A 500-foot weathertower used to measure wind speed has a guy wire attached to it 200 feet above the ground. The angle between the wire and the vertical tower is 47 degrees. Approximate the length of the guy wire to the nearest foot.

Answers

The length of the guy wire is 273.5 feet.

Trigonometric ratio show the relationship between the sides and angles of a right angled triangle.

Let d represent the length of the guy wire.

Using trigonometric ratios:

$sin(47)=(200)/(d) \n\nd=(200)/(sin(47)) \n\nd=273.5\ feet$

The length of the guy wire is 273.5 feet.

Answer: 293 feet

==========================================

Explanation:

See the attached image below. The information that the tower is 500 ft is never used. Focus solely on triangle ABD (ignore point C).

AB = 200

AD = x = unknown

angle ABD = angle B = 47 degrees

Use the cosine rule to help find x

---------

cos(angle) = adjacent/hypotenuse

cos(B) = AB/BD

cos(47) = 200/x

x*cos(47) = 200

x = 200/cos(47)

x = 293.255837127926

Rounding to the nearest foot, we get 293 feet as the answer.

In a survey, 9 out of 15 students named math as their favorite class.express this rate as a decimal

Answers

Answer: In decimal , it will be expressed as 0.6 .

Step-by-step explanation:

Since we have given that

Total number of students = 15

Number of students names as their favourite class = 9

First we write as a fraction, which is given by

$(9)/(15)\n\n=(3)/(5)$

Now , we will change it into decimal form using division, so it will be given by

$0.6$

Hence, our answer is 0.6.

9/15 reduced to 3/5 which is 0.6

miguel is earning extra money by painting houses. he charges a $200 dollar fee plus $12 per can of paint needed to complete the job. Write and use an equation to find how many cans of paint he needs for a $260 job

Answers

12c+200=260
I think this is right but you can double check too

Final answer:

To solve the problem, we set up a linear equation as $260 = $200 + $12x. After rearranging and solving the equation, we find that Miguel would need 5 cans of paint for a job worth $260.

Explanation:

The question pertains to solving a linear equation derived from a real-life scenario. In the given problem, Miguel has a set fee of $200 and then charges $12 per can of paint. If he has a job worth $260, to find how many cans of paint (represented by x) he'd need, we'll use the formula: total cost = set fee + (cost per can * no. of cans).

So, the equation in our case becomes: $260 = $200 + $12x.

To solve this equation, perform the following steps:
