Chef Jordan has modes for chocolate, modeled by the cylinder below. He has a rectangular block of chocolate that measures 10 cm by 12 cm by 18 cm. He melts the block of chocolate and uses it to fill the molds. How many molds can he fill completely with the melted chocolate? Use 3.14 for . Round all answers to the nearest whole number.

He can fill 76 molds

Step-by-step explanation:

First find the volume of the rectangular block.

V = b(h)(w)

V = 10cm(12cm)(18cm)

V = 2160cm³

Now find the volume of the cylinder mold

V = πr²(h)

V = π1.5cm²(6cm)

V = 4.71cm²(6cm)

V = 28.26cm³

Now divide the volume of the rectangular block by the volume to find the number of cylinders needed.  

2160cm³/28.26cm³ = 76.43 cylinders. Rounded = 76

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
