Answer:

Step-by-step explanation:

None of these choices is correct.

3y = 8 is an equation, not an expression. It states that "y is 8 divided by 3," which again is an equation.

dalvyx [7]

Answer:

1767.1 inches cubed

Step-by-step explanation:

The volume of a ball, or a sphere, is: $V=\frac{4}{3} \pi r^3$ , where r is the radius.

Here, the radius is r = 7.5. So, plug in this value: $V=\frac{4}{3} \pi *(7.5)^3=562.5\pi$

562.5 pi is about 1767.1 inches cubed.

Thus, the volume is 1767.1 inches cubed.

Hope this helps!

The tee for the sixth hole on a golf course is 305 yards from the tee. On that hole, Marsha hooked her ball to the left, as sket

EleoNora [17]

Answer:

Correct answer is option D. 96.4 yd.

Step-by-step explanation:

Please refer to the attached figure for labeling of the given diagram.

ABC is a triangle with the following labeling:

A is the hole, B is the Tee and C is the point where the ball is.

Sides are labeled as:

$a =255\ yd\\c = 305\ yd\\\angle B =17^\circ$

To find:

Side $b = ?$

Solution:

Here, we have one angle and two sides . Third side of the triangle is to be found opposite to the given angle.

We can use cosine formula here to find the value of the unknown side.

$cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}$

Putting all the values:

$cos 17 = \dfrac{255^{2}+305^{2}-b^{2}}{2\times 255\times 305}\\\Rightarrow 0.956 = \dfrac{65025+93025-b^{2}}{155550}\\\Rightarrow 148753.2= 158050-b^{2}\\\Rightarrow b^{2}= 158050-148753.2\\\Rightarrow b^{2}= 9296.795\\\Rightarrow b= 96.42\ yd$

So, the distance between the Ball and hole is 96.42 yd

Correct answer is option D. 96.4 yd.
