2) d. 8 child tickets

Step-by-step explanation:

1) added 90 minutes until 530

2) 118-19=99 99÷12=8.25

Answer:

46 minutes

Step-by-step explanation:

Sorry about not answering your question sooner, but here is your answer:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:

15 - 6.72 = 8.28

Then, we divide this number by 0.18:

8.28 / 0.18 = 46

So, Tammy's call lasted 46 minutes

Hope this helps :)

Step-by-step explanation:

Answer:

12.60

Step-by-step explanation:

9 dollars divided by 5 lightbulbs is 1.8

so 1.80 dollars × 7 lightbulbs = 12.60

9÷5=1.8

1.8×12.60

Easy buddy...

[tex]5x - 15 = 3x + 7[/tex]

Subtract the sides of the equation plus 15

[tex]5x = 3x + 7 + 15[/tex]

[tex]5x = 3x + 22[/tex]

Subtract the sides of the equation minus 3x

[tex]5x - 3x = 22[/tex]

[tex]2x = 22[/tex]

Divided the sides of the equation by 2

[tex]x = \frac{22}{2} \\ [/tex]

[tex]x = 11[/tex]

Answer:

C

Step-by-step explanation:

Answer:

The answer is c

Step-by-step explanation:

Answer:

y=(2x^2+24x)+25

y=2x(x^2+12x)+25

y=2x(x^2+12x+36)+25-2x(36)

Y=2x(x+6)^2+25-72

Y=2x(X+6)^2-47

Step-by-step explanation:

sorry it was late

Answer: y=2(x+6)²-5

Step-by-step explanation: First you find the coefficient of x^2, which is 2, then take out 2 as a factor, 24/2 which will equal to 12. After that do 47 divided by 2  if you calculate that it will equal to 23.5.  y=2(x²-12+23.5)  y =2(x²-12x+23.5)

Next Step: Figure out the coefficient of x. To make it easier,look what is in front of x as you can see it is 12. Then you divide 12/2 which is 6. Then square 6, which is 36. Then you add and subtract 36. To write the first three terms as a square, you do ( x+6)^2. Then do -36 + 23.5 if you calculate that it will get you wil get -12.5 . Now that you have calculated that distribute 2, then do 2 times -12.5 which is -12.5. This is how it shoud look like y=2(x+6)² -12.5.  

Answer:

Step-by-step explanation:

i just subtracted 3,000 with 50

There are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

What is random shuffle of songs?

Shuffle play is a type of music playback in which all tracks are selected at once and songs are played in a random order. Media player software, digital audio players, and CD players all frequently have it.

Given: You have 3,000 songs downloaded to your mobile phone.

Of these songs, 50 songs are by your favorite artist.

So, the number of songs would you have to listen in a row before you heard a song by your favorite artist are,

3000 - 50 = 2950.

Therefore, there are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

Answer:

Step-by-step explanation:

The missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even and sine function is odd respectively.

Given:

The given expression is [tex]\sin (x-y)[/tex].

To find:

The justification for each step.

Explanation:

Cofunction identities:

[tex]\sin\left(\dfrac{\pi}{2}-x\right)=\cos x[/tex]

[tex]\cos\left(\dfrac{\pi}{2}-x\right)=\sin x[/tex]

Cosine difference identity:

[tex]\cos(x-y)=\cos x\cos y+\sin x\sin y[/tex]

Cosine function is even, so [tex]\cos(-x)=\cos x[/tex].

Sine function is odd, so [tex]\sin(-x)=-\sin x[/tex].

We have,

[tex]\sin (x-y)[/tex]

[tex]=\cos\left|\dfrac{\pi}{2}-(x-y)\right|[/tex]                                             Step 1: Cofunction identity

[tex]=\cos\left|\dfrac{\pi}{2}-x+y\right|[/tex]                                                 Step 2: Distributive property

[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)+y\right|[/tex]                                            Step 3: Associative property

[tex]=\cos\left|\left(\dfrac{\pi}{2}-x\right)-(-y)\right|[/tex]                                        Step 4: Factoring out   

[tex]=\cos\left(\dfrac{\pi}{2}-x\right)\cos(-y)+\sin\left(\dfrac{\pi}{2}-x\right)\sin(-y)[/tex]       Step 5: Cosine difference identity

[tex]=\sin(x)\cos(-y)+\cos(x)\sin(-y)[/tex]                           Step 6: Cofunction identity

[tex]=\sin(x)\cos(y)-\cos(x)\sin(y)[/tex]                                Step 7: Cosine function is even, sine function is odd

Therefore, the missing reasons are Cofunction identity, Cosine difference identity, Cofunction identity, Cosine function is even, sine function is odd respectively.

Miles that alex can drive is 100

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

The calculation is as follows;

Number of days alex rents a car = 1 day

The charge for the car = $18 plus $0.12 per mile

Alex wants to spend; $30

The number of miles he will drive can be calculated as follows

= $30 - $18

= $12

= 12÷0.12

= 100

Therefore, if Alex spends $30 he will drive for 100 miles

Answer: range: 3, domain: 4

Step-by-step explanation:

the range of a problem is basically the difference between the smallest and the largest y value. the largest y value here is 6 and the smallest is 3, so 6-3 = 3 -> 3 is your range! now for domain: the domain of a problem is the difference between the smallest and largest x value. the largest x value is 2 and the smallest is -2, so 2 - -2 = 4 -> the domain is 4! hope this helped!
