A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro what is the total
Nana76 [90]

Answer:

Total minutes = 47 Minutes

Step-by-step explanation:

A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro

Expressing the statement in mathematical terms;

Cost = 0.12x + 1.5 where x represens minutes

if the cost of the call was 7.14 euro, total minutes  = ?

7.14 = 0.12x + 1.5

7.14 - 1.5 = 0.12x

5.64 = 0.12x

x = 5.64 / 0.12 = 47

Total minutes = 47 Minutes

graph the function f (x) = x^2 + 4x -5. on the coordinate plane. (a) What are the x-intercepts? (b) What are the y-intercepts? (
Butoxors [25]

Answer:

a) (-5,0) and (1,0)

b) (0,-5)

c) minimum

See attached graph.

Step-by-step explanation:

To graph the function, find the vertex of the function find (-b/2a, f(-b/2a)). Substitute b = 4 and a = 1.

-4/2(1) = -4/2 = -2

f(-2) = (-2)^2 + 4(-2) - 5 = 4 - 8 - 5 = -4 - 5 = -9

Plot the point (-2,-9). Then two points two points on either side like x = -1 and x = -3. Substitute x = -1 and x = -3

f(-1) = (-1)^2 + 4 (-1) - 5 = 1 - 4 - 5 = -8

Plot the point (-1,-8).

f(-3) = (-3)^2 + 4(-3)  - 5 = 9 - 12 - 5 = -8

Plot the point (-3,-8).

See the attached graph.

The features of the graph are:

a) (-5,0) and (1,0)

b) (0,-5)

c) minimum

The two tables give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye.
abruzzese [7]

In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.

<h3>What is ratio of two numbers?</h3>

The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.

There are two tables which give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye. The table is given below;

  • Green #1 is made by mixing blue and yellow in a ratio of 2 : 3.
  • Green #2 is made by mixing blue and yellow in a ratio of 1 : 2.

The first one has 2 parts of blue at 3 parts of yellow. In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2.

In grade two the blue part is half of the yellow part. This means that green #1 is bluer shade of green than Green # 2.

Hence, in the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.

Margaret [11]

The computation shows that the average monthly amount is 61.64.

<h3>How to calculate the value?</h3>

The amount that's left will be:

= 3314.85 + (2 × 926.65) - (1800 × 2) - 1075

= 3314.85 + 1853.3 - 3600 - 1075

= 493.15

The average monthly amount will be:

= 493.15/8

= $61.64
