For the conversion of 0.0003140 kilograms to ounces, the conversion factors are 103 grams per kilogram, 1 pound per 453.6 grams

Ksenya-84 [330]

The correctly expressed answer is 1.108 × 10⁻² ounces.

<u><em>Explanation</em></u>

The conversion factors are 10³ grams per kilogram, 1 pound per 453.6 grams and 16 ounces per pound.

So, 0.0003140 kilograms = $(0.0003140*10^3)grams = 0.3140 grams$

Now, 1 pound = 453.6 grams

⇒ 1 gram = $(\frac{1}{453.6}) pound$

So, 0.3140 grams = $(0.3140* \frac{1}{453.6})pound$

Now,

$(0.3140*\frac{1}{453.6})pound\\ \\=(0.3140*\frac{1}{453.6}*16 )ounces\\ \\= 0.01108ounces\\ \\= 1.108*10^-^2 ounces$

So, 0.0003140 kilograms = 1.108 × 10⁻² ounces.

Slove all of it please 100 points

Katyanochek1 [597]

Answer:

Step-by-step explanation:

5x+y-7=0 isolate y

y=-5x+7 (m=-5,b=7)

9x+7y-14=0

7y=14-9x ( divide both sides by 7)

y=-9x/7 +14/7

y=-9/7 + 2 (m=-9/7, b=2)

x+y=1000

4x+3y=3600 ( multiply the first equation by 3 to eliminate y)

3x+3y=3000

4x+3y=3600 ( subtract the two equations)

3x+3y-(4x+3y)=3000-3600

3x+3y-4x-3y=-600

-x=-600

x=600 ( substitute x in the equation)

x+y=1000

600+y=1000

y=1000-600=400

check : x+y=1000 , (600+400)=1000

check : 4x+3y=3600 = (4(600)+3(400))=2400+1200=3600

how many tickets are sold :

adults x=600/4=150

kids (y)=400/3=133 tickets+1 dollars left

unless( x represent kids then x=200, y represent adult = 100)

Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f

AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = $\frac{1}{2}$ feet

∴ 18 feet length of the room = $\frac{18}{2}=9$ inches

Similarly 14 feet width of the room = $\frac{14}{2}=7$ inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.
