Answer:

3.5 of the liquid will contain 0.875g of the substance.

Step-by-step explanation:

The problem states that a liquid contains 0.25 mg of a substance per milliliter. And asks how many grams of the substance will 3.5 L contain.

First step: Conversion of 3.5L to ml

Each liter has 1000ml. So:

1L - 1,000mL

3.5L - xmL

x = 1,000*3.5

x = 3,500mL

Second step: How many miligrams are there in 3,500mL?

The problem states that each ml of the liquid contains 0.25mg of a substance. So

1ml - 0.25mg

3,500 mL - xmg

x = 3,500*0.25

x = 875mg

Final step: Conversion of 875mg to g.

Each g has 1000 mg. So

1g - 1000mg

xg - 875mg

1000x = 875

x = \frac{875}{1000}

x = 0.875g

3.5 of the liquid will contain 0.875g of the substance.

What is not a problem modular division is used for?
Oksana_A [137]

Answer:

First let's define what modular arithmetic is, what would come is an arithmetic system for equivalence classes of whole numbers called congruence classes.

Now, the modular division is the division in modular arithmetic.

Answering the question, a modular division problem like ordinary arithmetic is not used, division by 0 is undefined. For example, 6/0 is not allowed. In modular arithmetic, not only 6/0 is not allowed, but 6/12 under module 6 is also not allowed. The reason is that 12 is congruent with 0 when the module is 6.

Answer:

  • table: 14, 16, 18
  • equation: P = 2n +12

Step-by-step explanation:

Perimeter values will be ...

rectangles . . . perimeter

  1 . . . 14

  2 . . . 16

  3 . . . 18

__

The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...

  P = 2(6 +n) = 12 +2n

Your equation is ...

  P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.

_____

<em>Additional comment</em>

You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...

  y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles

Work out, giving your answer in its simplest form:<br> 4/7 divided by 2 1/3
kirill [66]

Answer:

12/49  

Step-by-step explanation:

First write 2 1/3 as a improper fraction, to do that, first multiply the 2 by the denominator, then add it with the 1, which will result in 7/3

when doing division of fraction you have to remember this, KFG

KFG: Keep Flip Change

you keep the first number or fraction, which is 4/7

then you flip the sign, so you change division in to multiplication

after that, you change or write the reciprocal of the second number or fraction, so 7/3 will be 3/7

Now the equation is

4/7 times 3/7, which is 12/49

Find the distance (-2,4) and (-5,-0)
ivolga24 [154]

Answer:

d=√65 units

Step-by-step explanation:

Using the distance formula :

d=√((−5)−(2))2+((0)−(4))2 units

d=√(−7)2+(−4)2 units

d=√49+16 units

d=√65 units
