A phone company has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 410 minutes, the monthly cost will be $71.50. If the customer uses 720 minutes, the monthly cost will be $118. Find a linear equation for the monthly cost of the cell plan as a function of x, the number of monthly minutes used.

Answers

Answer:

Linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Step-by-step explanation:

Let u denotes a flat monthly fee and v denotes amount charged per minute.

As the monthly cost is $71.50 if a customer uses 410 minutes,

[tex]71.50=u+410v[/tex]     (i)

As the monthly cost is $118 if a customer uses 720 minutes,

[tex]118=u+720v[/tex]       (ii)

Subtract (i) from (ii)

[tex]118-71.50=u+720v-u-410v\\46.5=310v\\v=\frac{46.5}{310}\\ v=0.15[/tex]

Put [tex]v=0.15[/tex] in (i)

[tex]71.50=u+410(0.15)\\71.50=u+61.5\\u=71.50-61.5\\u=10[/tex]

As x denotes the number of monthly minutes used,

linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Phone Case Heaven is a store that sells phone cases and accessories at great low prices! The cost of buying c phone cases at x dollars per case and p pop sockets at y dollars each is represented by T=cx+py, where T is the total cost.

Suppose you have $24 and you plan to buy 2 pop sockets at $2.00 each. Which equation represents the number of phone cases you can buy if each phone case costs $4.50?

Answers

Answer:

(24-4.00)-4.50/20

Step-by-step explanation: 24 minus 4 would be 20 and you could buy 4 phone cases because 20 divided by 4.50 is 4.4 so 4 times 4 is 16 plus the 2.00 dollars extra from the .50 in the 4.50 so it would be you can buy 4 phone cases.

A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas tank, the driver got on a highway and drove for a while.

The sum of two numbers is 4 times their difference. If one exceeds the other by 8, what are the numbers?

Answers

Answer:

12, 20

Step-by-step explanation:

Let the two numbers be x and y, where x > y

According to the given information:

x + y = 4(x - y)

x + y = 4x - 4y

y + 4y = 4x - x

5y = 3x

[tex] y = \frac{3}{5}x.... (1)[/tex]

Since, one number exceeds the other by 8.

[tex] \implies x = y + 8\\\\

\implies y = x - 8.....(2)\\\\[/tex]

From equations (1) & (2)

[tex]x - 8 = \frac{3}{5} x \\ \\ 5(x - 8) = 3x \\ \\ 5x - 40 = 3x \\ \\ 5x - 3x = 40 \\ \\ 2x = 40 \\ \\ x = \frac{40}{2} \\ \\ \huge \purple{ \boxed{\implies x = 20}} \\ \\ \implies \: y = x - 8 = 20 - 8 \\ \\ \huge \pink{ \boxed{ \implies \: y = 12}}[/tex]

ANSWER THREE THROUGH FIVE , ILL GIVE YOU BRAINLIST!!!

Answers

Answer:

Step-by-step explanation:

3) diameter of penny = 19 mm

                          r = 19/2 = 9.5 mm

Area of penny = πr²

                        = 3.14 * 9.5 * 9.5

                         = 283.385

                         = 283.39 mm²

Diameter of nickel = 21 mm

                          r = 21/2 = 10.5 mm

Area of nickel  = πr²

                         = 3.14 * 10.5 *10.5

                        = 346.185

                        = 346.19 mm²

346.19 - 283.39 = 62.8 mm²

Area of Canadian nickel is greater than Canadian penny by 32.6 mm²

4)  r = 12 mm

Area of circle = πr²

                      = 3.14 * 12 * 12

                       =  452.16 mm²

5) r  = 20 cm

Area of circle =  πr²

                      = 3.14 * 20 * 20

                      = 1256 cm²
