a total of 10000 was invested in two business ventures A and B .at the of the first year A and B yielded returns of 6% and 23÷4
wolverine [178]

Answer:

(1)

compound amount = 802.5 $

invest earned = 52.5 $

Step-by-step explanation:

total amount = 10000 $

let amount x invested in ventures A and remaining (1000-x) on ventures B

now,

6x/100 +23/400(1000-x ) = 588.75

{24x+23(1000-x)}/400 =588.75

x=235500-230000

x=5500

Amount invested on A = 5500$

Amount invested on B = 4500$

(2)

principle=750$

time= 1 year

effective invest rate = 7%

a) compound amount = p(1+(r/w)^t

=750{1+(7/100)}^1

=802.5$

b) invest earned = 802.5-700 = 52.5$

Umnica [9.8K]

Answer:

P=19,000(1.034)^{t}

Step-by-step explanation:

Let

P-------> the population of Jacksonville

t----> the number of years since 2018

we know that

The equation that models the population of Jacksonville in t years is

P=19,000(1+r)^{t}

we have

r=3.4\%=3.4/100=0.034

substitute

P=19,000(1+0.034)^{t}

P=19,000(1.034)^{t}

tatiyna
For 10 rows, she takes = 12 min.
So, for 1 row, she'll take = 12/10 

Now, for 15 rows, it would be: 12/10 * 25 = 12/2 * 5 = 60/2 = 30

So, Your Final Answer would be 30 minutes
