can someone help out ?? question is "The cost of Caroline’s cell phone plan is shown below in the table. What is the equation that best represents the the total cost, y, after x number of months?

Step-by-step explanation:

sin2x - sinx = 0

2sinxcosx - sinx = 0

(Double Angle Formula)

sinx(2cosx - 1) = 0

Either sinx = 0 or cosx = 1/2.

When sinx = 0,

x = 0 or x = π.

When cosx = 1/2,

x = π/3 or x = 5π/3.

Hence the solutions are

x = 0, x = π/3, x = π or x = 5π/3.

Answer:

780

Step-by-step explanation:

So 5% is 39 so 5% x 20 is 100% do the same with the 39 so do

39 x 20 = 780

I think its the third one but i might be wrong

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

Given ratio of males to females at a party is 3 : 5.

Let the numbers of males and females be 3x and 5x respectively.

According to the given description:

No of females = No of males + 13

Therefore,

5x = 3x + 12

5x - 3x = 12

2x = 12

x = 12/2

x = 6

No of people at the party

= 3x + 5x

= 8x

= 8*6

= 48

iI think that c because it is inside the integers are inside the rationals

Answer:

c) = (-180)

d) = (-81)

this is the answer that is to be written in the boxes

Answer:

[tex]\frac{25}{100}[/tex]

Step-by-step explanation:

Hey there !!!!!

to find the correct answer to this question  you just divide :

the options are  25/10 , 2/5 , 10 / 25 and 25/100

so, you divide each one of them :

25/10 = 25 ÷ 10

2/5 = 2 ÷ 5

10/25 = 10÷25

25/100 = 25÷100

if you divide each one of them:

25 ÷ 10 = 2.5

2 ÷ 5 = 0.4

10÷25 = 0.4

25÷100 = 0.25

therefore:

25/100 is the answer

have a wonderful day

a dunno if thats wha ya meant but theres already an answer filled in there a think

Answer:

c = 17

Step-by-step explanation:

a^2 + b^2 = c^2

= 8*8 + 15*15

= 64 + 225

= 289

= 289 SQUARED

= 17

Answer:

i THINK it is 15. im so so so super sorry if im wrong-have a nice day!

Answer:

[tex]x^{2} +5x[/tex]

Step-by-step explanation:

A = length x width

l = x + 5

w = x

A = x(x + 5)

[tex]A=x^{2} +5x[/tex]

Answer:

13

Step-by-step explanation:

Replace X with 2

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)​

g(x) = 3(2)^2 – 2(2) + 5

Next conduct PEMDAS

Exponents are first so solve 2^2 which is 2 x 2 = 4

g(x) = 3(4) – 2(2) + 5

Next step is multiplication multiply 3 x 4 and 2x2

g(x) = 12 – 4 + 5

conduct adding and subtracting left from right

g(x) = 13

Answer:y=2x

(Slope=2)

Step-by-step explanation:

The ratio is 1 to 2y is to times x y=2x

Answer:

(a) I'm pretty sure it's $71.75

(b) the total would be $771.75 if i calculated it right...

Answer: 8 and 2

Step-by-step explanation:

this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo

Answer:

So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.

And it can’t be greater then 10 becuase if you do add them it won’t be 10

SO it has to be between 1-10

So what equals 10?

5/5

2/8

8/2

6/4

4/6

3/7

7/3

Now 5 and 5 is out cause if subtracted its 0

2/8  and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.

final answer the two numbers are 8 and 2

Step-by-step explanation:

the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.

The lowest common multiple of 63 is 3. 63/3 = 21

The lowest common multiple of 42 is 2 = 42/2 = 21

[tex] \frac{6}{87} \: of \: 45638 \\ \\ = \frac{6}{87} \times 45638 \\ \\ = 6 \times 524.574713 \\ \\ = 3,147.44828[/tex]

Answer:

r = 0.16

Step-by-step explanation:

C = 2·π·r

1 =  2·π·r

1/2 =  π·r

0.5 =  π·r

0.5 / 3.14 = r

0.16 = r

Answer:

-4

Step-by-step explanation:

because the line is going from top to bottom it is negative

you take the rise ( the Y value) / the run (the X Value)

the Y and X value can be pulled from any two points

Answer:

The solution of the equation    y = 36

Step-by-step explanation:

Explanation:-

Given equation -3x-y =-51

Given that x =15 in equation -3x-y=-51

                 ⇒        - 3(15) - y = -51

                ⇒         - 15 - y =-51

                 ⇒         -15+ 51 = y

               ⇒            y = 36

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

[tex]s=\dfrac{48}{b}[/tex]

Hence, the required expression is (48/b).
