be determined.
The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
For exponential growth,
the equation is given as,
a = A (1 + 0.01)ˣ
For a = 2A, time x is to be determined,
2A = A (1.01)ˣ
1.01ˣ = 2
x = log2/log1.01
x = 69.3 years
Thus, the required time at which the population of the town gets doubled is 69.3 years.

See
The picture please help test
Answers
Answer:
100.3 sqr. units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of 2 semicircles
✔️Area of parallelogram = base * height
Base = 10
Height = 5
Area of parallelogram = 10*5 = 50 sqr. units
✔️Area of 2 semicircles = 2(½*πr²)
radius (r) = ½*8 = 4
Area of two semicircles = 2(½*π*4²)
Area of two semicircles = π*16 = 50.3 sqr.
✔️Area of composite figure = 50 + 50.3 = 100.3 sqr. units

Total surface area of a cube is 1014cm^2. It's volume will be :

b) 2297 cm^3
c) 2179 cm^3
d) 2117 cm^3
plz answer...if you answer with explanation i will surely follow you and rate 5
Answers
Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
Total Surface Area = 6a² Volume = a³_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,
[tex]6a^{2} =1014[/tex]
[tex]=> a^{2} =\frac{1014}{6} = 169[/tex]
[tex]=> a = \sqrt{169} = +13 \: or -13[/tex]
But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³
8. A haircut is $120, how much is a 15% tip? *
Answers
Answer:
18
Step-by-step explanation: 120 times 0.15
Answer:
$18
Step-by-step explanation:
To work out 15% using a calculator:
0.15 multiplied by 120 which is 18
To work out 15% without a calculator:
10% of 120 is 12. (Just remove the last number whenever you want to get 10% or add it on as a decimal if it's greater than 0. e.g. 10% of 40 is 4 but 10% of 48 is 4.8)
To add the 5% divide 12 by 2 which is 6.
Add the 10% to the 5% to get the 15%.
12+6=18

M is directly proportional to r squared when r=2, m=14
Workout the value of r when M =224
Answers
Answer:
r = 8
Step-by-step explanation:
Given that M is directly proportional to r² then the equation relating them is
M = kr² ← k is the constant of proportionality
To find k use the condition when r = 2 , M = 14
k = [tex]\frac{m}{r^{2} }[/tex] =[tex]\frac{14}{4}[/tex] = [tex]\frac{7}{2}[/tex]
M = r² ← equation of proportion
When M = 224, then
224 =[tex]\frac{7}{2}[/tex]r² ← multiply both sides by 2
7r² = 448 ( divide both sides by 7 )
r² = 64 ( take the square root of both sides )
r = [tex]\sqrt{64}[/tex] = 8

Step-by-step explanation:

btw, plz brainliestt :))
The value of t is 14
Given the algebraic equation:
[tex]42 + 5t = 8t\\[/tex]
To find the value of t in the algebraic equation given, we would apply the some of the laws of equalities or properties as follows:
[tex]42 + 5t - 5t = 8t - 5t[/tex] (subtraction property of equality)
[tex]42 = 3t\\\frac{42}{3} = \frac{3t}{3}[/tex] (division property of equality)
[tex]14 = t[/tex]
[tex]t = 14[/tex]
Therefore, the value of t is 14.

A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 74.46 cm long. 1/360th of the circumference of the circle is 0.51 cm long. What is the measure of this angle in degrees?
________degrees
Answers
Answer:
146°
Step-by-step explanation:
You're given an angle, where the vertex is the center of a circle. This makes the angle's rays two radii of the circle. You are then given the length of 1/360th of the circle, which is .51cm, which is also 1 degree of the circle.
If the arc of the circle between the angle's rays is 74.46 cm. It becomes a division problem:
[tex]\frac{74.46 cm}{.51 cm}[/tex]
After the division, the fraction simplifies to 146, which is 146 segments of .51cm in the arc, and since .51cm is equivalent to 1 degree of the circle, the arc is 146 degrees.
Determine whether the variable is qualitative or quantitative. Explain your reasoning. The price of a new computer.
Answers
Answer:
The price of a new computer is quantitative.
Step-by-step explanation:
A variable can be classified as qualitative or quantitative.
Qualitative:
When the possible values of the variables are labels, for example, good or bad, yes or no,...
Quantitative:
When the possible values of the variables are numbers, for example 1, 2, 1000,....
In this question:
The price of a computer is a numeric value, so it is a quantitative variable.
"The price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.
What are Qualitative and Quantitative Variables?Quantitative variables are variables whose values are numerical or measured. Example of a quantitative variable is number of students in a given class.Qualitative variables do not have numerical value or are not measurement variables. An example of a qualitative variable is eye color.Therefore, "the price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.
