How Do You Determine Where To Place The Decimal Point In The Product( Please Quick I Have 10 Other Q

Answers

Answer 1

Answer:

Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product. To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is 4 mph. What is the speed of the flying carpet in still air?

Answers

Answer:

[tex]15.2~mph[/tex]

Step-by-step explanation:

Let the time flown by the flying carpet be [tex]t[/tex]. Then, we have that [tex](2.4)/t=(1.4)/t+2*4[/tex].

We multiply both sides of the equation by [tex]t[/tex] to get [tex]2.4=1.4+8t[/tex].

We subtract [tex]1.4[/tex] from both sides to get [tex]1=8t[/tex].

We divide both sides of the equation by [tex]t=1/8[/tex].

We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.

The speed with wind is [tex](2.4)/(1/8)=19.2[/tex]mph.

The speed against wind is [tex](1.4)/(1/8)=11.2[/tex]mph.

The speed in still wind is [tex](19.2+11.2)/2=(30.4)/2=15.2[/tex].

Therefore, the answer is [tex]\boxed{15.2~mph}[/tex] and we're done!

The speed of the flying carpet in still air is 15.2 mph

Let x represent the speed of the flying carpet in still air, and t represent the time.

Speed = distance/time

Since the wind speed is 4 mph, hence:

When flying with the wind:

x + 4 mph = 2.4/t     (1)

When flying against the wind:

x - 4 mph = 1.4/t     (2)

Dividing equation 1 by 2 gives:

(x + 4) / (x - 4) = 2.4/1.4

1.4x + 5.6 = 2.4x - 9.6

x = 15.2 mph

The speed of the flying carpet in still air is 15.2 mph

Three teams, A, B and C, play in a competition.
games won by A: games won by B = 4:3
games won by B: games won by C = 5:2
Team B has won 30 games.
In total, how many games have the three teams won?

Answers

ANSWER:

     43

Explanation:

A : B : C

     4 : 3  

          5 : 2

A × B → 4 × 5 = 20

B × B → 3 × 5 = 15

B × C → 3 × 2 = 6

  A : B : C

 20 : 15 : 6

B = 15 = 30

what of teams A and C together?

 If 15 = 30games, what about 26games?

Cross multiply.

   15 × 26          =13

      30

So, games won by Team B + games won by Teams A and C

        30games + 13games

               =43games.

Simplify the expression -5+i/2i
Step by step

Answers

Answer:

For complex numbers,

a + bi and a - bi

they have the interesting property that if you add them you get the real number 2a

and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2

But since i^2 = -1, we end up with a real number as a product.

e.g. 6 - 5i and 6 + 5i are conjugates of each other

sum = 6-5i + 6+5i = 12

product = 36 - 25i^2

= 36 -(-25) = 61

Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i

Also I believe, according to the answer, that you have a typo, and you meant

(-5+i)/(2i)

= (-5+i)/(2i) *i/i

= (-5i + i^2)/2i^2)

= (-5i +i^2)/-2

= (-5i - 1)/-2

= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2

Step-by-step explanation:

Since we already know what x we can just substitute it.

5(8)-2y=30

5 times 8 is 40

40-2y=30

Subtract 40 on both sides:

-2y=-10

Divide -2 on both sides:

y=5

find (x+55)°
find (3x-5)°
find x

Answers

Answer:

x = 30

Step-by-step explanation:

The two angles are congruent so they have the same value

3x-5 = x+55

Subtract x from each side

3x-5 -x = x+55-x

2x-5 = 55

Add 5 to each side

2x-5+5 = 55+5

2x= 60

Divide each side by 2

2x/2 = 60/2

x = 30

You would get

x=40
