Answer:
It is D
Step-by-step explanation:
Because,
The sign ">" should have an underline and the point starts at 4, not 3. If it is not correct, I am sorry.
I be live it would be 35 because you would just multiply 7x5 which I'd how I got my answer 35
We know that
[length of a circumference ]=2*pi*r
for r=1 units
[length of a circumference ]=2*pi*1------> 2*pi units
if 2*pi radians (full circle) has a length of-----------------> 2*pi units
pi/3 radians-----------------------------> X
X=(pi/3)*2*pi/(2*pi)-----> pi/3 units
the answer is
pi/3
Answer:
Chang has to work 9 hours to make $112
Step-by-step explanation:
Amount made in an hour = Total amount/total hours worked
= $16
Duration he has work to make $112 = 112/16
= 9 hours
I am assuming that 114114 is actually 114.
Toni: 20 + 0.80/lap
Marcy: 15 + 0.85/lap
Marcy: x laps
Toni: 114x laps
[20 + 0.80(114x)] + [15 + 0.85x] = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x = 257 - 35
92.05x = 222
x = 222/92.05
x = 2.41 laps
Marcy: x = 2.41 laps
Toni: 114x = 114(2.41) = 274.74 laps
20 + 0.80(274.74) = 20 + 219.79 = 239.79 or 240
15 + 0.85(2.41) = 15 + 2.05 = 17.05 or 17
240 + 17 = 257
