Brittany and Will each made a triangular sign with an area of 8 square feet. The base of Brittany's triangle is half as long as the base of Will's. How do the heights of the triangles compare?

Answers

Answer:

the length of Brittany's triangular sign is 1/2 the length of Will's

Step-by-step explanation:

The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

How do the heights of the triangles compare?

Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.

For Brittany's triangle:

A = ¹/₂b₁h₁ = 8

For Will's triangle:

A = /₂b₂h₂ = 8

We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle

b₁ = ¹/₂b₂

Now, let's find the relationship between the heights of the triangles:

From the equations above, we can see that:

h₁ = 16 / b₁

h₂ = 16 / b₂

Recall; b₁ = ¹/₂b₂

h₁ = (2 x 16) / b₂

h₂ = 16 / b₂

So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?

Answers

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

How many more people live in Cheyenne than in Laramie?

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.

Answers

Answer:

i dont know what to say, bro

Step-by-step explanation:

just kidding $72.52

Step-by-step explanation:

A gallon of gasoline costs $2.96.

Your car can travel the distance on each gallon of gasoline = 28.8 miles

Your length of the trip =  miles =

First we calculate the total use of gasoline on the trip.

∵ By 1 gallon gas of gasoline you can cover the distance = 28.8 miles

∴ to take  miles trip gasoline used =

=

=

= 24.5 gallons

Since the cost of one gallon gasoline = $2.96

∴ The cost of 24.5 gallons of gasoline = 24.5 × 2.96

                                                               = $72.52

You spend $72.52 on gasoline for the trip of  miles.
