a cell phone company has a basic monthly plan of $40plus $0.45 for many minutes ised over 700. John was charged a total of $48.10. Write an equation to determine how many minutes he must have used during the month.

Answers

Cost of month plan = $40

Cost of minutes used = $0.45 after 700 minutes

Total cost = $48.10

Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)

------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
0.45x = 48.10 + 275
0.45x = 323.10
x = 323.10 ÷ 0.45
x = 718

For the level 3 course, exam hours cost twice as much as workshop hours, workshop hours cost twice as much as lecture hours. How much are lectures per hour?

Answers

Answer

Cost of lectures = $7.33 per hour

Explanation

Let [tex]e[/tex] the cost of the exam hours

Let [tex]w[/tex] be the cost of the workshop hours

Let [tex]l[/tex] be the cost of the lecture hours.

We know from our problem that exam hours cost twice as much as workshop, so:

[tex]e=2w[/tex] equation (1)

We also know that workshop hours cost twice as much as lecture hours, so:

[tex]w=2l[/tex] equation (2)

Finally, we also know that 3hr exams 24hr workshops  and 12hr lectures cost $528, so:

[tex]3e+24w+12l=528[/tex] equation (1)

Now, lets find the value of [tex]l[/tex]:

Step 1.  Solve for [tex]l[/tex] in equation (3)

[tex]3e+24w+12l=528[/tex]

[tex]12l=528-3e-24w[/tex] equation (4)

Step 2. Replace equation (1) in equation (4) and simplify

[tex]12l=528-3e-24w[/tex]

[tex]12l=528-3(2w)-24w[/tex]

[tex]12l=528-6w-24w[/tex]

[tex]12l=528-30w[/tex] equation (5)

Step 3. Replace equation (2) in equation (5) and solve for [tex]l[/tex]

[tex]12l=528-30w[/tex]

[tex]12l=528-30(2l)[/tex]

[tex]12l=528-60l[/tex]

[tex]72l=528[/tex]

[tex]l=\frac{528}{72}[/tex]

[tex]l=\frac{22}{3}[/tex]

a worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. THe tiles are square with side lengths 1 1/3 feet. How many tiles are needed to cover the entire floor?

Answers

area of room: 12 x 15 = 180 square feet
 area of 1 tile = 1 1/3 x 1 1/3 = 1.78 square feet
 round to 1.8

180 / 1.8 = 100 tiles are needed

Answer:

102 tiles needed to cover the entire floor.

Step-by-step explanation:

Given : A worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. The tiles are square with side lengths [tex]1\frac{1}{3}[/tex] feet.

To find : How many tiles are needed to cover the entire floor?    

Solution :

A rectangular room that is 12 feet by 15 feet.

The area of the room is [tex]A=L\times B[/tex]

[tex]A_r=15\times 12[/tex]

[tex]A_r=180\ ft^2[/tex]

The tiles are square with side lengths [tex]1\frac{1}{3}=\frac{4}{3}[/tex] feet.

The area of the tile is [tex]A_t=s^2[/tex]

[tex]A_t=(\frac{4}{3})^2[/tex]

[tex]A_t=\frac{16}{9}\ ft^2[/tex]

Number of tiles needed to cover the entire floor is

[tex]n=\frac{A_r}{A_t}[/tex]

[tex]n=\frac{180}{\frac{16}{9}}[/tex]

[tex]n=\frac{180\times 9}{16}[/tex]

[tex]n=101.25[/tex]

Therefore, Approximately 102 tiles needed to cover the entire floor.

If the endpoints of the diameter of a circle are (−10, −8) and (−6, −2), what is the standard form equation of the circle?

Answers

Final answer:

The standard form equation of the circle with endpoints (-10, -8) and (-6, -2) is (x + 8)^2 + (y + 5)^2 = 13.

Explanation:

To find the standard form equation of a circle, we need to find the center and the radius. Since the endpoints of the diameter are given, we can find the center by finding the midpoint of the diameter. The x-coordinate of the center is the average of the x-coordinates of the endpoints, and the y-coordinate of the center is the average of the y-coordinates of the endpoints. The radius is half the length of the diameter. Once we have the center and radius, we can plug them into the standard form equation of a circle, which is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

Step 1: Find the midpoint of the diameter using the formula:
(x, y) = ((x1 + x2) / 2, (y1 + y2) / 2)
(x, y) = ((-10 + -6) / 2, (-8 + -2) / 2) = (-16 / 2, -10 / 2) = (-8, -5)

Step 2: Find the radius by halving the length of the diameter:
Length of the diameter = √((x2 - x1)^2 + (y2 - y1)^2) = √((-6 - -10)^2 + (-2 - -8)^2) = √(16 + 36) = √(52)
Radius = √(52) / 2 = √(13)

Step 3: Plug the center and radius into the standard form equation of a circle:
(x + 8)^2 + (y + 5)^2 = 13

The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
A. 264

Answers

88+88= 176 Two weeks
176+88= 263 Three weeks
264+88=352 Four weeks
352+88=440 Five weeks
440+88=528 Six weeks
The answer is C. 

The number of wildflowers is doubling each week. Starting with 88 blooms in the first week and 176 in the second, the pattern suggests that there will be 2816 flowers after six weeks.

The student is asking about a pattern of growth in the population of wildflowers. The flowers began blooming with 88 blooms and by the second week, there were 176 flowers in bloom. This indicates that the number of flowers is doubling each week. To find the number of flowers after six weeks, we can establish a pattern of growth and calculate the number for the sixth week.

We can see that from week 1 to week 2, the blooms doubled (88 x 2 = 176). If this pattern continues, the blooms will double each week.

Let's calculate the number of blooms for each week up to six weeks:

Week 1: 88 flowers

Week 2: 176 flowers (88 x 2)

Week 3: 352 flowers (176 x 2)

Week 4: 704 flowers (352 x 2)

Week 5: 1408 flowers (704 x 2)

Week 6: 2816 flowers (1408 x 2)

given the geometric sequence with the first three terms shown as (2,10,50..) answer the following questions:

Write a recursive definition for the sequence

What is the 10th term of the sequence?

Answers

The recursive definition of the sequence is :

[tex]\bf a_n = 2(5)^{n-1}[/tex]


The 10th term is:

[tex]a_{10} = 2(5)^{10-1}[/tex]

[tex]a_{10} = 2(5)^9[/tex]

[tex]\bf a_{10} = 3906250[/tex]

Final answer:

The recursive definition for the given geometric sequence is an = 5an-1, with a1 = 2. Using the geometric formula to find the 10th term, we calculate the 10th term to be 3906250.

Explanation:

The given sequence is a geometric sequence, in which each term after the first is found by multiplying the previous term by a constant ratio. In this case, the ratio is obtained by dividing the second term by the first term. Therefore, the recursive formula for the given geometric sequence is an = 5 × an-1, with the first term a1 = 2.

To find the 10th term of the sequence, we use the formula: an = a1 × r(n-1), where r is the common ratio and n is the term number. Substituting the given values we get a10 = 2 × 5(10-1) = 2 × 59.

Calculating this we find that the 10th term of the sequence is 2 × 1953125 = 3906250.

If you multiply/divide the numerator and denominator of a fraction by the same number, you will get an equivalent fraction.

For the first one, 6 is in the new numerator. Let's divide this by the original numerator to see what they did.

30/6 = 5

So they divided the numerator by 5. To get an equivalent fraction, we must do the same to the denominator.

35/5 = 7

So our new equivalent fraction is 6/7.

For the second one, the new denominator is 5. Let's see what they did to get this.

40/5 = 8

So they divided the denominator by 8 to get 5, let's do the same to the numerator:

8/8=1

So we have 1/5.

For the last one, they have 4 in the new denominator. Let's see what they did to get this denominator:

20/4 = 5

So they divided the denominator by 5, let's do the same thing to the numerator:

15/5 = 3

So we have 3/4.

(total bill) = (charge before tax)*(1 +(tax rate))
(total bill) = ((total bill) -tax)*(1 + (tax rate))

Solving for tax rate, we get
.. (tax rate) = (total bill)/((total bill) - tax) -1
