Step-by-step explanation:

You have to divide the miles by the hours drived and then divide 60 per the miles per hour

Answer:

5.2 hours, or 5 hours 12 minutes

Step-by-step explanation:

The distance is the same in both cases.  Since distance = rate (time),

time = distance / (rate).

Here, (6 hr)(52 mph) = (time)(60 mph, or

               312 mi         = (60 mph)(time), which gives us

(time) = (312 mi) / (60 mph) = 5.2 hours, or 5 hours 12 minutes

The Pythagorean theorem can only be applied to right triangles.

The Pythagorean theorem can be applied to right triangles only.

It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

So, while the Pythagorean theorem cannot be applied to every triangle, it can be used to find the length of one side of a right triangle given the lengths of the other two sides.

g=0.04 times d

Step-by-step explanation:

if you multiply 0.04 with every number under the d column then you’ll get the outcome of each number under g

The relationship between the number of gallons of gas that the car uses g, and the number of miles the car has driven d, is given by the equation g=0.04d. Since the values of g and d are linearly connected.

It is given that,

A table of content about the distance traveled by Rachel and the gas used for that distance.

The distance is given in miles as d and the gas is given in gallons as g

The values of d given in the table are 14, 70, 109, and 140. Here the order is increasing.

The values of g given in the table are 0.56, 2.8, 4.36, and 17.6. Here also the order is increasing.

Since the values of g and d are increasing linearly and g is depending on d, consider a linear equation as follows:

[tex]g=ad+c[/tex]

Finding a and c from the obtained equation:

From the table, when d=14, g=0.56 and d=70, g=2.8

On substituting these values in the equation we get

0.56=14a+c

2.8=70a+c

Subtracting 1st equation from the 2nd equation,

2.8-0.56=(70a+c)-(14a+c)

⇒ 2.24=56a

⇒ a=0.04

On substituting a value in any of the equations we get

0.56=(0.04)(14)+c

⇒ c=0

Thus, the required equation becomes g=0.04d. This says that the g and d values are linearly related to each other.

12 x 2 =24

Final answer:

Sound travels 2 miles in 10 seconds, giving it a speed of 0.2 miles per second. In 2 minutes, which equals 120 seconds, sound will travel 24 miles.

Explanation:

If sound travels 2 miles in 10 seconds, we can calculate the speed of sound by dividing the distance traveled by the time it took. To find out how far sound would travel in 2 minutes, we must first calculate its speed:

Speed = Distance / Time

Speed = 2 miles / 10 seconds

Speed = 0.2 miles/second

Now, let's convert 2 minutes to seconds since the speed is in miles per second:

2 minutes = 2 x 60 seconds = 120 seconds

Finally, we calculate how far sound travels in 2 minutes:

Distance in 2 minutes = Speed x Time

Distance in 2 minutes = 0.2 miles/second x 120 seconds

Distance in 2 minutes = 24 miles

Therefore, sound travels 24 miles in 2 minutes.

59-23 is 24

24 is the number of white cars so if 12 of the cars are blue, you just subtract 12 from 24 giving you 12 as the difference between white and blue cars

Final answer:

Sanjay has 12 more white toy cars than blue. There are 24 white cars in total after subtracting the number of blue and red cars from the total.

Explanation:

Sanjay has a total of 59 toy cars, of which 12 are blue and 23 are red. To find out how many toy cars are white, we need to subtract the number of blue and red cars from the total number of cars.

Total number of cars = 59

Number of blue cars = 12

Number of red cars = 23

Subtract the number of blue and red cars from the total:
59 - 12 - 23 = 59 - 35 = 24

So, there are 24 white cars.

To find out how many more white cars there are than blue cars, subtract the number of blue cars from the number of white cars:

24 (white cars) - 12 (blue cars) = 12

Therefore, there are 12 more white toy cars than blue toy cars.

Kenneth's average speed, we divide the total distance by the total time traveled. In this case, Keneth's average speed was approximately 52.91 miles per hour.

Kenneth's average speed, you can use the formula:

Average Speed = Total Distance/Total Time.

In this case, Kenneth drove 177.55 miles in 3 7/20 hours.

First, convert the mixed number time to an improper fraction:

3 7/20 = 67/20.

Now, substitute the values into the formula:

Average Speed = 177.55 / (67/20).

To divide by a fraction, multiply by its reciprocal:

Average Speed = 177.55 * (20/67).

Average Speed ≈ 52.91 miles per hour.

Therefore, Keneth's average speed was approximately 52.91 miles per hour.

Final answer:

The correct expression for the total square footage that Mandy painted is 4 × 10 squared, which totals 400 square feet when calculated.

Explanation:

The expression that represents the total square footage that Mandy painted when she paints four square walls that are ten feet on each side is 4 × 10 squared. To understand why, let us analyze a related problem where Marta has one square with a side length of 4 inches and another larger square with dimensions that are twice the first square, which means the side length of the larger square is 8 inches (4 inches × 2).

The area of a square is calculated by squaring its side length, so the smaller square has an area of 16 square inches (4 inches squared), and the larger square will have an area of 64 square inches (8 inches squared). This demonstrates that the area of the larger square is four times larger than the area of the smaller square, as the scale factor of the side lengths is squared to obtain the ratio of the areas.

Similarly, for Mandy's wall painting, each wall is 10 feet by 10 feet, so the area of one wall is 10 feet squared, which equals 100 square feet. Since there are four walls, the total area is 4 × 100 square feet, or 400 square feet in total. The correct expression for the total square footage Mandy painted is 4 × 10 squared.

Answer:

F(n) = 2n – 2

Step-by-step explanation:

The sequence 0, 2, 4, 6

First, let us determine if the sequence is arithmetic progression (A.P) or geometric progression (G.P)

This is illustrated:

Let us calculate the common difference (d)

Common difference (d) = 2nd term – first term

Common difference (d) = 3rd term – 2nd term

=> 2 – 0 = 2

=> 4 – 2 = 2

The common difference (d) = 2.

Common ratio (r) = 2nd term /1st term

Common ratio (r) = 3rd term /2nd term

=> 2/0 = undefined

=> 4/2 = 2

There is no common ratio.

Since we have a common difference, therefore the sequence is arithmetic progression.

Now, let us obtain an expression for the sequence.

This can be obtained by using the arithmetic progression formula as shown below:

F(n) = a + (n – 1)d

a is the first term

n is the number of term

d is the common difference.

The sequence 0, 2, 4, 6

The first term (a) = 0

Common difference (d) = 2

F(n) = a + (n – 1)d

F(n) = 0 + (n – 1)2

F(n) = 2n – 2

Answer:

X = 25

Step-by-step explanation:

To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.

Perimeter of an equilaterial triangle = 3 * s

S = side length

Perimeter = 150cm

150 = 3s

S = 150 / 3

S = 50cm

The side lengths are 50cm each since they are all equal.

To find x,

We have to divide the triangle equally into two different part.

Check the first attachment for better illustration on how the equilaterial triangle is.

Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.

From the right angle triangle, we can use pythagorean theorem to solve for x

a² = b² + c²

a = 50cm

b = 25cm

c = x√(3)

50² = [x√(3)]² + 25²

2500 = x² * 3 + 625

2500 - 625 = 3x²

1875 = 3x²

X² = 1875 / 3

X² = 625

X = √(625)

X = 25

The average rate of change will be given by 16a + b

Average Rate: A single rate that applies to real estate at many locations and is calculated as the weighted average of the various rates that are appropriate at each site.

It is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.

Given:

A general quadratic function of x is given by f(x) = ax² +bx +c

Now, the rate of change of the function f(x) is given by df(x)/ dx.

Therefore, df(x)/ dx = 2ax+ b

Now, the value of x ranges between 4 ≤ x ≤ 12.

So, at x= 4

df(x)/ dx = 2a(4) + b= 8a+ b

and, x= 12

df(x)/ dx = 2a(12) + b= 24a+ b

Thus, the average rate of change will be given by

(8a+ b) + (24a+ b) / 2

= 32a+ 2b/ 2

= 16a + b
