5. A video store charges a monthly
membership fee of $12.00, but charges to
rent each movie is only $1.50 per movie.
Another store has no membership fee, but it
costs $3.00 to rent each movie. How many
movies need to be rented each month for
the total fees to be the same from either
company?

Answers

Answer 1

Answer:

8

Step-by-step explanation:

With the information from the question, you create the equation 1.5x+12=3x where x represents the fee per movie. subtract 1.5x on each side, leaving you with 12=1.5x, and divide 12 by 1.5, leaving you with the answer of x=8.

Answer 2
The answer is 8 ............

Step-by-step explanation:

We need two points to find the slope

( -1,0) and ( 2,3)

We can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 3-0)/(2 - -1)

  = (3-0) / ( 2+1)

  = 3/3

  = 1

A triangle formed by the sides 3.8cm ,3.7 cm, and 5cm is​

Answers

It is a scalene triangle because none of the sides are the same!

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.

The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is​ acute angle triangle.

How to find the type of triangle?

By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,

For a triangle to be right angle triangle,

           [tex]c^2=a^2+b^2[/tex]

       By this law it is observed that,

For a triangle to be acute angle triangle,

         [tex]c^2<(a^2+b^2)[/tex]

For a triangle to be obtuse angle triangle,        

        [tex]c^2>(a^2+b^2)[/tex]

The sides of the given triangle are  3.8 cm ,3.7 cm, and 5 cm.

Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,

[tex]c^2=5^2\\c^2=25[/tex]

Other two sides,

[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]

Therefore,

[tex]25<28.13\\[/tex]

Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is​ acute angle triangle.

The length of a rectangular pool is 50 yards, and the width of the pool is 16 yards. What is the approximate length of the diagonal of the pool

Answers

Answer:

52.5

Step-by-step explanation:

You would use the Pythagorean theorem to solve this. Using the formula,

a^2 + b^2 = ^2

You would have an equation of 50^2 + 16^2 = c ^2.

50^2 is 2500, and 16^2 is 256.

There, you have 2500+256 = c^2

add those together, and you have 2756.

Now, you have to find the square root of 2756 (to solve 2756 = c^2)

which leaves you with 52.4976189936 . Rounded to the nearest tenth, you end up with 52.5.

#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4

#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5

#3: the second one. $4.5 < $8.4

#4: 45 times 12 = $54

Part A: The x-intercepts of the graph are (-2, 0) and (2.5, 0). 2x² - x - 10 = 0 2x² - 5x + 4x - 10 = 0 x(2x - 5) + 2(2x - 5) = 0 (x + 2)(2x - 5) = 0 x = -2, 5/2 or 2.5 Part B: The vertex is going to be the minimum of the function. The coordinates are (0.25, -10.125). Vertex = (h,k) h = midpoint of the x-intercepts (because of symmetry) h = (-2 + 5/2) = 1/4 k = f(1/4) k = 2(1/4)² - 1/4 - 10 = -81/8 Vertex: (0.25, -10.125). y-intercept: when x = 0 2(0)² - 0 - 10 = -10 Part C: To graph f(x), I would draw a line connecting the x-intercepts, vertex and the y-intercept using the points (-2,0), (0,-10), (0.25, -10.125) and (2.5,0). These points are the answers from part A and B and that is why I can use them to draw the graph.

Answer:

k = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-84 = -2(2 + 5k)

Step 2: Solve for k

Divide -2 on both sides:                    42 = 2 + 5kIsolate k term:                                    40 = 5kIsolate k:                                             8 = kRewrite:                                              k = 8

Step 3: Check

Plug in k into the original equation to verify it's a solution.

Substitute in k:                    -84 = -2(2 + 5(8))Multiply:                               -84 = -2(2 + 40)Add:                                     -84 = -2(42)Multiply:                               -84 = -84

Here we see that -84 does indeed equal -84.

∴ k = 8 is the solution to the equation.
