Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15

The critical path of a project includes 45 business days in phase one, 20 business days in phase two, 15 business days in phase
tester [92]

Using proportions, it is found that the deadline for the project is of April 17th.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of days they need is:

45 + 20 + 15 + 10 = 90.

The number of weeks they need, considering 6-day weeks, is:

90/6 = 15.

Looking at a calendar, we have that:

  • 4 weeks after January 2nd is January 30th.
  • 8 weeks after January 2nd is February 27th.
  • 12 weeks after January 2nd is March 27th.
  • 13 weeks after January 2nd is April 3rd.
  • 15 weeks after January 2nd is April 17th.

The deadline for the project is of April 17th.

Use the formula A=P(1+r/n) to the n times t power

P= initial investment 500
r= Rate 8% change to decimal .08
n= number of times compounded which is quarterly so 4
t= time which is just 1 for one year

PLEASE HELP 20 POINTS!
Blizzard [7]

Answer:

Option D

Step-by-step explanation:

According to the image description provided:

Term one starts with one dot. One is an odd number.

If you add two to an odd number, the sum would be another odd number. This is what's happening with the pattern.

For example:

3+2 =5

Three is an odd number. If you add two to it, you would get five, which is another odd number.

Term two has 3 dots, term three has 5 dots, term four has 7 dots.

So, all terms should be odd.

Option D should be the correct answer.
