What is the area in square centimeters of the trapezoid below​

What Is The Area In Square Centimeters Of The Trapezoid Below

Answers

Answer 1

Answer:

39.6 cm²

Step-by-step explanation:

The formula for the area of a trapezoid is given as:

Area of a Trapezoid = 1/2(a + b) h

Where, from the question:

a = 8.9 cm

b = 5.5 cm

h = 5.5cm

Hence,

1/2 (8.9cm + 5.5cm) × 5.5cm

= 1/2 × 14.4 cm × 5.5 cm

= 39.6 cm²

Area of the Trapezoid = 39.6 cm²

Answers

Answer:

t ≤ 10

Step-by-step explanation:

To solve the inequality, simplify it.

-3t + 9 ≥ -21

Subtract 9 from both sides.

-3t ≥ -30

Divide by -3. When dividing by a negative, flip the inequality sign.

The answer is C, t ≤ 10.

Thats common sense

Answer:

Step-by-step explanation:

Computer languages love this kind of question. You could run it a million times and the computer would bring back an answer in under 10 seconds.

Let us suppose that 4 is the correct answer for all 5 questions.

Run the simulation 1000000 times. There is only 1 answer that is acceptable

select a random number from 1 to 4

do this 5 times

If all five random numbers are 4 then add 1 to counter which keeps track of the number of times 4 was chosen 5 times (it will be pretty small).

End by displaying the number of times 4 was chosen 5 times

Divide by 1 million.  

In running the simulation, I described using Delphi it ran the simulation in under 1 second. That is, took the test 1 million times.

I'm going to save this answer and if I can edit the  question I'll tell you what I got. If not, I suppose I could put it in a comment.

The experimental answer I got was 993 which is awfully close to 1/1000 which is approximately the theoretical answer. So my simulation that I described will work really well.

The theoretical answer is

1/4  *  1/4  * 1/4 * 1/4 *1/4 = 1 / 1024  So actually 1/1000 (which my simulation nearly got) is really kind of close.

There are other ways of doing this simulation.

The triangle below has a perimeter of 20. Solve for x​

Answers

Answer:

x = 5

Step-by-step explanation:

Given that,

First side of a triangle = x+2

The second side of a triangle = 8

The third side of a triangle = x

We know that, perimeter is equal to the sum of all sides. So,

x+2+x+8 = 20

2x+10 = 20

2x = 10

x = 5

Hence, the value of x is equal to 5.

Write the equation of a circle with a center of (1,-2) and radius of 4.

Answers

Answer:

(x - 1)^2 + (y + 2)^2 = 4^2

Step-by-step explanation:

The standard equation of a circle of radius r with center at (h, k) is

(x - h)^2 + (y - k)^2 = r^2

Replacing h with 1, y with -2 and r with 4, we get:

(x - 1)^2 + (y + 2)^2 = 4^2

A trapezoid has a height of 6 inches, an area of 120 square inches, and one base measuring 13 inches. Find the length of the other base. ​

Answers

Answer:

27

Step-by-step explanation:

Givens

b1 = 13

b2 = ?

h = 6

Area = 120

Formula

Area = (b1 + b2) * h/2         Multiply by 2

2Area = (b1 + b2)*h           Divide by h

2Area/h = b1 + b2              Subtract b1 from both sides

2Area/h - b1 = b2

Solution

2*120 / 6 - 13 = b2

40 - 13 = b2

b2 = 27

It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

A westbound train travels 16 miles per hour slower than the eastbound train. If two trains are 800 miles apart after 5 hours what is the rate of the westbound train?

Answers

Answer:

6

Step-by-step explanation:

The rate can be calculated as follows

x + x -16

2x-16

(2x-16)×5

10x - 80= 800

10x = 300-80

10x, = 220

x = 220/10

= 22

22-16

= 6 mph

Hence the rate of the west bound tsin is 6mph

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

Then

g(x + 3)² is the graph of f(x) translated 3 units left

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Then

g(x) = g(x + 3)² - 7 is the graph of f(x)

Translated 3 units left and 7 units down

Area = 1/2( 8 + 14) 5 = 1/2× 22 × 5 = 55 ft^2

Find the area of the trapezoid.

Answers

Answer:

78 ft squared

Step-by-step explanation:

To find the area of trapezoid, we could use this formula:

.5*height*(sum of bases)

We know both the base lengths. They are 10 and 16 ft.

The height can be found by looking at that right triangle whose base is (16-10) ft or 6 ft.

So we want to find the height which is opposite the 45 degree angle and we have the adjacent side's measurement of 6ft.

This has the tangent ratio written all over it since tangent of an angle is opposite side's measurement over adjacent side's measurement.

tan(45)=height/6

1=height/6

6=height

6ft=height

The answer is:

.5*height*(sum of bases)

.5*6 ft*(10 ft+16 ft)

3 ft(26 ft)

78 ft squared

Note: That one right triangle is an isosceles right triangle so we didn't need trigonometry.

What is the absolute maximum or minimum of f(x) = 3x^2-5x-9

Answers

Answer:

Absolute minimum / vertex = (5/6,-133/12)

Step-by-step explanation:

Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)

(5/6,-133/12) You have to use the formula x=-b/2a
