He changed the table style
Step-by-step explanation:
Just did the assignment :)
Semicircle perimiter=1/2circumferece+diameteter
diameter=2r
c=2pir
so 1/2circumference=1/2(2pir)=pir
d/2=r
given
d=30
d/2=30/2=15=r
perimiter=pir+d
perimiter=15pi+30
aprox
perimiter=77.1239
total cost=cost per foot times feet
total cost=9.25 times 77.1239
total cost=713.396
it will cost $713.40
Answer:
a=45 b=65
Step-by-step explanation:
You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above
Move all terms not containing a to the right side of the equation.
a=129/64
I hope this helps :)
Answer:
The common difference between numbers is 7.
3
3+7=10
10+7 = 17
17+7=24
24+7=31
31+7= 38
3, 10, 17, 24, 31, 38
