4 0

Answer:

arc = 7 pi

Step-by-step explanation:

The length of the arc is circumference

C = 2 * pi *r

C = 2 * pi *4

C = 8 pi

A circle is 360 degrees.  The arc is 315 degrees

The arc is 315/360 of the circle, that is 7/8 of the circle, so it will be 7/8 of the circumference

7/8C = 7/8 (8pi)

arc = 7 pi

padilas [110]

Katie has $2726.88 to spend each month after taxes and savings

Step-by-step explanation:

The information about Katie's monthly salary is:

1. The gross monthly salary is $3800

2. The income taxes is 22% of her income

3. She saves 8% of her salary

We need to find how much Katie has to spend each month​ after taxes

and savings

∵ The income taxes is 22% of her income

∵ Her income is $3800

∴ The income taxes = \frac{22}{100} × 3800

∴ The income taxes = $836

∴ The remaining of her salary after taxes = 3800 - 836

∴ The remaining of her salary after taxes = $2964

∵ She saves 8% of here salary

∵ Her salary after taxes = $2964

∴ Her savings = \frac{8}{100} × 2964

∴ Her savings = $237.12

∴ The remaining of her salary after saving = 2964 - 237.12

∴ The remaining of her salary after saving = $2726.88

Katie has $2726.88 to spend each month after taxes and savings
