Francesca has 63 cm of ribbon. she will cut it into two pieces so that the longer piece is 15 cm longer than the shorter piece. what will the length of the longer piece be?

The length of the longer piece will be

Step-by-step explanation:

Let

x------> the longer piece

y-----> the shorter piece

we know that

------> equation A

------> equation B

substitute the equation B in equation A

solve for y

Find the value of x

-------->

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
