Step-by-step explanation:
angle MRP
angle PRS=angle RPN (alternate angles)
2x+x+x+78°=180°(sum of angles of a triangle)
4x+78°=180°
4x=180°-78°
4x=102°
4x/4=102°/4
x=25.5
= ( 3x² + 3x + 5 ) ( 6x + 4 )
= 18x³ + 18x² + 30x + 12x² + 12x + 20
= 18x³ + 30x² + 42x + 20
Answer:
About 3 times faster
Step-by-step explanation:
Cheetah's speed = 110 km / hr
World 100m sprint record :
Speed of sprinter :
Distance / time
100 m / 9.58s
= 10.438413 m/s
Convert Cheetah's speed to m/s
110 km/hr = (110 * 1000)m / (60 * 60 s)
= 110000 m / 3600 s
= 30.55555 m/s
Number of times cheetah is faster than sprinter :
30.55555 m/s ÷ 10.438413 m/s
= 2.927 times
Can u post a clearer pic? i can help u if u do :)
Answer:
5.5
Step-by-step explanation:
9 = x + 3.5
do 9 - 3.5 and get 5.5
