3/2y-3+5/3 when y=6 and z=3
marissa [1.9K]

Answer:

5 \frac{1}{3}

Step-by-step explanation:

Assuming We want to evaluate

\frac{3}{2y - 3} +  \frac{5}{3} z

When y=6 and z=3.

We substitute to get:

\frac{3}{2 \times 6 - 3} +  \frac{5}{3}  \times 3

We multiply to get:

\frac{3}{12 - 3} +  \frac{15}{3}

We simplify the denominator to get:

\frac{3}{9} +  \frac{15}{3}

Reduce the first fraction:

\frac{1}{3} +  \frac{15}{3}

Add the numerator and keep one denominator for they are like fractions

\frac{16}{3}

Write as a mixed number:

5 \frac{1}{3}

a maxicool consists of a cone full of ice cream with a hemisphere of ice cream on top. the radius of a hemisphere is 3cm. The he
Gemiola [76]

According to the information, it can be inferred that the volume of the ice cream is close to 207.33 cm³

<h3>How to calculate the volume of the maxicool?</h3>

To calculate the volume of the maxicool, we must calculate the volume of the sphere of ice cream, and the volume of the cone that is filled with ice cream.

<h3>Volumen of the sphere</h3>

V = \frac{4}{3} × π × R³

V = \frac{4}{3} × π × 3³

V = 113.09 cm³

<h3>Cone volume</h3>

V = \frac{1}{3} × π × R² × <em>h</em>

V = \frac{1}{3} × π × 3² × 10

V= 94.24 cm³

Finally we must add both values to know the total volume of the maxicool.

113.09 + 94.24 = 207.33 cm³
