A short-wave radio antenna is supported by two guy wires, 150 ft and 180 ft long. Each wire is attached to the top of the antenn

a and anchored to the ground at two anchor points on opposite sides of the antenna. The shorter wire makes an angle of 65° with the ground. How far apart are the anchor points? (Round your answer to the nearest foot.)

The distance between the anchor points of the two guy wires holding radio antenna is 181 feet (to the nearest foot)

<h3>How to determine the distance between the two anchor points of the guy wire</h3>

The problem will be solved using SOH CAH TOA

let the distance between the 150 ft long guy wire and the radio antenna be x

let the distance between the 180 ft long guy wire and the radio antenna be y

cos 65° = x / 150

x = cos 65° * 150

x = 63.39 ft

The height of the antenna

sin 65° = height of antenna / 150

height of antenna = sin 65 * 150

height of antenna = 135.95

using Pythagoras theorem

(length of guy wire)² = (height of the antenna)² + (anchor distance)²

(anchor distance)² = 180² - 135.95²

anchor distance = √(180² - 135.95²)

anchor distance = 117.97

The anchor points distance apart

= 63.39 + 117.97

= 181 (to the nearest foot)

There are 230 calories in 4 ounce of a type of ice cream. How many calories are in 6 ounces of paper ice cream
serious [3.7K]

Answer:

345 calories.

Step-by-step explanation:

We have been given that there are 230 calories in 4 ounce of a type of ice cream.

First of all let us find calories per ounce ice-cream by dividing 230 by 4.

\text{Number of calories per ounce ice-cream}=\frac{230}{4}

\text{Number of calories per ounce ice-cream}=57.5

Therefore, the ice-cream contains 57.5 calories per ounce of ice-cream.

Let us find amount of calories in 6 ounces of ice-cream by multiplying number of calories per ounce by 6.

\text{Amount of calories in 6 ounces of ice-cream}=57.5\times 6

\text{Amount of calories in 6 ounces of ice-cream}=345

Therefore, there are 345 calories in 6 ounces of ice cream.

Last time, one out of every 4 students in our class was absent. this time, after jen came back only one out of every 5 students
statuscvo [17]
Let x be the number of students in the class the
 the number of students in the class when 1 in 4 are absent = x - 0.25x  = 0.75x
After Jen returns  there are x - 0.2x = 0.80x so we have the equation
0.75x + 1 = 0.80x
0.05x = 1
x = 1 / 0.05 = 20 Answer

So there are 20 students in the class.
No. students not here today = 0.80 * 20  = 16  Answer

Solve the system by the substitution. 8x-3y=-22 y=5x+19
LiRa [457]
Substitute y in 8x - 3y = -22.

8x - 3(5x + 19) = -22
Simplify.
8x - 15x - 57 = -22
Simplify.
-7x - 57 = -22
Add 57 to both sides.
-7x = 35
Divide both sides by -7.
x = -5

Substitute x in y = 5x + 19.

y = 5(-5) + 19
y = -25 + 19
y = -6

The solution is (-5, -6).

Claudia is making a candle by pouring melted wax into a mold in the shape of a cylinder. The radius of the cylinder’s base is 4
Sati [7]

The formula of a cylinder is 2πr (r+h)

2π4 (4+9)

8π (13)

25.13 (13)

326.73

Cubes: area = a^3

3x3x3 = 27

326.73 / 27 = 12.1

Claudia would need to buy 13 wax cubes to fil the candle.

hope this helps k12 students :)
