A telephone calling card charges a connection fee, plus a charge per minute. A 10-minute call costs $2.99. A 15-minute call costs $3.99. What is the cost for a 30-minute phone call?

Answer:

negative twelve

Step-by-step explanation:

the slope is -1, so one must go down as the other goes up. since the x value has increased by 3, the y value must decrease by three

Answer:

The train travels at 66 miles per hour.

Step-by-step explanation:

Given that:

Time taken by train = 8 hours

Distance covered by train in 8 hours = 528 miles

Unit rate is defined by the distance travelled by train in one hour.

Therefore, we will divide the total time taken by train to distance covered by train in that time.

Unit rate = [tex]\frac{Distance\ travelled}{Time\ taken}[/tex]

Unit rate = [tex]\frac{528}{8}[/tex]

Unit rate = 66 miles per hour

Hence,

The train travels at 66 miles per hour.

Answer:Alexia swam  7,560meters in 2 weeks

Step-by-step explanation:

Step 1

7 days = 1 week

therefore 2 weeks = 7 x 2 = 14 days

Step 2

Each day  Alexia swam =  0.54 kilometres

So in 14 days( 2 weeks) She swam = 14 x 0.54 km= 7.56km

Answer is needed in meters

so 1000 m = 1km

Therefore 7.56 km = 7.56km x 1000=7,560meters

22/33=4/6

Step-by-step explanation:

(22/33)=(4/6) is the following equations are not a proportion. Option B is correct.

A ratio is an ordered pair of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two ratios are specified to be equal.

The two numbers in ratio in numerator and denominator is divided by the same number and obtained as the whole number as;

[tex]\rm \frac{a}{b} = \frac{2 \times a}{2 \times b}[/tex]

(22/33)=(4/6) is the following equations are not a proportion.

Hence, option B is correct.

sorry but their is no picture its black...

Answer:

Option D is correct

Step-by-step explanation:

For this question we would need the equation of line since this is a multiple choice question you wouldn't have enough time to find out the equation so we need to be FAST

If we see all the four options at first glance option C or option D seem correct because the line represents a rise in values of x and y respectively, which means x increases with respect to y. So the slope/gradient in other words m should be positive so option A and B are ruled out because the equation of line is written as

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept so seeing the graph our equation of line should be

[tex]y=mx-2[/tex]

where b = -2 because value of b corresponds to y-intercept which means the where the graph intersects the y-axis in this case its -2

where m is positive in this case 5 thus

[tex]y=5x-2[/tex]

if we try to rearrange the four choices option C and D give us the above equation and option A and B give us

[tex]y=-5x+2[/tex]

which is wrong !

Now, regarding the inequality sign the graph represents

[tex]y=5x-2[/tex]

and the area which is shaded in blue is the region lower the line which means it should be

[tex]y\leq 5x-2[/tex]

in this case its D if we rearrange it

I have two images so you understand it better visually

As you can see in both forms are shaded region is the same so option D is correct

30

Step-by-step explanation:

let x = number of pounds of jelly beans

    y = number of pounds of almonds .

then , 4x + 8y =33

          2x + 3y = 13

multiply the second equation by -2 to get the system :

4x + 8y =33

-4x - 6y = -26

adding the equations ,we get 2y=7. so y=3.5

substitute for y in either of the given equations : 2x + 3 (3.5) =13

+ 10.5=13

     2x =2.5

        x=1.25

answer : A pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.

Answer:

a. The new number created is 265,134.

b. The new number created is 625,314.

c. The new number created is 652,314.

d. The new number created is 462,513.

e. The new number created is 253,416.

Step-by-step explanation:

Note: The first question is not correctly and fully stated. It is therefore restated as the questions are answered as follows:

a. Move the 2 so it is worth 10 as much.

From 625,134, the 2 implies 20,000.

If we move the 2 so it is worth 10 as much, it implies that 20,000 is multiplied by 10 and the answer is as follows:

20,000 * 10 = 200,000

The answer implies that 2 becomes the first number and the new number created from 625,134 is as follows:

The new number created is 265,134.

b. Move the 3 so it is worth 10 times as much.

From 625,134, the 3 implies 30.

If we move the 3 so it is worth 10 as much, it implies that 30 is multiplied by 10 and the answer is as follows:

30 * 10 = 300

The answer implies that 3 becomes the fourth number and the new number created from 625,134 is as follows:

The new number created is 625,314.

c. Move the 5 so it is worth 50,000.

This implies that 5 becomes the second number and the new number created from 625,134 is as follows:

The new number created is 652,314.

d. Move the 4 so its value changes to 4 X 100,000

This implies that 4 is now 400,000 and it now becomes the first number. The new number created from 625,134 is as follows:

The new number created is 462,513.

e. Move the 1 and the 6 so that the sum of their values is 16.

This implies the one becoms 10 and the 6 becomes just 6.

As a result, this implies that the 1 now becomes the fifth number and the 6 now become the last number. The new number created from 625,134 is now as follows:

The new number created is 253,416.

Answer:

Step-by-step explanation:

Edge 2021

cos(2A) + cos(2A) cot(2A) = cot(2A)

cos(2A) + cos(2A) cot(2A) - cot(2A) = 0

cot(2A) sin(2A) + cos(2A) cot(2A) - cot(2A) = 0

cot(2A) (sin(2A) + cos(2A) - 1) = 0

cot(2A) = 0   or   sin(2A) + cos(2A) - 1 = 0

cot(2A) = 0   or   sin(2A) + cos(2A) = 1

cot(2A) = 0   or   sin(2A) cos(π/4) + cos(2A) sin(π/4) = 1/√2

cot(2A) = 0   or   sin(2A + π/4) = 1/√2

[2A = cot⁻¹(0) + nπ]   or

[2A + π/4 = sin⁻¹(1/√2) + 2nπ   or   2A + π/4 = π - sin⁻¹(1/√2) + 2nπ]

(where n is any integer)

[2A = π/2 + nπ]   or

[2A + π/4 = π/4 + 2nπ   or   2A + π/4 = 3π/4 + 2nπ]

[A = π/4 + nπ/2]   or

[2A = 2nπ   or   2A = π/2 + 2nπ]

[A = π/4 + nπ/2]   or

[A = nπ   or   A = π/4 + nπ]

A = (1 + 2n) π/4   or   A = nπ   or   A = π/4 + nπ

Answer:

y=0

Step-by-step explanation:

So you would do -4(6y-3) and divide that by -4

then you would do 12 and divide that by -4

or

You could do

-6y-3 which equals -3

then

add three to both sides like this -6y-3+3=-3+3

then simplify it to -6y=0

then divide -6y over -6 and 0 over -6

then it will simplify to 0

Answer:

D. 12) 25.68 = 2.14

Step-by-step explanation:

Given :

Divisor = 1.2

Dividend = 2.568

We can make the divisor a whole number by multiplying the divisor by 10,

i.e. Divisor = 1.2 x 10 = 12

Similarly , dividend = 2.568 x 10 = 25.68

Therefore,

         2.14            

 12 | 25.68

  (-)  24                        

           16

      (-) 12                      

             48

      (-)  48                

             0

Hence the answer is 2.14
