The correct answer is n=-48

Subtract 3 from both sides

$\frac{N}{4}$ = -12

Multiply both sides by 4

$\frac{4n}{4}$ =4(-12)

Simplify

n=-48

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.

A pilot traveling 175 miles per hour encounters a head wind of 35 knots. If there are 1.15 knots per mph, what will her true spe

KonstantinChe [14]

Since one knot is 1.15 mph.
We multiply 35 time 1.15, which equals 40.25 mph.
Then we subtract. 175 - 4.25 = 134.75
Round, and you'll get 135mph
Therefore, your answer is 135mph

144kg in the ratio of 9:8:7

ANEK [815]

Step-by-step explanation:

Hey there!

Given;

Ratio = 9:8:7

Let "x" be the common factor. So,

9x+8x+7x = 144

or, 24x = 144

or, x = 144/24

or, x= 6

It's like;

= 9*6:8*6:7*6

= 54:48:42

Therefore, their ratio is 54:48:42.

Hope it helps...

Simplify 24x5y2z10 / 16x3y z5 Show your work.

svetoff [14.1K]

Answer:

3/2 x^2 y z^5

Step-by-step explanation:

24x^5y^2z^10 / 16x^3y z^5

split into pieces

24/16 * x^5/x^3 y^2/y z^10/z^5

when dividing exponents with the same bases, we subtract the exponents

3/2 x^(5-3) y^(2-1) z^(10-5)

3/2 x^2 y^1 z^5
