Answer:
For question 14
The answer is x= 52%
Step-by-step explanation:
Answer:
X equals 6°.
Step-by-step explanation:
There is a geometry rule that states the outer angle of a triangle's interior angle is equivalent to the sum of the remaining two interior angles of the triangle. Following this rule, you can get that (6x + 8) + (5x + 8) = 82° ⇒ 11x + 16 = 82° ⇒ 11x = 66° ⇒ x = 6°.
Answer:
postive 12
Step-by-step explanation:
16-4=12
Yes she does have enough. Here is why:
If you add 1/4 and 1/4, you get 2/8 which is also 1/2.
3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4.
So she would have 1/4 left.
Absolutely enough to get to her friends house and back. :)
Answer:
6
Step-by-step explanation:
We know that the area of a circle is equal to 
.
A semi-circle is a half-circle, meaning that it will have half of the area of a full circle.
Therefore, a semi-circle's area is equivalent to 
.
Set this equation equal to 18.
Solve for r.
We then find that r = 6.
Now, we need to find the circumference. We know that the equation for the circumference of a circle is 2r. Since we only need the perimeter of half of a circle, our circumference equation will equal r.
Plug 6 in for r.
The perimeter of the garden is equal to 6.
