Answer:
true
Step-by-step explanation:
(2,-1) The intersecting point is the point where the two lines meet.
Answer:
29.42 units
Step-by-step explanation:
<u>1) Find the perimeter around the semi-circle</u>
To do this, we find the circumference of the circle using the given diameter:
where d is the diameter
Plug in 6 as the diameter

Divide the circumference by 2

Therefore, the perimeter around the semi-circle is 3π units.
<u>2) Find the perimeter around the rest of the shape</u>
Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those <em>vertical</em> sides facing the right add up to 6. We also know that all of those <em>horizontal </em>sides facing up add up to 7. Please refer to the attached images.
Therefore, we add the following:
7+6+7
= 20
Therefore, the perimeter around that area of the shape is 20 units.
<u>3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape</u>

Therefore, the perimeter of the shape is approximately 29.42 units.
I hope this helps!
We can find the number that is halfway between 6 and -10 by finding their average.
Number = (-10+6)/2 = -4/2 = -2
Therefore, the number halfway between them is -2.
The first thing we must do for this case is to find the scale factor based on the dimensions of the figures.
The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter than the next larger figure.
We have then that the smallest figure has a height of 1 inch.
The scale factor is:
k = (smallest figure) / (largest figure) = 1/7
k = 1/7
The surface area of the smaller figure is:
A = k ^ 2 * (A ')
Where
A ': surface area of the largest figure.
Substituting:
A = (1/7) ^ 2 * (588)
A = 12 in ^ 2
Answer:
The surface area of the smallest figure is:
A = 12 in ^ 2
