Answer:

"three times a number is the same as twice the difference of the number and 1"

Step-by-step explanation:

3c is "three times a number"

2(c -1) is "two times the difference of the number and 1"

When writing the description of the right-hand side, one needs to be careful to write it so there is no ambiguity with respect to what is being multiplied by 2. For example, if you say, "two times one less than the number", it is not clear whether that is c -2×1 or 2×(c -1).

A suitable description is ...

three times a number is the same as twice the difference of the number and 1

If a=i+7j+k and b=i+11j+k, find a unit vector with positive first coordinate orthogonal to both a and

Scilla [17]

Take the cross product, then normalize the result.

$\mathbf a\times\mathbf b=\begin{vmatrix}\mathbf i&\mathbf j&\mathbf k\\1&7&1\\1&11&1\end{vmatrix}=-4\,\mathbf i+4\,\mathbf k$

This has norm

$\|\mathbf a\times\mathbf b\|=\sqrt{(-4)^2+4^2}=4\sqrt2$

and so a unit vector orthogonal to both given vectors is

$\dfrac{\mathbf a\times\mathbf b}{\|\mathbf a\times\mathbf b\|}=-\dfrac1{\sqrt2}\,\mathbf i+\dfrac1{\sqrt2}\,\mathbf k$

An equally correct answer would be the negative of this vector, since $\mathbf b\times\mathbf a=-\mathbf a\times\mathbf b$ .

What is the selling price of a set of scrubs if the markup is 80% of the cost, and the cost is $37.99?

attashe74 [19]

Answer:

Discount = Original Price x Discount %/100

Discount = 37.99 × 80/100

Discount = 37.99 x 0.8

You save = $30.39

Final Price = Original Price - Discount

Final Price = 37.99 - 30.392

Final Price = $7.60
