The simplified mathematical expressions with the first factor to the nearest tenth are:

7.8 x 10

3.3 x 10^{3}

2.1 x 10^{-3}

3.7

<h3>What are the simplified mathematical expressions ?</h3>

Scientific notation is used to simplify large numbers in smaller numbers.  In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

(8.6 x 10^{7}) . (9.1 x 10^{-8})

= (8.6 x 9.1) x 10^{7 - 8}

= 78.26 x10^{-1}

= 7.8 x 10

(6.9 x 10^{5}) . (4.8 x 10^{-3})

= 33.12 x 10^{5 - 3}

3.3 x 10^{3}

(3.7 x 10^{2}) . (4.6 x 10^{-3}) ÷ (1.4 x 10^{-6}) . (5.7 x 10^{8})

= 1.7 x 10 ÷ 8 x10²

0.21 x 10^{-2}

2.1 x 10^{-3}

(3.1 x 10^{5}) . (5.3 x 10^{-9}) ÷ (7.3 x 10^{2}) . (6.1 x 10^{-7}) = 3.7

Answer:

Step-by-step explanation:

What we know

total sum of angles = 540 deg

3/2 b cam also be written as 1.5b degrees.

So 1.5b + (b+45) + (2b - 90) +90 = 540

Step 1 -- get rid of parenthesis

         1.5b + b + 45 +2b -90 +90 =540

Step 2 -- combine the like expressions

         4.5b + 45 = 540

Step 3 -- subtract 45 from both the sides

         4.5b = 495

Step 4 -- divide 4.5 from both the sides

         b = 110  ----- not the right answer

Thats not right okay im sorry

but i guess if it is not 110 it should be 100, 90 etc.

90 = b is correct

The question is asking to make facts about the graph. Do you see any domain,range, maximum or minimum, etc. you didn’t add the graph. So remember that
Domain is all possible input (x) values
Range is all possible output (y) values
Function is the x-values can NOT repeat.

1) You will begin by writing down the definition of "monetary policy."
stepan [7]

It should be noted that monetary policy simply means the policy that's adopted by the monetary authority in a country in order to control interest rates and the money supply.

<h3>Monetary policy.</h3>

Your information is unclear but the clear and complete ones will be answered appropriately. The main monetary policies include the reserve requirement, open market operations, discount rate, and the interest on reserves.

It should be noted that a larger money supply leads to the reduction of the market interest rates. This makes it less expensive for consumers to borrow.

Also, a smaller money supply raises the market interest rates. Expansionary monetary policy leads to an increase in the money supply. This will lead to an increase in expenditure and therefore, the aggregate demand will shift to the right.
