Answer:
700
Step-by-step explanation:
For this one I'll do estimates. 271 estimated would drop down to 270. And 425 would bump up to 430. Adding 270 and 400 you would get a round number of 700!
Hope this helped.
Answer:
The distance from point A to the top of the building is 5
feet
The Height of the Skyscraper is 5 feet
Step-by-step explanation:
Given
Let Top point of building be point C
Also Let Base of the building be point B
Distance from point A to base B of the building AB= 5 feet
∴ It makes a Right angle triangle
Also ∠ACB = 45°
Also tan 45° = 1
Now tan ∠ACB =
∴ AB= BC =5 feet
The Height of the Skyscraper is 5 feet
Now Triangle ABC is right angle triangle with right angled at B
So by Pythagoras theorem
AC= 
The distance from point A to the top of the building is 5 feet
A= a+b/2h =10+20/2 x13 =195
I believe 195 is correct if not, I’m so sorry
Answer:
550.2cm
Step-by-step explanation:
6 cm x 7 cm x 13.1 cm = 550.2 cm
6.37² x 3.1
First is Exponents (6.37²):
40.6 x 3.1
Then, Multiplication:
40.6 x 3.1 = 125.9.
To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.
Example:
(5-2)5 + 2² / 6 -1 = ?
First, Parentheses:
(3)5 + 2² / 6 - 1
Then, Exponents:
(3)5 + 4 / 6 - 1
Then, Multiplication:
15 + 4 / 6 - 1
Then, Division:
15 + 0.7 - 1
Then, Addition:
15.7 - 1
Then, Subtraction:
14.7
So that means, (5-2)5 + 2² / 6 -1 = 14.7
