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:

She will have to earn $3,100

Step-by-step explanation:

6,600-3,500=3,100

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:

667.8 cm³

Step-by-step explanation:

To find the volume of a box;

simply multiply the length, width, and height - and you're good to go! For this case, the box is 9x7x10.6 cm, then the volume of a box is 667.80 cubic centimeters. For dimensions that are relatively small whole numbers, calculating volume by hand is easy. Therefore, the volume of the box is 667.8 inches cubed

Step-by-step explanation:

we know that

A=lxb

= 5 3/4 divided by 3 1/2

= 23/4 divided by 7/2

= 23/4 x 2/7

= 23/2 x 1/7

= 23/14

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

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

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

3017.54

Step-by-step explanation:

62/2=31

31 x 31 x 3.14=3017.54

Answer:

3017.54

Step-by-step explanation:

A = πr²

The radius is half of the diameter so you divide 2 into 62.

62/ 2 = 31

31 x 31 = 961

961 x 3.14 = 3017.54

Answer:

q5. £40.50

q6. didn't know that one sorry

q7. $114.24

Step-by-step explanation:

q5.  55% of £90

10% = 9

5% = 4.5

to get to 50% you do 10% x 5 = 50%

you then do 9 x 5 = 45

after that you add the 45 + 4.5 = 49 .50

after that you do £90 - 49.50 = £40.50

q7.  12% of 102

10% = 10.2

1% = 1.02

2% = 2.04

12% = 10.2 + 2.04 = 12.24

then you do 102 + 12.24 = 114.24
