For rounding, if the place one more to the right of the place you are rounding is 0-4, you go down. If it is 5-9, then round up. For the first one, you are rounding to hundreds, so look at the tens. It ends on a 5, so round up. Making the number 700. For the second one, look at the tens again, and you see it is more than 5, so it is 800. The last one is tricky, but do-able. Look at the hundreds. It’s a four. So that means you keep the same number, making it 6,000. I hope this helps!
Answer:
y=3
Step-by-step explanation:
not too sure if you have sin square .
if it's sin square.
so y= 3+5sin^2(0- pie)
so the answer will be y=3
because
if you multiple 5sin square to (0-pie) =0
so you y=3.
if the equation is not what I wrote post the equation with a pic , I will help if I see it.
hope that helps
Step-by-step explanation:
Speed = Distance / Time
given distance = 6km
time = 30 minutes = 30/60 hr = 1/2hr
speed =
So, (6a - X)*5a = Y*(a^2) - 35a
<span>=> 6a*5a - X*5a = Y*(a^2) - 35a </span>
<span>=> 30(a^2) - X*5a = Y(a^2) - 35a
</span>30 = Y and
<span>X*5 = 35 or X = 7 </span>
The coefficient of 'y' in her simplified answer is 10.
