The cost of a telephone call is $0.75 + $0.25 times the number of minutes. Write an algebraic expression that models the cost of a telephone call that lasts t minutes.
The algebraic expression that models the cost of a telephone call that lasts t minutes would be:
0.75 + 0.25t
0.75 + 0.25t
explain
The algebraic expression 0.75 + 0.25t represents the cost of a telephone call that lasts t minutes.
In the expression, 0.75 represents the initial cost of the call, which is a fixed fee regardless of the duration of the call.
The term 0.25t represents the additional cost per minute. Here, 0.25 is the cost per minute, and t is the number of minutes.
By multiplying 0.25 by the number of minutes (t), we calculate the additional cost based on the length of the call.
Adding the fixed cost (0.75) to the additional cost (0.25t) gives the total cost of the call.
For example, if a call lasts 10 minutes, the expression evaluates to:
0.75 + 0.25(10) = 0.75 + 2.5 = 3.25
Therefore, the cost of a 10-minute call would be $3.25.

Therefore, the cost of a 10-minute call would be $3.25.
so what should i put down?
You should put down the expression:
0.75 + 0.25t
0.75 + 0.25t
write an algebraic expression that models the cost of a telephone call that lasts t minutes.
An algebraic expression that models the cost of a telephone call that lasts t minutes is:
Cost = C * t
Where C is the cost per minute of the call.
Cost = C * t
Where C is the cost per minute of the call.
The cost of a telephone call is $0.75 + $0.25 times the number of minutes
The algebraic expression that models the cost of a telephone call that lasts t minutes is:
Cost = 0.75 + 0.25t
In this expression, 0.75 represents the base cost or fixed fee for the call, and 0.25t represents the additional cost per minute. By multiplying the number of minutes (t) by 0.25 and adding it to the base cost, we can calculate the total cost of the call.
Cost = 0.75 + 0.25t
In this expression, 0.75 represents the base cost or fixed fee for the call, and 0.25t represents the additional cost per minute. By multiplying the number of minutes (t) by 0.25 and adding it to the base cost, we can calculate the total cost of the call.
Use the formula for the area of a trapezoid A=h(b1+b22)
, where A is area, b1 and b2 are the length of the bases, and h is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?
, where A is area, b1 and b2 are the length of the bases, and h is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?
To find the area of the trapezoidal field, we can use the formula for the area of a trapezoid:
A = h(b1 + b2) / 2
Given:
- height (h) = 75 ft
- base 1 (b1) = 125 ft
- base 2 (b2) = 81 ft
Using the formula, we can calculate the area:
A = 75(125 + 81) / 2
A = 75(206) / 2
A = 15450 / 2
A = 7725
Therefore, there are 7725 square feet of grass on the trapezoidal field.
A = h(b1 + b2) / 2
Given:
- height (h) = 75 ft
- base 1 (b1) = 125 ft
- base 2 (b2) = 81 ft
Using the formula, we can calculate the area:
A = 75(125 + 81) / 2
A = 75(206) / 2
A = 15450 / 2
A = 7725
Therefore, there are 7725 square feet of grass on the trapezoidal field.
