brain's mother ordered a pizza thar had 12 slices for dinner. Brian ate 1/3 of the pizza,and his mother ate 1/6 of the pizza .how many slices were left?

Answers

first we have to figure out how many slices each of them ate

brian ate 1/3 of 12 which is 4
mother ate 1/6 of 12 which is 2

together they both ate 6

12-6 is 6

there were 6 slices left

Only 6 slices were left of the Pizza. Put 12 slices into a ratio 12/12. 1/3 x 4 is 4/12 so thats 4 slices brian Ate and 1/6 x 2 is 2/12 so thats 2 slices his mother ate. 2+4=6 Slices of pizza. 12-6 = 6 remaining pieces of pizza.

"when you adjust one number and change another number in the problem to make a computation easier, you use ........... "

Answers

The compensation strategy is used in mathematics when taking the sum of two or more values in other to make computation easier.

Compensation involves adjusting the value of a certain number before processing with addition in other to make the calculation easier.

For example ; 29 + 33
We could change the value of 29 to 30 by adding 1 ; as it is easier to sum 30 and 33.
Then ; 30 + 33 = 63
The added value is then subtracted from the result.
63 - 1 = 62
Hence, 29 + 33 = 62

The above example is a simple way of using the compensation strategy.

What is Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagoreantheorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Let the length of the rope be x.

Now, x²=53²+28²

⇒x²=2,809+784

⇒x=59.94≈60

Therefore, the length of the rope is 60 feet.

So Pythagorean theorem, I assume.
remember: $a^(2) + b^(2) = c^(2)$
The a and b seems to be 53 and 28 (the order doesn't really matter)
so, $53^(2) + 28^(2) = c^(2)$
OR $\sqrt{53^(2) + 28^(2) } = c$

Calculator time!
$√(2809 + 784)$
$√(3593) = c$
59.94 ≈ c
Therefore, the rope is approximately 59.94 feet long.
