B)
25
C)
48
D)
100

Answer:

I am pretty sure it is 72, sorry if i'm wrong:)

Step-by-step explanation:

√6= 2.45    6+2.45=8.45  8.45 and 2/3 =9.12  

answer to question 3 is 6+ √6

The fourth one idk if im right or not but im pretty sure its x³ - 12x² + 37x = 0

Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.

Answer:

the answer is C the third one 25,500

Step-by-step explanation:

Answer:

- (x - 4)(x - 11)

Step-by-step explanation:

Given

- x² + 15x - 44 ← factor out - 1 from each term

= - 1 (x² - 15x + 44) ← factor the quadratic

Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)

The factors are - 4 and - 11 , since

- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus

x² - 15x + 44 = (x - 4)(x - 11) and

- x² + 15x - 44 = - (x - 4)(x - 11)

v < −5  or  v > 5

We know either v+8<3 or −8v<−40

Possibility 1

v+8<3

v+8−8<3−8

Subtract 8 from both sides

v<−5

Possibility 2

−8v<−40

−8v  −8  <  −40  −8

Divide both sides by -8

v>5

The population of town A is 4.5 times greater than the population of town B.

The power of a number describes how many times a number is multiplied by itself.

Given are the population of two towns A and B.

Town A has a population of 1.26×10⁵ and the population of town B is 2.8×10⁴.

To find how many times greater is the population of Town A than the population of Town B we have divide the population of town A by the population of town B which is,

= ( 1.26×10⁵)/(2.8×10⁴) times greater.

= (12.6)/(2.8).                                       ( 10⁵ divided by 10⁴ is 10¹ which is 10)

= 4.5 times greater.

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

Step-by-step explanation:

The given statement is the scale factor:

  [tex]\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}[/tex]

This can be rearranged to the formula ...

  [tex]\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}[/tex]

Filling in the given scale distances, you find the actual distances to be ...

  [tex]\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\[/tex]

Answer:

1) = 180 degree reason = being AB is a straight line or supplementary

2) = angle AOB reason = being all the angles are of a straight line AB

3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle

4) = 42 degree

1) fill 180° in the blank

Reason :

Because AOB angles is half a page so it equals 180°

_________________________________

2)fill 180° in the blank

Reason :

AOE + EOF + FOB = AOB

And we have found that AOB angles is half a page so it equals 180°

3) 2x + 34 _ 180°

4) x = 42°

Answer:

-2 =a

Step-by-step explanation:

6-4(a+2)=8+a

Distribute

6 - 4a - 8 = 8+a

Combine like terms

-2 -4a = 8+a

Add 4a to each side

-2-4a+4a=8+a+4a

-2 = 8+5a

Subtract 8 from each side

-2-8 = 8+5a -8

-10 = 5a

Divide each side by 5

-10/5 = 5a/5

-2 =a
