Awire 4 1/2 feet long is been cut into small pieces of wire each one and 1/4 feet long what is the maximum number of smaller pie
77julia77 [94]

Answer:

3

Step-by-step explanation:

Wire is 4 1/2 feet, or 4.5 feet.

Each smaller wire needs to be 1 1/4 feet, or 1.25 feet.

<em>How many whole 1.25 feet wire can we have from total of 4.5 feet wire?</em>

<em />

Let's divide:

\\frac{4.5}{1.25}=3.6

<em>thus we can have 3 whole "1.25 feet long" wire and fractional amount.</em>

<em />

<em>Hence, maximum number of smaller pieces is 3</em>

Show the factors of 5 x y square + 7 x square y by tree diagram​
zlopas [31]

Answer:

Answer:

Domain = {x /x ≥ -7}

Step-by-step explanation:

The given function y =

Inside the square, negative will not come.

First let's find the domain. x + 7 must be greater than or equal to 0.

x + 7 ≥ 0

Solving x, we get

x ≥ -7

Domain = {x /x ≥ -7}

Hope this will help you.

if a right triangle has one side measuring 3√2 and another side measuring 2√3, what is the length of the hypotenuse?
lina2011 [118]

Answer:

<h2>\sqrt{30}</h2>

Step-by-step explanation:

Given,

Perpendicular ( p ) = 3√2

Base ( b ) = 2√3

Hypotenuse ( h ) = ?

Now, let's find the length of the hypotenuse:

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

plug the values

{h}^{2}  =  {(3 \sqrt{2} )}^{2}  +  {(2 \sqrt{3} )}^{2}

To raise a product to a power, raise each factor to that power

{h}^{2}  = 9 \times 2 + 4 \times 3

Multiply the numbers

{h}^{2}  = 18 + 12

Add the numbers

{h }^{2}  = 30

Take the square root of both sides of the equation

h =  \sqrt{30}

Hope this helps...

Best regards!!
