We know that 1 mm=0.01 dm
75 mm=0.75 dm
choice D
Answer:
Simple, 4*pi*r^2
Step-by-step explanation:
Step-by-step explanation:
he has 900-230 = 670 more push-ups to do in the remaining 20 days.
so, he has to do every day
670/20 = 67/2 = 33.5 push-ups.
fractions of push-ups don't make sense.
we cannot say, he has to do at least 33 per day, because then he might come short in the end (if he sticks to the low limit) .
so, we have to say he has to do more than 33 or at least 34 push-ups per day to be sure he will at least reach his goal.
p > 33
or
p >= 34
both should be correct in the context of using only whole numbers.
bur in case of doubt I would pick p >= 34.
She can plant 34 plants in all. If you multiply 34 and 2 you will get 34 and I think that is the answer.
3 - (7a + 1) =
3 - 7a - 1 =
-7a + 2 <===
