Answer:

Step-by-step explanation:

So this gives us a few clues. The numbers all have an equal value between them, and the fourth and fifth are 27 and 32 respectively. So how much is between these two?

5, so since you add five to go from fourth to fifth, you subtract to go backwards. So then the third is 27-5 = 22 and so on, can you figure it out from there? just subtract 5 however many more times is needed.

A. x=the cost of one lunch. 60.25=5x+3(x-5.25)

b. 60.25=5x+3x-15.75 60.25+15.75=8x-15.75+15.75

76=8x 76/8=8x/8 9.50=x

A lunch is $9.50. If you are not sure, check my answers. Hope this helped.

There are 3/4 as many boys as girls in a class of 5th graders if there are 35 students in the class how many are girls?

Writing an equation is the easiest way to figure this out.
b = boys, g = girlsb = 3/4g35 students = g + b35 = g + 3/4g35 = 7/4g35/7/4 = g20 girls35 - 20 = b or 3/4(35) = b15 boys

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:

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