Answer:

Area=63.96

Step-by-step explanation:

Given data

A flower bed is 2 meters wide and 3 meters long

convert to feets

1m to feet 3.28084

2m to feet x

x= 3.28084*2

x=6.5ft

3m to feet

=3.28084*3

=9.84ft

Area= 6.5*9.84

Area=63.96

The fraction would be the part of the number over the actual number.

The fraction would be 60/90

Dividing both numbers by 30, the fraction reduces to 2/3

The answer is 2/3

Answer:

Solution given:

let fraction be x.

equation becomes:

60/x=90

doing crisscrossed multiplication

60=90x

dividing both side by 90

60/90=90x/90

x=60/90

reduced the term

x=⅔

⅔ is fraction of 60 to get 90

Step-by-step explanation:

5x-17 and 3x-11 are supplementary angles

They add up to 180 degrees

5x-17 + 3x - 11 = 180

8x - 28 = 180

8x= 208

x= 26

3x-11, 90, and 2y + 5 added together equal 180

3x-11 + 90 + 2y + 5 = 180

3(26) - 11 + 2y + 5 = 90

78 - 6 + 2y = 90

72 + 2y = 90

2y = 18

y = 9

I hope this helps!!!

Answer:

Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n.  After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.

Step-by-step explanation:

You know that Samuel's starting pay is $12.50/hr and for each season Samuel remains with the company, he receives a $0.35/hr raise.

Samuel's hourly rate after n seasons at the company will then be:

f(n)= 12.50 + 0.35*n

To determine the hourly rate after 18 seasons, you must replace the value n with 18:

f(18)= 12.50 + 0.35*18

Solving you get:

f(18)= 12.50 + 6.3

f(18)= 18.8

Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n.  After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.

Step-by-step explanation:

The number of people to paint the bridge is inversely proportional to the number of hours it takes.

(If there are more people, it will take less time etc.)

9 people can paint the bridge in 5 hours.

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.

Answer:

  (x, y) = (0, -3)

Step-by-step explanation:

Using the second equation, we can substitute for x in the first equation:

  6(y+3) -5y = 15

  y +18 = 15 . . . . . collect terms

  y = -3 . . . . . . . . . subtract 18

Using the second equation:

  x = y +3 = (-3) +3 = 0

The solution is ...

  x = 0

  y = -3

Answer:

$1,956.95

Step-by-step explanation:

The school bought 47 sandwiches for $40.60

= 47 × 40.60

= 1,908.2

They also bought 39 bags of chips for $1.25

= 1.25×39

= 48.75

Therefore the total amount spent can be calculated as follows

= 48.75 + 1,908.2

= 1,956.95

Hence the total amount spent by the school is $1,956.95

Answer:

I believe it is 5 I'm not sure if it is right

Answer:

A. 5

Step-by-step explanation:

use pythagorean theorem: a^2 + b^2 = c^2

but since we are finding the value of A; we'll use a= (square root) c^2 - b^2

A= 13^2- 12^2

A= 169 - 144

A= 25

A= 5 ( because we square root 25)

Answer:

Theres no equation here?

Step-by-step explanation:

Answer:

(a) h = 160 - 5·x

(b) V = 4·x² × h = 4·x² × (160 - 5·x) = 640·x² - 20·x³ = 20·x²·(32 - x)

∴ V = 20·x²·(32 - x)

Step-by-step explanation:

(a) The given dimensions of the cuboid (rectangular prism) are;

'4·x' meters by 'x' meters by 'h' meters

Let the 4·x meters represent the length, 'l', of the cuboid, let the x meters represent the width, 'w', of the cuboid, and let the h meters represent the height 'h' of the cuboid

Therefore, we are given that the cuboid is a wire cage, with the total length of the sides (edges) of the cuboid equal to 640 meters

Therefore, the sum of the edges are;

Top(4·x + x + 4·x + x) + Side(h + h + h + h) + Bottom(4·x + x + 4·x + x) = 640

20·x + 4·h = 640

∴ h = (640 - 20·x)/4 = 160 - 5·x

h = 160 - 5·x

(b) The volume of a cuboid, V, is given as follows;

V = The area of the base of the cuboid × The height of the cuboid

The area of the base of the cuboid = l × w = 4·x × x = 4·x²

The height of the cuboid = h = 160 - 5·x

∴ V = 4·x² × (160 - 5·x) = 640·x² - 20·x³

V = 640·x² - 20·x³ = 20·x²·(32 - x)

∴ V = 20·x²·(32 - x) QED.

The LCM is 6,46,800

The smallest positive integer that is divisible by both a and b is the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, which is typically denoted by lcm (a, b) in arithmetic and number theory.

Given A = 2³ x 5 x 7² x 11

B = 2⁴ x 7 x 11

C = 3 x 5²

LCM(A,B,C) = 2³ x 5 x 7² x 11 x 2 x 3 x 5

LCM(A,B,C) = 6,46,800

Hence LCM(A,B,C) is 6,46,800

Average:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Given,

For double queen beds increment is $120 x 3% => $120 x (3/100) => 3.6.

The total rate for double queen beds = $120 + $3.6 = $123.6

For king beds increment is $140 x 3% => $140 x (3/100) => 4.2

The total rate for double queen beds = $140 + $4.2 = $144.2

For junior suite increment is $210 x 3% => $210 x (3/100) => 6.3

The total rate for junior suite = $210 + 6.3 = $216.3

For luxury suite increment is $320 x (3/100) => 9.6

The total rate for luxury suite = $320 + 9.6 = $329.6

The average rate =  ($123.6 + $144.2 + $216.3 + $329.6) / 4

=> $203.425 i.e., $203
