1 percent of $270 is 2.70 (you just move the decimal point). then multiply your 1 percent by 24 and you have the answer. I get $64.80, doing it on paper.
Add the 24 percent to the original price and you have your retail price: $334.80. If you have a calculator, check my maths.

1) Make 24% as a decimal, which is 0.24.
2) Add 1.0 to 0.24 because it's a mark up to make it 1.24. 
3) Multiply 1.24 with $270 = $334.80.

answer:$334.80

Determine if the columns of the matrix form a linearly independent set. Justify your answer. Choose the correct answer below. A.

kondaur [170]

Th matrix is missing. The matrix is :

$\begin{bmatrix}1 &-4 &4 \\ -4 &16 & 4 \end{bmatrix}$

Solution :

The column of the matrix are $\begin{bmatrix}1\\ -4\end{bmatrix}$ , $\begin{bmatrix}-4\\ 16\end{bmatrix}$ , $\begin{bmatrix}4\\ 4\end{bmatrix}$

Now each of them are vectors in $IR^2$ . But $IR^2$ has dimensions of 2. But there are 3 column vectors, hence they are linearly dependent.

Therefore, the column of the given matrix does not form the $\text{linearly independent set}$ as the set contains $\text{more vectors}$ than there are entries in each vector.

Therefore, option (D) is correct.

Which statement is true?

defon

Answer:

b. Multiplying decimals less than one is finding a part of a part.

Step-by-step explanation:

A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is $\frac{1}{2}$ .

The product of a part and another part can be expressed as;

$\frac{1}{3}$ x $\frac{2}{3}$ = $\frac{2}{9}$

or,

$\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{4}$

or,

$\frac{1}{2}$ x $\frac{2}{3}$ = $\frac{2}{6}$ = $\frac{1}{3}$

The three examples shows: a part x a part.

Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.

I need the answer for 90 please its due tommorow!

babunello [35]

Jacqueline is incorrect.
To find how much trash you can clean in 4 days if you already know how much trash you can clean in one day, multiply 1 2/3 (how much you can clean in one day) by 4.
Another way to write 1 and 2/3 miles is 5/3 (converting a mixed number to a single fraction). Then, 5/3 x 4 = 20/3. (To multiply fractions, just multiply across, leaving 5 x 4 in the numerator and 4 x 1 in the denominator.)
Jacqueline said you would be able to clean 19/3 miles but you can actually clean 20/3.

Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ $\frac{2}{3}$

$=3 \times \frac{3}{2}$
