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

So here, ABCD is being inscribed in a circle, so ABCD is a cyclic quadrilateral (as inscribed in a circle) also, there exists a property of cyclic quadrilateral, i.e, the sum of opposite angles of a cyclic quadrilateral is 180°, so we can just write the following equation using this :

${:\implies \quad \sf y^{\circ}+83^{\circ}=180^{\circ}}$

${:\implies \quad \sf y^{\circ}=180^{\circ}-83^{\circ}}$

${:\implies \quad \sf y^{\circ}=97^{\circ}}$

${:\implies \quad \boxed{\bf{y=97}}}$
