Helpppppppppppp plzzzzzzzzzzzzzzzzzzz

ZanzabumX [31]

Answer:

Step-by-step explanation:

$\left[\begin{array}{ccc}7&31\\142&19\end{array}\right]$ = 7(19) - 142(31) = <em>- 4269</em>

$\left[\begin{array}{ccc}7&11&21\\55&-8&2\\-16&-1&-9\end{array}\right]$ = 7(- 8)(- 9) + 11(2)(- 16) + 21(55)(- 1) - 21(- 8)(- 16) - 7(2)(- 1) - 11(55)(- 9) = <em>1768</em>

$\left[\begin{array}{ccc}9.07&6.02&2.01\\-30.7&2.5&3.5\\3.55&-1.1&2.35\end{array}\right]$ = 9.07(2.5)(2.35) + 6.02(3.5)(3.55) + 2.01(- 30.7)(- 1.1) - 2.01(2.5)(3.55) - 9.07(3.5)(- 1.1) - 6.02(- 30.7)(2.35) = <em>647.3561</em>

Fernanda has a collection of 200 seashells from corpus christi she gage her sister one-fifth of her collection how many seashell

Katarina [22]

Answer: 160

Step-by-step explanation: She gave her sister one fifth of the collection; one fifth written as a percent is 20% (I did one and divided it by five). To turn 20% to a decimal I didved by 100 to get 0.20. I multiplied 200 and 0.20 and got 40. 40 is the amount of shells given to her sister, so you would subtract 40 from 200 to find how many shells were left. 200-40=160.

How many years would it take to make $500 interest on a 12000 investment at 3% per year

padilas [110]

Answer:

$t=1.4\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\\ P=\$12,000\\ I=\$500\\r=3\%=3/100=0.03$

substitute in the formula above

$500=12,000(0.03t)$

solve for t

$500=360t$

$t=500/360$

$t=1.4\ years$
