Answer:

Number 4: Using Pythagoras Theorem,

$\sqrt{30^2+40^2} =50$

Number 5:

$\sqrt{41^2-40^2}=9$

$\sqrt{11^2+60^2} =61$ It is a right triangle

$\sqrt{9^2+37^2} =38.09$ Not a right triangle

For the last one:

$\sqrt{(\sqrt{20^2+6^2})^2+6^2} =2\sqrt{118}$

Rounded down (because the answer needs to be a whole number) is 21

You have 23 1/2 pounds of blueberries to store in freezer bags. Each bag holds 3 3/4 pounds of blueberries. What is the minimum

monitta

Answer:

The minimum number of freezer bags needed to store all the blueberries is 7

Step-by-step explanation:

we know that

To find out the number of freezer bags needed , divide the total pounds of blueberries by 3 3/4, but first convert mixed number to an improper fraction

$23\frac{1}{2}\ lb=\frac{23*2+1}{2}=\frac{47}{2}\ lb$

$3\frac{3}{4}\ lb=\frac{3*4+3}{4}=\frac{15}{4}\ lb$

$\frac{47}{2}:\frac{15}{4}=\frac{47*4}{2*15} =\frac{94}{15}=6.3\ bags$

Round up

7 bags

therefore

The minimum number of freezer bags needed to store all the blueberries is 7
