In his garden tim plants the seed 3 1/4 in. Below the ground. After one month the tomato plant has grown a total of 11 1/2 in. How many inches is the plant above the​ ground?

Answers

Given:

Seed below the ground = [tex]3\dfrac{1}{4}\text{ in.}[/tex]

Total length of plant = [tex]11\dfrac{1}{2}\text{ in.}[/tex]

To find:

The length of plane above the ground.

Solution:

We have,

Plant below the ground = [tex]3\dfrac{1}{4}\text{ in.}[/tex]

Total length of plant = [tex]11\dfrac{1}{2}\text{ in.}[/tex]

Plant above the ground  = Total length of plant - Plant below the ground

[tex]=11\dfrac{1}{2}-3\dfrac{1}{4}[/tex]

[tex]=\dfrac{11\times 2+1}{2}-\dfrac{3\times 4+1}{4}[/tex]

[tex]=\dfrac{22+1}{2}-\dfrac{12+1}{4}[/tex]

[tex]=\dfrac{23}{2}-\dfrac{13}{4}[/tex]

Taking LCM, we get

[tex]=\dfrac{46-13}{4}[/tex]

[tex]=\dfrac{33}{4}[/tex]

[tex]=8\dfrac{1}{4}[/tex]

Therefore, the length of plant above the ground is [tex]8\dfrac{1}{4}\text{ in.}[/tex]

Answers

Answer:

Step-by-step explanation:

= 17-176+19+14+1723+3/9.

= 17-176+19+14+1723+0.33333333333333

A candy store sells 8-pound bags of mixed hazelnuts and cashews. If c pounds of cashews are in a bag, the price p of the bag can be found using the formula p= 2.59c + 1.72(8-c). If one bag is priced at $18.11, how many pounds of cashews does it contain ​

Answers

A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...

c=1 was already given as described. The store sells pound bags.

The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.

-

 

p=2.59%2Ac%2B1.72%288-c%29

You want to know the quantity of cashews if p=18.11 dollars per bag.

2.59c%2B1.72%2A8-1.72c=p

2.59c-1.72c=p-1.72%2A8

%282.59-1.72%29c=p-1.72%2A8

0.87c=p-13.76

A lab technician cuz a 12 inch piece of tubing into two pieces in such a way that one piece is two times longer than the other

Answers

The question is not complete. I have assumed you want to calculate the length of each piece.

Answer:

The shortest piece is 4 inches long

The longest piece is 8 inches long

Step-by-step explanation:

Equations

One piece of tubing is two times the other.

Let's call

x=the shortest piece of tubing

2x=the longest piece of tubing

The total length of the piece of tubing is 12 inches, thus:

x + 2x = 12

Simplifying:

3x = 12

Dividing by 3:

x = 12 / 3 = 4

x=4, and 2x=8, thus:

The shortest piece is 4 inches long

The longest piece is 8 inches long

what are the possible degrees for the polynomial function

Answers

Answer:

Degree of the polynomial function = 5

Step-by-step explanation:

Since, the given graph of a polynomial has the x-intercepts at x = -2, -0.5, 0.5, 1.5, 3

Therefore, the equation of the polynomials with zero roots will be,

y = (x + 2)(x + 0.5)(x - 0.5)(x - 1.5)(x - 3)

When we solve this expression highest degree of the variable x will be 5.

Therefore, the possible degree of the polynomial function = 5

Answer:

i was going to screenshot the answer bc i got it right but its

"odd 5 degrees or greater" :)
