Answer:
C. 31 units
Step-by-step explanation:
Circumference of a circle is the distance around the circle and is given by C = pi•d
Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.
C = pi•10
= 3.14•10
= 31.4 using 3.14 as an approximation for pi.
Circumference is approximately 31 units.
Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 5 → (1)
y = 4x - 2 → (2)
Substitute y = 4x - 2 into (1)
4x - 2 = - 3x + 5 ( add 3x to both sides )
7x - 2 = 5 ( add 2 to both sides )
7x = 7 ( divide both sides by 7 )
x = 1
Substitute x = 1 into (2) for corresponding value of y
y = (4 × 1) - 2 = 4 - 2 = 2
Solution is (1, 2 )
Well the answer would be 120=120 and 68=68
Answer:
27
Step-by-step explanation:
To find the average change in elevation, you have to make it a unit rate. So we find that 378/14=27
