Answer: 54 ft²
Step-by-step explanation:
Area of a kite is calculated by the formula:
= (Length * Height) / 2
Length = 6 + 6 = 12 ft
Height = 9 ft
Area = (12 * 9) / 2
= 108 / 2
= 54 ft²
A: the independent variable is the number of soccer games you officiate
B: the dependent variable is your earnings
C: e = earnings; s = soccer games
e = 15s
Answer:
187.06 units²
Step-by-step explanation:
Area of kite:
½ × d1 × d2
½d1 = 18sin(30)
½d1 = 9
d1 = 18
d2 = 9/tan(60) + 18cos(30)
= 12sqrt(3)
Area = ½ × 18 × 12sqrt(3)
108sqrt(3) units²
187.0614872 units²
Answer:
$38.31
Step-by-step explanation:
Given:
Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.
Question asked:
How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?
Solution:
At cost $24.35/ounce, pure silver is mixed = $33.48
At cost $1/ounce, pure silver is mixed = 
At cost $27.87/ounce, pure silver is mixed = 

Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.
The values of (x, y) are (-5, 1), if the equations
and
are solved by elimination method.
Step-by-step explanation:
The given is,
................................(1)
.....................................(2)
Step:1
Equation (2) is multiplied by -1 ( Eqn (2) × -1 )
..................................(3)
Step:2
Substrate the equation (1) and equation (3),


( - )
After the Subtraction equation becomes,




Step:3
By using y value find value of x,




Step:4
Check for solution,



Both sides are equal so answer is corrected
Result:
The values of (x, y) are (-5, 1), if the equations
and
are solved by elimination method.
