What percent is the change in the price if the price was $100 and now it is $1250?
Vsevolod [243]

Answer:

  1150%

Step-by-step explanation:

The percentage change is ...

  percentage change = (amount of change)/(original amount) × 100%

  = ((new amount) - (original amount))/(original amount) × 100%

  = ($1250 -$100)/$100 × 100%

  = 1150/100 × 100%

  = 1150%

Solve the system of equations -x-2y=0 and -x+y=6 by combining the equations
Elden [556K]

Answer:

x=-4 and y=10

Step-by-step explanation:

Use the second equation to make y=x+6

sub y=x+6 into the first equation

-x-2*(x+6)=0

-x-2x-12=0

-3x-12=0

3x=-12

x=-4

Now sub x=-4 into the second equation

-(-4)+y=6

y=6+4

y=10

Find values of sine cosine tangent for
slava [35]

Answer:

The correct answer is option a

Sin A = 2√13/13

Cos A  = 3√13/13

Tan A = 2/3

Step-by-step explanation:

From the figure we can see that,a right angled triangle.

ΔABC

<u>To find side AB </u>

AB = √(AC)² + (BC)² =√(36² - 24² )= √1872

AC = 12√13

<u> To find the trigonometric ratio </u>

Sin A = BC/AB = 24/12√13  = 2√13/13

Cos A = AC/AB = 36/ 12√13  = 3√13/13

Tan A = BC/AC = 24/36 = 2/3
