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

Answer:(-3,2)

Step-by-step explanation:

The coordinates of the intersection point P of the diagonal CE and DH is  (-3,2)

A parallelogram is a simple quadrilateral with two pairs of parallel sides.

The vertices of the parallelogram are the corners of a polygon or the point where any two sides of the parallelogram meet

Given,

Vertices of the parallelogram CDEH= C(-5,5), D(2,5), E(-1,-1) and H(-8,-1)

Parallelogram diagonals are CE and DH

Since the diagonals of the parallelogram bisects each other, mid point of the CE and DH will be the intersecting point of diagonals

Using the mid point theorem,

Mid point of CE is,

C(-5,5) and E(-1,-1)

x= [tex]\frac{-5-1}{2}=-3[/tex]

y = [tex]\frac{5-1}{2}=2[/tex]

Mid point of the CE is (-3,2)

Hence, the coordinates of the intersection point P of the diagonal CE and DH is  (-3,2)

Answer: To factorize the quadratic expression

x2−9x+20, one must find the two numbers that add together to give 9, and multiply together to give 20. Those two numbers are 4 and 5, which factor into the expression

(x−4)(x−5). The signs are due to the fact that the first sign in the expression is a positive, which tells us that both signs must be the same, and the first sign is a negative, which means that, due to the positive sign in the expression, both signs are negative. To do the opposite, expanding, one must multiply

x by x, to get x2, add together 4 and 5 to get 9, and multiply them to get 20.

Step-by-step explanation:

To solve the inequality -0.2x+1.2<1.1, we subtract 1.2 from both sides and then divide by -0.2, which flips the inequality, resulting in x > 0.5.

To solve the inequality [tex]\frac{1.2}{-0.2x+1.2} < 1.1[/tex], we can follow a step-by-step process. First, we isolate the variable on one side. We'll subtract 1.2 from both sides of the inequality:

-0.2x+1.2-1.2 < 1.1-1.2

-0.2x < -0.1

Then we divide both sides by -0.2, remembering that dividing by a negative number will flip the inequality sign:

[tex]x > \frac{0.1}{0.2}[/tex]

x > 0.5

This means that for the inequality to hold true, x must be greater than 0.5. It's also important to note that by understanding the properties of inequalities and the operations performed on them, we can easily solve these mathematical statements.

Jenny was at bat 250 times.

The percentage refers to a number that is out of 100. When describing components of a whole in mathematics, percentages are employed similarly to fractions and decimals. When employing percentages, the idea is that there are 100 equal pieces that make up the whole. In addition, the sign "%" is used to indicate that a number is a percentage. In stores, online, in commercials, and in the media, percentages are nearly always present. A crucial talent that may help you save time and money and raise your employability is the ability to comprehend what percentages represent.

Given jenny hit 32% of the time when she was at bat and also she had 80 hits. let's assume she had a total of x hits. so 32% of x will be equal to 80.

From that,

32% x = 80

32*x = 80 * 100

x = 250

Answer:

15/-7

Step-by-step explanation:

slope is y(2) - y(1) / x(2) - x(1)

120-0/0-56

120/-56

simplified

The slope from point A to point B is found by dividing the rise by the run. With a rise of -120 and a run of 56, the slope is approximately -2.14, indicating a downward slope from A to B.

To find the slope from point A to point B, we can use the formula slope = rise/run. In this scenario, point A is at (0, 120) and point B is at (56, 0).

First, determine the rise, which is the change in the y-coordinates (vertical change). The rise is 0 - 120 = -120.

Next, determine the run, which is the change in the x-coordinates (horizontal change). The run is 56 - 0 = 56.

Now, we can calculate the slope: slope = rise/run = -120/56 = -2.14

the angles in a triangle will add up to 180 degrees

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

Let C represent number of CDs and D represent number of DVDs.

We have been that The Blast Off Music Company can make a total of 500 CDs and DVDs each day. We can represent this information in an equation as:

[tex]C+D=500...(1)[/tex]

[tex]C=500-D...(1)[/tex]

We are also told that it costs $8 to make each CD, so cost of C, CDs would be [tex]8C[/tex].

It costs $10 to make each DVD, so cost of D, DVDs would be [tex]10D[/tex].

We have been given that the company can spend $4800 for  production costs each day. This means that cost of C CDs and D DVDs will be equal to 4800. We can represent this information in an equation as:

[tex]8C+10D=4800...(2)[/tex]

Upon substituting equation (1) in equation (2), we will get:

[tex]8(500-D)+10D=4800[/tex]

[tex]4000-8D+10D=4800[/tex]

[tex]4000+2D=4800[/tex]

[tex]4000-4000+2D=4800-4000[/tex]

[tex]2D=800[/tex]

[tex]\frac{2D}{2}=\frac{800}{2}[/tex]

[tex]D=400[/tex]

Therefore, the company can make 400 DVDs in one day.

Upon substituting [tex]D=400[/tex] in equation (1), we will get:

[tex]C=500-D \Rightarrow 500-400=100[/tex]

Therefore, the company can make 100 CDs in one day.

Answer:

24 miles

Step-by-step explanation:

2 miles:10 seconds

? miles: 120 seconds

120 divided by 10 =12

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.

Answer:

suppose the number of 2 hours lessons are x and 1 hour lessons are y; thus,

2x+y=25

50x+30y=690

to get the values of x and y we solve the quadratic equation given;

from the top equation:

y=25-2x.......i

substituting i in our second equation we get:

50x+30(25-2x)=690

50x+750-60x=690

-10x=-60

thus;

x=6

hence we conclude that the number of 2 hours classes are 6 hours

Step-by-step explanation:

The expression representing the total charge for x hours of piano lessons is $20.25 + $5.25x, and for 15 hours, the total charge would be $99.

The correct expression to represent the total charge for a student who takes x hours of piano lessons in a month at $20.25 per month and $5.25 per hour is $20.25 + $5.25x. To calculate the amount the instructor would charge for 15 hours of lessons, we substitute x with 15:

Total charge for 15 hours = $20.25 + $5.25(15) = $20.25 + $78.75 = $99.

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
