Answer:
The kids is 5.50 adult is 7..50
Step-by-step explanation:
we create an equation
2x + 3y =31.50
and
1x + 5y=35.00
1x is just x so we subtract 5y from both sides
x= 35.00-5y
fill x with 35.00-5y
2(35.00 - 5y) + 3y = 31.50
70.00 - 10y +3y = 31.50
-10y + 3y = -38.50
-7y=-38.50
-7y/-7= -38.50/-7
y=5.50
Answer:
the ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to 16 square feet.
Step-by-step explanation:
The actual area of the patio:
A = 20 feet long *16 feet wide = 320 square feet
The dimensions of the scale drawing are:
=> The scaled drawing area of the patio:
A = 5 in long * 4 in wide
= 20 square in
The ratio of the area of the scaled drawing to the actual area of the patio is:
the ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to 16 square feet.
b the perimeter of a square as a function of the side length
c the cost of gasoline as a function of the number of gallons purchased
d distance traveled by a car moving at constant speed as a function of time
The solution is Option A. The area of a circle as a function of the radius
The phrase which describes a non linear function is the area of a circle as a function of the radius
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
a)
The area of a circle as a function of the radius
So , the area of the circle A = πr² , where r is the radius of the circle
Now , the linear equations in one variable is an equation which is expressed in the form of ax + b = 0
So , the r² term in the area of circle does not make it a linear function
Hence , the non linear function is area of a circle as a function of the radius
