In the given mathematical
value of 51, 487 to round off this number to the nearest thousand, we can
elaborate the number values using the expanded form to clearly see the order
position:
<span><span>1. </span><span> 50, 000 = ten
thousands</span></span>
<span><span>2. </span><span> 1, 000 =
thousands</span></span>
<span><span>3. </span><span> 400 = hundreds</span></span>
<span><span>4. </span><span> 80 = tens</span></span>
<span><span>5. </span><span> 7 = ones</span></span>
Now we can observe the
numerical value of 51, 487 than 1, 000 is the number in which belongs to the
thousands’ position hence since the nearest number is 400 the value will be 51,
000.
Around 4.5π. This can be determined by the volume of a sphere formula.
Answer:
7.5 Hours (This is questioned weird though so it could be different)
Step-by-step explanation:
Just add 9 to 6 and you'll have 15 divided by two equals 7.5.
Or since it takes 6 hours for both, multiply by 2 equals 12
Triangular prism formula is 1/2 * height * base * other base, so 4.8 * 7.2 * 10 * 1/2 is 172.8.
2a^2b^3(4a^2+3ab^2-ab)=?
<span>
is what I presume you actually meant. </span>
<span>
Pull out the common factors of (4a^2+3ab^2-ab) and you will get </span>
<span>
a(4a+3b^2 -b) </span>
Substitute this back into the original equation and you get
<span>
2a^2b^3[a(4a+3b^2-b)] = </span>
2a^3b^3(4a+3b^2-b) =
<span>2a^3b^3(4a-b+3b^2)
</span>
