Answer:
1.38
Step-by-step explanation:
1.7-0.4=1.8
1.8/1.3=1.38
On graph place point at (1,8) and draw a triangle
Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.
Answer:
The value of radius is 34.395..
Step-by-step explanation:
The formula for finding the circumference of the circle is:
C=2πr.
Here we have given the values:
circumference = 216 units
π = 3.14.
r = ?
Substitute the values in the formula:
216 = 2(3.14)r
216=6.28r
Now divide both sides by 6.28.
We get,
216/6.28 = 6.28r/6.28
34.395=r
Thus the value of radius is 34.395...
Lateral area = 2πrh=2π(7)(32)=448π
end areas = 2πr² = 2π7²=98π
Total surface area=lateral area+end areas=(448+98)π=546π
