Answer:
Interest rate = 2.41%
Step-by-step explanation:
The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.
The formula to calculate the Interest rate for a Compound Interest is given as:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 12 × [(305.33/240.00)^1/(12)(10) - 1]
r = 0.0240996
Then convert r to R as a percentage
R = r * 100
R = 0.0240996 * 100
R = 2.41%/year
Therefore, the Interest rate = 2.41%
What is the value of the expression 4(x - y) + 2 when x = 7 and y = 1?
Answer:
26
Step-by-step explanation:
4(7-1) +2
4(6) + 2
24+ 2
26
Answer: 26
Step-by-step explanation:
4(x-y)+2
Lets plug in 7 for x and 1 for y
4(7-1)+2=4(6)+2
4*6=24
24+2=26
26 is the answer

Taylor had a bag of 28 marbles. 5 red, 9 blue, 8 yellow, and 6 black. If Taylor pulled out a yellow one and DID NOT put it back in. What is the
probability of pulling out a blue marble (SIMPLIFY YOUR FRACTION).
Blank 1:
Blank 2:
Answer: 1/3
Step-by-step explanation:
Number of red marbles = 5
Number of blue marbles = 9
Number of yellow marbles = 8
Number of and black marbles = 6
Total number of marbles = 28
If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:
= Number of blue marbles / Total marbles
= 9 / 27
= 1/3
The probability of picking a blue marble is 1/3.

A trader bought 12 shirts for $150 altogether. He sold 11 of them for $20 each and one for $10.
Work out his overall percentage profit or loss,
Answer:
53%
Step-by-step explananation:
how much did he sell them for?
11*20 = 220
220+10 = 230
so he got a total of 230 off of buying 150
percent is difference of original
(230-150)/150
80/150
about 53%

The frequency,f kilohertz of a radio wave is inversely proportional to its wavelength, Ym. The frequency of a radio wave that has a wavelength of 3000m is 100 kHz. Find (i) The frequency of a radio wave that has a length of 500m (ii) The wavelength of a radio wave that has a frequency of 800kHz
Step-by-step explanation:
The frequency of a radio wave that has a wavelength of 3000m is 100 kHz
(a) Wavelength = 500 m
We know that,
[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{500}\\\\f=600\ kHz[/tex]
(b) Frequency, f = 800 kHz
[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{800\times 10^3}\\\\\lambda=375\ m[/tex]
Hence, this is the required solution.
A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)
Answer:
The number of customers that would need to come in the café for the company to break even is 470.
Step-by-step explanation:
Given
Revenue = y = 10x ……………….…. (1)
Cost = x = 4,700 + 2x ……………… (2)
Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:
10x = 4,700 + 2x
10x - 2x = 4,700
x = 4,700 / 10
x = 470
Therefore, the number of customers that would need to come in the café for the company to break even is 470.

Sherry and Karl both started their hike with a small bottle filled with water. Tia started her hike with a larger that was 1/2 full. At the end of the hike, Sherry and Tia’s bottles were each half filled with water. Karl’s bottle was filled 1/3 filled with water. Who has the most water left? Construct a math argument to support your answer.
Answer:
The person with the most water left is;
Tia
Step-by-step explanation:
The parameters given in the question are;
The volume of water Sherry and Karl both started their hike with = 1 small bottle each
The volume of water Tia started her hike with = 1/2 of a larger bottle of water
The volume of water Sherry had at the end of the hike = 1/2 of the small bottle of water
The volume of water Tia had at the end of the hike = 1/2 of the large bottle of water
The volume of water Karl had at the end of the hike = 1/3 of the small bottle of water
Let 'x' and 'y' represent the sizes of the bottles of water with Sherry and Karl respectively and let 'Z' represent the size of the bottle of water Tia started the hike with, we have;
The volume water with Tia at the end of the hike = 1/2·x
The volume water with Karl at the end of the hike = 1/2·y
The volume water with Tia at the end of the hike = 1/2·Z
Given;
Z > x
Z > y
∴ 1/2·Z > 1/2·x
1/2·Z > 1/3·y
Therefore, Tia with half of the larger bottle of water at the end of the hike, 1/2·Z has the most water left.
