Answer:
56.52
Step-by-step explanation:
C = 2 x pi x r
r = 9
C = 2 x pi x r
multiply 2 by 9
C = 18 x pi
C = 56. 52
X=5/2
4x7.5=12x
30=12x
X=30/12
X=5/2
Answer:
that one bus cost 5$
Step-by-step explanation:
each van is .25 so multiply it by 2 and its .50
so if there are 3 buses each bus cost 5 cause 5 x 3 = 15
adding the vans will make a total cost of 15.50
Answer:
0.8
Step-by-step explanation:
to find the decimal equivalent we must get the denominator to 100
to do that we must multiply it by 20, 4/5 * 20/20 is 80/100
80/100 is also 80%, which is also 0.80 (which can be simplified to 0.8)
f(-2)=g(-2)
Think of the number in parentheses as your x value. f(x)=y. In this case the line hit at (-2,4) so when f(x) = 4, g(x)= 4 and 4=4 so you then have to find the x which in this case is -2. I’m pretty bad at explaining but there’s your answer
