The first amount would be the original amount as the answer because you are adding and then subtracting the same number. If the increase was 150% then the answer would be 50% more because 150%-100%=50%.

PLEASE HELP ME!! I GAVE ALL MY POINTS! EXPLAIN IF POSSIBLE
SpyIntel [72]

Answer:

  • 10 mice left after 5 years

Step-by-step explanation:

<u>The function is given:</u>

  • f(x) = 5719(0.28)ˣ
  • f(x) is the number of mice left after x years, 5719 is initial number of mice (now) and x is the number of years from now

<u>Substitute x with 5 for 5 years and find the value of the function.</u>

  • f(5) = 5719(0.28)⁵ = 10 (rounded up to the integer number)
  • Multiply 5719 by 0.28 to the 5th power to get approximate number of 10

There will be 10 mice left after 5 years

I have 3 types of shapes: triangle, square or circle in the ratio 3:6:1. The triangles are either red or blue. The ratio of red
erma4kov [3.2K]
Ok first lets take care of the color
given that you have 12 red triangles and the ratio for red triangles to blue triangles is 4:5
if 12=4 than blue=5
12 times 5= 60
12 times 4 = 48
48 red and 60 blue = triangles
48+60=108
there are 108 triangles in total
now since the ratio for triangle square or circle is 
for every 3 triangles there are 6 squares and for every six squares there is one circle
t3:s6:c1
since there are 108 triangles
108/3=36
since for every 3 triangles there are 6 squares 
six times 36(amount of triangles/3)
6*36+=216
so there are 216 squares
now it says for every six squares there is one circle
therefor (the amount of squares)216/6+= 36 
we are back to 36 and there are 36 circles

Sec^4x-tan^4x=sec^2x+tan^2x
tino4ka555 [31]
\sec^4x-\tan^4x=(\sec^2x-\tan^2)(\sec^2x+\tan^2x)=\sec^2x+\tan^2x

since \tan^2x+1=\sec^2x.

In AABC, what is the value of x?
Dennis_Churaev [7]

Answer:

x = 6.5

Step-by-step explanation:

* since it's a triangle ALL the angles inside should give you 180° * Equate everything to 180°

8x + 10x - 10°+ 10x + 8° = 180°( sum of angles on a triangle)

28x - 2° = 180° * group like terms*

28x = 182°

x = 6.5
