What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A ( t ) = 224 - 16t , where t is the number of trips
a)
The amount of money does Ahmad have left in the account after 11 trips on the toll roads be P
Substituting the value of t = 11 in the equation , we get
A ( 11 ) = 224 - 16 ( 11 )
A ( 11 ) = 224 - 176
A ( 11 ) = $ 48
So , The amount of money does Ahmad have left in the account after 11 trips on the toll roads is $ 48
b)
The number of trips on the toll roads can he take until his account is empty be n
when A ( t ) = 0
224 - 16t = 0
Adding 16t on both sides of the equation , we get
224 = 16t
Divide by 16 on both sides , we get
t = 14 trips
Hence , the equations are solved

The area of the triangle bounded by the x-axis, the y-axis, and the line y = −4x + 4 is 2 square units
How to find the area of the trianglegiven data
y = −4x + 4
Area of a triangle is equal to 1/2 * base * height
Assuming the y direction to be the height and the base is x direction
Point on the y direction is the y intercept since the line bounds the area
y intercept = −4( 0 ) + 4
y intercept = 0 + 4
y intercept = 4
Point on the x direction is the x intercept since the line bounds the area

The function f(x)= -200x+1000 represents the altitude (in feet) of a paraglider x minutes from the time the paraglider begins a descent to a landing site located 100 feet above sea level. Identify the slope, domain, and range.
Answers
The slope of the Function is -200, the domain of the function is any real value of x and the range of the function is [1000,∞).
The provided function is,
f(x) = -200x+1000
This function is representing the altitude of a paraglider and time from where the paraglider descent. Here, x is representing time in minutes.
The landing site is located at the depth of 1000 feet.
we can write the function as,
y = -200x + 1000
Here, y is the range of the function.
As we observes the function, it is an equation of line,
So, the slope is equal to the coefficient of x.
So the slope is -200.
The domain is any value of x for which the function is defined,
as this it an equation of line,
The domain would be any real value of x.
The range is the output that we get after putting value of x.
Here,
Put x = 0.
y = -200(0)+1000
y = 1000
Now. putting x = -1,
y = -200(-1) + 1000
y = 1200.
Putting any negative value of x will make y positive,
So, the range will be [1000,∞)

If you had half a dollar, three quarters, eight dimes, six nickels, and nine pennies, how much money would you have altogether?
Answers
If we have half a dollar, three quarters, eight dimes, six nickels, and nine pennies , then we altogether have $2.44 .
In the question ,
it is given that
we have half a dollar ,
which means half a dollar = $0.50
we have , three quarters means
we have 75 cents
and 75 cents = $0.75
we have 8 dimes ,
we know that 1 dime [tex]=[/tex] 10 cents
so , 8 dimes = 80 cents
and 80 cents = $0.80
we have six nickels,
we know that 20 nickels = $1
so , 1 nickel = $1/20
and 6 nickel = $ 6/20 = $0.30
we have nine pennies ,
we know that 100 pennies = $1
So ,1 Pennie = $1/100
and 9 pennies = $ 9/100 = $0.09
Combining all together we get
total money = half a dollar + three quarters + 8 dimes + six nickels + nine pennies .
Substituting the values , we get
total money = $0.50 + $0.75 + $0.80 + $0.30 + $0.09
