Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Given Information:
Principle amount = P = $6,000
Interest rate = r = 4% = 0.04
Period in years = t = 5
Required Information:
How much interest will he earn in 5 years = ?
Answer:
Amount of interest = $1,299.92
Step-by-step explanation:
Using the formula given in the question,
[tex]B = P(1 + r )^{t}[/tex]
Where B is the final amount, P is the initial amount, r is the interest rate and t is the number of years
[tex]B = P(1 + r )^{t}\\\\B = 6,000(1 + 0.04)^{5}\\\\B = 7,299.92[/tex]
The amount of interest earned is
[tex]Amount \:of\: interest = B - P \\\\Amount \:of \:interest = 7,299.92 - 6,000\\\\Amount \:of \:interest = 1,299.92[/tex]
Therefore, Quincy has earned $1,299.92 in terms of interest by investing $6,000 in a savings account at the rate of 4% annual interest for a period of 5 years.
A bag contains 15 marbles. The probability of randomly selecting a green marble is One-fifth. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is StartFraction 2 over 25 EndFraction. How many blue marbles are in the bag? 2 3 5 6
Answer:
The correct answer is 6.
Step-by-step explanation:
There are "six" blue marbles in the given bag, which is the correct answer would be an option (D).
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Given that bag contains 15 marbles. The probability of randomly selecting a green marble is One-fifth.
The probability of randomly selecting a green marble and then randomly selecting a blue marble is 1/5 x P(blue), where P(blue) is the probability of selecting a blue marble.
As per the question, the probability of this event is 2/25, so we can set up the equation 1/5 x P(blue) = 2/25.
Solving for P(blue), we find that P(blue) = 2/5.
Since the probability of selecting a blue marble is 2/5, and there are 15 marbles in the bag, the number of blue marbles in the bag must be 15 x (2/5) = 6.
Therefore, the number of blue marbles in the bag must be 6.

The Kelvin scale is an absolute temperature scale that can be used to calculate percent change in temperatures. The formula to convert Celsius to Kelvin is K = C + 273.15. What is the percent change if the temperature rises from 21 c to 29 c? Round to the nearest tenrh
The percentage change in temperature is 19.0%.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the temperature rises from 21c to 29c.
The change in temperature is:
29c - 21c
= 4c
The percentage change in temperature from 21c is:
percentage change = (4c/21c)×100
=4/21×100

The price for the jacket is $96. The discount is 31.25%. The sales tax is 9.875%. The expression that represents this situation is Where represents the final price. The first term expresses the initial price. The second term is about the discount which has to be negative. The final term is about the sales tax which must be added to have the total price.
Answer: P = 96 - 30 + 9.48
Step-by-step explanation:
The price of the jacket is $96.
The discount is 31.25% and
The sales tax is 9.875%
To find the price paid, we subtract the discount from the original price and add the sales tax. This will be:
P=96 - (31.25% × 96)+(9.875% × 96)
P = 96 - 0.3125(96) + 0.09875(96)
P = 96 - 30 + 9.48
P = 75.48
Where,
P stands for the final price.
The first term (96) shows the initial price.
The second term (-30) is about the discount which has to be negative.
The final term (+9.48) is about the sales tax which must be added to have the total price.
Two spheres have radii 6 and 15. Find the ratios of the areas and the volumes.
Answer:
1st sphere has r1 = 6
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 6^2 = 144pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 6^3 =288pi
2nd sphere has r1 = 15
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi
=> S1/S2 = 144pi/900pi = 0.16
=> V1/V2 = 288pi/4500pi = 0.064

Matthew is training to participate in a half marathon. Each week, Matthew increases the number of miles he runs in the previous week by the same percent. The table below shows the number of miles he runs in weeks 1 and 2.
Week Number of Miles Run
1 12.5
2 15.5
Complete the sentence. Do not round your answer.
Matthew runs ____ miles in week 3.
Answer:14.58 miles.
Step-by-step explanation:
Matthew is training to participate in a half marathon.
The distance covered by Matthew on the first day is 12.5 miles.
The distance covered by Matthew on the second day is 13.5 miles.
The distance increased on the second day is, 13.5-12.5=1 mile.
The percentage will be,
=\dfrac{1}{12.5}\times 100\%
=0.08\times 100\%
=8\%
Hence, each day he runs 8% more. So the distance covered by him on day 3 will be,
=13.5+\left(13.5\times \dfrac{8}{100}\right)
=13.5+1.08
=14.58 miles

Answer:
Basic consensus is that that other answer is wrong. The actual answer is 19.22
Step-by-step explanation:
To find the common ratio you just do this, last number = 15.5, and first number = 12.5.
15.5/12.5 equals 1.24.
^That's the common ratio.^
using A(n) = a * r ^ n - 1,
you get 12.5 * 1.24 ^ 3 - 1, or just 12.5 * 1.24 ^ 2
and solving that problem, you get 19.22.
Confirm this by doing the same thing earlier, 19.22/15.5 is 1.24. Which is the ratio found earlier. So it checks out.

A company is expanding its building area from 16,500 square feet to 20,460 square feet. What is the percentage increase of the area of the building space?
Answer: 24%
Step-by-step explanation:
A company is expanding its building area from 16,500 square feet to 20,460 square feet. To calculate the percentage increase in the area of the building space, we first find the difference. This will be:
20,460 - 16,500 = 3960
We then divide the difference by the former building area and then multiply by 100. This will be:
3960/16500 × 100
= 0.24 × 100
= 24%
The percentage increase of the area of the building space is 24%.

(6x+4y=43)( 2x-3y=23)
Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )

Magda wants to compare the population density of the two largest countries in the world. She can use this formula. K=P 2.59 M K = population density (people per km2) P = population (millions) M = land area (million square miles) Canada has a population density of 3.57 people per km2 Russia has • a population of 143.96 million • a land area of 6.593 million square miles. Magda thinks that Russia has a greater population density than Canada. Is Magda correct? Show why you think this.
Answer:
Magda is incorrect
Step-by-step explanation:
Given
Formula:
[tex]K = \frac{P}{2.59M}[/tex]
Population Density of Canada = 3.57 people per km²
Population of Russia = 143.96 million
Land Mass of Russia = 6.593 million square miles
Required
Which country has a greater population density.
First, the population density of Russia needs to be calculated using the given formula;
[tex]K = \frac{P}{2.59M}[/tex]
Here, P = 143.96 million
M = 6.593 million square miles
Substitute these values in the above formula;
[tex]K = \frac{143.96}{2.59 * 6.593}[/tex]
[tex]K = \frac{143.96}{17.07587}[/tex]
[tex]K = 8.43[/tex] people per square miles
Before we can make any comparison, we have to convert the unit of K to people per square kilometre.
From unit of standard conversion;
1 square miles = 2.58999 square kilometre
Hence;
[tex]K = \frac{8.43}{2.58999}[/tex]
[tex]K = 3.25483882177[/tex]
[tex]K = 3.25[/tex] people per km²
Given that the Population Density of Canada = 3.57 people per km²
And We solved for the Population Density of Russia = 3.25 people per km²
By Comparison, the Population Density of Canada is greater than the Population Density of Russia;
Hence, Magda is incorrect
