Answer:
n = 8
Step-by-step explanation:
10=6+n/2
Switch sides
6 + n/2 = 10
Subtract 6 from both sides
6 + n/2 -6 = 10-6
Simplify
n/2 = 4
Multiply both sides by 2
2n/2 = 4 times 2
n = 8
Hope this helps!
Answer:
h=10m
Step-by-step explanation:
let the angle at bottom left corner be x
tan x= 18.2/12
x=56.602(5sf) (i used degree
h=12sin56.602
=10.018m(5sf)
Answer:
Larry.
Step-by-step explanation:
For Larry, do 375/25 = 15. He is getting paid $15 an hour.
For Kyle, you do 560/40 = 14. He is getting paid $14 an hour.
$15 is greater than $14 an hour, so Larry is getting paid at a better rate.
