Answer:
60m
Step-by-step explanation:
height =2+2×(let x be the length of the base)
area=1/2bh
30=1/2(2+2×)
30=2/2+2×/2
30=1+2×/2
30=1+×
30-1=×
29=
height=2+2×
2+2(29)
2+58
60
therefore the height is 60m
Answer:
Glados makes $44.76 per hour.

Archy: 15 gallons ... $23.85
1 gallon ...$ x = ?
x * 15 = 1 * 23.85 /15
x = 23.85 / 15
x = $1.59 per gallon
Joe: 16 gallons ... $24.48
1 gallon ... $ y = ?
y * 16 = 1 * 24.48 /16
y = 24.48 / 16
y = $1.53 per gallon
Result: Joe paid less per gallon.
