What is (3x10) + (6x1) + (9x1/10) + (4x1/100) in standard form

Answers

Answer 1
Answer: 30+6+0.9+0.04= 36.94
Answer 2
Answer: Standard Form just means in numbers e.g. 501.60

Writing this in huge spacing makes it easier for us:
3 * 10  +     6 * 1    +     (9 * 1)/10    +     (4 * 1) /100
   30    +         6      +        0.9          +       0.04  
= 36.94

Homer Simpson weighs 400 pounds. He is on a diet to lose 5 pounds each week Barney weighs 322 pounds. he is on a diet to lose 3 pounds each week. How long will it take for them to weigh the same? write an equation and solve.

Answers

400 + (n-1) (-5) = 322 + (n-1) (-3)
-5n + 5 = 322 
-3n + 3    | 405 - 5n
               =325 - 3n
80=2n
n=40            n - 1 = 39    

 Answer = 39 , 39 weeks until they weigh the same

The minute hand of a clock is 7 inches long how far does the point of the hand travel in one hour

Answers

The hand represents the radius of the circle of the clock, so we would want to find the perimeter of the circle to begin with to determine how far the point of the hand would travel full circle (12 hours) To do this we would use the equation 2(pi*radius) we would use 3.14 as pi in this equation.

p=2(3.14*7) solves to 43.98 inches. This means the point of the hand travels 48.98 inches in 12 hours, to find how far it moves in just one hour, we would divide 43.98 by 12. This gives us the final answer of 3.665 inches traveled in one hour.

Expand the expression and combine like terms:
−4(−11+4n)−3(−2n+9)

Answers

Easy,

-4(-11+4n)-3(-2n+9)

Take them apart and multiply them out...

-4(-11+4n)= 44-16n
and
-3(-2n+9)= 6n-27

Now add the apples and oranges..

44-16n+6n-27

44-27=17

-16n+6n=-10n

Thus, your answer is, -10n+17.
−4(−11+4n)−3(−2n+9)

44 - 16n + 6n - 27

17 - 10n = 0

17 = 10n

n = 
(17)/(10)

David has a piece of wood measuring 12 1/8 feet that he wants to use for a project. He needs to cut the wood into pieces that measure 1 13/16 feet.How many pieces of wood can he cut measuring exactly 1 13/16 feet?

Answers

So, it would be the wisest to work in decimals for this problem.

So we have to divide 12.125 by 1.8125 to see how many times the latter goes into the former.(12.125)/(1.8125)\approx 6.68965517

So, since the problem asks for how many lengths can go in without remainder, our answer would simply be 6.
