Answer:

D

Step-by-step explanation:

The system of linear equation 25.75x + 4.25y = 150 represents x and y as the number of backpacks and the number of notebooks.

In a system of the linear equation there exist if and only if the number of unknowns and the number of the equation is equal.

Total item purchased = 10

The cost of backpacks = $25.75

The cost of notebooks = $4.25

The total cost of the items is $150.

Let x be the number of backpacks and y be the number of notebooks so, the system of equations.

25.75x + 4.25y = 150

Therefore, the system of linear equation 25.75x + 4.25y = 150 represents x and y as the number of backpacks and the number of notebooks.

Answer:

The area of the sector of the circle is approximately

Step-by-step explanation:

The given parameters of the circle having a shaded sector are;

The radius of the circle, r = 4 meters

The measure of the arc bounding the sector = 135°

The area of a sector of a circle, 'A', is given as follows;

[tex]A = \dfrac{\theta}{360 ^{\circ}} \times \pi \times r^2[/tex]

Therefore, the area, 'A' of the given sector of the circle, is given as follows;

[tex]A = \dfrac{135 ^{\circ}}{360 ^{\circ}} \times \pi \times (4\ cm)^2 \approx 18.85 \ cm^2[/tex]

The area of the sector of the circle, with radius 4 cm and bounded by an arc, A ≈ 18.82 cm².

Answer:

1) I and III

Step-by-step explanation:

The equation of an exponential function is given by:

y = abˣ

where x is an independent variable, y is a dependent variable, a is the initial value of y (that is value of y at x = 0), b is greater than 1 for an exponential growth while b < 1 for an exponential decay.

Given that x represent years and P(x) represent population. 2013 is represented by x= 0, hence:

At the year 2013 (x = 0), the population is 3810, hence a = 3810.

The equation becomes:

P(x) = 3810(b)ˣ

At 2014 (x = 1), the population is 3943. Hence:

3943 = 3810(b)¹

3810b = 3943

b = 1.035.

Therefore a = 3810, b = 1.035. The correct option is 1) I and III

Since b > 1, this is an exponential growth.

Step-by-step explanation:

Pelican Beach has a median temperature above 80 degrees and the smallest interquartile range.

'A boxplot is a standardized way of displaying the distribution of data based on a five number summary, minimum, first quartile, median, third quartile, and maximum. It can tell us about the outliers and what their values are.'

According to the given problem,

In the given box plots, Whispering Palms and Pelican Beach has a median temperature of above 80 degrees. The median is the middle-most line that divides the box plot into two parts. Their median is approximately 85 degrees.

The interquartile range is the difference between the end points of the box plot.

Pelican Beach has the smallest interquartile range since the difference between the end points is less than the interquartile range of Whispering Palms.

Hence, we can conclude, Pelican Beach ahs the median temperature above 80 degrees and the smallest interquartile range.

Answer:

I'm pretty sure it is D

Step-by-step explanation:

sry if I am wrong

The fourth graph is representing the inequality x ≤ 7, so option D is correct.

Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal.

Given:

The inequality = x ≤ 7,

As this inequality representing the value of x is less than 7 or can be equal to 7, In this graph

Option D is representing the inequality, as the graph is suggesting x can be equal to 7 or less than 7.

Therefore, the fourth graph is representing the inequality x ≤ 7.

Answer:

Step-by-step explanation:

The roots of the quadratic equation below using the quadratic formula are option A. [-9 ± √105 ] / 6.

Given is a quadratic equation,

3x² + 9x - 2 = 0

Quadratic formula to find the roots of a general quadratic equation ax² + bx + c is,

x = [-b ± [tex]\sqrt{b^2-4ac}[/tex] ] / 2a

Here a = 3, b = 9 and c = -2.

Substituting the values,

x = [-9 ± [tex]\sqrt{9^2-(4)(3)(-2)}[/tex] ] / (2 × 3)

  = [-9 ± [tex]\sqrt{81+24}[/tex] ] / 6

  =  [-9 ± √105 ] / 6

So the roots are [-9 ± √105 ] / 6.

Step-by-step explanation:

Just trust me the answer is A lol.

Answer:

Length of AC = 23.75 unit

Step-by-step explanation:

Give that BD II CE

Length of AB = 10 unit

Length of AD = 16 unit

Length of DE = 22 unit

Find:

Length of AC

Computation:

Give that BD II CE

So,

AB / BC = AD / DE

AB / [AC - 10] = AD / DE

10 / [AC - 10] = 16 / 22

[10][22] = [AC - 10][16]

220 = 16AC - 160

16AC = 220 + 160

16AC = 380

AC = 23.75

Length of AC = 23.75 unit
