Answer 1

Answer:

Answer:

27 degrees

Step-by-step explanation:

1= 63 degrees

Using alternating angles, acute angle made at T is 63 degrees.

Angles in a triangle add upto 180, thus, 90+ 63= 153

180-153 = 27

What is the answer to this problem and why 60+60×0+1=

Answers

The answer is 61 because 60+60=120*0=0=1=61

60 + 60 x 0 + 1 = 61

Let's go into the, "why" part!

Try to remember this mnemonic:
PEMDAS

Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction

This is what is called the ORDER of OPERATIONS!

Normally you go straight down the list, but...
Keep in mind that Multiplication and Division are on the same priority. Same with Addition and Subtraction.

So first we look to see if there is any numbers in parenthesis. There is not. Any exponents? Nope!
How about Multiplication or Division?
Yep!!!!! Bingo!

60 + 60 x 0 + 1= ?

Do the multiplication first. 60 x 0 = 0 (Because anything times 0 equals 0)

Addition and subtraction come next!

60 and 0 are out so we are left with!

60 + 1 = ?

61!

Step-by-step explanation:

The following are the ages (years) of 5 people in a room: 25, 18, 17, 13, 24 A person enters the room. The mean age of the 6 people is now 22. What is the age of the person who entered the room?

Answers

Answer:

See Below:

Step-by-step explanation:

Average is take by adding all the terms together and dividing by the number of terms. In this case it terms is people in the room.

22= (25+18+17+13+24+x)/6

Where 22 is the average age. The numerator is all the known ages added together, plus x which is the age of the person who just entered. Divided by 6 because you are finding the average age of 6 people.

22 = (25+18+17+13+24+x)/6 Multiply both sides by 6

132= 97+ x Subtract 97 from both sides.

35 = x

The person who just entered the room is 35 years old.

Final answer:

To solve this, we first find the total age of the original five people, then the total age of all six with the given mean age. By subtracting these, we find that the age of the person who entered is 35 years old.

Explanation:

This problem can be solved using simple arithmetic. First, we calculate the total age of the first 5 people, which is 25 + 18 + 17 + 13 + 24 = 97 years. Then, we need to determine the total age of all 6 people. We're told the mean (average) age of these 6 people is 22. We find the total by multiplying the mean by the number of people, so 22 * 6 = 132 years. Finally, to find the age of the person who entered the room, we subtract the total age of the first 5 people from this new total, i.e. 132 - 97 = 35 years. So, the person who entered the room is 35 years old.
