Answer:

25 degrees

Step-by-step explanation:

By the Law of Sines,

(sin R)/20 = (sin(50°))/(36)

sin R = (20sin(50°))/36

R = arcsin((20sin(50°))/36), which is about 25 degrees.

Pablo spit 3/4 pounds of candy amping 4 people what is the unit rate in pounds per person
Sunny_sXe [5.5K]

The unit rate is \frac{3}{16} pounds per person.

Given,

Quantity of candy Pablo have = \frac{3}{4} pounds

Number of people = 4

We will divide the Quantity of candy by number of people.

Quantity of candy per person = \frac{3}{4}*\frac{1}{4}

Quantity of candy per person = \frac{3}{16} pounds of candy

The unit rate is \frac{3}{16} pounds per person.

Find the weight of the cast iron shape shown below at 0.26 pounds per cubic inch. (round to the nearest pound). The height of th
weqwewe [10]

Answer:

<u>640 pounds </u>

Step-by-step explanation:

The rest of the question is the attached figure

So, the total volume = V(cylinder ) + V(cone)

The volume of cylinder = π r² h

The volume of cone = π r² h/3

Both of the cylinder and the cone have the same diameter = 14 inches

So, the radius = 14/2 = 7 inches

The height of the cylinder is 13 inches and the height of the cone is 9 inches.

So, The volume of cylinder = π r² h = π * 7² * 13 = 2,001.2 in³

And The volume of cone = π r² h/3 = π * 7² * 9/3 = 461.8 in³

So, the total volume = 2,001.2 + 461.8 = 2,463 in³

So, the total weight = 0.26 pounds per cubic inch times the total volume

                                = 0.26 * 2463 = 640.38 pounds

                                = <u>640 pounds (to the nearest pound)</u>
