Answer:
r=7
Step-by-step explanation:
-84+15r=3r
Subtract 15r from each side
-84+15r-15r=3r-15r
-84 = -12r
Divide each side by -12
-84/-12 = -12r/-12
7 = r
Answer:
(25, 29)
Step-by-step explanation:
The midpoint formula can be solved to give an expression for one end point of a line segment in terms of the other end point and the midpoint.
<h3>Formula</h3>
The midpoint (M) of segment AB is found from ...
M = (A +B)/2
Solving for B, we get ...
B = 2M -A
<h3>Application</h3>
For A(-9, -1) and M(8, 14), we find the end point B to be ...
B = 2(8, 14) -(-9, -1)
B = (16 -(-9), 28 -(-1)) = (25, 29)
The other end point is (25, 29.
25 - 16 / 2^3 - 5 + 3
Start off by putting 2 to the third power to get 8. Then divide 16 by 8 to get 2. 25-2=23-5=18+3=21
Answer:
B
Step-by-step explanation:
If 2 chords of a circle intersect, then the product of the parts of one chord is equal to the product of the parts of the other chord , that is
BW × WD = AW × WC ( substitute values )
6 BW = 3 × 8 = 24 ( divide both sides by 6 )
BW = 4 units
Answer:
The necklace will be 4,000 cm long
Step-by-step explanation:
Here we want to calculate the length of the necklace
Mathematically, that would just be the product of the beads and the diameter of each bead
Hence, we have
10,000 * 0.4 = 4,000 cm
