HELP HELP HELP HELP FIND THE VALUE OF X

Mathematics
1 answer:
aalyn [17]3 years ago
8 0

Answer:

x=9

Step-by-step explanation:

The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.

90+5x+5x=180

add the x values together

90+10x=180

subtract 90 from both sides

10x=90

divide both sides by 10

x=9

BC <span>≅ EF (CPCTC)

Set the two side lengths equal to each other.

38.4 = 5x - 10.6

Isolate the x. Add 10.6 to both sides

38.4 (+10.6) = 5x - 10.6 (+10.6)

5x = 49

Isolate the x, divide 5 from both sides

5x/5 = 49/5

x = 49/5

x = 9.8

9.8 should be your answer

hope this helps</span>

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget an
Sladkaya [172]

It will take 100 weeks to build the tower.

Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:

  • Time per block x total blocks = Total time
  • 1 week x 100 = X
  • 100 weeks = X

Therefore, it will take 100 weeks to build the tower.

In the expansion of (ax+1)^7<br> the fifth term is 945x^3<br> Find the value of a.
Advocard [28]

Answer:

a = 3

Step-by-step explanation:

First start writing out the binomial expansion of (ax + 1)^7

[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]

as you can see from this, the last bracket will produce our x^3 term

7C3*1^4*a^3x^3 \\35a^3x^3\\35a^3 = 945\\a^3 = 27\\a = 3

Hope this helps, let me know if you have any questions :)
