Answer:
Hence the simplification of is
Step-by-step explanation:
" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter),
for example: Simplification of a fraction to an irreducible fraction ".
Here we are given a fraction as:
As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.
As 66=3×22 and 81=3×27
Hence
Hence the simplification of is
Answer:
9 and 3.35 respectively
Step-by-step explanation:
Mean=Sum of data÷No. of data
=(3+5+6+9+11+12+17)÷7
=63÷7
=9
Standard Deviation=√{(sum of squares of data÷no. of data)-(sum of data÷no. of data)
=√(705÷7)-(63÷7)
=√100.71÷9
=√11.19
=3.35
divide 18 cups if flour into two groups so the ratio is 4 to 5
2 teaspoons
21+21=42 so for every 1 teaspoon there is 42 people
42+42=84 so it’s 2 teaspoons
Answer:
Let's imagine that x is the number of teaspoon of salt needed to make at least 84 cupcakes.
So we know that, 1 batch makes 21 cupcakes, and we need at least 84 cupcakes, so the number of cupcakes batch needed here should be:
84 ÷ 21 = 4 (batches)
Since we knew the number of batches that we need to make the cupcakes, we now calculate the amount of sugar needed. We have:
1/2 teaspoon of salt for every 1 batch.
x teaspoon of salt for every 4 batches.
x = (4 . 1/2) . 1 = 2 (teaspoons)
