How tall is the tower?
Karo-lina-s [1.5K]

Answer:

  • 93.6 ft

Step-by-step explanation:

\bf \cfrac{AB}{BC}  =  \tan(60)

  • \bf \cfrac{x}{50}  =  \sqrt{50}
  • \bf x = 50 \sqrt{3}

Length of tower:-

  • \bf x + 7
  • \bf 50 \sqrt{3}  + 7
  • \bf 93.6025
  • \bf = 93.6

Therefore, the tower is 93.6ft tall.

Can 57 rows be divided into a number of equal sections? explain how you found your answer?
Helen [10]

You need to find out if 57 can be divided evenly by a number other than 1 and 57.

57 is odd, so it is not divisible by 2.

The digits of 57 are 5 and 7. Add 5 + 7 to get 12. Since 12 is divisible by 3 (12/3 = 4), then 57 is also divisible by 3.

57/3 = 19

19 is a prime number, so the only factors of 57 are 1, 3, 19, 57.

57 rows can be divided into 19 sections of 3 rows each or 3 sections of 19 rows each.

2. True/False: Adding a positive constant to each value in a quantitative data set does not affect measures of
zavuch27 [327]

Answer:

False

Step-by-step explanation:

When a constant is added to every data value in a data set?

If you add a constant to every value, the mean and median increase by the same constant. For example, suppose you have a set of scores with a mean equal to 5 and a median equal to 6. If you add 10 to every score, the new mean will be 5 + 10 = 15; and the new median will be 6 + 10 = 16.
