Answer:
28*4/7
Step-by-step explanation:
4/7
the 7 represents the 28. 28 is a multiple of 7.
<u>28</u> * <u>4</u> = <u>112</u> = 16
1 7 7
<u><em>there are 16 girls</em></u>
also we know 4*7=28 so if we count the multiples of 4, there is 4 8 12 and the 4th multiple is 16.
<u><em /></u>
Answer:
2 and 8
1 and 3
Step-by-step explanation:
statement a+b < a*b
-2 + -8 < -2 * -8 => -10 < 16 TRUE
-1 + -3 < -1 * -3 => -4 < 3 TRUE
1+3 < 1*3 => 4 < 3 FALSE
2 + 8 < 2 * 8 => 10 < 16 FALSE
A is 11 and b is 16. for b you would plug in what you got for a for x
Answer:
Amount he must have in his account today is $5,617.92
Step-by-step explanation:
Data provided in the question:
Regular withdraw amount = $900
Average annual interest rate, i = 4% = 0.04
Time, n = 7 years
Now,
Present Value = ![C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)](https://tex.z-dn.net/?f=C%20%5Ctimes%5Cleft%5B%20%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%20%5Cright%5D%20%5Ctimes%281%20%2B%20i%29)
here,
C = Regular withdraw amount
Thus,
Present Value = ![C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)](https://tex.z-dn.net/?f=C%20%5Ctimes%5Cleft%5B%20%5Cfrac%7B1-%281%2Bi%29%5E%7B-n%7D%7D%7Bi%7D%20%5Cright%5D%20%5Ctimes%281%20%2B%20i%29)
Present Value = ![900 \times\left[ \frac{1-(1+0.04)^{-7}}{ 0.04 } \right] \times(1 + 0.04)](https://tex.z-dn.net/?f=900%20%5Ctimes%5Cleft%5B%20%5Cfrac%7B1-%281%2B0.04%29%5E%7B-7%7D%7D%7B%200.04%20%7D%20%5Cright%5D%20%5Ctimes%281%20%2B%200.04%29)
Present Value =
Present Value =
Present Value = 936 × 6.00205
or
Present Value = $5,617.92
Hence,
Amount he must have in his account today is $5,617.92
