Answer:

Step-by-step explanation:

the stick number is a knot invariant that intuitively gives the smallest number of straight "sticks" stuck end to end needed to form a knot. Specifically, given any knot K, the stick number of K, denoted by stick (K), is the smallest number of edges of a polygonal path equivalent to K.

The amount of time (t) in minutes it takes Jeff to mow an average sized yard is related to (n) the number of yards he mows. The

Sveta_85 [38]

Answer:

Jeff mows 9 yards of lawn in 30 minutes

Step-by-step explanation:

The equation that models the amount of time (t) in minutes it takes Jeff to mow an average sized yard is $t=2n+12$ , where n is the number of yards he mows.

To find the number of yards Jeff mows in 30 minutes, we set the equation to 30 and solve for n.

$\implies 2n+12=30$

Add -12 to both sides:

$\implies 2n=30-12$

$\implies 2n=18$

Divide both sides by 2

$\implies \frac{2n}{2}=\frac{18}{2}$

$\implies n=9$

Hence Jeff mows 9 yards of lawn in 30 minutes.

Solve for x. Enter your answer below as an improper fraction in lowest terms,

ICE Princess25 [194]

Answer:

x = $\frac{83}{36}$

Step-by-step explanation:

Given

x - 2 $\frac{1}{4}$ = $\frac{1}{18}$ ( change mixed number to improper fraction )

x - $\frac{9}{4}$ = $\frac{1}{18}$

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = $\frac{83}{36}$

PLEASE HELP ILL MARK YOU BRAINLIEST A student is assessing the correlation between the number of hours a plant receives sunlight

Studentka2010 [4]

Glad you ask!!!

Part A: ok so... linear correlation between the number of hours of sunlight that a plant receives and the eight it grows. so its like the amount of sunlight.

Part B: The function that is the best fit is y=3x+4

Part C: The slope shows the plant and the intersection with the y axis

Hope this helps :)

A football field is 120 yards by 53.333 yards. What is the area of the football field in acres if 1 acre=43560 ft?? Use correct

MA_775_DIABLO [31]

Answer:

<h2>The area of the pitch in an acre is 1.32 acre</h2>

Step-by-step explanation:

This problem requires to test our understanding of unit conversion, and we are expected to present our answer in an acre

first, let us convert from the yard to feet

given that the dimension of the pitch is

120 yards by

53.333 yard

1 yard is 3 foot

120 yards will give x

cross multiply we have

x1= 120*3

x1= 360 feet

also the second dimension is

x2= 53.333*3

x2= 159.999

x2= 159.999 feet

the area of the pitch is

area= 159.999*360

area= 57599.64 ft^2

Note: an acre is a unit for land area (1 acre=43560 ft^2)

if 1 acre = 43560 ft^2

x acre = 57599.64 ft^2

cross multiply we have

x acre = 57599.64/43560

x acre = 1.32 acre
