Answer:
41
Step-by-step explanation:
First, we need to find the sum of the ages of the first five people.
20 + 15 + 25 + 17 + 20 = 97
Then, multiply 23 by 6 to get the sum of the ages of all six people.
23 x 6 = 138
We then subtract 97 from 138 to get the age of the sixth person.
138 - 97 = 41
Answer:
36 degrees
Step-by-step explanation:
Ok so wouldnt you have to subtract 54 minus 18? and if so then
First you want to set this into a fraction, so it would be 18/1 because every number has an imaginery one underneath it. then when you divide a fraction you multiply by the reciprical(the opposite) so it would be 18/1 times 3/1 then you can simply cross mutiply and divide, which you can't so then you simply take 18 times 3 which is 108/1 then you divide 108 divided by 1 which is 108, your answer is 108
Answer:
Minimum 66 feet of molding that he needs.
Step-by-step explanation:
Given that a square ceiling has a diagonal of 23 ft.
If the sides of the square ceiling are 'a' feet, then applying Pythagoras Theorem we can write, a² + a² = 23²
⇒ 2a² = 23²
⇒ a = 16.2634 feet (Approximate)
Now, the perimeter of the square ceiling will be 4a = 65.05 feet.
If the cost of molding along the perimeter of the ceiling is in per foot, then a minimum of 66 feet of molding that he needs. (Answer)
