Check the picture below.

Answer:

The total cost is $16.96

The cost per photo is $1.06

Step-by-step explanation:

Hello!

1 roll of film costs $4.79. 1 roll of film has 16 photos. To develop the 16 photos, you need to pay $12.17.

First, let's find the total cost for the film and the development for 1 roll of film:

The total cost of 16 photos is $16.96

Now, we have to find the price per picture on the roll of film. We know that there are 16 shots on the film, so we can simply divide the total price by 16 to find the price per picture.

Divide:

The price per photo is $1.06

On a certain hot summer day 438 people use the public swimming pool the daily prices are 1.50 for children and 2.00 for adults three receipts for admission totals $817 how many children and how many adults swim in the public pool that day

[tex]c + a = 438 \\ 1.50c + 2.00a = 817\\ a = 438 - c \\ 1.50c + 2.00(438 - c) = 817 \\ 1.50c + 876 - 2.00c = 817 \\ [/tex]

1.5c+876−2c=817

Step 1: Simplify both sides of the equation.

1.5c+876−2c=817

1.5c+876+−2c=817

(1.5c+−2c)+(876)=817(Combine Like Terms)

−0.5c+876=817

−0.5c+876=817

Step 2: Subtract 876 from both sides.

−0.5c+876−876=817−876

−0.5c=−59

Step 3: Divide both sides by -0.5.

[tex]c = \frac{ - 59}{ - 0.5} [/tex]

c=118

in the first formula

[tex]a = 438 - c \\ a = 438 - 118 \\ a =320[/tex]

Answer:

10/17x-83

Step-by-step explanation:

You can't simplify the numerator.

You use the distributive property to open up 17(x-5).

17x-85

10/17x-85-2 Simplify -83 and -2

-85+2=-85

So then 10/17x-83

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Let's separate into 3 cases:

Note that we put the number of color balls we want in the numerator and the total number of color balls remaining in the denominator.

Case 1: 2 blue marbles

[tex]\frac{5}{13} * \frac{4}{12} = \frac{5}{39}[/tex]

(There were 5 blues originally, and 4 blues after 1 blue is taken out, same logic but different colors and values in case 2 and 3.)

Case 2: 2 red marbles

[tex]\frac{6}{13} * \frac{5}{12} = \frac{5}{26}[/tex]

Case 3: 2 green marbles

[tex]\frac{2}{13} * \frac{1}{12} = \frac{1}{78}[/tex]

Now add up all 3 cases and you will have the probability as required.

[tex]\frac{5}{39} +\frac{5}{26}+ \frac{1}{78} = \frac{1}{3}[/tex]

Step-by-step explanation:

To find the displacement I'll give you two ways since I don't know if you had experience with calculus. So here's both ways.

Way 1: Graph 1: Geometric Apporoach.

I'll a graph where t is x axis and v is y axis. So we have a velocity versus time graph.

Then, we graph the function

Look Above this what graph I get

Now, to find displacement,

Remeber displacement is the product of velocity and time. So here displacement is area under the curve.

We want displacement from 0 to 2. so let form the shape under the curve.

Look at the second graph, we form a triangle and we get this

Area of Triangle is 1/2 bh.

The base is 2 and the height is -6 so we get

[tex] \frac{1}{2} (2)( - 12) = - 12[/tex]

Our height is -12 because velocity is a vector so it can be negative and down is negative.

So the displacement is -12

Way 2: Calculus Way.

We can use integration to find the answer.

[tex]∫(f(x)dx[/tex]

So now we have

[tex]∫( - 3 {t}^{2} + 5)dx[/tex]

[tex]∫( - 6t)[/tex]

Now we do,

[tex]∫( - 6(0 ) + - 6(2) = - 12[/tex]

So the area under the curve is -12. Thus displacement is -12

Answer:

Step-by-step explanation:

Use the simple interest formula

Where interest = Principal * Rate * Time

A = $1,840.00

I = A - P = $240.00

Equation:
A = P(1 + rt)


Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:
A = 1600(1 + (0.05 × 3)) = 1840
A = $1,840.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,600.00 at a rate of 5% per year for 3 years is $1,840.00.

By definition, -6 is the additive inverse of 6, which is that number that when added to 6 gives zero.

Answer:

-3=3a +6

-3a=6+3

a=-3

so the answer would be -3

Answer:

See below

Step-by-step explanation:

Integrating a function basically means you are taking the inverse of finding a derivative of the function. Integration is used to find the area under a curve or multiple curves, or even volume.

For instance, [tex]\int\limits^ {}2x \, dx=x^2+C[/tex] because the derivative of [tex]x^2[/tex] is [tex]2x[/tex].

Answer:

Step-by-step explanation:

Let x represent the length of the rectangle. The the width is (4x+2) and the area is ...

  x(4x+2) = 342

  2x² +x - 171 = 0 . . . . . divide by 2, rearrange to standard form

  (2x +19)(x -9) = 0 . . . factor

  x = -19/2 or +9 . . . . . the length is the positive solution: 9

  (4x+2) = 4(9) +2 = 38 . . . . find the width from the length

The length of the rectangle is 9 meters. The width is 38 meters.

Answer:

Symbols of inclusion are symbols used in mathematical expressions that group terms or factors together. They indicate that when we are simplifying expressions, we are to perform what's inside the symbols first. The three types of symbols of inclusion are parentheses, brackets, and braces.

[tex]Midpoint=\left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\=\left(\dfrac{-6-1}{2},\dfrac{-1-6}{2} \right)\\\\\\=\left(\dfrac{-7}{2},\dfrac{-7}{2} \right)\\\\\\[/tex]

= (-3.5 , -3.5)

Answer:

[tex]\boxed{\sf{(-3.5 , -3.5)}}}[/tex]

Step-by-step explanation:

This problem must be solved using the midpoint formula, which is similar to a slope formula.

Midpoint formula: [tex]\sf{(X_1,Y_1)}(X_2,Y_2)[/tex]

[tex]\sf{(\dfrac{x_2+x_1}{2},\quad \dfrac{y_2+y_1}{2})}[/tex]

y2=(-6)

y1=(-1)

x2=(-1)

x1=(-6)

Rewrite the problem and then solve it.

[tex]\left(\dfrac{-1-6}{2},\:\dfrac{-6-1}{2}\right)=-\sf{\dfrac{7}{2}, -\dfrac{7}{2}}[/tex]

Dividing is another option.

-7/2=-3.5

(-3.5, -3.5)

As a result, the final answer is (-3.5, -3.5).

I hope this helps! Let me know if my answer is wrong or not.

I think your question seems to be ;

[tex]{\:\implies \quad \sf 3a-\dfrac23 +2a+\dfrac32 =a+\dfrac76}[/tex]

So I will be solving for that ;

[tex]{\:\implies \quad \sf 3a+2a+\left(\dfrac32 -\dfrac23\right)=a+\dfrac76}[/tex]

[tex]{\:\implies \quad \sf 5a+\left(\dfrac{9-4}{6}\right)=a+\dfrac76}[/tex]

[tex]{\:\implies \quad \sf 5a+\dfrac56 =a+\dfrac76}[/tex]

[tex]{\:\implies \quad \sf 5a-a=\dfrac76 -\dfrac56}[/tex]

[tex]{\:\implies \quad \sf 4a=\dfrac{7-5}{6}}[/tex]

[tex]{\:\implies \quad \sf 4a=\dfrac26}[/tex]

[tex]{\:\implies \quad \sf 4a=\dfrac13}[/tex]

[tex]{\:\implies \quad \sf a=\dfrac{1}{3\cdot 4}}[/tex]

[tex]{\:\implies \quad \bf \therefore \quad \underline{\underline{a=\dfrac{1}{12}}}}[/tex]

The large bag of popcorn cost $8.50 while the small bag of popcorn cost $5

Variables are letters use to represent number in an equation. Therefore,

Let

A large bag of popcorn cost $3.50 more than a small bag of popcorn. Therefore,

A movie theatre sells 12 large bags of popcorn and 25 small bags of popcorn for $227. Therefore,

Let's combine the equation

y - x = 3.50

12y + 25x = 227

12y  - 12x = 42

37x = 185

x = 185 / 37

x = 5

Therefore,

y = 3.50 + 5

y = 8.50
