What is the area, in square centimeters, of the isosceles trapezoid below?
5-3 cm
4.2 cm
13.5 cm

Answers

Answer 1

Answer:

both triangles area:

4.2 x 8.2 = 34.44

you don’t need to divide by two cause there’s two triangles anyways.

also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)

rectangle:

4.2 x 5.3 = 22.26

the total area is 56.7cm squared

Answers

Answer:

Angle A = 77, Angle B = 41

Step-by-step explanation:

Triangles add up to 180 degrees. Your equations would be 62 + (2x-5)+x=180.

Simplify: 57 + 3x = 180

Solve for x: 3x = 123

X = 41.

Then insert X to find angle A.

A. Discounted price

B. Total price

C. Tax

D. Subtotal

Answers

Answer:

Total price

Step-by-step explanation:

Total Price means the full purchase price of a consumer item, excluding sales tax and container deposit. This is the FINAL price.

The final price after all percentages are taken off and taxes are added up is known as the Total price. The correct answer is option B.

What is the total price?

The final price after all percentages are taken off and taxes are added up is known as the Total price.

Let us understand the total price with an example, the cost price of the TV is $1000 without any taxes. The sales tax is 10% levied on the product and custom duty is 20%.

The total price of the product will be calculated as:-

Sales tax = 1000 x ( 10 / 100 ) = $100

Custom duty = 1000 x ( 20 / 100 ) = $200

The total cost will be calculated as:-

Total cost = 1000 + 100 + 200

Total cost = $1300

Therefore, the correct option is B.

Side BC is 4 meters long. Side CD is twice the length of the side BC. What is the length of side LM. Explain your reasoning.

Answers

Answer:

LM = 18

Step-by-step explanation:

BC = 4

CD is twice that, so CD is 8

Now, remembering that the area of ABCD = 32 and JKLM = 72, divide 72 by 32.

You get 2.25. This is how much bigger JKLM is than ABCD.

Using that, multiply the length of CD (which is 8) by 2.25 to get the length of LM.

You'll get 18.

The eighth term of an arithmetic sequence is double the value of the third term. The fifth term is equal to 14. Determine the first term and the common difference of the sequence.

Answers

Answer: first term = 6

Common difference = 2

Step-by-step explanation:

Eight term =a +(n-1)d = a +(8-1)d = a + 7d

Third term = a+(n-1)d = a + (3-1)d =a + 2d

a + 7d = 2(a + 2d)

a + 7d = 2a + 4d

7d - 4d = 2a - a

a = 3d

The fifth term is equal to 14. This is:

a + 4d = 14

Put the value of a into the equation here

3d + 4d = 14

7d = 14

d = 14/7

d = 2

Recall that a + 4d = 14

a + 4(2) = 14

a + 8 = 14

a = 14 - 8

a = 6
