Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. Let y represent the length

of each of the equal pieces of yarn that Julie decides to cut. What is the equation that can be used to determine the total length of all of the yarn that she ends up cutting, t? Is the graph of the equation continuous or discrete?

Answer:

\text{t}=4\text{y}+7.75, the graph will be continuous.

Step-by-step explanation:

Given: Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long, y represent the length of each of the equal pieces of yarn that Julie decides to cut, t represents total length of yarn.

To Find: Equation to determine the total length of yarn, and find if graph is discrete or continuous.

Solution:

total number of piece to be cut from yarn = 5

length of four equal pieces of yarn=\text{y}

length of fifth piece of yarn  =    7.75\text{inches}

now,

total length of yarn \text{t} is

              \text{t}=7.75+4\text{y}

rewriting equation

              \text{t}=4\text{y}+7.75

as length of piece of yarn \text{y} can be any real number, the graph will be continuous.

What is (-3 3/4) - (2 1/4)?
lisabon 2012 [21]

Answer: -6

Step-by-step explanation:

Rewrite the expression:

-3\frac{3}{4}-2\frac{1}{4}

Factor out the negative:

-3\frac{3}{4}-2\frac{1}{4}

-(3\frac{3}{4} +2\frac{1}{4})

Rewrite the sum:

-(3\frac{3}{4} +2\frac{1}{4})

-((3+2)+(\frac{3}{4}+\frac{1}{4}))

Calculate the sum:

-((3+2)+(\frac{3}{4}+\frac{1}{4}))

-(5+1)

Solve:

-(5+1)

-6

A 3-foot wife wood deck will be built around rectangular shaped pool that measures 15feet by 30feet. The resulting shape is also
lisov135 [29]

Answer:

$340

Step-by-step explanation:

The pool is 5 yards wide by 10 yards long, so adding the deck will make the total area 7 yards wide by 12 yards long, or ...

(7 yd)·(12 yd) = 84 yd^2

The pool itself is ...

(5 yd)·(10 yd) = 50 yd^2

so the area of the deck is ...

84 yd^2 -50 yd^2 = 34 yd^2

Wood for each of those square yards costs $10, so the total cost is ...

($10/yd^2)·(34 yd^2) = $340

How do I find this, what’s the formula to find the 20th term and can anyone explain the formula? Will award brainliest
harina [27]

Answer:

  • f(n) = n^2 +1
  • f(20) = 401

Step-by-step explanation:

The first differences of the sequence are ...

  • 5-2 = 3
  • 10-5 = 5
  • 17-10 = 7
  • 26-17 = 9
  • 37-26 = 11

Second differences are ...

  • 5 -3 = 2
  • 7 -5 = 2
  • 9 -7 = 2
  • 11 -9 = 2

The second differences are constant, so the sequence can be described by a second-degree polynomial.

We can write and solve three equations for the coefficients of the polynomial. Let's define the polynomial for the sequence as ...

  f(n) = an^2 + bn + c

Then the first three terms of the sequence are ...

  • f(1) = 2 = a·1^2 + b·1 + c
  • f(2) = 5 = a·2^2 +b·2 + c
  • f(3) = 10 = a·3^2 +b·3 +c

Subtracting the first equation from the other two gives ...

  3a +b = 3

  8a +2b = 8

Subtracting the first of these from half the second gives ...

  (4a +b) -(3a +b) = (4) -(3)

  a = 1 . . . . . simplify

Substituting into the first of the 2-term equations, we get ...

  3·1 +b = 3

  b = 0

And substituting the values for a and b into the equation for f(1), we have ...

  1·1 + 0 + c = 2

  c = 1

So, the formula for the sequence is ...

  f(n) = n^2 + 1

__

The 20th term is f(20):

  f(20) = 20^2 +1 = 401

Kendra bought a pieace of fabric that was 14 feet long .lisa bought a pieace of fabric that was 3 yards long .kendra wanted to c
storchak [24]
3 yards is equivalent to 9 feet, so you do 14 - 9 = 5 feet that she has to cut off.
Hope this helps!
