One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20 per month. Write and solve an equation to determine after how many months the cost is the same

Answers

Answer 1

Answer:

The cost would be same after 3 months.

Step-by-step explanation:

Given that:

Charges of first company;

Sign up fee = $76

Per month charges = $40

Let,

x be the number of months

y be the total cost.

y = 40x + 76      Eqn 1

Charges of second company;

Sign up fee = $136

Per month charges = $20

y = 20x + 136     Eqn 2

For same cost,

Eqn 1 = Eqn 2

40x + 76 = 20x + 136

40x-20x = 136 - 76

20x = 60

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{60}{20}\\x=3[/tex]

Hence,

The cost would be same after 3 months.

21.2 cm is the right answer.

Step-by-step explanation:

tan(θ)=o/a

tan(23)=17/x

divided by x on both sides to equal

x(letter) x tan(23)=17

and then on the calculator you type in 17/tan(23)

Avery earned a raise of an additional $2.50 per hour. Initially, she started at $10.00 an hour. What is the percent increase in Avery’s hourly pay?

Answers

Answer: 25%

Explanation:
1. Turn it into a fraction (2.50/10)
2. Divide the numerator (2.50) by the denominator (10). (2.50÷10=0.25)
3. Convert the decimal (0.25) into a percentage by multiplying it by 100 and placing “%” at the end. (0.25x100=25%)

A small aircraft flies a 2160-mi round trip in a 45 mi/h wind. Find the average rate of speed for the trip if the aircraft can fly 225 mi/h with no wind.

Answers

9514 1404 393

Answer:

  216 mi/h

Step-by-step explanation:

The time for the trip with the wind is ...

  (1080 mi)/(225 +45 mi/h) = 4 h

The time for the trip against the wind is ...

  (1080 mi)/(225 -45 mi/h) = 6 h

The average speed for the entire round trip is ...

  (2160 mi)/(4 +6 h) = 216 mi/h

What is the solution to the system of equations below?
y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)

Answers

Answer:

(-10,-7)

Step-by-step explanation:

the given equations: y=-3 and x=-10

we can substitute the x in the first equation as -10.

y=(2/5×-10)-3

simplify

y=(2/1*-2)-3

y=-4-3

y=-7

the y value is -7

we actually have the x value given as -10 (in the system)

So the answer is (-10,-7)

Answer: -4

Step-by-step explanation:

13 - 9 = 4

9 - 5 = 4

so, we can see that it is decreasing by 4 each time.

Answer:

common difference is -4

Step-by-step explanation:

The common difference is the amount we add  between terms

13 + d = 9

Subtract 13 from each side

13+d-13 = 9-13

d = -4

Check

9+d = 5

9 + -4 = 5

5= 5

This is true so the common difference is -4

x + y =3
5x + y = 15

Answers

Step-by-step explanation:

x + y = 3. => y = 3 - x

5x + y = 5x + (3 - x) = 15.

=> 4x + 3 = 15

=> 4x = 12, x = 3.

Therefore y = 3 - (3) = 0.

The solutions are x = 3 and y = 0.

Answer:

Step-by-step explanation:

x+y=3

5x+y = 15

I method:

y = 3 - x. substitute this in 2nd equation

5x + (3-x) = 15

5x + 3 - x = 15

4x = 12

x=3

y=0

II method:

subtracting 2nd equation and 1st equation we get

4x +0y = 12

x = 3

y = 0

The prism shown has a volume of 35 cm'.
Work out h, the height of the triangular cross section.
h
7 cm
4 cm​

Answers

That is an answer......

The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

What is prism ?

Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.

And,

Volume of prism [tex]= Base\ Area\ *\ Length[/tex]

We have,

Volume of prism [tex]=35 cm^3[/tex]

Length of prism [tex]=7cm[/tex]

Height of prism [tex]=h\ cm[/tex]

We also have,

Base of triangle [tex]=4\ cm[/tex]

One of the side of triangle [tex]=5\ cm[/tex]

As we have Triangular prism so Base area of prism will be the area of triangle.

so,

Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]

                          [tex]=\frac{1}{2} * 4*h[/tex]

Area of triangle [tex]=2h[/tex]

Now,

Volume of prism [tex]= Base\ Area\ *\ Length[/tex]

                       [tex]35=2h*7[/tex]

                        [tex]h=\frac{5}{2}[/tex]

                         [tex]h=2.5 \ cm[/tex]

So, the height of prism is [tex]2.5\ cm[/tex] .

Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .
