Answer:
The answer is 40
Step-by-step explanation:
28/x=7/10
firs you need to setup this equation and solve it to get 40
there are 12 girls in the band and 28 boys in the band and I know this because 12+28=40 just like 3/10 + 7/10= 10/10
12 divided by 4 is 3
28 divided by 4 is 7
The principal value is $150.
We have the following values -
rate of interest - 4%
Time period = 6 months = 0.5 year
Simple interest = $36
We have to find the principal value.
<h3>What is the formula to calculate the Simple Interest for a Principal amount of $P at a rate of r% per annum for time of t years?</h3>
The simple interest can be calculated using the formula -
S.I. = ![\frac{P\times r\times t}{100} \\](https://tex.z-dn.net/?f=%5Cfrac%7BP%5Ctimes%20r%5Ctimes%20t%7D%7B100%7D%20%5C%5C)
The above expression can be written in terms of principal value as -
![P = \frac{100\times S.I.}{r\times t}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B100%5Ctimes%20S.I.%7D%7Br%5Ctimes%20t%7D)
We can use the above formula in the question given - Using the formula for principal value we get -
P = ![\frac{100 \times36}{4\times 0.5}](https://tex.z-dn.net/?f=%5Cfrac%7B100%20%5Ctimes36%7D%7B4%5Ctimes%200.5%7D)
P = ![\frac{3600}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3600%7D%7B2%7D)
P = $1800
Hence, the principal value is $150.

Answer: 6
Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6

im not sure how to solve that sorry
Add all the numbers up but pay attention you are counting 6.30 twice. then you divide by the numbers of days you have.(5)
<span>Your answer should be 5.47</span>
