Find the Area of the figure below, composed of a rectangle and a semicircle.
Mamont248 [21]

Answer:

68.1 units²

Step-by-step explanation:

Start by finding the area of the rectangle...

Area=lw\\Area=6*9\\Area=54

Then, find the area of the semicircle...

Radius=\frac{1}{2}*Diameter=\frac{1}{2}*6=3

Area=\frac{1}{2}\pi r^2\\Area=\frac{1}{2}\pi 3^2\\Area=\frac{1}{2}\pi 9\\Area=\frac{9}{2}\ pi\\Area\approx14.1

Now, add the two to get...

54+14.1=68.1

Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) 9^{2} + 12^{2} = 225

As a salesperson, you are paid $100 per week plus $3 per sale. This week you want your pay to be at least $160. Write an inequal
Rom4ik [11]

Answer:

100 +3s≥ 160

You must sell as least 20 items

Step-by-step explanation:

You make 100 plus 3 dollars per sale

100 +3s

It must be at least 160

100 +3s≥ 160

Now we need to solve to see how many sales

100 +3s≥ 160

Subtract 100 from each side

100-100 +3s≥ 160-100

3s≥ 60

Divide each side by 3

3s/3≥60/3

s≥20

You must sell as least 20 items

Change word phrase to expressions or equations<br><br> The sum of p and 45 less than 89
stellarik [79]

Answer:

p + 45 < 89

Step-by-step explanation:

The sum of something is the result of addition so you know that they are adding p and 45 together. They then state that p plus 45 must be less than 89. You can show that by using the less than symbol "<"

If you want to find all of the different values that P could equal then all you have to do is subtract 45 from both sides so the equation would be

p < 44

this means that p can equal anything less than 44 for this statement to be valid. Hope this helped!
