Jorge started the month with a balance of $400 in his checking account and ended the month with $450 what is the percent of the increase or decrease

%12.5

Step-by-step explanation:

Step 1:  Make an equation

400x = 450

Step 2:  Divide both sides by 400

400x / 400 = 450 / 400

x = 1.125

Step 3:  Convert into a percentage

1.125 * 100

%112.5

The increase is %12.5

 %12.5

This questions shows a percent increase.

Formula: (new value - old value) ÷ old value * 100%

= (450 - 400) ÷ 400 * 100%

= 50 ÷ 400 * 100%

= 0.125 * 100%

= 12.5% increase.

Best of Luck!

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
