That means legthn+lgnth +width+width

that is the perimeter formula for a rectangle or the measure around a rectangle

it can be written as (l-legnth)
perimiter=2l+2w or

Answer:

  12.0 cm

Step-by-step explanation:

Use the formula for the volume of a cylinder. Fill in the given values and solve for the height.

  V = πr^2h

  1846 cm^3 = π(7 cm)^2·h

  h = 1846/(49π) cm ≈ 12.0 cm . . . . . . divide by the coefficient of h

The height of the can is about 12.0 cm.

Answer:

z = 55.15432893

x = 59.61543424

y = 22.5166605

Step-by-step explanation:

To find length "z" you will have to use SOHCAHTOA.

Labelling the triangle will show us that the side marked "z" is the hyp and the side marked 39 is the opp.

sin 45 = \frac{39}{z}

z sin 45 = 39

         z  = \frac{39}{sin45}

         z = 55.15432893

Using Pythagoras' theorem, you can find that the adj = 39

In the other triangles POV, the adj is actually the opp.

Therefore, use tangent to find y.

tan 60 = \frac{39}{adj}

y tan 60 = 39

           y = \frac{39}{tan60}

           y = 22.5166605

Use Pythagoras's Theorem to find x.

23^{2} + 55^{2} = x^{2}\\\sqrt{23^{2} + 55^{2}}  = x\\59.61543424=x

While on a road trip, Steve drove 300 miles in 5 hours. After stopping for gas, he drove an additional 120 miles in 2 hours. Doe
bija089 [108]

Answer:

The given situation is in direct variation.

The dependent variable is the distance covered and the independent variable is the number of hours.                

Step-by-step explanation:

We are given the following information in the question:

Steve drove 300 miles in 5 hours.

After stopping for gas, he drove an additional 120 miles in 2 hours.

We calculate the ratios and if these ratios are equal then, we can say that the situation represent a direct variation.

For direct variation, the equation is of the form y = kx that is , we can write,

\displaystyle\frac{y}{x} = k

To check the ratio:

\displaystyle\frac{300}{5} = \frac{300+120}{5+2} =\frac{420}{7} = 60

Thus, the given situation is in direct variation.

The dependent variable is the distance covered and the independent variable is the number of hours.
