Answer:

Julia brother

Step-by-step explanation:

Given that Julia and her brother, Emilio, are both saving to buy a new computer that costs $1,000.

Julia savings per week =100 $

Hence no of weeks required to save full 1000 = 1000/100 = 10

x =10 weeks for Julia

For Julia brother

y=10^{x-2}

When y =1000 we have

1000=10^{x-2}\\x-2=3\\x=5

Hence Julia brother will reach their 1000 goal first in 5 weeks, and Julia in 10 weeks.

If the value of third order determinant is 11. Then what is the value of the determinant formed by its cofactors.
nordsb [41]

Answer:

146.41

Step-by-step explanation:

third order determinant = determinant of 3×3 matrix A

given ∣A∣=11

det (cofactor matrix of A) =set (transpare of cofactor amtrix of A) (transpare does not change the det)

=det(adjacent of A)

{det (cofactor matrix of A)}  ^2  = {det (adjacent of A)} ^2

 

(Using for an n×n det (cofactor matrix of A)=det (A)^n−1 )

we get

det (cofactor matrix of A)^2  = {det(A)  ^3−1 }^2

 

=(11)^2×2  = 11^4

 =146.41

When she checked the answer by estimating, it did not make sense. What error did Janice make?
Leokris [45]
<h2>Answer</h2>

Janice convert a mixed number to the wrong improper fraction

<h2>Explanation</h2>

To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the result to the numerator of the fraction; while keeping the denominator of the fraction as the denominator of the improper fraction.

Let's convert our mixed numbers to improper fractions:

To convert 10\frac{5}{6} we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:

10\frac{5}{6} =\frac{(10*6)+5}{6} =\frac{60+5}{6} =\frac{65}{6}

Now let's convert 1\frac{2}{3}:

1\frac{2}{3}=\frac{(1*3)+2}{3} =\frac{3+2}{3} =\frac{5}{3}

Notice that Janice converted 1\frac{2}{3} as \frac{5}{2}, which is incorrect.

Since 1\frac{2}{3} =\frac{5}{3}, we can conclude that Janice convert a mixed number to the wrong improper fraction.
