The caret (^) is the symbol conventionally used to indicate an exponent.
You have
area = 2.76·10^12
width = 4.6·10^5
You want to find the perimeter of the rectangle with these dimensions.
The perimeter of a rectangle is twice the sum of length and width.
perimeter = 2*(length + width)
The length can be figured from the area using the formula for area.
area = length*width
area/width = length . . . . . . . . . divide by width
Filling in the numbers, we have
perimeter = 2*((2.76·10^12)/(4.6·10^5) +(4.6·10^5))
perimeter = 2*(6.0·10^6 +0.46·10^6)
perimeter = 2*6.46·10^6 = 1.292·10^7
The perimeter of the rectangle is ...
1.292·10^7
Chose a fraction with a denometer of 8.
Ex: 3/8
To compare 5/6 and 3/8 we need to find the LCM (the lowest common denominator.)
This can easily be done by listing the multiples of each number.
6: 6, 12, 18, 24, 30, 36
8: 8, 16, 24, 32, 40, 48
The Lowest common denominator would be 24.
6*4=40
8*3=40
Since we altered the denometer, either by multyplying by 6 or 8 (to get 24), we must do the same for the numerator.
3/8*3
9/24
5/6*4
20/24
Now we compare the fraction properly.
20 is larger than 9 so we know that 3/8 is less than 5/6.
Hope this helps! Please leave a thanks/braniest answer!
Answer:
y=3
Step-by-step explanation:
To solve this 2 step equation, we need to get y alone. Lets write out the equation
-2y+16=10
Subtract 16 from both sides
-2y-16+16=10-16
Subtract
-2y=-6
divide both sides by -2
-2y/-2=-6/-2
divide
y=3
Answer:
x = 11
Step-by-step explanation:
6x - 21 = 3x + 12
6x - 3x = 21 + 12
3x = 33
x = 33/3
x = 11
