Is the sum of 3√2 and 4 √2 rational or irrational? Explain your answer.
Sum of 3√2 and 4√2 is an irrational number.
What are irrational numbers?" Irrational numbers are those numbers which cannot be written in fraction or rational form."
According to the question,
Suppose 3√2 + 4√2 be a rational number.
which can be expressed in form of (p / q) form such that 'q' does not divides 'p'
3√2 + 4√2 = (p / q)
⇒ 7√2 = ( p / q)
Squaring both the sides we get,
49 × 2 = ( p² / q² )
⇒ 2 ×(49q²) = p²
⇒ p is an even number
⇒p = 2k , k≠0
Therefore,
2 × ( 49q²) = (2k)²
⇒2×(49q²) = 4k²
⇒q² = (2k² / 49)
Both p and q are even which implies 'q' divides 'p'.
It is contradictory to our supposition,
Therefore, 3√2 + 4√2 is an irrational number.

ricardo's recipe for 4 loaves of bread requires 2/3 cup of olive oil. He only wants to make 1 loaf. Ricardo makes a model to find out how much oil he needs to use. He folds a piece of paper into three parts and shades two parts. Then he folds the paper into four parts and shades 1/4 of the shaded part. Ricardo decides he needs 1/4 cup of olive oil. Is he right? Explain
Answer:
Ricardo is wrong.
Step-by-step explanation:
Ricardo's recipe for 4 loaves of bread requires 2/3 cup of olive oil.
Now we are given that he wants to make 1 loaf.
So, 4 loaves requires cup of oil = [tex]\frac{2}{3}[/tex]
So, 1 loaf requires cup of oil = [tex]\frac{\frac{2}{3}}{4}[/tex]
= [tex]\frac{2}{12}[/tex]
= [tex]\frac{1}{6}[/tex]
Thus he requires 1/6 cup of oil to make 1 loaf .
While he decided he needs 1/4 cups .
So, Ricardo is wrong

Noah bought 1/2 pound of candy to share with his friends.They ate 3/8 pound of the candy.How much candy does Noah have left?
Total pound of candy with Noah = [tex] \frac{1}{2} [/tex]
Total pound of candy eaten by his friends = [tex] \frac{3}{8} [/tex] of [tex] \frac{1}{2} [/tex]

Emma created the poster shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 24 cm. What would be the dimensions of the poster at fraction 1 over 4 times its current size? Length = 32 cm, width = 20 cm Length = 40 cm, width = 28 cm Length = 144 cm, width = 96 cm Length = 9 cm, width = 6 cm
Answer:
Length = 9 cm, width = 6 cm
Step-by-step explanation:
If the length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 24 cm.
Length = 36cm
Width = 24cm
One fourth the current size of the rectangle will be;
New length= 1/4×36 = 9cm
New width = 1/4 × 24 = 6cm
The new dimension of the poster is therefore 9cm×6cm
Length = 9cm
Width = 6cm

One number is bigger than another by 406. If the bigger number is divided by the smaller one, you’ll get the quotient 3 and remainder 66. Find the numbers.
To find the numbers, we can set up a system of equations and solve it using substitution.
Explanation:To find the numbers, we can set up a system of equations based on the given information. Let's call the bigger number 'x' and the smaller number 'y'. We know that x is bigger than y by 406, so we can write the equation x = y + 406. We also know that when x is divided by y, the quotient is 3 and the remainder is 66. This can be expressed as the equation x = 3y + 66.
We can solve this system of equations by substitution. First, we substitute the expression for x from the first equation into the second equation:
3y + 66 = y + 406
Next, we can subtract y from both sides of the equation:
2y + 66 = 406
Then, we subtract 66 from both sides:
2y = 340
Finally, we divide both sides by 2 to solve for y:
y = 170
Now we can substitute the value of y back into the first equation to find x:
x = 170 + 406 = 576
Therefore, the numbers are 576 and 170.
