Answer: The population after five years = 9967

Step-by-step explanation:

The exponential equation for population decay : [tex]P=A (1-r)^t[/tex], where A = initial population r= rate of decay , t= time

Given: A= 42000, r= 25%= 0.25, t= 5

then

[tex]P=42000(1-0.25)^5\\\\=42000(0.75)^5\\\\=42000(0.2373046875)\\\\\approx9967[/tex]

Hence, The population after five years = 9967

Answer:

3/1 ; 0/3 ; -191/32 ; 3/456

Step-by-step explanation:

We have to find all the numbers that are expressed with a fraction:

1) is a trap because the division is impossibile

2) true: 3/1 is a fraction

3) true: 0/3 is a possible division and it results 0

4) true: is a fraction

5) true: is a fraction

Answer:

so the discount is 42 and the bill is $78

Step-by-step explanation:

0.35*120=42

discount is 42

120-42=78

the bill is $78

Answer:

-2 (filled in circle) to 7 (open circle)

Step-by-step explanation:

for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.

solving it:

-3(x) [tex]\leq[/tex] 6

[tex]\frac{-3x}{-3} \leq \frac{6}{-3}[/tex]

[tex]x\leq -2[/tex]

for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle

solving it:

[tex]2x + 3 (- 3) < 17 (- 3)[/tex]

2x < 14

[tex]\frac{2x}{2} <\frac{14}{2}[/tex]

x < 7

my explanation is all over the place, but hope this helps!!!

Answer

364 i think

Step-by-step explanation:

find the area of triangles + area of rectangles

area of triangles: b x h x 1/2

6 x 4 x 1/2

= 12

but two triangles, so . double it and then you get 24 for the two triangles areA

area of rectangles;

l x w

22 x 6

= 132

but two up and down rectangles, so double it = 264

now back rectangle:

l x w

22 x 4

= 88

Add it all up together and you have the surface area!

Surface Area - The area of the surface of the 3D object, NOT volume

pls mark brainliest unless someone else answered it or im wrong thank you! :D

Given

The statement is "three times three".

To find:

The value of given statement.

Solution:

We know that the multiplication sign "×" is used for "times".

The given statement is "three times three".

So, the mathematical expression for the given statement is:

three times three = 3 × 3

                             = 9

Therefore, the value of three times three is 9.

Answer:

x = -3

Step-by-step explanation:

4x - 5 + 2(x - 3) = 12x + 7

4x - 5 + 2x - 6 = 12x + 7

6x - 11 = 12x +7

6x - 12x = 7 + 11

-6x = 18

x = -3

Answer:

La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]

Step-by-step explanation:

La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.

[tex]P(A)=\frac{numero de casos favorables}{numero de casos posibles}[/tex]

En este caso:

Reemplazando:

P(A)= [tex]\frac{2}{7}[/tex]

La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]

Answer:

x = 1/3 x=0

Step-by-step explanation:

y=6x-2

2=6x

2/6 = x

1/3=x

y=5x

5x=0

divide both sides by 5

0/5 = 0
