13 < 4n - 14.4 ?

Answers

13 < 4n - 14.4

13 + 14.4 < 4n - 14.4 + 14.4

27.4 < 4n + 0

27.4 < 4n

27.4 / 4 < 4n / 4

6.85 < 4n / 4

6.85 < n * (4 / 4)

6.85 < n * (1)

6.85 < n

Set A contains 35 elements and set B contains 22 elements. If there are 40 elements in (A ∪ B) then how many elements are in (A ∩ B)?

Answers

Answer:

17

Step-by-step explanation:

The computation of the number of elements are in (A ∩ B) is shown below;

Given that

Set A contains 35 elements

And, set B contains 22 elements

Now if there are 40 elements in (A ∪ B)

So, the number of elements are in (A ∩ B) is

= 35 + 22 - 40

= 17

The great pyramid in Egypt has a square base with a side length of 250 ft. It’s height is twice the size of the length of a side of its base. What is the Volume of the great pyramid?

Answers

Answer:

Step-by-step explanation:

base b = 250 ft

Segment AB and segment CD intersect at point E. Segment AC and segment DB are parallel. If m∠A=41m∠A=41o and m∠D=56m∠D=56o, find the m∠AECm∠AEC.

Answers

Answer:

m∠AEC = 83°

Step-by-step explanation:

∠C and ∠D are alternate angles and are congruent because segment AC is parallel to DB

Therefore, m∠C = 56°

Sum of measures of angles of a triangle is 180.

So,  m∠A + m∠C + m∠AEC = 180  

41 + 56 + m∠AEC = 180

m∠AEC  + 97 = 180

m∠AEC = 83°

After 10% tax, the phone cost $220. What was the original price?​

Answers

Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!

Answers

Answer:

SAS (side angle side)

Step-by-step explanation:

Answer:

because the corresponding angles are congruent, the triangles are congruent through CPCTC. If two sides are congruent and an included angle, then the triangles are congruent through the SAS postulate. And if two sides and a non-included angle are congruent then the triangles are congruent through the AAS postulate. Any way of looking at this proves congruency through various postulates, therefore the trianlges are congruent.
