Can anyone help me with this please? It's the system of equations and I'm stuck...

Answer:

Hey!

Step-by-step explanation:-

Area of a circle's equation is π[tex]r^{2}[/tex] (pi [tex]r^{2}[/tex])

Since the radius is 2.1 and value of pi is 3.14cm,

area is

[tex]2.1^{2}[/tex] x 3.14

4.41 x 3.14

= 13.85

The area of this circle is 13.6.

Area of a circle is the region occupied by the circle in a two-dimensional plane.

The area of the circle is;

[tex]\rm Area \ of \ circle=\pi r^2\\\\Where\ r =radius[/tex]

The radius is 2.1.

Substitute all the values in the formula

[tex]\rm Area \ of \ circle=\pi r^2\\\\ Area \ of \ circle=3.14 \times 2.1^2\\\\ Area \ of \ circle=13.6[/tex]

Hence,  the area of this circle is 13.6.

Answer:

The last one

Step-by-step explanation:

Subtract the third quartile from the first quartile

The third box plot has the greatest interquartile range

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles.

The interquartile range (IQR) is the width of the box in the box-and-whisker plot.

For first box plot IQR=17-9

=8

For second box plot IQR=14-6

=8

For third box plot IQR=14-5

=9

For fourth box plot IQR=15-8

=7

Hence, the third box plot has the greatest interquartile range

108

Step-by-step explanation:

Answer:

108 yd^2

Step-by-step explanation:

Cut the figure in half. Make a rectangle and a square.

Now u got a 6ydx6yd square.

And a 6ydx12yd rectangle.

Figure out the square 1st.

6x6=36yd^2

Now figure out the rectangle.

6x12=72yd^2

Now add them together.

72+36=108yd^2

Answer: Elena used the "greater than" sign when she should have used the "less than sign".

The correct inequality is 8x + 58 < 500, where 8 is the amount of gigabytes taken up by a movie, x is the amount of movies, 58 is the amount of gigabytes already taken up, and 500 is the maximum storage capacity in gigabytes. The < sign denotes that 500 CANNOT be exceeded.

Step-by-step explanation:

Elena wrote the equation as 8x + 58 > 500, meaning that the amount of gigabytes MUST exceed 500. This does not make sense since a computer would still function even with less movies. Since the hard drive has a capacity of 500 GB, it cannot go higher, making the correct inequality 8x + 58 < 500.

Answer:

A. He has $22 because he spends $2 on snacks each day.

B. He spends $2 a day, in the table we can see it decreases by $2 each day, so he spends $2 every day.

C. Yes because the cost evenly decreases by $2, therefore it is a linear relationship.

D. ?

E. X ÷ Y = Z

X being the money, $22

Y being the days, 6

Z being the leftover money, $8

Just kidding! :)

A.

He starts off with 20$ because day 0 is the start.

B.

He spends 2$ each day because his money is decreasing by 2.

C.

The number of days and Jamal's money left is a linear relationship because he's spending 2 dollars a day, and at the end of day 10, he will have 0 dollars which means it's a decreasing linear equation.

Answer:

The answer of the other person

Step-by-step explanation:

Answer:

so for the first one, y=4x

meaning y = 4 times x

if y=1, x=4. y=2,x=8 y=3,x=12 etc..

same concept for the other ones.

y=x+6

x=1 then 1+6 = 7, so y=7

x=2 then 2+6 = 8, so y=8

etc

Answer:

See below

Step-by-step explanation:

7. Let's put points in this equation, 1, 2, and 3 will do.

y = 4x

y = 4(1)

y = 4

(1, 4)

y = 4x

y = 4(2)

y = 8

(2, 8)

y = 4x

y = 4(3)

y = 12

(3, 12)

Plot the points, and draw the line. See the first attached graph.

8. Let's put points in this equation, 1, 2, and 3 will do.

y = x + 6

y = 1 + 6

y = 7

(1, 7)

y = x + 6

y = 2 + 6

y = 8

(2, 8)

y = x + 6

y = 3 + 6

y = 9

(3, 9)

Plot the points, and draw the line. See the second attached graph.

9. Let's put points in this equation, 1, 2, and 3 will do.

y = 2x + 1

y = 2(1) + 1

y = 2 + 1

y = 3

(1, 3)

y = 2x + 1

y = 2(2) + 1

y = 4 + 1

y = 5

(2, 5)

y = 2x + 1

y = 2(3) + 1

y = 6 + 1

y = 7
