Answer:
13 hearts, plus 3 other queens- so 16 out of 52, simplified 4 out of 13.
Answer:
x+y= 120
90x+250y=27,600
Step-by-step explanation:
x= number of certain tickets
y= number of remaining tickets
The statement indicates that for a particular flight the airline sold 120 tickets which means that the sum of the different tickets is 120. The first equation is:
x+y= 120
Then, the statement says that certain number of tickets costs $90 and the remaining tickets cost $250 and that for a particular flight, the airline collected $27,600. From this, you can say that the number of certain tickets, x, multiply for its price that is $90 plus the number of the remaining tickets, y, multiply for its price that is $250 would be equal to $27,600. The equation would be:
90x+250y=27,600
According to this, the answer is that the system of equations that represents this relationship between x and y is:
x+y= 120
90x+250y=27,600
Answer:
$2942.27
Step-by-step explanation:
Given the circumference of a circle, we can get the radius which will then help us get the area and finally estimate the cost of tiling.
C=2πr
Where C is circumference and r is radius
Making r the subject of the formula then
r=C/2π
Substituting 157 ft for C then
r=157/2π=24.9873260654276 ft
Area, A is given by A=πr²
A=π*(24.9873260654276)²=1961.50509613606
Rounded off, the area is 1961.51 ft²
Given the cost per unit square foot as $1.5 then the overall cost will be
$1.5*1961.51=$2,942.265
Rounded off as $2942.27
