★ What is 45% of 115?
To find your answer, you need to multiply 45% by 115. To make it easier, you can change 45% to a decimal OR fraction and multiply by 115.
<h2><u>2 WAYS</u></h2><h3>Decimal</h3>
To change a percent to a decimal, all you need to do is remove the percent sign and move the decimal point 2 places to the left.
Now that the percent is changed into a decimal, multiply by 115.
☆ Your answer is 51.75

<h3>Fraction</h3>
Percents are out of 100. You can make a percent into a fraction by making the percent the numerator(top number) and 100 as the denominator(bottom number).
Now that you have changed the percent to a fraction, you can multiply by 115.
![\frac{45}{100} \times 115 = [tex]\frac{5,175}{100} = 51.75](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B100%7D%20%5Ctimes%20115%20%3D%20%5Btex%5D%5Cfrac%7B5%2C175%7D%7B100%7D%20%3D%2051.75)

Answer: Philip can earn back his initial investment in 12.4 years
Step-by-step explanation:
Amount Invested by Philips in period annuity = 800,000
Annual Percentage Rate (APR) = 5.2%
APR compounded monthly for a period of 20 years.
Amount to be received per annuity period = 800,000 * (((1+(0.052/12))^240)*(0.052/12))/(((1+0.052/12))^240)-1)
= 5368.43
Time taken ( in months ) by Philip to earn back his initial investment = 800,000/5368.43 = 149.02 months
Time taken ( in years ) by Philip to earn back his initial investment = 149.02/12 = 12.4 years
Hope it helps.
Thank you :)
Answer: $3.56, since one pound is $2.85, 1/4 is .25 (as a decimal). Then .25x2.85=$0.71+$2.85=$3.56
I hope this helped!
Answer:
A: Exponential
B: Quadratic
C: Linear
Step-by-step explanation:
Let analyse each table
X Y ΔY/ΔX
1 5 xxxxxx
2 11 11 - 5 = 6
3 29 29 - 11 = 18
4 83 83 - 29 = 54
.....................
We can see that, [ ΔY/ΔX ] increases at the fastest rate out of all functions, so it must be exponential function
X Y ΔY/ΔX Δ^2Y/ΔX^2
0 5 xxxxxx xxx
1 7 7 - 5 = 2 xxx
2 13 13 - 7 = 6 6-2 = 4
3 23 23 - 13 = 10 10-6 = 4
..............................
It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values
X Y ΔY/ΔX
3 20 xxxxxx
6 18 2 / 3
9 16 2 / 3
15 12 2 / 3
..............
It is a linear because ΔY/ΔX = 2/3 are constant for all values
