Answer:
D. 8.4* 10^8
Step-by-step explanation:
Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
1. Draw two arcs with the same radius at point A and B.
2. Join the intersection points C and D (see picture). The line CD bisects arc AB into two equal parts.
3. The point S of intersection of arc AB and line CD is a middlepoint of the arc AB.
Answer
(4x-5) = -20 (2x+8) = 2
Step-by-step explanation:
2 x − 8 = 2 2x-8=2 2x−8=2. Add 8 to both sides. Simplify 2 + 8 2+8 2+8 to 10. Divide both sides by 2. If its wrong then I’m very sorry but I’m sure this is correct.
Because the triangles are similar, their corresponding sides will have the same ratio. Side corresponding to PQ is AC and side corresponding to RC is PR. Thus:
RC/PR = AC/PQ
5.1 / 3.4 = 4.2 / PQ
PQ = 2.8 inches
