Answer:

  $94,473.31

Step-by-step explanation:

The multiplier in 25 years is ...

  e^(rt) = e^(0.03·25) = e^0.75 ≈ 2.117

To have an account value of $200,000 in 25 years, you need to deposit now ...

  $200,000/2.117 = $94,473.31

_____

When this amount is multiplied by 2.117, the result is 200,000.

Answer:

6

Step-by-step explanation:

Answer:

The area is 6 because i add it and the divide it

25% = 25/100

25% of 28 is 7

~fractions

=====================

understand the steps below!

7 ÷ 25%

= 7 ÷ 25/100

= 7 × 100/25

= 7 × 4

= 28 ✔️

Answer:

[tex]x=\frac{9}{4}[/tex]

Step-by-step explanation:

Answer:

[tex]\boxed{\boxed{\sf x=\frac{9}{4} }\:\sf or \:\boxed{x=2.25}}[/tex]

Step-by-step explanation:

[tex]\sf \cfrac{1}{2}\:x+\cfrac{3}{4}=\:x\cfrac{5}{6}[/tex]

Subtract x (5/6) from both sides:

[tex]\longmapsto\sf \cfrac{1}{2}\: x+\cfrac{3}{4} -x\left(\cfrac{5}{6}\right)=0[/tex]

Subtract 3/4 from both sides:

** Anything subtracted from zero gives its negation.**

[tex]\longmapsto\sf -\cfrac{1}{3}\:x=-\cfrac{3}{4}[/tex]

Multiply both sides by -3, reciprocal of - 1/3

[tex]\longmapsto\sf x=-\cfrac{3}{4} (-3)[/tex]

Express - 3/4 (-3) as single fraction:

[tex]\longmapsto\sf x=\cfrac{-3(-3)}{4}[/tex]

Multiply -3 and -3 = 9

[tex]\longmapsto\sf x= \cfrac{9}{4}[/tex]

Answer:

The second one : x + 90 + 61 = 180

Step-by-step explanation:

I hope this helps!

Let me know if you need the explanation.

Answer:

hmmmmm

Step-by-step explanation:

Step-by-step explanation:

very simple thought experiment :

he is going 90 km/h (90 kilometers per hour), so, he moving 90 km in 1 hour.

how far is he going in just 2 seconds ?

so, we get two ratios.

90km/1 hour = 90,000 meter / 1 hour

x meter / 2 seconds

we need to bring both ratios (they are fractions) to the same dimension of the denominators, so that we can then bring them to the same denominator.

the first is dealing with an hour.

the second one with (2) seconds.

so, how many seconds are in 1 hour ?

60 seconds per minute, 60 minutes in the hour.

60×60 = 3600 seconds.

so, now we know, the first ratio is also

90,000 meter / 3600 seconds

now we need the factor to to multiply numerator and denominator with to bring 3600 down to 2.

3600 × f = 2

f = 2/3600 = 1/1800

now we get

90,000 / 3600 × (1/1800) / (1/1800) =

(90000 / 1800) / (3600 / 1800) = 50 / 2

so, 90km/h is the same speed as 50 meter / 2 seconds.

and therefore we know, the building was 50 meters long.

Answer:

see the picture

Step-by-step explanation:

By the below figure (6) is the initial equation

(1) next added (b/2a)^2 on both sides to make it whole square on left side which gives (4) in (4) both terms are added on the right side to make it (5)

then square root on both sides gives (2) and now taking b/2a to the right side gives the final quadratic formula (3)

We can obtain the quadratic formula from completing the square method as shown.

The quadratic formula is derived from the completing the square method as follows;

Given the quadratic equation;

[tex]ax^{2} + bx + c =0[/tex]

Dividing through by a we have;

[tex]x^{2} + \frac{b}{a} + \frac{c}{a} = 0[/tex]

Adding half of b to both sides of the equation, we have;

[tex](x + \frac{b}{a}) ^{2} = \frac{-c}{a} + \frac{b^2}{4a^2}[/tex]

Taking LCM of the right hand side;

[tex](x + \frac{b}{2a})^{2} = \frac{b^2 - 4ac}{4a^2}[/tex]

Making x the subject of the formula;

[tex]x = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

Step-by-step explanation:

Step-by-step explanation:

Slope = 3/4

Point = (4,-2)

Using the point Slope form ,

=> x - 4 = 3/4 ( y -(-2))

=> x -4 = 3/4 ( y -2)

=> 4x -16 = 3y -6

=> 4x -3y -16+6=0

=> 4x -3y -10 = 0

En esta pregunta debemos derivar ecuaciones algebraicas a partir de la información dada en el enunciado:

Diferencia entre cajas grandes y cajas pequeñas

[tex]m - n = 1[/tex] (1)

Donde:

Diferencia entre la cantidad de bombones en una caja grande y la cantidad de bombones en una caja pequeña

[tex]x-y = 5[/tex] (2)

Donde:

Total de bombones en cajas grandes

[tex]x\cdot m = 60[/tex] (3)

Total de bombones en cajas pequeñas

[tex]y\cdot n = 60[/tex] (4)

By (3) and (4) in (2):

[tex]\frac{60}{m} - \frac{60}{n} = 5[/tex]

[tex]60\cdot n - 60\cdot m = 5\cdot m\cdot n[/tex] (5)

By (1):

[tex]m = 1 + n[/tex]

(1) in (5):

[tex]60\cdot n - 60\cdot (1+n) = 5\cdot (1+n)\cdot n[/tex]

[tex]60 = 5\cdot n +5\cdot n^{2}[/tex]

[tex]5\cdot n^{2}+5\cdot n -60 = 0[/tex]

[tex]n^{2}+n-12 = 0[/tex]

Step-by-step explanation:

Number 1

m = (y2 - y1)/(x2 - x1)

m = (3 - 1)/(5 - 2)

m = 2/3 POSITIVE

Number 2

m = (y2 - y1)/(x2 - x1)

m = (-3 - 1)/(1 + 2)

m = -4/3 NEGATIVE

Number 3

m = (y2 - y1)/(x2 - x1)

m = (1 - 1)/(5 - 4)

m = 0/1

m = 0 ZERO

Number 4

m = (y2 - y1)/(x2 - x1)

m = (5 - 1)/(7 - 7)

m = 4/0

m = UNDEFINED

Answer:

⇛-13/8 , -11/24, -7/16, -5/12 , -3/8

Step-by-step explanation:

Given numbers are -3/8 , 5/-12, -7/16, -13/18 , 11/-24

The can be written as -3/8, -5/12, -7/16, -13/18, -11/24

The denominators = 8,12,16,18,24

LCM of the denominators = 144

-3/8 = (-3/8)×(18/18) = -54/144

-5/12 = (-5/12)×(12/12) =-60/144

-7/16 = (-7/16)×(9/9) = -63/144

-13/18 = (-13/18)×(8/8) = -104/144

-11/24 = (-11/24)×(6/6) = -66/144

Ascending order of the numbers

= -104/144 , -66/144, -63/144, -60/144, -54/144

Answer:

Step-by-step explanation:

x^2 + y^2 = 9, or x^2 + y^2 = 3^2, is the equation of a circle with center at (0, 0) and radius 2.  It does not represent a line such as y = mx + b.

If you were given both x^2 + y^2 = 9 and y = mx + b, you could find zero, or one, or two points of intersection between circle and line.

x^2 + y^2 = 9 could be solved for either x or y as follows:

x^2 = 9 - y^2, so that x = ±√(9 - y^2).  This is valid for 0 ≤ y < infinity, but again we have not "solve in  y = mx + b" format.
