'A' is the square root of 25. That's 5, so take A=5 with you
as you go to the next step.

B is A³.   A³ means (A x A x A).  We know that 'A' is 5, so 'B' is (5x 5 x 5) = 125 .
Take B=125 with you to the next step.

'C' is  B - 25.  We know that  'B'  is 125.  So  C = (125 - 25) = 100 .
Take  C=100  with you to the next step.

'D' is the square root of  'C'.  We know that C=100, so  D = √100 .
The square root of 100 is 10, so  D=10.
Take  D=10  with you to the next step .

'E' is  D+39.  We know that  D=10.  So  E=(10+39) = 49 .
Take  E=49 with you to the last step.

'F' is the square root of 'E'.  We know that E=49.

So square root of 25=a
a could be 5
cube of a=b
5^3=125=b
125-25=c=100
c=100
squareroot of 100=d=10
10+39=e=49
square root of 49=7
F=7


a=5
b=125
c=100
d=10
e=49
f=7

Dividing mixed fractions
Sonbull [250]
A) 2 1/3 = 7/3
   7/3 / 1/4 = 7/3 x 4/1 = 28/3 = 9 and 1/3

b) 4 2/5 = 22/5
   1 1/5 = 6/5
22/5 / 6/5 = 22/5 x 5/6 = 110/30 = 3 and 2/3

Two gears in a machine are aligned by a mark drawn from the center of one gear to the center of the other. If the first gear has
Aleksandr [31]

Answer:

5

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>

the way to get that amount of teeth is

24 = 2 \times 2 \times 2 \times 3 =  {2}^{3}  \times 3

40 = 2 \times 2 \times 2 \times 5 =   {2}^{3}  \times 5

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

{2}^{3} \times 5 \times 3 = 120

120 teeth are 5 revolutions for gear1 and 3 por gear2

The Michigan veteran population in 1990 was 14.2% and in 2000 was 12.4%.
Mandarinka [93]

Let x- intercept represents time

Let y-intercept represents population

Let 1990 represent initial year

Points are (0,14.2)(10,12.4)

slope m= \frac{y2-y1}{x2-x1}

= \frac{12.4-14.2}{10-0} =\frac{-1.8}{10} = -0.08

General linear equation

y= mx+b --------------(i)

here m is slope and b is intercept

plug the 1st point in equation

14.2= -0.018(0) + b

b=14.2

y= 0.018x + 14.2

replace y with p(t) and x with t

p(t) = -0.018t + 14.2
