Answer:
Step-by-step explanation:
Formula (Normal Area Trapezoid)
A = (b1 + b2 ) * h / 2
Formula (Trapezoid Modified for the question)
b1 + b2 is given as 90
Area = 90*h / 2
Givens
b1 + b2 = 90
Area = 1170
h = ?
Solution
Area = 90 * h / 2 Substitute the givens into the formula
1170 = 90 * h/ 2 Divide by 2 on the right.
1170 = 45 * h Divide both sides by 45
1170 / 45 = 45 * h/45

<em>Answer: h = 45 inches.</em>
Answer:
$1068.95
Step-by-step explanation:
Gross Pay = $1200
Health Insurance deducted = $42.50
Taxable Pay = 1200 - 42.50
= $1157.50
Social security rate = 6.2%
= 
= 0.062 (converted into decimal)
Social security Tax = Taxable Pay * Social security rate
= 1157.50 *0.062
= 71.765
= $71.77 (rounded off to the nearest hundredth)
Medicare Tax rate = 1.45%
= 
= 0.0145 (converted into decimal)
Medicare Tax = Taxable Pay * Medicare Tax rate
= 1157.50 * 0.0145
= $16.78
Net Pay = Gross Pay - Health Insurance deducted - Social security Tax - Medicare Tax
= 1200 - 42.50 - 71.77 - 16.78
= 1200 - (42.50 + 71.77 + 16.78)
= 1200 - 131.05
= $1068.95
Answer:
Equation of the circle =
80 = ( x - 1)^2 + (y + 1)^2
Step-by-step explanation:
Center = (1 , -1)
Point = ( 5 , 7)
Eqn of a circle is
r^2 = (x - h)^2 + (y - k)^2
We are not given the radius of the circle, fortunately we are provided the information that the circle contains a point ( 5, 7), so we use the above information to find r
Using the center (1, -1)
h - 1
k - -1
r^2 = (x - 1)^2 + ( y - -1)^2
r^2 = (x - 1)^2 + (y + 1)^2
With the point ( 5,7)
x = 5
y = 7
r^2 = ( 5 - 1)^2 + ( 7 + 1)^2
= 4^2 + 8^2
= 16 + 64
= 80
r^2 = 80
r = square root of 80
r = 8.94
The r = 8.94 , which means the equation of the circle is
80 = (x - 1)^2 + ( y + 1)^2
Answer:
800 g would cost $12.98
since 800 g is double 400 g just multiply 6.49 by 2.
42 cm because if you divide 210 and 1260 it will make 6 so u just multiply it by 7 and u get 42
