See explanations below
Step-by-step explanation:
Example of how to find the determinant of a 2×2 matrices is as shown;
![\left[\begin{array}{ccc}a&b\\c&d&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%26%5Cend%7Barray%7D%5Cright%5D)
= (a*d)-(b*c)
= ad - bc
Applying this to solve the given questions
1) (3*4) - (-3*-1)
= 12 - (3)
= 9
2) (-12*5)-(-1*12)
= -60 - (-12)
= -60+12
= -48
3) (0*4)-(-1*17)
= 0-(-17)
= 0+17
= 17
4) (8*-1)-(-4*-1)
= -8-(4)
= -8-4
= -12
5) (2*-1)-(2*-1)
= -2-(-2)
= -2+2
= 0
6) 1(1) - 0(0)
= 1 - 0
= 1
Express 0.9534 as a fraction
<span>0.9534 × 10 × 10 × 10 × 10 = 9534
</span><span>1 × 10 × 10 × 10 × 10 = 10000
</span>9534/10000
Divide by GCF:-
GCF = 2
9534 ÷ 2 = 4767
1000 ÷ 2 = 500
4767/500
^^^Improper fraction
Convert to mixed number:-
4767 ÷ 500 = <span>9.534
500 × 9 = 4500</span>
<span>4767 - 4500 = 267</span>
<span>9 = whole number</span>
<span>267 = </span>numerator
<span>500 = </span>denominator
<span>
9 267/500
0.9534 = 9537/10000 = 4767/1000 = 9 267/500 </span><span />
$20 a week for 10 weeks is:
20*10 = $200
She spends $6.75 each day for 5 days:
6.75*5 = $33.75.
Lets subtract her spending from her savings to find out how much she has left:
$200-$33.75 = $166.25
