Solution

Correct option is E)

To find the solution we split the inequality ∣2x+7∣>11 in two inequality ∣2x+7∣>11 and ∣2x+7∣<−11

⇒2x+7>11

⇒2x>11−7

⇒2x>4

⇒x>2

⇒2x+7<−11

⇒2x<−11−7

Answer:

1 kg of mushrooms costs £2.7.

Step-by-step explanation:

Step 1: Write equations.

Let a be the cost of apples per kg and m the cost of mushrooms per kg.

First equation: Ibrar buys 3 kg of apples. He also buys 0.4 kg of mushrooms. The total cost is £6.93.

[tex]3a + 0.4m = 6.93[/tex]

Second equation: 1 kg of apples cost £1.95.

[tex]a = 1.95[/tex]

Step 2: Solve the system of equations.

1) [tex]3a + 0.4m = 6.93[/tex]

2) [tex]a = 1.95[/tex]

Substitute a in the first equation with a from second.

[tex]3a + 0.4m = 6.93\\3(1.95) + 0.4m = 6.93[/tex]

Solve for m.

[tex]5.85 + 0.4m = 6.93\\0.4m = 6.93 - 5.85 \\0.4m = 1.08\\m = \frac{1.08}{0.4}\\m = \text{\£}2.7[/tex]

The cost of 1 kg of mushrooms is £2.7.

Two or more expressions with an Equal sign is called as Equation.

Given that Ibrar buys 3kg of apples

Ibrar buys 0.4kg of mushrooms.

The total cost is £6.93

3x+0.4y=6.93...(*)

1kg of apples cost is £1.95

x=1.95

Substitute the value of x in *

3(1.95)+0.4y=6.93

5.85+0.4y=6.93

Subtract 5.85 on both sides

0.4y=6.93-5.85

0.4y=1.08

Divide both sides by 0.4

y=2.7

Hence, the cost of 1 kg of mushrooms is £2.7.

Step-by-step explanation:

If the average rate of change is 18, then the value of the x is √(13/5). Then the correct option is B.

It's an average of how far the functions changed per unit throughout that time period.

Let f be the function given by f(x) = x³ + 5x.

Then the value in the closed interval [1,3] will be

The instantaneous rate of change will be

[tex]f'(x) = 3x ^2 + 5[/tex]

Then the average rate of change will be

[tex]= \dfrac{f(3) - f(1)}{3-1} \\\\= \dfrac{(3^3 + 5\times 3) - (1^3 + 5 \times 1)}{3-1}\\\\= 18[/tex]

Then we have

3x² + 5 = 18

Then the value of x will be

[tex]\begin{aligned} \rm 3x^2 + 5 &= 18\\\\\rm x &= \sqrt{\dfrac{13}{3}} \end{aligned}[/tex]

Cartographers use trigonometry for topographic mapping, while navigators use it to direct navigation, helping to identify location and distance.

Surveyors, on the other hand, use trigonometry to measure spatial data, such as height and angles of the land and urban and rural georeferencing.

Trigonometry studies the relationships between the sides and angles of a triangle. This calculation instrument is used for studies in various fields of scientific knowledge, such as the study of phenomena in mechanics, engineering and medicine.

Therefore, there are several applications for trigonometry in social daily life, being an instrument that helps in obtaining scientific knowledge and development of society.

Answer:

This was my answer, I did a lot of research for it

Step-by-step explanation:

According to wonderworksonline.com, "cartographers use the laws of plane trigonometry". This is used for topographical mapping which is a map that includes detailed, accurate landmarks.

Navigators use trigonometry to find directions. According to byjus.com, "with the help of a compass and trigonometric functions in navigation, it will be easy to pinpoint a location and also to find distance as well to see the horizon."

Trigonometry is used in land surveying to measure to height and angles of the land. According to prezi.com, "it can be used to measure the elevation from a certain point to a mountain, the distance between two trees, and distances across lakes."

Another profession that uses trigonometry is astronomy. Trigonometry is used to measure the distance between stars and planets. According to mytutor.co.uk, "this mathematical technique is also used by NASA scientists today when they design and launch space shuttles and rockets."

Trigonometry plays an important part in our everday lives. Without trigonometry, we wouldn't have GPS to navigate us. Trigonometry is also used by flight engineers to decide take off paths. Trigonometry is also used in the medical field for ultrasounds, the process of building prosthetic legs and arms, and surgeries.

Answer:

the 4th option because 24 months times the amount plus the 39.99 to set up would get you a final answer

Answer:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account

Step-by-step explanation:

Knowing that it given:

What is the cost(c) month for using the service for 24 months?

That means "Cost = c"

That leads us to the answer:

"Where c is the cost to set up an account"

We also know that we are finding for the 24 months thus 24c.

That leads us to

24c + 39.99 = 351.75 and 39.99/24c = 351.75

Hence, the answers are:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account

△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.

Step-by-step explanation:

If L' were (-3,-4), it would be a reflection of L across the x-axis as J' and K' are with respect to J and K. Unfortunately, because it is not, the side lengths J'L' and K'L' of triangle J'K'L' are different from those of triangle JKL. This ensures the triangles JKL and J'K'L' are not congruent.

The average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

From the question, we are to determine Keane's average speed

Average speed is given by the formula,

Average speed = Distance / Time

Distance travelled = 180 miles

Now, we will calculate the time spent

From the given information,

He leaves his home at 09:30 and arrives in Liverpool at 12:42

09:30 to 12:42 is 3 hours 12 minutes

∴ Time = 3 hours 12 minutes = 3 + (12/60) hours = 3.2 hours

Thus,

Average speed = 180 / 3.2

Average speed =  56.25 mph (miles per hour)

Hence, the average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

An equation is formed of two equal expressions. The cost of a new book is $7.43, while the cost of an old book is $8.86.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of 14 used books is $124. Therefore, the cost of a single used book is,

Cost of single used book(u) = 124/14 = $8.86

Also, the cost of 12 used books and 4 new books is $136. Therefore, the equation can be written as,

12u + 4n = 136

12(8.85) + 4n = 136

106.2 + 4n = 136

n = $7.43

Hence, the cost of a new book is $7.43, while the cost of an old book is $8.86.
