Answer:

  n^2 +n +4

Step-by-step explanation:

Since the divisor has only one term, the quotient is formed by dividing the terms one at a time.

  [tex]\dfrac{4n^4+4n^3+16n^2}{4n^2}=\dfrac{4n^4}{4n^2}+\dfrac{4n^3}{4n^2}+\dfrac{16n^2}{4n^2}=\boxed{n^2 +n +4}[/tex]

__

Your long division tableau will subtract n^2×4n^2 = 4n^4 to form the new dividend 4n^3+16n^2. Then you will subtract n×4n^2 = 4n^3 to get the new dividend of 16n^2. The final quotient term is 4, and you will subtract 4×4n^2 to get a remainder of 0. You will have written the quotient as n^2+n+4.

Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2

Answer:

x = 55

Step-by-step explanation:

To find the value of x

3x - 35 = 130 (vertically opposite angles are equal)

3x = 130 +35

3x = 165

x = 165/3

x = 55

Answer:

x= 55

Step-by-step explanation:

3x-35=130

3x=130+35

3x= 165

x=165/3

x=55

Answer:

No it is not possible, cuz 35 students would need 4.6 teachers, it is not a whole number

Step-by-step explanation:

STUDENT : TEACHER

15 : 2

35 : 4.66

So according to the ratio, if we had 35 students, we would need 4.66 Teachers, but that is not possible, cuz i mean, u obviously can't cut the human into pieces and call that 0.66

Answer:

Step-by-step explanation:

The marked angles at P are a linear pair, so are supplementary:

  (5x +5) +(18x+14) = 180

  23x = 161 . . . . . . . . . . . . . . subtract 19

  x = 7

Those angle measures are ...

  ∠TPQ = (5·7 +5)° = 40°

  ∠TPS = (18·7 +14)° = 140°

__

The marked angle at R is the complement of the acute angle at P, so we have ...

  3y +14 +40 = 90

  3y = 36

  y = 12

  ∠PRS = (3·12 +14)° = 50°

Answer:

To convert fahrenheit to celsius subtract 32 from the fahrenheit number and then multiply it by 5/9!!

1. a. about -17.78 degrees celsius

work: 0-32 = -32 times 5/9

-32*5 = -160

-160/9 = about -17.78

  b. 0 degrees celsius

work: 32-32 = 0

0*5/9 = 0

   c. about 21.11 degrees celsius

work: 70-32 = 38

38*5/9 = about 21.11

   d. 37 degrees celsius

   work: 98.6-32 = 66.6

66.6*5/9 = 37

   e.  about 37.78 degrees celsius

work: 100-32 = 68

68*5/9 = about 37.78

   f. 100 degrees celsius

work: 212-32 = 180

180*5/9 = 100

celsius to fahrenheit is that number times 9/5, then  + 32

2.  (all of these answers are in degrees FAHRENheit. Make sure to write that!)

a. 32

work: 0*9/5 = 0 and 0+32 = 32

b. 89.6

work: 32*9/5 = 57.6.

57.6+32 = 89.6

c. 158

work: 70*9/5 = 126. 126+32 is 158

d.  209.48

work: 98.6*9/5 = 177.48. 177.48+ 32= 209.48

e. 212

work: 100*9/5 = 180. 180 + 32 = 212

f. 413.6

212*9/5 = 381.6. 381.6+32 = 413.6

Answer: 7.83

Step-by-step explanation:

83 over 100 is the same as 83 divided by 100. 83/100 = 0.83

7 + 0.83 = 7.83

Answer:

7.83

Step-by-step explanation:

7 is the whole number

83 is the number that goes to the right of the decimal point

the 100(denominator) shows which place value it should be in, in the decimals place.

A: two observations.

The rest would prove for definite but due to the lack of observations (one case, two observation) this allows us to disprove (most likely) this conclusion.

Answer:

D cos (1/2 x )

Step-by-step explanation:

y = cos (x/2)

because from the graph x = 2pie

= cos pie = -1

The function whose graph is given by; cos (1/2 x )

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x,  the function must be having increasingly output for inputs greater than that value of x.

If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(π) = -1, thus

y = cos (x/2)

because from the graph x = 2π

The function whose graph is given by; cos (1/2 x )

Answer:

Sand: 21 parts.

Lime : 14 parts.

Cement: 7 parts.

Step-by-step explanation:

The number of parts is 3 + 2 + 1 = 6.

So for 42 parts we need:

Sand: 3/6 * 42 = 1/2 * 42 = 21.

Lime:  2/6 * 42 = 1/3 * 42 = 14,

Cement: 1/6 * 42 = 7.
