This is probably wrong, but from what I know, there are 16 vertices, 24 edges, and 10 faces. I’m not sure if this is wrong, but I did some math and some research, and this is what I got.

Question 4

skelet666 [1.2K]

Answer:

See explanation

Step-by-step explanation:

You forgot to give the coordinates of C.

Note that, the mapping for 90° clockwise rotation around the origin is given by:

$(x,y)\to (-y,x)$

Assuming the coordinates of C were (-6,6), then the coordinates of C after a 90° clockwise rotation

around the origin is (-6,-6)

Please help me with this question step by step on how to solve it. It takes the earth 24 h to complete a full rotation. If it wo

pav-90 [236]

In order to find the number of hours it takes to do the full rotation we separate into pieces the days, hours, and minutes and convert each of them separately.

using the conversion factor from days to hours we get that

$1\text{day}=24\text{hours}$

then we get that

$38\text{days}\cdot\frac{24\text{hours}}{1day}=912hours$

hours does not need a conversion factor, meaning that

$10\text{hours}=10\text{hours}$

continue by converting the minutes using the following conversion factor

$1\text{hour}=60\min$

then,

$30\min \cdot\frac{1\text{hour}}{60\min }=0.5\text{hours}$

To complete add all the results together

$\begin{gathered} 912+10+0.5 \\ 922.5\text{hours} \end{gathered}$

It takes mercury 922.5 hours to complete a full rotation.

Five less than twice a number is equal to 57

Sliva [168]

The easiest way to do this is to break it down and translate it before solving. Start with twice a number, if you use n to represent eh number, you will have 2n. Then, add the 'less than' part. 'Five less than' means that five is being subtracted from the next part, which is 2n. Now you have 2n - 5. The last translation is simple, 'equal to 57' will complete the equation as 2n - 5 = 57.
If you want to solve the equation, use the Order of Operations.

2n - 5 = 57 Add 5 to both sides
2n = 62 Divide both sides by 2
n = 31
