Well, 9 billion = 9,000,000,000 so in scientific form it would be 9 x 10^9 To get the exponent, just count the number of zeros, which for 9 billion we have 9

$9 billion has 9 zeros so would be written as 9,000,000,000

 to write in scientific notation move the decimal point 9 places to the left so the number becomes 9

now that would be multiplied by 10 to an exponent. The exponent is equal to the number of spaced you moved the decimal point. In this case you moved it 9 places

 so scientific notation is 9x10^9


 1960 debt was 2.86x10^9, 2010 debt was 1.3562*10^13 -= 2.1x10^4 times more

In science, rate is a<span> quantity measured with respect to another measured quantity. For the data given, we get the rate of each by calculating the slope. We do as follows:

Megan's rate = 12 - 4.5 / 4 -1 = 2.5 inches per week
Suzanne's rate = 11 - 5 / 4-1 = 0.5 inches per week

What values of b satisfy 4(3b + 2)2 = 64?
rodikova [14]
Assuming yo meant
4(3b+2)²=64

divide both sides by 4
(3b+2)²=16
sqrt both sides
remember to take positive and negative roots
3b+2=+/-4
minus 2 both sides
3b=-2+/-4
divide by 3
b=(-2+/-4)/3
b=(-2+4)/3 or (-2-4)/3
b=2/3 or -6/3
b=2/3 or -2

Two rectangular properties share a common side. Lot A is 33 feet wide and 42 feet long.
s344n2d4d5 [400]

Answer:

The width of lot B is 11 feet, so option A is correct.

Step-by-step explanation:

Given:

  • Two rectangular properties share a common side.  
  • Lot A is 33 feet wide and 42 feet long.  
  • The combined area of the lots = 1,848 square feet.  

To find:

How many feet wide is Lot B?  

Solution:

we know that, area of a rectangle is length x breadth

Then area of lot A = 33 x 42 = 1386 square feet.

And area of lot B = width x 42

Now, we are given that, total area = 1848  

area of lot A + area of lot B = 1848  

1386 + width x 42 = 1848  

width x 42 = 1848 – 1386  

width x 42 = 462  

width =\frac{42}{462}

width = 11

Hence, the width of lot B is 11 feet, so option A is correct.
