The answer is 0.0055 rounded
$8.16 is the unit rate per hour so just multiply the amount she makes per hour by hours. so there were 8 whole hours. $8.16*8=$65.28. then you have half an hour so $8.16/2=4.08. add. ANSWER: $69.36
Answer:
The circumference and the area of the circle are 6.28 yards and 3.14 yd² respectively.
Step-by-step explanation:
Circumference: This is defined as the distance around a circle.
The circumference of a circle is
P = πd............................. Equation 1
Where p = circumference of the circle, d = diameter of the circle
Area: This is the region bounded by a plane surface.
The area of a circle is
A = πd²/4 .................................. Equation 2
Where A = area of the circle, π = pie = constant.
Given: d = 2 yd.
Constant: π = 3.14
Substituting these values into equation 1 and 2 respectively.
P = 3.14(2)
P = 6.28 yard.
P = 6.28 yd
and
A = 3.14(2)²/4
A = 3.14×4/4
A = 3.14 yd²
Thus the circumference and the area of the circle are 6.28 yards and 3.14 yd² respectively.
Answer:
x = -6
Step-by-step explanation:
y = -x equation 1
x + 6y = 30 equation 2
using equation 1 in equation 2 we have:
x + 6(-x) = 30
x - 6x =30
-5x = 30
x= -30/5
x= -6
angles a and b are supplementary because they form a straight line
