A solid has 16 faces and 14 vertices. How many edges does the solid have? A. 14 edges B. 18 edges C. 20 edges D. 28 edges

1 answer:

7 0

The formula to use is F +V -E = 2

F = Faces = 16
V = Vertices = 14
E = edges = Unknown

We can fill in the information we have and solve for edges:

16 + 14 - E = 2

Add 16 and 14:

30 - E = 2

E = 30-2

E = 28

There are 28 edges

Solve the following inequality for d. Write your answer in simplest form.

suter [353]

Answer:

d>67

Step-by-step explanation:

Let's solve your inequality step-by-step.

−50−(−9d+7)>−d+10+9d

Step 1: Simplify both sides of the inequality.

9d−57>8d+10

Step 2: Subtract 8d from both sides.

9d−57−8d>8d+10−8d

d−57>10

Step 3: Add 57 to both sides.

d−57+57>10+57

d>67

The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Substitute the given parameters

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm
