How to multiply 8 with 0.9? Show your method. Link = report.​

Answer:

3 and 9

Step-by-step explanation:

let Peter's age be x then James is x + 6

The average of their ages is twice Peter's age, that is

[tex]\frac{x+x+6}{2}[/tex] = 2x

[tex]\frac{2x+6}{2}[/tex] = 2x

x + 3 = 2x ( subtract x from both sides )

3 = x

Then Peter is 3 years old and James is x + 6 = 3 + 6 = 9 years old

Answer:  ? = 0.14

Step-by-step explanation:

So you need to find the value that fits the question mark. This means you have to get it by itself.

To start you subtract 0.4 from 0.546, which equals .146. Then you subtract 0.006 from 0.146 to get 0.14

What it looks like mathematically :

0.546 = 0.4 + ? + 0.006  

0.146= ? + 0.006  

0.14=?

Hopes this helps :)

9 because all you have to do is put number by number in the calculator

Answer:

Answer:

  115/198

Step-by-step explanation:

The repeat is 2 digits, so you can multiply the number by 10 to that power.

  x = 0.58080...(2-digit repeat)

  100x = 58.08080...(2-digit repeat)

Then subtract the original number.

  100x -x = 99x = 58.08080... -0.58080... = 57.5

Now, divide by the coefficient of x.

  x = 57.5/99 = 115/198

This fraction cannot be reduced, so is the fraction you're looking for.

  0.580...(2-digit repeat) = 115/198

_____

Additional comment

The number of 9s in the denominator is the number of repeating digits. If the repeat started at the decimal point, the fraction would be those two repeating digits divided by two 9s (99).

Your number can be considered to be ...

  0.58080...(2-digit repeat) = 0.5 + 0.0808...(2-digit repeat)

This will be ...

  0.58080... = 1/2 + 8/99 = 99/198 +16/198 = 115/198

Step-by-step explanation:

[tex] \frac{16}{24} = \frac{2}{3} [/tex]

if we divide 16 ÷ 8 = 2

if we divide 24 ÷ 8 = 3

[tex] \frac{28}{42} = \frac{4}{6} = \frac{2}{ 3} [/tex]

if we divide 28 ÷ 7 = 4

if we divide 42 ÷7 = 6

we divide both 6 and 4 ÷2

2/3

[tex] \frac{16}{24} = \frac{28}{42} [/tex]

Answer:

$1,856.25

Explanation:

To find the square yards, multiply length and width

7.5 * 5 = 37.5

Then, since each square yard costs $49.50, multiply the square yards and the cost

37.5 * 49.50 = 1,856.25

Thus the answer is $1,856.25

The carpet for the room will cost $1,856.25.

This is the product of the unit cost per square yard multiplied by the area of the room.

The area of the room is = 37.5 square yards (Length x Width)

Length of the room = 7.5 yards

Width of the room = 5 yards

Therefore, the total area of the room = 37.5 square yards (7.5 x 5)

Thus, the total area of the room is 37.5 square yards and since each square yard costs $49.50, the total cost for buying the carpet will cost $1,856.25 ($49.50 x 37.5).

Step-by-step explanation:

List the multiples of both 12 and 9:

12, 24, 36, 48, 60

9, 18, 27, 36, 45

The lowest common multiple is 36.

This will make the fixtures and bulbs equal.

This means they bought 3 packages of light figures 3 x 12 = 36)

And bought 4 packages of bulbs ( 4 x 9 = 36)

Find out LCM of 9,12

Now

No of light packages=36/12=3

No of light bulbs=36/4=9

Answer:

Okay so, one pen equals to 25p, one rubber equals to 10p, and Erica bought a pencil, a rubber, and a ruler for 1 pound, which means 25p+10p equals to 35p, and 100-35= 65p, so one ruler costs 65p, so Horace bought a pencil, a ruler and a pen, we know one pencil equals 25p, a ruler costs 65p, and a pen also equals 25p, so 25+65+25 = 115, so 1pound 15 p

Answer:

Step-by-step explanation:

(a, b) We are given two pairs of values:

 (w, c) = (1900, 156) and (2600, 184)

so we can write the equation of the relationship using the 2-point form of the equation of a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  c = (184 -156)/(2600 -1900)(w -1900) +156 . . . . . substitute given points

  c = 28/700(w -1900) +156

  c(w) = 0.04w +80

The charge per cubic foot is $0.04.

__

(c) For a bill of $216, the amount of water used is ...

  216 = 0.04w +80

  136 = 0.04w

  3400 = w

Use of 3400 cubic feet of water would lead to a bill of $216.

Answer:

The average annual cumulative rainfall is  [tex]1[/tex] inch per month.

During month of August average rain fall is greatest because slope in this month is maximum.

Step-by-step explanation:

The graph does not represent cumulative rainfall as a function of day.

Because they have average all values for month Total cumulative rainfall is [tex]12[/tex] inches.

Total period is [tex]12[/tex] month

So average annual cumulative rainfall is

[tex]$12 / 12=1$[/tex] inch per month

Average rain fall in month of December= (average cumulative rainfall in December[tex])-([/tex]average  cumulative rainfall in November)

[tex]=12-11[/tex]

[tex]$=1$[/tex] inch

Answer:

Area = WxL=60 square inches

W = 5 inches

L = 12 inches

Step-by-step explanation:

Note, some teachers take points off if you don't include units!!

L = 2W+2

W = W

34 = 2L + 2W (perimeter)

34 = 2(2W+2) +2W solve for width

34 = 4W+4+2W = 6W+4

30 = 6W, so W=5

L = 2(5) +2 = 12
