Carmen has 1.50$ in a coffee can She is going to place a quarter in the can every day for x days. If she does not remove any of the money, which expression below represents the total amount of money, indollars, that she will have in the can after x days?
Answers
The correct representation for the total amount of money in dollars will be;
⇒ $1.50 + $0.35x
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:
Carmen has 1.50$ in a coffee can.
She is going to place a quarter in the can every day for x days.
Now,
Carmen has 1.50$ in a coffee can.
And, She is going to place a quarter in the can every day.
That mean;
Cost = $1.50 / 4 = $0.35
And, For x days, the cost = $0.35x
Hence, Total amount = $1.50 + $0.35x
Thus, The correct representation for the total amount of money in dollars will be;
⇒ $1.50 + $0.35x

The length of longer side of the rectangular flower bed is 7.5m .
Given, that sketch dimensions of the rectangular flower are 4 cm by 6 cm.
Conversion of meter to centimeter.
1m ⇒ 100cm
So, 100 x 5 = 500cm
Now the shorter side of the flower corresponds to 4cm.
In actual the value in centimeters,
500 ÷ 4 = 125
Length of longer side of the rectangle.
125 x 6 = 750 cm
Convert cm to m.
1cm ⇒ 0.01 m
750/100 = 7.5 m
Therefore the length of longer side of rectangle is 7.5 m

The polar form of the equation x² + y² = 16 is x = 4 or y = 4 or r = 4 ( x = y = r = 4) option (B) is correct.
What is the polar equation?
A polar coordinate system is a two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane.
It is given that:
The rectangular form of an equation is:
x² + y² = 16
The above equation representing a circle equation:
We can write the above equation as follows:
x² + y² = 4²
As we know, the polar form of the equation is:
x = r cos(θ)
y = r sin(θ)
r is the radius of the circle
r = 4
θ is the angle made by the component of x and y:
tanθ = y/x
tanθ = r/r; x = y = r
tanθ = 1
θ = 45 degrees
Thus, the polar form of the equation x² + y² = 16 is x = 4 or y = 4 or r = 4 ( x = y = r = 4) option (B) is correct.

So firstly, we have to determine what 6% of $12.50 is. You can do this by multiplying 12.50 and 6% (or 0.06 in decimal form) to get 0.75, or 75 cents. 75 cents is your 6% sales tax.
Next, add up 12.50 and 0.75 to get $13.25. $13.25 is the total cost of the item.
