54 % of his free time is used on video games and internet

Solution:

Given that Gary spend 10 hours per week on the internet and 9 hours per week playing video games

Gary has 5 hours of free time per day

We know that, 1 week = 7 days

5 hours of free time per day, So for 1 week get,

7 x 5 = 35 hours of free time per week

Time spent per week on internet and video game = 10 + 9 = 19 hours per week

The percent of free time used on video games and internet is:

[tex]percent = \frac{\text{ Time spent per week on internet and video game }}{\text{ 35 hours of free time per week}} \times 100[/tex]

[tex]percent = \frac{19}{35} \times 100 = \frac{1900}{35}\\\\percent = 54.286 \approx 54[/tex]

Thus 54 % of his free time is used on video games and internet

Answer:

[tex](q+\frac{11}{2})^2-\frac{121}{4}[/tex]

Step-by-step explanation:

We have been given an expression [tex]q^2+11q[/tex]. We are asked to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.

We know that a perfect square trinomial is in form [tex]a^2+2ab+b^2[/tex].

To convert our given expression into perfect square trinomial, we need to add and subtract [tex](\frac{b}{2})^2[/tex] from our given expression.

We can see that value of b is 11, so we need to add and subtract [tex](\frac{11}{2})^2[/tex] to our expression as:

[tex]q^2+11q+(\frac{11}{2})^2-(\frac{11}{2})^2[/tex]

Upon comparing our expression with [tex](a+b)^2=a^2+2ab+b^2[/tex], we can see that [tex]a=q[/tex], [tex]2ab=11q[/tex] and [tex]b=\frac{11}{2}[/tex].

Upon simplifying our expression, we will get:

[tex](q+\frac{11}{2})^2-\frac{11^2}{2^2}[/tex]

[tex](q+\frac{11}{2})^2-\frac{121}{4}[/tex]

Therefore, our perfect square would be [tex](q+\frac{11}{2})^2-\frac{121}{4}[/tex].

Adding 121/4 to the equation will make it a perfect square to have [tex]q^2+11q + \frac{121}{4}[/tex]

The standard form of a quadratic equation is expressed as [tex]ax^2+bx+c=0[/tex]

Given the equation [tex]q^2+11q[/tex], we need to add a constant value that will make the expression a perfect square.

To complete the square, we will add the square of the half of the coefficient of q to the equation

Coefficient of q = 11

Half of the coefficient = 11/2

Square of the result = (11/2)² = 121/4

Adding 121/4 to the equation will make it a perfect square to have [tex]q^2+11q + \frac{121}{4}[/tex]

Step-by-step explanation:

Kyle:

Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.

Victor:

Victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed. If Victor spends 5 hours doing homework or reading, then he could play

[tex]30\cdot 5=150[/tex] minutes

that is

Hence, if both boys spend the same amount of time on homework and reading this week, then Kyle will have more time to play video games.

To determine if the speeds of the runners are in a proportional relationship, compare the ratios of their distances to their times.

In order for the speeds of the runners to be in a proportional relationship, their rates of covering distance should be consistent. In other words, the ratios of their distances to their times should be the same or equal.

For example, if Runner A ran 5 miles in 1 hour, and Runner B ran 10 miles in 2 hours, their speeds would be proportional because the ratio of distance to time is the same (5/1 = 10/2 = 5).

So, to determine which runners have proportional speeds, compare the ratios of their distances to their times and see if they are equal.

https://brainly.com/question/29765554

#SPJ12

Final answer:

Runners whose speeds are in a proportional relationship with each other are those who have the same average speed when the distance they run is divided by the time it took them. To find this, we use the average speed formula, which helps compare runners not only on an individual level but also in terms of speed fractions and distributions.

Explanation:

To determine which runners have speeds in a proportional relationship with each other, we need to use the concept of proportional relationships and the formula for average speed, which is calculated by dividing the distance by the time. If the ratio of distances to times for two runners is the same, then their speeds are proportional. For example, Runner A covering a distance of 10 miles in 2 hours and Runner B covering 5 miles in 1 hour both have an average speed of 5 miles per hour, which shows a proportional relationship.

Relating this to the details provided about the runners, for any pair of runners to have speeds that are in a proportional relationship, their speeds must be consistent or equivalent when calculated. The speed in miles per hour can be found by dividing the recorded distances by the recorded times. If multiple runners have the same result when distance is divided by the time, they are in a proportional relationship with each other in terms of speed.

Answer:

The width of the conference room = 18 feet

Step-by-step explanation:

Given:

Scale drawing of a planned office space is represented as

1 in : 6 feet

To find the width of the conference room if the width in the drawing is 3 inches.

Solution:

Scale is the representation of ratio of lengths in the drawing to the actual length.

The scale given here means that 1 inch length in the drawing corresponds to 6 feet length actually.

Thus, in order to find the actual length of 3 inches, we can use unitary method

If 1 inch in drawing corresponds to  = 6 feet

∴ 3 inches in drawing corresponds to = [tex]3\times 6 \ft[/tex] = 18 feet

Thus, width of the conference room = 18 feet

Divide miles ran by speed to get time:

2 miles / 8 miles per hour = 0.25 hours = 15 minutes.

2 miles / 6 miles per hour = 0.33 hours = 20 minutes.

20 minutes - 15 minutes = 5 minutes longer.

Final answer:

After calculating the time taken by each runner to complete the 2-mile race, we find that Arif took 5 minutes longer than Sharif to finish.

Explanation:

To determine how many minutes longer Arif took to complete the race compared to Sharif, we need to calculate the time each runner took to complete the 2-mile race. First, we calculate Sharif's time. Since speed is distance divided by time, we can rearrange the formula to find time: time = distance/speed.

For Sharif:

Distance = 2 miles

Speed = 8 miles per hour

Time = 2 miles / 8 mph = 0.25 hours

Convert Sharif's time from hours to minutes by multiplying by 60 minutes per hour (0.25 hours * 60 minutes/hour = 15 minutes).

For Arif:

Distance = 2 miles

Speed = 6 miles per hour

Time = 2 miles / 6 mph = 0.333... hours

Convert Arif's time from hours to minutes (0.333... hours * 60 minutes/hour = 20 minutes).

Now, to find the difference in time, subtract Sharif's time from Arif's time:

Difference = Arif’s time - Sharif's time = 20 minutes - 15 minutes = 5 minutes

Arif took 5 minutes longer than Sharif to complete the race.

Answer:

154 small cubes.

Step-by-step explanation:

We are given the dimensions of the cuboid as 72 cm × 66 cm × 56 cm.

So, length of the cuboid, l = 72 cm

Breadth of the cuboid, b = 66 cm

Height of the cuboid, h = 56 cm

Capacity of cuboid = l × b × h = 72 × 66 × 56 = 266112 cm³

Now, we have to find the number of small cubes of side 12 cm each that can be placed in the given cuboid.

Now, length of each side of each small cube, s = 12 cm

Volume of each small cube = s³ = (12)³ = 12 × 12 × 12 = 1728 cm³

For calculating the number of small cubes that can be placed in the given cuboid, we will divide the capacity of given cuboid by volume of each small cube.

Required number of cubes = [tex]\frac{Capacity\; of\; cuboid}{volume\; of\; each\; small\; cube}[/tex]

⇒ Number of cubes = [tex]\frac{266112}{1728}=154[/tex]

∴ 154 small cubes each of side 12 cm can be placed inside the given cuboid of dimensions 72 cm × 66 cm × 56 cm.

Question:

Which statements are true regarding the area of circle D? Select two options.

The area of the circle depends on the square of the radius.

The area of circle D is 36Pi centimeters squared.

The area of circle D is 324Pi centimetres squared

The area of the circle depends on the square of pi.

The area of the circle depends on the central angle.

Answer:

The following statements are true regarding the area of circle D:

Step-By-Step Explanation:

As we know, the formula for area of the circle is given by,

             [tex]A=\pi r^{2}[/tex]

Where, r = radius of the circle. In figure, CD = radius = 18 cm

So, the circle area can be measured as

            [tex]A=\pi(18)^{2}=324 \pi \mathrm{cm}^{2}[/tex]

From this, concluding that the circle area depends on radius square and its value is [tex]324 \pi \mathrm{cm}^{2}[/tex]. Hence, the statement given in option A and C are correct (reveals that option B is incorrect).  

As the Pi is constant, the circle radius cannot depend on Pi value and Option D also incorrect. The area of sector of circle only depends on ratio of central angle to entire circle (So option E also incorrect).

Answer:
