when rounding a number to the nearest thousand we have to first check the digit in the hundreds place.
if the digit in the hundreds place is equal to or greater than 5 then we increase the value of the thousands place by 1
If the digit in the hundreds place is lesser than 5 then there's no change to the digit in the thousands place
number given is 18 366
digit in the thousands place is 8
digit in the hundreds place is 3. This is lesser than 5 therefore no change is done to the digit in the thousands place. So no change is done to 8.
therefore 18 366 rounded off to the nearest thousand is
18,000
Answer:
length of an arc = 1unit
Step-by-step explanation:
given that the circumference of a circle = 6
central angle = 60
length of the arc =?
recall that the circumference of a circle = 2πr
6 = 2πr
r = 6/2π
now to calculate the length of an arc
recall,
length of an arc = 2πr(Ф/360)
length of an arc = 2π(6/2π) × 60/360
length of an arc = 6 × 60/360
length of an arc = 360/360
length of an arc = 1unit
therefore the length of the arc whose circumference is 6 and arc angle is 60° is evaluated to be 1unit
We use scientific notation to make it easier to represent numbers very small to very large. EX: 6,000 Scientific Notation: 6^3
First, combine like terms to get 4n-7=5n+1
add 7 to both sides to get 4n=5n+8
subtract 5n from both sides to get -n=8
multiply both sides by -1 to get an answer of n=-8
First simplify inside parenthasees
8-6x+12
-6x+8+12
-6x+20
distributive poproty
a(b+c)=ab+ac
1/4(-6x+20)=-6x/4+20/4=
-3/2x+5
