In the evening, the temperature is 28 degrees. By midnight it has dropped 31 degrees lower. Between midnight and 4 am it goes do

dalvyx [7]

Answer: 21 degrees

Step-by-step explanation:

In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:

= 28° - 31°

= -3°

Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:

= -3° - 6°

= -9°

Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:

= -9° + 30°

= 21°

Find the projection of v on to w if v = ⟨-5,-2⟩ and w = ⟨1,-1⟩

eduard

Answer:

Step-by-step explanation:

$\frac{\vec v \bullet \vec w}{||\vec w||}\bullet \vec w$

$\vec v \bullet \vec w = \bullet = -5+2 = -3$

$||\vec w ||=\sqrt{2}$

Hence, the result will be

$\frac{-3\sqrt{2} }{2}$

you can put the scalar in to get

Last year, Sally had a gross profit margin of 68% in her hair salon. Her gross profit was $32,508.63. How much did Sally make in

Jlenok [28]

A business' profit margin is the ratio between the gross profit and net sales. It's ideal for a business to have a profit margin closest to 1. For the given situation, Sally has a gross profit of $32, 508.63 and a profit margin of 68% or 0.68. Thus, we have

$0.68 = \frac{32508.63}{sales}$
$sales = \frac{32508.63}{0.68} = 47806.81$

Therefore, the net sales earned by Sally's hair salon is $47, 806.81.

Answer: D. $ 47, 806.81

What is the product of 39 and 5.2 * 10 to the power of 5 expressed in scientific notation?

Vesnalui [34]

The product of 39 and 5.2 x 10 to the power of 5 expressed in scientific notation is $2.028 \times 10^7$

<u>Solution:</u>

Given, expression is product of 39 and 5.2 x 10 to the power of 5

We have to find the product value of above two numbers in the scientific notation,

$\text { Now, product }=39 \times 5.2 \times 10^{5}$

By multiplying 39 with 5.2, we get

$\begin{array}{l}{=2028 \times 10^{5}} \\\\ {=2.028 \times 10^{2} \times 10^{5}} \\\\ {=2.028 \times 10^{2+5}} \\\\ {=2.028 \times 10^{7}}\end{array}$

Hence, the scientific notation of the product is $2.028 \times 10^7$
