Answer: See explanation

Step-by-step explanation:

Your question isn't complete but I'm assuming that you want to calculate the radius.

Circumference of a circle = 2πr

where Circumference = 18.9 meters

Radius = Unknown

π = 3.14

We then put the values into the formula which will be:

C = 2πr

18.9 = 2 × 3.14 × r

18.9 = 6.28r

r = 18.9 / 6.28

r = 3

The radius = 3 meters

Assuming you probably want to get the diameter, we multiply the radius by 2. This will be:

= 2 × 3

= 6 meters

X - 2y = -3<br> 2x + y = -1
bezimeni [28]

Answer:

y = 1

x = -1

Step-by-step explanation:

x - 2y = -3, then x = 2y - 3

2x + y = -1

substitute for x:

2(2y - 3) + y = -1

4y - 6 + y = -1

5y = 5

y = 1

x = 2 - 3 = -1

What was the total production of gasoline and kerosene combined (in Barrels)
Elina [12.6K]

The amount of kerosene and gasoline produced is an illustration of equations.

<em>44.4 million barrels of gasoline and kerosene are produced</em>

Let

<em />x \to<em> Proportion of kerosene</em>

<em />y \to<em>  Proportion of Gasoline</em>

<em />

So:

x = 40\%

y = 34\%

Total = 60\ million ---- total barrels produced

The amount of Kerosene produced is:

Kerosene =x \times Total

Kerosene =40\% \times 60\ million

Kerosene = 24\ million

The amount of Gasoline produced is:

Gasoline  =y \times Total

Gasoline  =34\% \times 60\ million

Gasoline  =20.4\ million

So, the total production of both is:

Total = Kerosene + Gasolene

Total = 24\ million + 20.4\ million

Total = 44.4 million

<em>Hence, 44.4 million barrels of gasoline and kerosene are produced</em>
