two decimal numbers have digits to the thousands place if you multiply them how many digits do you expect there to be after the

There will be 6 decimal digits in the product of the numbers and can be fewer than 6.

<h3>What are decimal numbers?</h3>

A decimal number has a whole number and a fractional part.

Given that the two decimal numbers have digits to the thousandth place.

Therefore, there are three digits after the decimal point.

The number of digits after the decimal point in the product of two decimal numbers is the sum of the digits after the decimal point in both numbers.

Let the first number be 0.001 and the second number be 0.002.

Then, the number of decimal digits in the product of 0.001 and 0.002 will be 6.

If the two numbers are 0.005 and 0.002, then surely, there will be less than 6 digits after the decimal as the last 0 can be omitted in counting.

Hence, there will be 6 decimal digits in the product of the numbers and can be fewer than 6.

In how many ways can you seat 5 women and 5 men in a row if women must seat next to each other,men must seat next to each other,
makvit [3.9K]

Answer: 288ways

Step-by-step explanation:

There are 5men and 5women to be arranged, since the men must seat together, they will be arranged in 5! ways. For the women, since they must also seat together but with siamese twins between them, they can be arranged in 4! ways instead of 5! ways and this is due to presence of the twins among them.

Note that Siamese twins cannot be separated as such both are taken as one making it 4!.

Since the women and men are always sitting together, they can be arranged in 2! ways i.e 2 sexes

The final seating arrangement can be done in 2!×(5!+4!) ways

= 2× (120+24)

= 2×144

= 288ways.

Note that the arrangement of the men and women are added because they can only be arranged differently to ensure different sex are not sitting together.

Ken wants to buy some coffee mugs, m , that cost $5 each and some ground coffee, C, that costs $8 a pound. He has $25.
ValentinkaMS [17]

The inequality representation of the scenario is :

  • 5m + 8c ≤ 25
  • m = 1 and c = 1

  • Number of mugs = m
  • Cost per mug = $5
  • Number of ground coffee = c
  • Cost per ground coffee = $8
  • Total amount to spend = $25

  • (Number of mug × cost per mug) + (Number of ground coffee × cost of ground coffee) ≤total amount to spend

  • Representing as an inequality : 5m + 8c ≤ 25

Combination of m and c that makes the inequality true :

  • Using trial by error :
  • m = 1 and c = 1
  • 5(1) + 8(1) ≤ 25 ; 13 ≤ 25

Hence, m = 1 and c =1 are valid values for the expression.

How do I write this in slope intercept form: (-3,-4) and (4,-3)
DENIUS [597]
Slope intercept form is y = mx + b

Pick one of the coordinates, I’ll use (-3,-4) as the example.

Coordinates are just numbers plugged in for (x,y).

This means -3 would be your x and -4 would be your y.

So plug these numbers into the equation and you get -4 = m(-3) + b.

M is slope and to find slope, you need to do (y2-y1) / (x2-x1).

In other words, it would be (-3 - -4) / (4 - -3) = 1/7 which is your slope (m).

Now plug that in for m to get the b variable.

-4 = 1/7(-3) + b.

B = -3.57

Your answer is y = 1/7x -3.57

What is the solution to x – 10 &gt; – 12?<br><br> (–∞, –18)<br> (–18, ∞)<br> (–∞, 18)<br> (18, ∞)
Allisa [31]

Answer:

(18, ∞)

Step-by-step explanation:

(18, ∞) is the only option that works. if we ignore the "greater than" sign, and just set the function equal to -12, we see that x-10=-12 would give us x=-2. If we plug in -3 for x, we get -13, which is less than -12. if we plug in -1 for x, we get -11, which is greater than -12. Therefore, with the function only having one critical point (zero), we know that every value greater than -2 is a solution. Technically, the full solution would be (-2, ∞). however, the only answer available meeting the criteria would be (18, ∞).

A string is cut into two pieces in the ratio 2 : 7. The difference between the lengths of the two pieces is 90cm. Find the lengt
Nataly_w [17]

Answer:the length of the shorter string= 36cm

Step-by-step explanation:

Let us assume the lengths are 2x and 7x  since thery are in the ratio of 2 :7

 Such that Length of the shorter string = 2x

and the longer string = 7x  so that  the difference in Length which is 90cm can be expressed as

7x- 2x= 90

5x= 90

x 90/5

x= 18

shorter string = 2 x = 2x 18= 36cm

Longer strring = 7x 18=126cm
