The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 15, 30,60,... Find the 6th term.

Answers

Answer: 120, 240, 480

Step-by-step explanation:

It would appear that the numbers are increasing in multiples of 2.

15 * 2 = 30

30 * 2 = 60

The next 3 terms will therefore be:

60 * 2 = 120

120 * 2 = 240

240 * 2 = 480

Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?

Answers

Answer 9.5

you do the pyragtaham theory thing its A(squared) + B (squared) = C squared

you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5

The distance from the top of the ladder to the ground is 9.54 ft.

What is a right triangle?

"It is a triangle whose one of the angle is 90°"

What is hypotenuse?

"The longest side of the right triangle is called as hypotenuse."

What is Pythagoras theorem?

"For a right triangle,

c² = a ² + b²,

where c = hypotenuse and a, b are other two sides of right triangle."

For given example,

Gwendolyn placed a ladder against the side of her house.

This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.

Let 'a' be the hypotenuse of triangle, 'b' be the base and  'd' be the distance from the top of the ladder to the ground

⇒ a = 3 ft. and b = 10 ft.

Using Pythagoras theorem,

⇒ b² = a² + d²

⇒ 10² = 3² + d²

⇒ 100 = 9 + d²

⇒ d² = 91

⇒ d = 9.54 ft.

Therefore, the distance from the top of the ladder to the ground is 9.54 ft.

The time required to complete a job varies inversely as the number of people working. It took 4 hours for 7 electricians to wire a building. How long would it have taken 3 electricians?

A. 1 hour 43 minutes
B. 5 hours 15 minutes
C. 7 hours 30 minutes
D. 9 hours and 20 minutes

Answers

Answer:

9 hours and 20 minutes: b

Step-by-step explanation:

4*60=240

7x240=1680

1680/3=560

560= 9 h 20 m

The time required when 3 electricians are working is 9 hours and 20 minutes.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The time required to complete the job varies inversely with the number of people working.

This means that if the number of people working decreases, the time required to complete the job will increase.

We can use the formula for inverse variation to solve the problem:

t = k/n

where t is the time required to complete the job, n is the number of people working, and k is a constant of proportionality.

We can find k by plugging in the given values:

4 = k/7

k = 28

Now we can use the formula to find the time required when 3 electricians are working:

t = 28/3

t ≈ 9.33 hours

Converting this to hours and minutes, we get:

t ≈ 9 hours and 20 minutes

Thus,

The time required when 3 electricians are working is 9 hours and 20 minutes.

The park covers over one million acres. The park is open year-round and more than two million people visit each year. The terrain in the park varies from tall mountains to flat prairies. The mountains in Glacier National Park are part of the Rocky Mountain range. They were formed long ago when tectonic plates below the earth's surface collided and caused the land to rise. These mountains are now home to animals such as bighorn sheep, marmots, and mountain goats. There are numerous types of trees near the base of most of the mountains, but the numbers and types of trees decrease as the elevation of the mountains increases. Visitors to the mountains can hike on the trails in the summertime and cross-country ski on the slopes in the wintertime. In contrast to the high mountaintops, the prairies in Glacier National Park are found in low to mid-elevation areas. These wide, open spaces contain a variety of plants and animals.
