Step-by-step explanation:

So for this we have to find the percentage by using 'percentage of error'

If at first it was 15 then it went up to 19 we have to subtract 15 - 19= -4

Ignore the negative. Now divide= 4/19= 0.21

The size went up by 21%

X+2y=10 6y=--3x+30 Use algebraic rules of equations to predict the solution to the system of equations.

MaRussiya [10]

X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)

From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)

Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.

Find the length of each arc<br> r=13 ft x=90 degrees

VladimirAG [237]

Answer:

$13\pi/2$

Step-by-step explanation:

The formula of the circumference of a circle is $2\pi r$ .

The length of an arch can be found by using the ratio of circumference to the arc.

First, find the circumference of the circle:

$2\pi *13=26\pi$

Then you find the ratio:

The length of the arc is 90/360, which is 1/4, of the circumference.

Finally, find the length of the arc:

$26\pi*1/4=(13/2)\pi$ or $13\pi/2$

I hope this helps :)
