Step-by-step explanation:
XP=4
PT=1
XT=4+1=5
Shaded area=π(5²-4²)=π(25-16)=9π≈9×3.14=28.26 square units
Answer:
x=81 degrees z=99 degrees y=68 degrees
Step-by-step explanation:
first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180) so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
Answer:
Speeds of car 1 and car 4 are same.
Step-by-step explanation:
Speed of an object =
For car 1,
Speed of car 1 =
= 70 miles per hour
For car 2,
Speed of car 2 =
= 60 miles per hour
For car 3,
Speed of car 3 =
= 64 miles per hour
For car 4,
Speed of car 4 =
= 70 miles per hour
Therefore, speeds of car 1 and car 4 are same.
Answer:
-3
Step-by-step explanation:
slope = Δy / Δx = -6/2 = -3
Solve your equation step-by-step.
7x2+2x=0
Factor left side of equation.
x(7x+2)=0
Set factors equal to 0.
x=0 or 7x+2=0
x=0
or
x=−2/7
