1/2*-3 1/2 = -21/4 = -5 1/4= <em>-5.25</em>
I hope this helps!!
Answer:
B. 12:240
Step-by-step explanation:
- 9:180
⇒ 1:20
Optiona (A) 5 : 200 it is not multiple of 1:20, Eliminate.
Option (B) 12:240, it is multiple of 1:20 ( x 12) , quality
Option (C) 10:400 , Eliminate
Option (D) 8:560 , Eliminate
Hence, 12:240 is equivalent to 9:180.
Answer:
First one
Step-by-step explanation:
First one, because one x-value can't have two y-values.
A function always outputs one y-value. But it can have two x-values for one y-value.
Hope this cleared things up for you!
(D) because dividing 624 by 4 gives you the answer.
1) find the are of the circle: πr²
2) find the area of each triangle: (base x altitude)/2
3) subtract the triangles from the circle are
1) area of circle:π.5² = 25 π
2) Area of the triangle = (6 x 4)/2 =12 cm². We also notice that both triangles are congruent SSS (6,5 & 5), so the total surface of the 2 triangles = 24 cm²
3) (25π - 24) cm² is the answer
