4.2 times 105 is 441 and 5.3 times 105 is 556.5.
441 plus 556.5 is 997.5
So the answer is 997.5

Hey there!

So, first we would do a first part if this problem.

4.2*105 

This would equal . . . .

\boxed{\boxed{441}}
_____________________________________________________________

Then we would do the second part of the problem.

5.3*105

This would equal . . . .

\boxed{\boxed{556.5}}

(By adding both (441) and also (556.5)

This would equal . . . 
                                                   
 \boxed{\boxed{\boxed{997.5}}}

Hope this helps.

Answer:

Step-by-step explanation:

All the interior angles are of measure 60 degrees.

We want to find the height of this triangle.  Call it h.  On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.

The ratio of height to base is the tangent of 60 degrees:

                                    h

tan 60 degrees = --------------

                                     5

                                                  h

and tan 60 degrees = 1.73  = ------

                                                   5

Multiplying both sides of this equation by 5 yields h = 8.66.  This is |BD|.  This is the same as Answer B.

Henry is saving money to buy a game. so far he has saved $12 , which is three-fourths of the total cost of the game. how much do
vazorg [7]
Henry has 3 / 4 0f total cost so,
Let ( a ) is total cost of game

So,
3/4 × a = total cost


12 = 3/ 4 × a

4 will multiply with 12 so,

12 x 4 = 3 a

48 = 3a

48 / 3= a

16 = a will be price of game
