Shaun and kendra want to scan old family photos into a computer photo organizing
program. on his laptop shaun can scan about five photos in three minutes. kendra can
scan about eight photos in five minutes on her computer. working together, how many
minutes (t) would it take for both of them to scan 36 photos?
.

Approximately 11 minutes

Step-by-step explanation:

Let t be the time in minutes working together.

Shaun: 5/3 photos per minute

Kendra: 8/5 photos per minute

Combined: 36/t photos per minute

5/3 + 8/5 = 36/t

15t(5/3 + 8/5) = 15t(36/t)

25t + 24t = 540

49t = 540

t = 540/49 = 11.02

Approximately 11 minutes

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.
