robert is 12 years old
Step-by-step explanation:
robert's age=x
40=3x+4
that's the equation
40=3x+4
=36=3x
x=12
Answer:
Interval of 50 on both axis
Step-by-step explanation:
Given





There are several ways to do this, but I will use the observation method, since the dataset is small.
Considering the x-coordinates

Each element of the data set is a multiple of 50.
Hence, an interval of 50 can be used on the x-axis
Considering the y-coordinates

Each element of the data set is a multiple of 50.
Hence, an interval of 50 can be used on the y-axis
<em>So, an interval of 50 can be used on both axes</em>

Answer:
Estimate the value of pi =3.14
Step-by-step explanation:
The diameter of the circle base of a storage container 18.8m
The diameter of the circle 'd' = 2r
Given data 'd' = 2r = 18.8m
The circumference of the circle = 2πr
Given data of circumference of the circle = 59 m
given 2πr = 59
2r(π) = 59
18.8 π = 59 ( by using 2r =18.8)
π = 59/18.8
π = 3.13829
π = 3.14
<u>Conclusion</u>:-
Estimate the value of pi =3.14
