$540
Step-by-step explanation:
$150 × 4 = $600
$600 ÷ 10 = $60
$600 - $60 = $540
The angles of a triangle are right angles
90 = 1/3x + 8
82 = 1/3x
246 = x
Answer is B
Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
It would be 2 root 2
bc it simplifies to root 2 and root 4
root 4 simplifies to 2
so its 2√2
