Answer:
20 ; $135 ; service charge for 3 hours spent is $135
Step-by-step explanation:
Given that :
Service fee equation model :
C(h)= 75 + 20h
C = total cost of the service call
h = number of hours the plumber spends working on the problem
The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours
bx = 20h
b = 20
Charge per hour = 20
C(3) = 75 + 20(3)
75 + 60 = 135
This means that total service call charge for a plumber who spends three hours fixing a problem is $135
We gots triangle and half circle
square is meaning all sides are 20
that means height and base are 20 (isocelese)
and diameter is 20
area triangle=1/2bh=1/2(20)(20)=200
square=side*side=20*20=400
semicircle=1/2*pir^2
d/2=r, 20/2=r=10
semi=1/2*pi*10^2=1/2*pi*100=50*pi
using aprox pi=3.141592
semi=157
add them all
200+400+157=757
G is answer
Let x = state b , then x + 2 = state a
now: x + (x +2) = 9090 or 2x + 2 = 9090 Solving this equation:
2x + 2 = 9090 subtract 2 from both sides
2x = 9088 divide both sides by 2
x = 4544
that means x + 2 = 4546
so state a = 4546 and state b = 4544
X+2y=10
6x+6y=6 -> x+y=1
(x+2y=10)-(x+y=1)=y=9
x+(2*9)=10
x+18=10
x=-8 and y=9 -> c
