Sergio039 [100]3 years ago
8 0

Answer:

Step-by-step explanation:

The given figure is a trapezoid. The perimeter of a plane figure is expressed as the the distance around the figure. Therefore

Perimeter = a2 + b2 + a1 + b1

Perimeter = 4.7 + 5.8 + 8.5 + 6.89 = 25.89 feet

The formula for determining the area of a trapezoid is expressed as

Area = 1/2(a + b)h

Where

a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.

h represents the height of the trapezoid.

From the diagram,

a = 4.7 feet

b = 8.5 feet

h = 5.8 feet

Area = 1/2(4.7 + 8.5)5.8

Area = 1/2 × 13.2 × 5.8

Area = 38.28 feet²

An isosceles trapezoid was broken into a rectangle and two triangles. What are the base and height of one of the triangles?
Serga [27]

Answer:

base = 2 m; height = 6 m

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

Given the information:

  • base of 8 meters
  • height of 6 meters
  • top side length of 4 meters.

=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters

=> the base of the triangles:

= (the base of the trapezoid - the top side length) / 2

= (8-4)/2

= 2

So the base and height of one of the triangles : base = 2 m; height = 6 m

Hope it will find you well.

A hockey player earns 2 million in 2015 during the next 10 years to earnings increase 5% each year write an explanation growth m
DiKsa [7]

Answer:

Y(T) = 2(1.05)^T

Step-by-step explanation:

The player's salary, in millions of dollars, t years after 2015, is given by an equation in the following format:

Y(T) = Y(0)(1+r)^T

In which Y(0) is his initial salary and r is the growth rate, as a decimal.

A hockey player earns 2 million in 2015 during the next 10 years to earnings increase 5%

This means, respectively, that:

Y(0) = 2, r = 0.05

So

Y(T) = Y(0)(1+r)^T

Y(T) = 2(1+0.05)^T

Y(T) = 2(1.05)^T

Your boss hands you a memo with a summary of the monthly data.

Functions are used to represent tables and equations

  • The function that represents the number of imports is f(x) = 2x
  • The function that represents the number of exports is f(x) = 2 + x

<h3>How to determine the import function</h3>

From the table, we can see that the values of the import is twice the number of months

This is represented as:

y = 2x

Rewrite as a function

f(x) = 2x

Hence, the function that represents the number of imports is f(x) = 2x

<h3>How to determine the export function</h3>

From the table, we can see that the values of the export is two more than the number of months

This is represented as:

y = 2 + x

Rewrite as a function

f(x) = 2 + x

Hence, the function that represents the number of exports is f(x) = 2 + x

For what value of a does the equation 3(2x-a)=2(3x+12) have infinitely many solutions to x
shtirl [24]

Answer: a = -8

3(2x - a) = 2(3x + 12)

⇔ 6x - 3a = 6x + 24

⇔ - 3a = 24

⇔ a = -8
