Answer:

  4. height: 5√3 cm; area: 25√3 cm²

  5. 30√2 ft ≈ 42.43 ft

Step-by-step explanation:

4. The height of an equilateral triangle is (√3)/2 times the side length, so is ...

  height = (√3)/2 × (10 cm) = 5√3 cm

The area is given by the formula ...

  A = 1/2bh

  A = 1/2(10 cm)(5√3 cm) = 25√3 cm²

__

5. The diagonal of a square is √2 times the side length, so the distance from 3rd to 1st base is ...

  (30 ft)√2 ≈ 42.43 ft

__

The length of the diagonal of a square is something you should be familiar with. If you're not, you can figure the distance using the Pythagorean theorem.

  d = √(30² +30²) = √1800 ≈ 42.43 . . . feet

Why isn't 10 a perfect square
nadya68 [22]
Because there is no number that when multiplied by itself that could equal to 10 (ex: 16 is a perfect square because 4 and 4 multiplied together equals 16; 4 and 4 are the same number)

Bruce's hourly wage increased from $12.00 to $13.00. What is the percent of increase?
vladimir1956 [14]

Answer:

Around 10

Step-by-step explanation:

Well, 10 percent of 12 is 1.2 because 12/10 is equal to that. Bruce's salary increased by exactly 1 dollar from 12 to 13. 1.2 can be rounded down pretty easily to 1 dollar so we know the answer is around 10. I don't really know everything about percentages so I'm not gonna take a wild guess and have you get it wrong. But not a lot of people are answering on brainly lately so I'm trying to help everyone as much as I can. Sorry, I hope this at least is a little bit of a guide for you.
