Answer: Density = 0.23 tons per cubic meter.

Step-by-step explanation:

Formula : Density=\dfrac{Mass(in \ ton)}{Volume (in\ m^3)}

1 ton = 32000 ounces

⇒ 1 ounce = 0.00003125 ton

⇒  7 ounces = 7(0.00003125)=  0.00021875 ton

1 gallon = 0.00378541 cubic meter

2.5 gallons = 0.009475 cubic meter

Density= \dfrac{0.00021875}{0.009475}\text{ tons per cubic meter}

\dfrac{21875}{94750}\text{ tons per cubic meter}\approx0.23\text{ tons per cubic meter}

Hence, Density = 0.23 tons per cubic meter.

Find the center, vertices, and foci of the ellipse with equation 3x2 + 8y2 = 24
Sveta_85 [38]

Answer:

The center is at (0,0)

The vertices are at ( ( ±2 sqrt(2),0)

foci are  ( ±sqrt(5),0)

Step-by-step explanation:

3x^2 + 8y^2 = 24

Divide each side by 24

3x^2 /24 + 8y^2/24 = 24/24

x^2/8  + y^2 /3 = 1

The general equation of an ellipse is

(x-h)^2/  a^2  + (y-k)^2 / b^2  = 1

a>b   (h,k) is the center

the coordinates of the vertices are ( ±a,0)

the coordinates of the foci are  ( ±c,0), where  ^c2=a^2−b^ 2

The center is at (0,0)

a = sqrt(8) = 2sqrt(2)

The vertices are at ( ( ±2 sqrt(2),0)

c = 8 - 3 =5

foci are  ( ±sqrt(5),0)

The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals
statuscvo [17]

Answer:

The number of additional shots on goal to score 3 more goals is 36

Step-by-step explanation:

Let

x ----> the number of goals scored

y ---> the number of shots on goal

we know that

\frac{x}{y}=\frac{4}{48} ----> equation A

so

For x=3

substitute the value of x and solve for y

\frac{3}{y}=\frac{4}{48}

y=\frac{48}{4}(3)

y=36

therefore

The number of additional shots on goal to score 3 more goals is 36
