2. Ken combined a triangle and a trapezoid to
make a parallelogram. If the area of the triangle
is 12 in. 2 and the area of the trapezoid is 24 in.2
what is the area of the parallelogram? Explain.

The middle of the upper half of a set of organized data is called the upper quarter.

We can divide the organized data in two halfs or in 4 quartiles (the interquartile range), where each quartile contains 25% of the data.

Such that each of the two halfs would be divided into two quartiles.

The middle of the upper half (where the third quartile ends and the fourth starts) is called the upper quarter.

So, concluding, the middle of the upper half of a set of organized data is called the upper quarter.

Answer:

A. $6360, B. He doesn't have enough money.

Step-by-step explanation:

Answer:

This answer is for only part A

1tv=$795

8 x 795 = 6,360

Answer: Area of the rectangular room = length x Breadth

Length= 18 and Breadth = 12

Therefore the Area required to cover the floor = 18 * 12 = 216 ft2

The area of the rectangular room is given by the equation A = 216 feet²

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

The length of the rectangular room = 18 feet

The width of the rectangular room = 12 feet

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Area of the rectangular room = 18 feet x 12 feet

On simplifying the equation , we get

Area of the rectangular room A = 216 feet²

Therefore , the value of A is 216 feet²

Hence , the area of the rectangular room is 216 feet²

Answer:

75% chance

Step-by-step explanation:

Probability always adds to 1.00

Letter grades are always in the form A, B, C, D...

The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.

#LearnWithBrainly

The probability of getting a grade above a C is 0.75, or 75%.

We have,

To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.

Given:

Probability of getting an A (P(A)) = 0.25

Probability of getting a B (P(B)) = 0.50

A grade above a C includes grades of A and B.

Therefore, the probability of getting a grade above a C (P(above C)) is:

P(above C) = P(A) + P(B)

P(above C) = 0.25 + 0.50

P(above C) = 0.75

Thus,

The probability of getting a grade above a C is 0.75, or 75%.

Answer: y=7/2 in decimal form 3.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2-4*y-(-12)=0

Pull out like factors :

  14 - 4y  =   -2 • (2y - 7)

  Solve  :    2y-7 = 0  

Add  7  to both sides of the equation :  

                     2y = 7

Divide both sides of the equation by 2:

                    y = 7/2 = 3.500

........

Step-by-step explanation:

a) Tangent equals sine divided by cosine.  Therefore:

tan(-t) = sin(-t) / cos(-t)

b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):

tan(-t) = -sin(t) / cos(t)

tan(-t) = -tan(t)

c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function).  Therefore, y = tan(t) is symmetric about the origin.

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute = [tex]\frac{60}{20} = 3[/tex]

Formula for linear speed is given as:

[tex]v=\dfrac{2\pi}{60}\cdot r\cdot RPM[/tex]

Where [tex]r[/tex] is the radius of circular path and

[tex]RPM[/tex] is the number of revolutions per minute.

[tex]v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}[/tex]

Therefore, the linear speed is 2.983 ft/sec.

I want you first to get rid of the -4-12 and be done with it so here are the steps:
Rule: If negative subtract a negative, that shall be an addition problem with the larger number's symbol.

In this case, we need to add 4 and 12 together and include the negative symbol in front of the answer.

That shall be -16

Our Question now:
9+8/-16

So do 9+8 which is 17.

Our question now:

17/-16

Your answer is an improper fraction so you could change it to a mixed number or you could simply divide 17 and -16 to get a negative decimal.

Here are the possible answers:

Answer:

Closet #1.

Step-by-step explanation:

Closet #1 is 4x5x8, right? so, 4x5=20, and 20x8=160 feet. Closet #2 is 6x3x8, and 6x3 is 18. That's already less than 20 even before we multiply by 8. So, the answer to your question is Closet #1.

Answer:

Answer: The first closet is larger.

Step-by-step explanation:

Closet #1

V = l × w × h

V = 4 ft. × 5 ft. × 8 ft.

V = 160 cu. ft.

Closet #2

V = l × w × h

V = 6 ft. × 3 ft. × 8 ft.

V = 144 cu. ft.

Compare the size of the closets

160 cu. ft. > 144 cu. ft.

Answer: The first closet is larger.
