A guitarist sets a goal to practice 200 minutes each week. If he only is going to practice 5 days during the week, which of the following amounts of average daily practice will allow him to reach his goal?

Answer:

[tex]\%Change = -28\%[/tex]

Step-by-step explanation:

Given

25 decreased to 18

Required

Determine the percentage change

This is calculated as follows:

[tex]\%Change = \frac{Initial\ Value - New\ Value}{Initial\ Value} * 100\%[/tex]

In this case:

[tex]Initial\ Value = 25[/tex]

[tex]New\ Value = 18[/tex]

So, the formula becomes

[tex]\%Change = \frac{18 - 25}{25} * 100\%[/tex]

[tex]\%Change = -\frac{7}{25} * 100\%[/tex]

[tex]\%Change = -\frac{7* 100\%}{25}[/tex]

[tex]\%Change = -\frac{700\%}{25}[/tex]

[tex]\%Change = -28\%[/tex]

Hence, the change is 28% decrease

Answer:

Milk (Cups)    |  4  |  8  |  12  |  16

Flour (Cups)  |  3  |  6  |  9   |   12

Step-by-step explanation:

Since you're doing a ratio of 4x:3y, just multiply the x value by 3/4 to get the y value. We can do this for each y value missing:

8 × ( 3 / 4 ) = 6

16 × ( 3 / 4 ) = 12

Now if you have the y value, since the ratio is 3y:4x, you multiply each y value by 4/3. We can do this for the one y value missing:

9 × ( 4 / 3 ) = 12

So, your chart should look like:

Milk (Cups)    |  4  |  8  |  12  |  16

Flour (Cups)  |  3  |  6  |  9   |   12

Answer:

500

Step-by-step explanation:

If 1% is 2.5 then 100% is 250.  Since 250 is half of a number, you went then multiply by 2 to double that number which is 500.

Answer:

56.67

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

As a fraction of the number of days in a calendar year, it will depend on whether the year is a leap year.

non-leap years have 365 days, so 31 days is 31/365 years.

leap years have 366 days, so 31 days is 31/366 years.

_____

If you're asking for the purpose of computing interest, you need to be aware that "ordinary interest" counts 360 days in a year. 31 days would be 31/360 years. "Exact interest" counts 365 days in a year, so 31 days would be 31/365 years.

In astronomy, the definitions of "day" and "year" may vary, depending on the frame of reference and what direction in space marks the boundary of the period. The precise fraction will depend on how you define these terms and where the clock is located.

The equation for the blue graph is a translation of the parent quadratic function, and this is:

g(x) = (x - 2)^2 + 1

We can see that the red graph belongs to the parent quadratic function:

f(x) = x^2

And we can see that the blue graph is a translation of that parent function.

The translations are defined as:

Horizontal translation:

For a general function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N).

If N is positive, the shift is to the left.If N is negative, the shift is to the right.

Vertical translation:

For a general function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N.

If N is positive, the shift is upwards.If N is negative, the shift is downwards.

By viewing the vertices, we can see that g(x) is a translation of 1 unit up and 2 units to the right, then the function g(x) is:

g(x) = (x - 2)^2 + 1

The correct option is D.

Answer:

P = $ 7007.08 option C

Step-by-step explanation:

given: r = 9% pa compounded monthly , n = 6 , Amount A = $ 12000

to find : P

formula used : A = P ( 1+r/1200)⁷²

P = A / (1 + r/1200)⁷²

P = (12000) / (1 + 9/1200)⁷²

P = 12000 / ( 1 + 3/400)⁷²

P = 12000 / ( 403/400)⁷²

P = 12000 / (1.0075)⁷²

P = 12000 / (1.71255)

Answer:

$18480

Step-by-step explanation:

First you find what 9% of 12,000 is. You get 1080. Then you multiply that number by 6 because it has been 6 years. Then you get 6480. You then add 6480 to 12000 and get 18480.

Answer:

 8.063 × 10²⁶

Step-by-step explanation:

From the given information:

Since the hacker knows that the character are lowercases letter, uppercases letter or numerical digits from (0-9).

Then, we have the total number of characters to be:

= 26 + 26 + 10

= 62

Now, for each of the 14 places, we can fill it up with 62 possible ways.

Thus, the probability that the hacker guesses in his first trial is:

[tex]=( \dfrac{1}{62})^{14[/tex]

[tex]=( 0.016129)^{14[/tex]

=  8.063 × 10²⁶

Answer:

40 miles.

Step-by-step explanation:

Given that the cost of renting a car in Hertz is $ 15 per day plus $ 0.50 for each mile traveled, while in Enterprise the cost is $ 25 per day plus $ 0.25 per mile traveled, to determine how many miles should be traveled to incur the same expenditure in both companies the following calculation must be made:

25 - 15 = 10

0.50 - 025 = 0.25

10 / 0.25 = 40

Therefore, to incur the same cost, 40 miles must be traveled, which is verified with the following calculation:

25 + 0.25 x 40 = 35

15 + 0.50 x 40 = 35

Answer:

Plan 2

Step-by-step explanation:

Plan 2 has an initial cost of $50 plus $5 for each hour thereafter.

Plan 1 has a steady cost of $29 per hour.

As an example, if a student is tutored for 5 hours, Plan 2's cost would be $50 + $5(5) = $75.

Plan 1's cost would be $29(5) = $145.
