Can anyone explain to me me how long division works briefly or in detail? For 20pts?
KIM [24]
If you have 1275 ÷ 4, you write it as shown, with 1275 on the inside and 4 on the outside. then you go digit by digit and find how many times 4 goes into the number. it goes into 1 zero times, so an imaginary 0 is put in the first spot above the 1. next, 4 goes into 12 three times, so 3 is written above the 2. After that, subtract 4×3 from 12, which leaves 0, and bring down the 7. 4 goes into 7 once with a remainder of 3, so a 1 is put up top and the 5 brought down next to the three. 4 goes into 35 eight times with a remainder of 3,so 8 is written up top. the 3 is the remainder, written as R3. so your answer is 1274÷4= 318 R3.
Hope this helps.

Graph the image of Kite BCDE after a translation 5 units down.​
NeTakaya

Answer:

See attachment for the translated kite

<em></em>

Step-by-step explanation:

Given

The attached image of BCDE

Required

Translate 5 units down

From the attachment;

B = (-7,0)

C = (0,5)

D =(-7,10)

E = (-10,5)

The rule to translate 5 units down is:

(x,y) \to (x,y-5)

So:

B' = (-7,-5)

C' = (0,0)

D' = (-7,5)

E' = (-10,0)

How can you use scientific notation to compare the mass of an electron to the mass of a proton
Advocard [28]

Answer:

explained below

Step-by-step explanation:

Because the electro has a smaller mass than the mass of the proton, scientific notation is usually used so that the numbers are on the same "scale" but if we see the scientific notation we may be able to identify which is greater and which is less, due to that the exponent is less the number is smaller and on the contrary if the number is greater, it is a larger number.

In the image I leave an example of the use of scientific notation in this area

If f(x) = −2 + 8, what is f(−1.8)?
pashok25 [27]
As the question is written,
.. f(-1.8) = -2 +8 = 6

We suspect x is missing. Perhaps you intend
.. f(x) = -2x +8
.. f(-1.8) = -2(-1.8) +8 = 11.6
