Answer:

The answer is <u>38 yards</u>.

Step-by-step explanation:

Given:

30 yards of fabric is needed to make 10 dresses.The fabric roll stamped 35 meters.

Now, to find the yards (round to the nearest yard).

The unit rate:

1 metre = 1.09 yard.

So, as the fabric roll stamped 35 metres.

Thus, by multiplying 35 meters with 1.09 yard we get the yards:

35\times 1.09

=38.15\ yards.

So, the nearest to yard is 38 yards.

Therefore, the answer is 38 yards.

The law of cosines is used for this purpose. It tells you
  c² = a² + b² - 2ab×cos(C)
Solving for the angle C gives
  C = arccos((a² + b² - c²)/(2ab))
  C = arccos(( 17² + 15² - 19²)/(2×17×15))
  C = arccos(153/510)
  C ≈ 72.5424°

The measure of the angle opposite the longest side is about 73°.

Number 9 need help mathhh
Sergio039 [100]

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3

<h3>How to get the volume of the sphere?</h3>

For a sphere of radius R, the volume is given by the formula:

V = (\frac{4}{3})*3.14*R^3

In this case, we can see that the diameter is 9 cm, then the radius is half of that:

R = 9cm/2 = 4.5cm

Now that we know the radius, we can replace it on the volume formula to get:

V = (\frac{4}{3})*3.14*(4.5cm)^3 = 381.51 cm^3

Solve for x I need help please
olchik [2.2K]
Check the picture below.

bear in mind that, a perpendicular line stemming from the right-angle like so, creates three similar triangles, a large one, containing the other two smaller ones, a medium and a small.

so.. .we can just use the medium and small proportions.

solve for "x".
