Final answer:

Two people walking at 8 mph and 2 mph, respectively, will be 4.5 miles apart in 0.75 hours, or 45 minutes, because they are moving apart at a relative speed of 6 mph.

Explanation:

To calculate the time it will take for two people walking at different speeds to be 4.5 miles apart, we need to find the relative speed at which they are moving apart. The first person walks at 8 miles per hour (mph), and the second person walks at 2 mph. The relative speed is the difference in their speeds, which is 6 mph (8 mph - 2 mph).

We know that they want to be 4.5 miles apart. To find the time (t), we use the formula distance = speed × time, or rearranged to solve for time, time = distance / speed. Plugging in our values we get time = 4.5 miles / 6 mph, which simplifies to 0.75 hours. Therefore, it will take them 0.75 hours or 45 minutes to be 4.5 miles apart.

Answer:

[tex]\text{Surface area of cylinder is }302\thinspace m^2[/tex]    

Step-by-step explanation:

Given the cylinder with radius 3 m and height 13 m. we have to find the surface area of the cylinder to the nearest square meter.

Radius=3 m

Height=13 m

[tex]\text{Surface area of cylinder is }\\\\=2\pi r(r+h)\\\\=2\times\frac{22}{7}\times3(3+13)\\\\=\frac{132}{7}(16)=301,71\sim302\thinspace m^2[/tex]

In the analogy posed in the question, 'ready' is to 'prepared' as 'unmindful' is to 'neglectful'. That is, just as being ready is synonymous with being prepared, being unmindful is synonymous with being neglectful.

In English language, there is a type of analogy where a pattern of word pairs is presented and the pattern is to be completed with another pair of words that follows the same relation. In your question, 'ready is to prepared as unmindful is to....', therefore, we are trying to find a word that is to 'unmindful' as 'prepared' is to 'ready'.

When someone is 'ready', it means they are 'prepared'. In a similar way, when someone is 'unmindful', it means they are 'unprepared' or 'neglectful'. Therefore, 'unmindful is to neglectful' is the correct analogy to the given question, following the same pattern as the 'ready-prepared' analogy.

The value of x is 7.5, not 8. Hence, 8 is not the correct value of x.

The perimeter of a rectangle is expressed as:

Perimeter = 2( length + width )

Given that:
The width of the rectangular playhouse = x feet

The length = x + 3

Perimeter = 36 feet

To determine whether 8 is the value of x, we can set up an equation using the formula for the perimeter of a rectangle.

Perimeter = 2( length + width )

Plug in the given values:

36 = 2( (x+3) + x )

Solve for x:

36 = 2( 2x + 3 )

36 = 4x + 6

4x = 36 - 6

4x = 30

x = 30/4

x = 7.5

Based on the calculation, the value of x is 7.5, not 8.

8. the helmet costs $40, and the bicycle costs [tex]\( 5 \times 40 = 200 \).[/tex]

1. The sum of two consecutive even integers is 70. We can set up the equation as ( x + (x + 2) = 70 ), where ( x ) represents the first even integer. Solving for ( x ), we get ( x = 34 ) and ( x + 2 = 36 ). So, the numbers are 34 and 36.

2. Cat is 5 less than twice Dog's age, and Cat is 11 years old. Let's denote Dog's age as ( d ). The equation is ( 2d - 5 = 11 ). Solving for ( d ), we find ( d = 8 ). So, Dog's age is 8 years old.

3. The sum of three consecutive numbers is 46. Let's denote the smallest number as ( n ). The equation is ( n + (n + 1) + (n + 2) = 46 ). Solving for ( n ), we get ( n = 15 ). So, the numbers are 15, 16, and 17.

4. The equation for the sum of three consecutive even numbers totaling 198 can be written as ( n + (n + 2) + (n + 4) = 198 ), where ( n ) is the smallest even number. Solving for ( n ), we find ( n = 64 ). So, the numbers are 64, 66, and 68.

5. The equation for the sum of four consecutive numbers totaling 86 can be written as ( n + (n + 1) + (n + 2) + (n + 3) = 86 ). Solving for ( n ), we get ( n = 20 ). So, the numbers are 20, 21, 22, and 23.

6. The perimeter of a rectangle is 150 cm, and the length is 15 cm greater than the width. Let's denote the width as ( w ). The perimeter equation is ( 2(w + 15) + 2w = 150 ). Solving for ( w ), we find ( w = 30 ) and [tex]\( \text{length} = w + 15 = 45 \)[/tex]. So, the dimensions are length = 45 cm and width = 30 cm.

7. If the couch costs $825 and there's a 10% sales tax, the price before taxes can be found by dividing the price by [tex]\( 1 + \frac{\text{tax rate}}{100} \)[/tex]. So, the price before taxes is[tex]\( \frac{825}{1 + 0.10} = 750 \)[/tex].

8. Let's denote the cost of the helmet as ( h ). Since the bicycle costs 5 times as much as the helmet, we have[tex]\( \text{bike} = 5h \).[/tex] The total cost is $240, so [tex]\( \text{bike} + \text{helmet} = 240 \)[/tex]. Substituting[tex]\( \text{bike} = 5h \)[/tex], we get ( 5h + h = 240 ), which simplifies to ( 6h = 240 ). Solving for ( h ), we find ( h = 40 ). So, the helmet costs $40, and the bicycle costs [tex]\( 5 \times 40 = 200 \).[/tex]

m∠A=(2x-30)°

m∠B=(x+20)°

m∠C=(x-10)°

Sum of angles of triangle is 180°

So, m∠A+m∠B+m∠C=180°

So, (2x-30)°+(x+20)°+(x-10)°=180°

4x°-40°+20°=180°

4x°-20°=180°

Adding 20° on both sides

So, 4x°-20°+20°=180°+20°

4x°+0°=200°

4x°=200°

To find the value of x,

So, x=200/4

So, m∠A=(2*50-30)°=100°-30°=70°

m∠B=(x+20)°=50°+20°=70°

m∠C=(x-10)°=50°-10°=40°

The probability of rolling a number greater than 5 is 1/6.

Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.

The total number of faces that have a number greater than 5 = 6.

The total number of faces = 6.

Therefore, the probability of that can be found as shown below:

P( rolling a number greater than 5 ) = The total number of faces that have a number greater than 5/The total number of faces

= 1/6

We have found the probability.

Therefore, we have found that the probability of rolling a number greater than 5 is 1/6.

A function assigns the value of each element of one set to the other specific element of another set.

As the function of the height of the jump, Eva is given as h=-16t^2+20t+6. Now, in order to know if Eva will reach 14 feet height, we need to substitute the value of her height of Eva as 14 feet, therefore,

[tex]h=-16t^2+20t+6\\\\14=-16t^2+20t+6\\\\16t^2 - 20t+14-6=0\\\\16t^2 -20t + 8=0[/tex]

If we calculate the discriminant of the given quadratic equation, we will understand that the given quadratic equation has imaginary roots.
