The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.



What questions do you need to answer this question? Please help

Answers

Answer:

The question we need to answer is what is the perimeter of the arena

Step-by-step explanation:

The question we need to answer is what total length of plank did the farmer ordered for the arena.

to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.

given data

length L= 115 1/4 ft = 115.25ft

width W= 63 1/2 = 63.5ft

perimeter= 2L+2W

perimeter= 2(115.25)+2(63.5)

perimeter= 230.5+127

perimeter= 357.5ft

This means that the farmer ordered a total length of 357.5ft of plank

Answers

Answer:

(10,2)

Step-by-step explanation:

To find the midpoint you have to:

Add both "x" coordinates then divide by 2.     12+8=20    20/2=10

Add both "y" coordinates then divide by 2.     10+(-6)=4   4/2=2

Answer:

a. [tex]\frac{5x}{(x+3)}[/tex]

b. [tex]\frac{5x}{(x+3)}[/tex]

Step-by-step explanation:

Given that:

a. [tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{5x(2x+6)}[/tex]

                        = [tex]\frac{50x^{2} }{10x^{2} +30x}[/tex]

                        = [tex]\frac{(50x)x}{(10x+30)x}[/tex]

                        = [tex]\frac{50x}{(10x+30)}[/tex]

                         = [tex]\frac{5x}{(x+3)}[/tex]

b. [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{10x(x+3)}[/tex]

                           = [tex]\frac{5x}{(x+3)}[/tex]

Therefore,

[tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{5x}{(x+3)}[/tex]

The mean mass of the 15 players in a rugby team is 85.2kg the mean mass of the team plus a substitute is 85.4kg what is the mass of the substitute ?

Answers

Answer:

88.4 kg

Step-by-step explanation:

Since we are given the mean we will need to multiply the mean by how many players there are on the team to find the total mass. (The second mean will be multiplied by 16 because it is the number of players on the team plus the substitute)

85.2 x 15 = 1,278

85.4 x 16 = 1,366.4

Subtract the first mass from the second because this will remove the mass of the 15 other players.

1366.4 - 1278 = 88.4

88.4 kg is the mass of the substitute.

simplify the square root of -15 times the square root of -20

[tex]b = 180 - 130 = 50[/tex]

i think this is the answer

Intro:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

<b and 50° are vertical angles so that means they are congruent.  So that means <b is 50.

<c and 50° are supplementary angles which means when you add them you should get 180. So if do 180 - 50 we will get 130. So that means <c is 130°.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Cost per bulb = $1.50

Cost per pot = $1.25

Bag of potting soil = $10.00

Budgeted amount to spend ≤ 20

Cost :

Bag of potting soil + (Cost per bulb + cost per pot)*number of tulip bulbs ≤ 20

$10 + ($1.50 + $1.25)t ≤ $20

$10 + 2.75t ≤ 20

$2.75t ≤ $20 - $10

$2.75t ≤ $10

t ≤ $10/$2.75

t ≤ 3.636

Hence, t = maximum number of tulip bulbs she can purchase is 3.636,

Since the exact number of tulip bulb she can purchase is a decimal which is impossible in an actual scenario. Hence, In other to spend not more than $20.00

t ≤ 3

this is an simplified or not?
