A 103-foot wire is used to support a utility tower. It runs from the tower to the ground and forms a 24° angle with the ground.

Answers

Answer:

Height of Tower = 41.8901 ft

Base to Ground Wire = 94.0905 ft

Step-by-step explanation:

So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.

Here are the equations:

sin(24)=[tex]\frac{h}{103}[/tex]

cos(24)=[tex]\frac{h}{103}[/tex]

The base of the utility tower from the location where wire is attached to the ground is 94.09 feet and the wire attached to the tower at a height of 41.89 feet.

What is right angle triangle property?

In a right angle triangle ratio of adjacent side to the hypotenuse side is equal the cosine angle between them.

[tex]\cos\theta=\dfrac{a}{c}[/tex]

Here, (a) is the adjacent side, (c) is the hypotenuse side and [tex]\theta[/tex] is the angle made between them.

a) The value from the base of the utility tower from the location where wire is attached to the ground

The length of the wire is 103 foot. This is the hypotenuse side of triangle made by the wire, tower, and ground.

The angle between the wire (hypotenuse side) and ground (adjacent side) is 24 degrees. Therefore, the cosine angle can be given as,

[tex]\cos (24^o)=\dfrac{a}{103}\\0.9135\times103=a\\a=94.09\rm ft[/tex]

b) The wire attached to the tower at a height of __ feet.

In a right angle triangle ratio of opposite side to the hypotenuse side is equal the sine angle between them. Let the height of the tower (opposite side) is b ft. Therefore,

[tex]\sin(24^o)=\dfrac{b}{103}\\0.4067\times103=b\\b=41.89\rm ft[/tex]

Thus, the value from the base of the utility tower from the location where wire is attached to the ground is 94.09 feet and the wire attached to the tower at a height of 41.89 feet.

Scott is 72 inches tall and Chris is 185 centimeters tall how tall is Chris in inches?

Answers

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

On the windowsill is a plant that is 10 inches tall. It is growing 3 inches per
week. A second plant, which is 17 inches tall, is on the coffee table. It is
growing 2 inches per week. Eventually the two plants will be the same
height. How tall will the plants be? How many weeks will that take? *

Answers

Answer:18 days

Step-by-step explanation:

Here's a short table of heights:

day 0: height = 1

day 1: height = 1 + (1/2)(1) = 3/2

day 2: height = (3/2) + (1/3)(3/2) = 3/2 + 1/2 = 2

The pattern of heights is ...

(day, height) = (0, 1), (1, 1.5), (2, 2)

The plant is growing 1/2 its original height each day, so we can write the equation ...

h = 1 + d/2

We want to find the number of days (d) that result in a height of 10 (ten times the original height).

10 = 1 + d/2

9 = d/2 . . . . subtract 1

18 = d . . . . . multiply by 2

It took 18 days for the plant to grow to 10 times its original height.

Answer:

it would take 9 weeks for both of the plants to equally meet the same height which is 33 inches

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?

Answers

Answer:

[tex]\boxed {\boxed {\sf \$54.80}}[/tex]

Step-by-step explanation:

Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.

[tex]commission= commission \ rate * sales[/tex]

His rate is 4% and his sales are $1,370

[tex]commission= 4\% * \$1370[/tex]

Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.

4/100= 0.04 4.0 --> 0.4 --> 0.04

[tex]commission= 0.04* $1370[/tex]

[tex]commission = \$ 54.8[/tex]

Chris's commission is $54.80

4. What is the volume of the cone shown below?
Round to the nearest tenth.
5 ft.
d = 2 ft.

Answers

Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

What is volume?

Volume is the measure of the capacity that an object holds.

Formula for the volume of cone

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.
